A new strategy for the surgical treatment of aortic coarctation associated with ventricular septal defect in infants using an absorbable pulmonary artery band. (1/490)

OBJECTIVES: We propose a new strategy using coarctation repair together with a polidioxanone absorbable pulmonary artery banding to limit operative risk and to spare infants with aortic coarctation subsequent operations. BACKGROUND: The alternative for the surgical management of aortic coarctation associated with ventricular septal defect (VSD) is single-stage repair versus coarctation repair with or without banding of the pulmonary artery. METHODS: Eleven infants (mean weight 2,560 +/- 1,750 g, range 1,320 to 3,800 g) underwent a coarctation repair with a polydioxanone banding. Seven had a trabecular and four a perimembranous VSD. The mean size of the VSD was 5 +/- 0.7 mm (range 4 to 7 mm). The systolic pulmonary pressure was >80% of the aortic pressure in all. The pulmonary band was tightened until the systolic pulmonary pressure fell below 50% of the aortic pressure. RESULTS: There were no hospital deaths. The reabsorption of the banding was complete after 5.7 months in all patients (3 to 6.5 months). The VSD closed completely in four infants and partially in six, in whom the pulmonary artery pressure was normal without evidence for significant left-to-right shunt. One patient with a large trabecular VSD underwent surgical closure of his defect after four months. Finally, a subsequent open-heart surgery could be avoided in 91% (10/11) of patients. CONCLUSIONS: Provided the VSD belongs to types prone to close spontaneously, this policy may reduce the number of surgical procedures per infant as well as in-hospital mortality and morbidity rates. It should be proposed as an alternative to more complex procedures.  (+info)

Rotational acetabular osteotomy using biodegradable internal fixation. (2/490)

We used biodegradable poly-L-lactide screws in rotational acetabular osteotomy in 41 hips of 41 patients, and studied the complications after an average follow-up of 4.9 years (range 1.0-7.7 years). There were 39 females and 2 males, their average age at the time of the operation was 32 years (range 12-55 years). A small subcutaneous abscess appeared around the non-absorbable sutures in 2 patients after surgery. There was 1 case of thrombophlebitis and 1 of local dermatitis. The small subcutaneous abscess resolved after the removal of the suture material in the 2 cases, and the thrombophlebitis resolved with aspirin. The local dermatitis persisted but was cured by local steroid therapy over 5.8 years. The incidence of local dermatitis after the use of biodegradable implants should be further investigated.  (+info)

Inhibition of neointima formation after experimental coronary artery stenting: a new biodegradable stent coating releasing hirudin and the prostacyclin analogue iloprost. (3/490)

BACKGROUND: To minimize acute stent thrombosis and development of restenosis, stents coated with biodegradable and nonbiodegradable polymers have been proposed to serve as sustained-release drug carriers. METHODS AND RESULTS: In both a sheep and a pig model, we examined the vascular response to standard and high-pressure implantation of coronary Palmaz-Schatz stents coated with a 10-microm layer of polylactic acid (MW 30 kDa) releasing recombinant polyethylene glycol (r-PEG)-hirudin and the prostacyclin analogue iloprost, both drugs with antithrombotic and potentially antiproliferative effects. Study observation time was 28 days. Between the corresponding stent groups, no differences were observed with regard to preplacement and postplacement implantation parameters. The morphometric analysis demonstrated that the coating was associated with a greater lumen diameter through a reduction in the mean restenosis area by 22.9% (P<0.02) in the standard-pressure model (sheep) and by 24.8% (P<0.02) in the overstretch pig model compared with uncoated control stents without inducing a local inflammatory response. CONCLUSIONS: The results from this study demonstrate beneficial effects of a polymeric stent coating with polylactic acid releasing r-PEG-hirudin and iloprost on the development of restenosis after coronary stent placement at 4 weeks, independent of the extent of vascular injury. Future studies are proposed to investigate the integration of other substances to further enhance the potential of the stent coating on reducing neointimal formation.  (+info)

In situ tumor vaccination with interleukin-12-encapsulated biodegradable microspheres: induction of tumor regression and potent antitumor immunity. (4/490)

An alternative technology for the local and sustained delivery of cytokines to tumors for cancer immunotherapy was evaluated and shown here to induce tumor regression, suppression of metastasis, and development of systemic antitumor immunity. Treatment of tumor-bearing BALB/c mice with a single intratumoral injection of biodegradable polylactic acid microspheres loaded with recombinant interleukin-12 (IL-12) promoted complete regression of the primary tumor and prevented the metastatic spread to the lung. Mice that experienced tumor regression after being treated rejected a subsequent challenge with live tumor cells, which indicated the development of systemic antitumor immunity. In situ tumor vaccination, ie., injection of IL-12 microspheres into existing tumors, was superior to vaccination of mice with mixtures of tumor cells (live or irradiated) and IL-12 microspheres in inducing systemic antitumor immunity. The sustained release of IL-12 from the microspheres was superior to bolus injection of free IL-12, and intratumoral delivery of microspheres was more effective than other routes of administration. These studies establish the utility of biodegradable polymer microspheres as a clinically feasible alternative to systemic cytokine therapy and cytokine gene-modified cell vaccines for the treatment of neoplastic disease.  (+info)

Soluble biodegradable polymer-based cytokine gene delivery for cancer treatment. (5/490)

Transgene expression and tumor regression after direct injection of plasmid DNA encoding cytokine genes, such as mIL-12 and mIFN-gamma, remain very low. The objective of this study is to develop nontoxic biodegradable polymer-based cytokine gene delivery systems, which should enhance mIL-12 expression, increasing the likelihood of complete tumor elimination. We synthesized poly[alpha-(4-aminobutyl)-l-glycolic acid] (PAGA), a biodegradable nontoxic polymer, by melting condensation. Plasmids used in this study encoded luciferase (pLuc) and murine interleukin-12 (pmIL-12) genes. PAGA/plasmid complexes were prepared at different (+/-) charge ratios and characterized in terms of particle size, zeta potential, osmolality, surface morphology, and cytotoxicity. Polyplexes prepared by complexing PAGA with pmIL-12 as well as pLuc were used for transfection into cultured CT-26 colon adenocarcinoma cells as well as into CT-26 tumor-bearing BALB/c mice. The in vitro and in vivo transfection efficiency was determined by luciferase assay (for pLuc), enzyme-linked immunosorbent assay (for mIL-12, p70, and p40), and reverse transcriptase-polymerase chain reaction (RT-PCR) (for Luc and mIL-12 p35). PAGA condensed and protected plasmids from nuclease degradation. The mean particle size and zeta potential of the polyplexes prepared in 5% (w/v) glucose at 3:1 (+/-) charge ratio were approximately 100 nm and 20 mV, respectively. The surface characterization of polyplexes as determined by atomic force microscopy showed complete condensation of DNA with an ellipsoidal structure in Z direction. The levels of mIL-12 p40, mIL-12 p70, and mIFN-gamma were significantly higher for PAGA/pmIL-12 complexes compared to that of naked pmIL-12. This is in good agreement with RT-PCR data, which showed significant levels of mIL-12 p35 expression. The PAGA/pmIL-12 complexes did not induce any cytotoxicity in CT-26 cells as evidenced by 3- inverted question mark4, 5-dimethylthiazol-2-yl inverted question mark-2,5-diphenyltetrazolium bromide assay and showed enhanced antitumor activity in vivo compared to naked pmIL-12. PAGA/pmIL-12 complexes are nontoxic and significantly enhance mIL-12 expression at mRNA and protein levels both in vitro and in vivo.  (+info)

Early in vivo experience with tissue-engineered trileaflet heart valves. (6/490)

BACKGROUND: Tissue engineering is a new approach in which techniques are being developed to transplant autologous cells onto biodegradable scaffolds to ultimately form new functional autologous tissue. Workers at our laboratory have focused on tissue engineering of heart valves. The present study was designed to evaluate the implantation of a whole trileaflet tissue-engineered heart valve in the pulmonary position in a lamb model. METHODS AND RESULTS: We constructed a biodegradable and biocompatible trileaflet heart valve scaffold that was fabricated from a porous polyhydroxyalkanoate (pore size 180 to 240 microm; Tepha Inc). Vascular cells were harvested from ovine carotid arteries, expanded in vitro, and seeded onto our heart valve scaffold. With the use of cardiopulmonary bypass, the native pulmonary leaflets were resected, and 2-cm segments of pulmonary artery were replaced by autologous cell-seeded heart valve constructs (n=4). One animal received an acellular valved conduit. No animal received any anticoagulation therapy. Animals were killed at 1, 5, 13, and 17 weeks. Explanted valves were examined histologically with scanning electron microscopy, biochemically, and biomechanically. All animals survived the procedure. The valves showed minimal regurgitation, and valve gradients were <20 mm Hg on echocardiography. The maximum gradient was 10 mm Hg with direct pressures. Macroscopically, the tissue-engineered constructs were covered with tissue, and there was no thrombus formation on any of the specimens. Scanning electron microscopy showed smooth flow surfaces during the follow-up period. Histological examination demonstrated laminated fibrous tissue with predominant glycosaminoglycans as extracellular matrix. 4-Hydroxyproline assays demonstrated an increase in collagen content as a percentage of native pulmonary artery (1 week 45.8%, 17 weeks 116%). DNA assays showed a comparable number of cells in all explanted samples. There was no tissue formation in the acellular control. CONCLUSIONS: Tissue-engineered heart valve scaffolds fabricated from polyhydroxyalkanoates can be used for implantation in the pulmonary position with an appropriate function for 120 days in lambs.  (+info)

Functional living trileaflet heart valves grown in vitro. (7/490)

BACKGROUND: Previous tissue engineering approaches to create heart valves have been limited by the structural immaturity and mechanical properties of the valve constructs. This study used an in vitro pulse duplicator system to provide a biomimetic environment during tissue formation to yield more mature implantable heart valves derived from autologous tissue. METHODS AND RESULTS: Trileaflet heart valves were fabricated from novel bioabsorbable polymers and sequentially seeded with autologous ovine myofibroblasts and endothelial cells. The constructs were grown for 14 days in a pulse duplicator in vitro system under gradually increasing flow and pressure conditions. By use of cardiopulmonary bypass, the native pulmonary leaflets were resected, and the valve constructs were implanted into 6 lambs (weight 19+/-2.8 kg). All animals had uneventful postoperative courses, and the valves were explanted at 1 day and at 4, 6, 8, 16, and 20 weeks. Echocardiography demonstrated mobile functioning leaflets without stenosis, thrombus, or aneurysm up to 20 weeks. Histology (16 and 20 weeks) showed uniform layered cuspal tissue with endothelium. Environmental scanning electron microscopy revealed a confluent smooth valvular surface. Mechanical properties were comparable to those of native tissue at 20 weeks. Complete degradation of the polymers occurred by 8 weeks. Extracellular matrix content (collagen, glycosaminoglycans, and elastin) and DNA content increased to levels of native tissue and higher at 20 weeks. CONCLUSIONS: This study demonstrates in vitro generation of implantable complete living heart valves based on a biomimetic flow culture system. These autologous tissue-engineered valves functioned up to 5 months and resembled normal heart valves in microstructure, mechanical properties, and extracellular matrix formation.  (+info)

Scleral plug of biodegradable polymers containing ganciclovir for experimental cytomegalovirus retinitis. (8/490)

PURPOSE: To evaluate the efficacy of a biodegradable scleral plug containing ganciclovir (GCV) in a rabbit model of human cytomegalovirus (HCMV) retinitis. METHODS: To develop a rabbit model for HCMV retinitis, HCMV solution was injected once into the vitreous cavity of pigmented rabbits. The treated animals were divided into three groups: group A received no treatment, group B was treated once with GCV solution, and group C was treated with a scleral plug containing GCV. Rabbits in group B received an intravitreal injection of GCV solution 1 week after HCMV inoculation. In group C, the scleral plug containing GCV was implanted in the vitreous of the rabbits 1 week after HCMV inoculation. Ophthalmoscopically, vitreoretinal findings in each group were graded from 0+ to 4+ every week for 4 weeks after HCMV injection. RESULTS: Eyes of group A rabbits showed whitish retinal exudates and vitreous opacities 3 days after HCMV inoculation. These materials increased gradually until 3 weeks after HCMV inoculation. Scores for vitreoretinal lesions were significantly lower in eyes of group B rabbits compared with those of group A at 1 week after GCV injection (P < 0.05). However, vitreoretinal inflammation in eyes of group B rabbits increased again thereafter, and no significant difference in inflammation between groups A and B was found 2 weeks after GCV injection. In eyes of group C, scores for vitreoretinal lesions were significantly lower compared with those in both group A and group B at 3 weeks after HCMV inoculation (P < 0.01). CONCLUSIONS: The results demonstrated that sustained release of GCV into the vitreous cavity with biodegradable scleral plugs was effective for the treatment of experimentally induced HCMV retinitis in rabbits.  (+info)

Absorbable implants are medical devices that are designed to be placed inside the body during a surgical procedure, where they provide support, stabilization, or other functions, and then gradually break down and are absorbed by the body over time. These implants are typically made from materials such as polymers, proteins, or ceramics that have been engineered to degrade at a controlled rate, allowing them to be resorbed and eliminated from the body without the need for a second surgical procedure to remove them.

Absorbable implants are often used in orthopedic, dental, and plastic surgery applications, where they can help promote healing and support tissue regeneration. For example, absorbable screws or pins may be used to stabilize fractured bones during the healing process, after which they will gradually dissolve and be absorbed by the body. Similarly, absorbable membranes may be used in dental surgery to help guide the growth of new bone and gum tissue around an implant, and then be resorbed over time.

It's important to note that while absorbable implants offer several advantages over non-absorbable materials, such as reduced risk of infection and improved patient comfort, they may also have some limitations. For example, the mechanical properties of absorbable materials may not be as strong as those of non-absorbable materials, which could affect their performance in certain applications. Additionally, the degradation products of absorbable implants may cause local inflammation or other adverse reactions in some patients. As with any medical device, the use of absorbable implants should be carefully considered and discussed with a qualified healthcare professional.

Dental implants are artificial tooth roots that are surgically placed into the jawbone to replace missing or extracted teeth. They are typically made of titanium, a biocompatible material that can fuse with the bone over time in a process called osseointegration. Once the implant has integrated with the bone, a dental crown, bridge, or denture can be attached to it to restore function and aesthetics to the mouth.

Dental implants are a popular choice for tooth replacement because they offer several advantages over traditional options like dentures or bridges. They are more stable and comfortable, as they do not rely on adjacent teeth for support and do not slip or move around in the mouth. Additionally, dental implants can help to preserve jawbone density and prevent facial sagging that can occur when teeth are missing.

The process of getting dental implants typically involves several appointments with a dental specialist called a prosthodontist or an oral surgeon. During the first appointment, the implant is placed into the jawbone, and the gum tissue is stitched closed. Over the next few months, the implant will fuse with the bone. Once this process is complete, a second surgery may be necessary to expose the implant and attach an abutment, which connects the implant to the dental restoration. Finally, the crown, bridge, or denture is attached to the implant, providing a natural-looking and functional replacement for the missing tooth.

Prostheses: Artificial substitutes or replacements for missing body parts, such as limbs, eyes, or teeth. They are designed to restore the function, appearance, or mobility of the lost part. Prosthetic devices can be categorized into several types, including:

1. External prostheses: Devices that are attached to the outside of the body, like artificial arms, legs, hands, and feet. These may be further classified into:
a. Cosmetic or aesthetic prostheses: Primarily designed to improve the appearance of the affected area.
b. Functional prostheses: Designed to help restore the functionality and mobility of the lost limb.
2. Internal prostheses: Implanted artificial parts that replace missing internal organs, bones, or tissues, such as heart valves, hip joints, or intraocular lenses.

Implants: Medical devices or substances that are intentionally placed inside the body to replace or support a missing or damaged biological structure, deliver medication, monitor physiological functions, or enhance bodily functions. Examples of implants include:

1. Orthopedic implants: Devices used to replace or reinforce damaged bones, joints, or cartilage, such as knee or hip replacements.
2. Cardiovascular implants: Devices that help support or regulate heart function, like pacemakers, defibrillators, and artificial heart valves.
3. Dental implants: Artificial tooth roots that are placed into the jawbone to support dental prostheses, such as crowns, bridges, or dentures.
4. Neurological implants: Devices used to stimulate nerves, brain structures, or spinal cord tissues to treat various neurological conditions, like deep brain stimulators for Parkinson's disease or cochlear implants for hearing loss.
5. Ophthalmic implants: Artificial lenses that are placed inside the eye to replace a damaged or removed natural lens, such as intraocular lenses used in cataract surgery.

A drug implant is a medical device that is specially designed to provide controlled release of a medication into the body over an extended period of time. Drug implants can be placed under the skin or in various body cavities, depending on the specific medical condition being treated. They are often used when other methods of administering medication, such as oral pills or injections, are not effective or practical.

Drug implants come in various forms, including rods, pellets, and small capsules. The medication is contained within the device and is released slowly over time, either through diffusion or erosion of the implant material. This allows for a steady concentration of the drug to be maintained in the body, which can help to improve treatment outcomes and reduce side effects.

Some common examples of drug implants include:

1. Hormonal implants: These are small rods that are inserted under the skin of the upper arm and release hormones such as progestin or estrogen over a period of several years. They are often used for birth control or to treat conditions such as endometriosis or uterine fibroids.
2. Intraocular implants: These are small devices that are placed in the eye during surgery to release medication directly into the eye. They are often used to treat conditions such as age-related macular degeneration or diabetic retinopathy.
3. Bone cement implants: These are specially formulated cements that contain antibiotics and are used to fill bone defects or joint spaces during surgery. The antibiotics are released slowly over time, helping to prevent infection.
4. Implantable pumps: These are small devices that are placed under the skin and deliver medication directly into a specific body cavity, such as the spinal cord or the peritoneal cavity. They are often used to treat chronic pain or cancer.

Overall, drug implants offer several advantages over other methods of administering medication, including improved compliance, reduced side effects, and more consistent drug levels in the body. However, they may also have some disadvantages, such as the need for surgical placement and the potential for infection or other complications. As with any medical treatment, it is important to discuss the risks and benefits of drug implants with a healthcare provider.

Breast implants are medical devices that are inserted into the breast to enhance their size, shape, or fullness. They can also be used for breast reconstruction after a mastectomy or other medical treatments. Breast implants typically consist of a silicone shell filled with either saline (sterile saltwater) or silicone gel.

There are two main types of breast implants:

1. Saline-filled implants: These implants have a silicone outer shell that is filled with sterile saline solution after the implant has been inserted into the breast. This allows for some adjustment in the size and shape of the implant after surgery.
2. Silicone gel-filled implants: These implants have a silicone outer shell that is pre-filled with a cohesive silicone gel. The gel is designed to feel more like natural breast tissue than saline implants.

Breast implants come in various sizes, shapes, and textures, and the choice of implant will depend on several factors, including the patient's body type, desired outcome, and personal preference. It is important for patients considering breast implants to discuss their options with a qualified plastic surgeon who can help them make an informed decision based on their individual needs and goals.

Experimental implants refer to medical devices that are not yet approved by regulatory authorities for general use in medical practice. These are typically being tested in clinical trials to evaluate their safety and efficacy. The purpose of experimental implants is to determine whether they can be used as a viable treatment option for various medical conditions. They may include, but are not limited to, devices such as artificial joints, heart valves, or spinal cord stimulators that are still in the developmental or testing stage. Participation in clinical trials involving experimental implants is voluntary and usually requires informed consent from the patient.

Endosseous dental implantation is a medical procedure that involves the placement of an artificial tooth root (dental implant) directly into the jawbone. The term "endosseous" refers to the surgical placement of the implant within the bone (endo- meaning "within" and -osseous meaning "bony"). This type of dental implant is the most common and widely used method for replacing missing teeth.

During the procedure, a small incision is made in the gum tissue to expose the jawbone, and a hole is drilled into the bone to receive the implant. The implant is then carefully positioned and secured within the bone. Once the implant has integrated with the bone (a process that can take several months), a dental crown or bridge is attached to the implant to restore function and aesthetics to the mouth.

Endosseous dental implantation is a safe and effective procedure that has a high success rate, making it an excellent option for patients who are missing one or more teeth due to injury, decay, or other causes.

Orbital implants are medical devices used in the field of ophthalmology, specifically for orbital fracture repair and enucleation or evisceration procedures. They serve as a replacement for the natural eye structure (the eyeball) when it is removed due to various reasons such as severe trauma, tumors, or painful blind eyes.

Orbital implants are typically made of biocompatible materials like porous polyethylene, hydroxyapatite, or glass. These materials allow for the growth of fibrovascular tissue into the pores, which helps to integrate the implant with the surrounding tissues and minimize movement. The size of the implant is chosen based on the individual patient's needs and may vary from 16mm to 24mm in diameter.

The primary function of orbital implants is to restore the volume and shape of the eye socket, maintain proper eyelid position and function, and provide a foundation for the attachment of an ocular prosthesis (artificial eye) that can be worn over the implant to give a more natural appearance.

A dental implant is a surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, facial prosthesis or to act as an orthodontic anchor.

A single-tooth dental implant specifically refers to the replacement of a single missing tooth. The process typically involves three stages:

1. Placement: A titanium screw is placed into the jawbone where the missing tooth once was, acting as a root for the new tooth.
2. Osseointegration: Over several months, the jawbone grows around and fuses with the implant, creating a strong and stable foundation for the replacement tooth.
3. Restoration: A custom-made crown is attached to the implant, restoring the natural appearance and function of the missing tooth.

Single-tooth dental implants are a popular choice because they look, feel, and function like natural teeth, and they do not require the alteration of adjacent teeth, as is necessary with traditional bridgework.

Titanium is not a medical term, but rather a chemical element (symbol Ti, atomic number 22) that is widely used in the medical field due to its unique properties. Medically, it is often referred to as a biocompatible material used in various medical applications such as:

1. Orthopedic implants: Titanium and its alloys are used for making joint replacements (hips, knees, shoulders), bone plates, screws, and rods due to their high strength-to-weight ratio, excellent corrosion resistance, and biocompatibility.
2. Dental implants: Titanium is also commonly used in dental applications like implants, crowns, and bridges because of its ability to osseointegrate, or fuse directly with bone tissue, providing a stable foundation for replacement teeth.
3. Cardiovascular devices: Titanium alloys are used in the construction of heart valves, pacemakers, and other cardiovascular implants due to their non-magnetic properties, which prevent interference with magnetic resonance imaging (MRI) scans.
4. Medical instruments: Due to its resistance to corrosion and high strength, titanium is used in the manufacturing of various medical instruments such as surgical tools, needles, and catheters.

In summary, Titanium is a chemical element with unique properties that make it an ideal material for various medical applications, including orthopedic and dental implants, cardiovascular devices, and medical instruments.

A dental prosthesis that is supported by dental implants is an artificial replacement for one or more missing teeth. It is a type of dental restoration that is anchored to the jawbone using one or more titanium implant posts, which are surgically placed into the bone. The prosthesis is then attached to the implants, providing a stable and secure fit that closely mimics the function and appearance of natural teeth.

There are several types of implant-supported dental prostheses, including crowns, bridges, and dentures. A single crown may be used to replace a single missing tooth, while a bridge or denture can be used to replace multiple missing teeth. The specific type of prosthesis used will depend on the number and location of the missing teeth, as well as the patient's individual needs and preferences.

Implant-supported dental prostheses offer several advantages over traditional removable dentures, including improved stability, comfort, and functionality. They also help to preserve jawbone density and prevent facial sagging that can occur when teeth are missing. However, they do require a surgical procedure to place the implants, and may not be suitable for all patients due to factors such as bone density or overall health status.

Cochlear implantation is a surgical procedure in which a device called a cochlear implant is inserted into the inner ear (cochlea) of a person with severe to profound hearing loss. The implant consists of an external component, which includes a microphone, processor, and transmitter, and an internal component, which includes a receiver and electrode array.

The microphone picks up sounds from the environment and sends them to the processor, which analyzes and converts the sounds into electrical signals. These signals are then transmitted to the receiver, which stimulates the electrode array in the cochlea. The electrodes directly stimulate the auditory nerve fibers, bypassing the damaged hair cells in the inner ear that are responsible for normal hearing.

The brain interprets these electrical signals as sound, allowing the person to perceive and understand speech and other sounds. Cochlear implantation is typically recommended for people who do not benefit from traditional hearing aids and can significantly improve communication, quality of life, and social integration for those with severe to profound hearing loss.

A dental prosthesis is a device that replaces missing teeth or parts of teeth and restores their function and appearance. The design of a dental prosthesis refers to the plan and specifications used to create it, including the materials, shape, size, and arrangement of the artificial teeth and any supporting structures.

The design of a dental prosthesis is typically based on a variety of factors, including:

* The number and location of missing teeth
* The condition of the remaining teeth and gums
* The patient's bite and jaw alignment
* The patient's aesthetic preferences
* The patient's ability to chew and speak properly

There are several types of dental prostheses, including:

* Dentures: A removable appliance that replaces all or most of the upper or lower teeth.
* Fixed partial denture (FPD): Also known as a bridge, this is a fixed (non-removable) appliance that replaces one or more missing teeth by attaching artificial teeth to the remaining natural teeth on either side of the gap.
* Removable partial denture (RPD): A removable appliance that replaces some but not all of the upper or lower teeth.
* Implant-supported prosthesis: An artificial tooth or set of teeth that is supported by dental implants, which are surgically placed in the jawbone.

The design of a dental prosthesis must be carefully planned and executed to ensure a good fit, proper function, and natural appearance. It may involve several appointments with a dentist or dental specialist, such as a prosthodontist, to take impressions, make measurements, and try in the finished prosthesis.

Immediate dental implant loading is a dental procedure where a dental implant is placed and a restoration (such as a crown, bridge, or denture) is attached to it during the same appointment or immediately after the implant surgery. Traditionally, dental implants were allowed to heal and integrate with the jawbone for several months before loading (placing the restoration), but recent advances in implant technology and surgical techniques have made immediate loading a viable option in certain cases.

The success of immediate dental implant loading depends on various factors such as the patient's oral health, the quality and quantity of bone, the type and location of the implant, and the expertise of the dental professional. Immediate loading can offer several benefits, including reduced treatment time, fewer surgical procedures, and improved aesthetics and function. However, it is not always suitable for every patient or situation, and a thorough evaluation is necessary to determine if immediate loading is the best option.

Deafness is a hearing loss that is so severe that it results in significant difficulty in understanding or comprehending speech, even when using hearing aids. It can be congenital (present at birth) or acquired later in life due to various causes such as disease, injury, infection, exposure to loud noises, or aging. Deafness can range from mild to profound and may affect one ear (unilateral) or both ears (bilateral). In some cases, deafness may be accompanied by tinnitus, which is the perception of ringing or other sounds in the ears.

Deaf individuals often use American Sign Language (ASL) or other forms of sign language to communicate. Some people with less severe hearing loss may benefit from hearing aids, cochlear implants, or other assistive listening devices. Deafness can have significant social, educational, and vocational implications, and early intervention and appropriate support services are critical for optimal development and outcomes.

A dental abutment is a component of a dental implant restoration that connects the implant to the replacement tooth or teeth. It serves as a support structure and is attached to the implant, which is surgically placed in the jawbone. The abutment provides a stable foundation for the placement of a crown, bridge, or denture, depending on the patient's individual needs.

Dental abutments can be made from various materials such as titanium, zirconia, or other biocompatible materials. They come in different shapes and sizes to accommodate the specific requirements of each implant case. The selection of an appropriate dental abutment is crucial for ensuring a successful and long-lasting dental implant restoration.

Prosthesis design is a specialized field in medical device technology that involves creating and developing artificial substitutes to replace a missing body part, such as a limb, tooth, eye, or internal organ. The design process typically includes several stages: assessment of the patient's needs, selection of appropriate materials, creation of a prototype, testing and refinement, and final fabrication and fitting of the prosthesis.

The goal of prosthesis design is to create a device that functions as closely as possible to the natural body part it replaces, while also being comfortable, durable, and aesthetically pleasing for the patient. The design process may involve collaboration between medical professionals, engineers, and designers, and may take into account factors such as the patient's age, lifestyle, occupation, and overall health.

Prosthesis design can be highly complex, particularly for advanced devices such as robotic limbs or implantable organs. These devices often require sophisticated sensors, actuators, and control systems to mimic the natural functions of the body part they replace. As a result, prosthesis design is an active area of research and development in the medical field, with ongoing efforts to improve the functionality, comfort, and affordability of these devices for patients.

A dental prosthesis known as an "overlay denture" is a type of removable restoration that covers and restores only the occlusal (biting) surfaces of the natural teeth, while leaving the remaining tooth structure and surrounding soft tissues intact. This type of denture is typically used when there are still sufficient healthy tooth structures present to provide support and stability for the prosthesis.

Overlay dentures can be made from various materials such as acrylic resin or metal alloys, and they can be fabricated to fit over the natural teeth with precision, ensuring optimal comfort and functionality. These dentures are designed to improve the patient's ability to chew and speak properly, while also enhancing their smile and overall oral esthetics.

It is important to note that proper dental hygiene and regular check-ups with a dental professional are essential for maintaining good oral health and ensuring the longevity of an overlay denture.

Prosthesis implantation is a surgical procedure where an artificial device or component, known as a prosthesis, is placed inside the body to replace a missing or damaged body part. The prosthesis can be made from various materials such as metal, plastic, or ceramic and is designed to perform the same function as the original body part.

The implantation procedure involves making an incision in the skin to create a pocket where the prosthesis will be placed. The prosthesis is then carefully positioned and secured in place using screws, cement, or other fixation methods. In some cases, tissue from the patient's own body may be used to help anchor the prosthesis.

Once the prosthesis is in place, the incision is closed with sutures or staples, and the area is bandaged. The patient will typically need to undergo rehabilitation and physical therapy to learn how to use the new prosthesis and regain mobility and strength.

Prosthesis implantation is commonly performed for a variety of reasons, including joint replacement due to arthritis or injury, dental implants to replace missing teeth, and breast reconstruction after mastectomy. The specific procedure and recovery time will depend on the type and location of the prosthesis being implanted.

Prosthesis failure is a term used to describe a situation where a prosthetic device, such as an artificial joint or limb, has stopped functioning or failed to meet its intended purpose. This can be due to various reasons, including mechanical failure, infection, loosening of the device, or a reaction to the materials used in the prosthesis.

Mechanical failure can occur due to wear and tear, manufacturing defects, or improper use of the prosthetic device. Infection can also lead to prosthesis failure, particularly in cases where the prosthesis is implanted inside the body. The immune system may react to the presence of the foreign material, leading to inflammation and infection.

Loosening of the prosthesis can also cause it to fail over time, as the device becomes less stable and eventually stops working properly. Additionally, some people may have a reaction to the materials used in the prosthesis, leading to tissue damage or other complications that can result in prosthesis failure.

In general, prosthesis failure can lead to decreased mobility, pain, and the need for additional surgeries or treatments to correct the problem. It is important for individuals with prosthetic devices to follow their healthcare provider's instructions carefully to minimize the risk of prosthesis failure and ensure that the device continues to function properly over time.

Dental prosthesis retention refers to the means by which a dental prosthesis, such as a denture, is held in place in the mouth. The retention can be achieved through several methods, including:

1. Suction: This is the most common method of retention for lower dentures, where the shape and fit of the denture base create suction against the gums to hold it in place.
2. Mechanical retention: This involves the use of mechanical components such as clasps or attachments that hook onto remaining natural teeth or dental implants to hold the prosthesis in place.
3. Adhesive retention: Dental adhesives can be used to help secure the denture to the gums, providing additional retention and stability.
4. Implant retention: Dental implants can be used to provide a more secure and stable retention of the dental prosthesis. The implant is surgically placed in the jawbone and acts as an anchor for the prosthesis.

Proper retention of a dental prosthesis is essential for optimal function, comfort, and speech. A well-retained prosthesis can help prevent sore spots, improve chewing efficiency, and enhance overall quality of life.

A Molteno implant refers to a type of glaucoma drainage device used in ophthalmology to lower intraocular pressure (IOP) in patients with uncontrolled glaucoma. The device consists of a small plastic plate with a silicone tube that is implanted into the eye during a surgical procedure.

The tube creates a passage for the aqueous humor, the fluid inside the eye, to flow out of the eye and into a reservoir created by the plate, which is positioned under the conjunctiva (the clear membrane covering the white part of the eye). The fluid is then absorbed by the body, reducing the IOP within the eye.

The Molteno implant is typically used in cases where other glaucoma treatments have failed, and it provides a long-term solution for managing IOP and preventing further damage to the optic nerve and visual field. It is named after Anthony Molteno, who developed the device in the 1960s.

An artificial eye, also known as a prosthetic eye, is a type of medical device that is used to replace a natural eye that has been removed or is not functional due to injury, disease, or congenital abnormalities. It is typically made of acrylic or glass and is custom-made to match the size, shape, and color of the patient's other eye as closely as possible.

The artificial eye is designed to fit over the eye socket and rest on the eyelids, allowing the person to have a more natural appearance and improve their ability to blink and close their eye. It does not restore vision, but it can help protect the eye socket and improve the patient's self-esteem and quality of life.

The process of fitting an artificial eye typically involves several appointments with an ocularist, who is a healthcare professional trained in the measurement, design, and fabrication of prosthetic eyes. The ocularist will take impressions of the eye socket, create a model, and then use that model to make the artificial eye. Once the artificial eye is made, the ocularist will fit it and make any necessary adjustments to ensure that it is comfortable and looks natural.

A foreign-body reaction is an immune response that occurs when a non-native substance, or "foreign body," is introduced into the human body. This can include things like splinters, surgical implants, or even injected medications. The immune system recognizes these substances as foreign and mounts a response to try to eliminate them.

The initial response to a foreign body is often an acute inflammatory reaction, characterized by the release of chemical mediators that cause vasodilation, increased blood flow, and the migration of white blood cells to the site. This can result in symptoms such as redness, swelling, warmth, and pain.

If the foreign body is not eliminated, a chronic inflammatory response may develop, which can lead to the formation of granulation tissue, fibrosis, and encapsulation of the foreign body. In some cases, this reaction can cause significant tissue damage or impede proper healing.

It's worth noting that not all foreign bodies necessarily elicit a strong immune response. The nature and size of the foreign body, as well as its location in the body, can all influence the severity of the reaction.

Silicone gels are synthetic substances that are made from the polymerization of silicone, which is a combination of silicon, oxygen, and other elements such as carbon and hydrogen. In medical terms, silicone gels are often used in the manufacture of breast implants, where they are used to fill the implant shells. The gel has a soft, flexible texture that feels similar to natural breast tissue.

Silicone gels can also be used in other medical devices such as contact lenses, catheters, and wound dressings. They have a number of properties that make them useful for medical applications, including their ability to maintain their shape and flexibility, their resistance to heat and chemicals, and their low toxicity.

It is important to note that while silicone gels are generally considered safe for use in medical devices, there have been concerns raised about the potential health effects of breast implants filled with silicone gel. Some studies have suggested a link between silicone breast implants and certain health problems, such as connective tissue diseases and autoimmune disorders, but the evidence is not conclusive and more research is needed to fully understand the risks.

Trenbolone Acetate is an esterified form of the synthetic steroid hormone Trenbolone. It is a potent anabolic and androgenic steroid, which is used in veterinary medicine for promoting muscle growth and appetite stimulation in cattle. In human medicine, it is not approved for use but is sometimes misused for its anabolic effects, such as increasing muscle mass, strength, and reducing body fat. It is important to note that the use of Trenbolone Acetate in humans is considered off-label and can lead to serious health consequences, including liver toxicity, cardiovascular issues, and hormonal imbalances.

Edentulous partially refers to a condition where some teeth are missing in the jaw but not all. In other words, it is a state of having fewer teeth than normal for that particular dental arch. A dental arch can be either the upper or lower jaw.

In medical terms, "edentulous" means lacking teeth. So, when we say "jaw, edentulous, partially," it indicates a jaw that has some missing teeth. This condition is different from being completely edentulous, which refers to having no teeth at all in the dental arch.

Being edentulous or partially edentulous can impact an individual's ability to eat, speak, and affect their overall quality of life. Dental professionals often recommend various treatment options, such as dentures, bridges, or implants, to restore functionality and aesthetics for those who are partially edentulous.

Silicones are not a medical term, but they are commonly used in the medical field, particularly in medical devices and healthcare products. Silicones are synthetic polymers made up of repeating units of siloxane, which is a chain of alternating silicon and oxygen atoms. They can exist in various forms such as oils, gels, rubbers, and resins.

In the medical context, silicones are often used for their unique properties, including:

1. Biocompatibility - Silicones have a low risk of causing an adverse reaction when they come into contact with living tissue.
2. Inertness - They do not react chemically with other substances, making them suitable for use in medical devices that need to remain stable over time.
3. Temperature resistance - Silicones can maintain their flexibility and elasticity even under extreme temperature conditions.
4. Gas permeability - Some silicone materials allow gases like oxygen and water vapor to pass through, which is useful in applications where maintaining a moist environment is essential.
5. Durability - Silicones have excellent resistance to aging, weathering, and environmental factors, ensuring long-lasting performance.

Examples of medical applications for silicones include:

1. Breast implants
2. Contact lenses
3. Catheters
4. Artificial joints and tendons
5. Bandages and wound dressings
6. Drug delivery systems
7. Medical adhesives
8. Infant care products (nipples, pacifiers)

Biocompatible materials are non-toxic and non-reacting substances that can be used in medical devices, tissue engineering, and drug delivery systems without causing harm or adverse reactions to living tissues or organs. These materials are designed to mimic the properties of natural tissues and are able to integrate with biological systems without being rejected by the body's immune system.

Biocompatible materials can be made from a variety of substances, including metals, ceramics, polymers, and composites. The specific properties of these materials, such as their mechanical strength, flexibility, and biodegradability, are carefully selected to meet the requirements of their intended medical application.

Examples of biocompatible materials include titanium used in dental implants and joint replacements, polyethylene used in artificial hips, and hydrogels used in contact lenses and drug delivery systems. The use of biocompatible materials has revolutionized modern medicine by enabling the development of advanced medical technologies that can improve patient outcomes and quality of life.

Speech perception is the process by which the brain interprets and understands spoken language. It involves recognizing and discriminating speech sounds (phonemes), organizing them into words, and attaching meaning to those words in order to comprehend spoken language. This process requires the integration of auditory information with prior knowledge and context. Factors such as hearing ability, cognitive function, and language experience can all impact speech perception.

Dental restoration failure refers to the breakdown or loss of functionality of a dental restoration, which is a procedure performed to restore the function, integrity, and morphology of a tooth that has been damaged due to decay, trauma, or wear. The restoration can include fillings, crowns, veneers, bridges, and implants. Failure of dental restorations can occur due to various reasons such as recurrent decay, fracture, poor fit, or material failure, leading to further damage or loss of the tooth.

Capsular contracture is a complication that can occur after a breast augmentation or reconstruction surgery, where the body forms a capsule (a normal biological response) around the foreign material, such as a breast implant. However, in capsular contracture, this capsule tightens and squeezes the implant, causing the breast to feel hard, painful, and sometimes misshapen. It is classified into four grades (I-IV) based on the severity of symptoms, with grade IV indicating the most severe form, characterized by significant pain, implant palpability, and distortion.

Dura Mater: The tough, outer membrane that covers the brain and spinal cord.

Hydroxyapatite: A naturally occurring mineral form of calcium apatite, also known as dahllite, with the formula Ca5(PO4)3(OH), is the primary mineral component of biological apatites found in bones and teeth.

Therefore, "Durapatite" isn't a recognized medical term, but it seems like it might be a combination of "dura mater" and "hydroxyapatite." If you meant to ask about a material used in medical or dental applications that combines properties of both dura mater and hydroxyapatite, please provide more context.

Peri-implantitis is a medical term used to describe the inflammatory condition that affects the soft and hard tissues surrounding dental implants, leading to their progressive loss. It's characterized by an infection that causes inflammation in the gums and potentially in the bone around the implant.

The primary cause of peri-implantitis is bacterial biofilm accumulation, similar to what leads to periodontal disease around natural teeth. Other factors contributing to its development can include poor oral hygiene, smoking, diabetes, and genetic predisposition.

Symptoms may include redness, swelling, bleeding, and pus formation in the gums around the implant, as well as pain, mobility, or even loss of the affected dental implant if left untreated. Treatment options vary depending on the severity of the condition but often involve mechanical debridement, antibiotic therapy, and possible surgical intervention to regenerate lost tissue.

The correction of hearing impairment refers to the various methods and technologies used to improve or restore hearing function in individuals with hearing loss. This can include the use of hearing aids, cochlear implants, and other assistive listening devices. Additionally, speech therapy and auditory training may also be used to help individuals with hearing impairment better understand and communicate with others. In some cases, surgical procedures may also be performed to correct physical abnormalities in the ear or improve nerve function. The goal of correction of hearing impairment is to help individuals with hearing loss better interact with their environment and improve their overall quality of life.

I'm happy to help! However, I must clarify that "materials testing" is not a medical term per se. It is a term used in various fields, including engineering and materials science, to describe the process of subjecting materials to different tests to evaluate their properties and performance under various conditions.

In the context of medical devices or implants, materials testing may refer to the evaluation of the physical and mechanical properties of materials used in their construction. These tests can include assessments of strength, durability, biocompatibility, and other factors that are critical to ensuring the safety and efficacy of medical devices.

Medical device manufacturers must comply with regulatory standards for materials testing to ensure that their products meet specific requirements for performance, safety, and quality. These standards may vary depending on the type of device, its intended use, and the country or region in which it will be marketed and sold.

A hip prosthesis, also known as a total hip replacement, is a surgical implant designed to replace the damaged or diseased components of the human hip joint. The procedure involves replacing the femoral head (the ball at the top of the thigh bone) and the acetabulum (the socket in the pelvis) with artificial parts, typically made from materials such as metal, ceramic, or plastic.

The goal of a hip prosthesis is to relieve pain, improve joint mobility, and restore function, allowing patients to return to their normal activities and enjoy an improved quality of life. The procedure is most commonly performed in individuals with advanced osteoarthritis, rheumatoid arthritis, or other degenerative conditions that have caused significant damage to the hip joint.

There are several different types of hip prostheses available, each with its own unique design and set of benefits and risks. The choice of prosthesis will depend on a variety of factors, including the patient's age, activity level, overall health, and specific medical needs. In general, however, all hip prostheses are designed to provide a durable, long-lasting solution for patients suffering from debilitating joint pain and stiffness.

A dental implant-abutment design refers to the specific configuration and components used to connect a dental implant, which serves as an artificial tooth root, to a dental restoration, such as a crown, bridge, or denture. The abutment is a connecting element that attaches to the implant and provides the foundation for the dental restoration.

There are various dental implant-abutment designs available, each with its unique advantages and disadvantages. Some common designs include:

1. External hexagon: This design features an external hexagonal connection between the implant and abutment. It is one of the earliest and most widely used designs but has largely been replaced by internal connection designs due to concerns about screw loosening and microbial leakage.
2. Internal hexagon: In this design, the hexagonal connection is located inside the implant, providing better stability and resistance to rotational forces compared to external hexagon designs.
3. Morse taper: This design uses a tapered connection between the implant and abutment, creating a tight, press-fit interface that resists micromovements and microbial leakage. It is known for its high stability and ease of use.
4. UCLA (University of California, Los Angeles) abutment: This design features a custom-milled abutment specifically designed to fit the individual implant platform. The UCLA abutment provides excellent esthetics and precision but requires additional laboratory fabrication time and costs.
5. Platform switching: This design involves using an abutment with a smaller diameter than the implant platform, creating a gap between the implant and abutment. This gap has been shown to reduce crestal bone loss and improve soft tissue esthetics around dental implants.
6. Cement-retained: In this design, the restoration is cemented onto the abutment using a dental cement. While it provides good esthetics and simplicity, there are concerns about excess cement causing peri-implant inflammation and bone loss.
7. Screw-retained: This design involves securing the restoration to the abutment with a screw. It offers easy retrievability and maintenance but may have compromised esthetics due to the presence of a screw access hole.

Each dental implant system has its unique advantages and disadvantages, and selecting the appropriate one depends on various factors such as the patient's anatomy, oral health status, and desired treatment outcomes. Dentists should consider these factors when choosing the most suitable implant system for their patients.

Alveolar ridge augmentation is a surgical procedure in dentistry that aims to reconstruct or enhance the volume and shape of the alveolar ridge, which is the bony ridge that supports the dental arch and holds the teeth in place. This procedure is often performed in preparation for dental implant placement when the jawbone lacks sufficient width, height, or density to support the implant securely.

The alveolar ridge augmentation process typically involves several steps:

1. Assessment: The dentist or oral surgeon evaluates the patient's oral condition and takes dental images (such as X-rays or CBCT scans) to determine the extent of bone loss and plan the surgical procedure accordingly.
2. Grafting material selection: Depending on the specific needs of the patient, various grafting materials can be used, including autografts (patient's own bone), allografts (bone from a human donor), xenografts (bone from an animal source), or synthetic materials.
3. Surgical procedure: The oral surgeon exposes the deficient area of the alveolar ridge and carefully places the grafting material, ensuring proper contour and stabilization. In some cases, a barrier membrane may be used to protect the graft and promote healing.
4. Healing period: After the surgery, a healing period is required for the grafted bone to integrate with the existing jawbone. This process can take several months, depending on factors such as the size of the graft and the patient's overall health.
5. Implant placement: Once the alveolar ridge augmentation has healed and sufficient bone volume has been achieved, dental implants can be placed to support replacement teeth, such as crowns, bridges, or dentures.

Alveolar ridge augmentation is a valuable technique for restoring jawbone structure and function, enabling patients with significant bone loss to receive dental implants and enjoy improved oral health and aesthetics.

Surface properties in the context of medical science refer to the characteristics and features of the outermost layer or surface of a biological material or structure, such as cells, tissues, organs, or medical devices. These properties can include physical attributes like roughness, smoothness, hydrophobicity or hydrophilicity, and electrical conductivity, as well as chemical properties like charge, reactivity, and composition.

In the field of biomaterials science, understanding surface properties is crucial for designing medical implants, devices, and drug delivery systems that can interact safely and effectively with biological tissues and fluids. Surface modifications, such as coatings or chemical treatments, can be used to alter surface properties and enhance biocompatibility, improve lubricity, reduce fouling, or promote specific cellular responses like adhesion, proliferation, or differentiation.

Similarly, in the field of cell biology, understanding surface properties is essential for studying cell-cell interactions, cell signaling, and cell behavior. Cells can sense and respond to changes in their environment, including variations in surface properties, which can influence cell shape, motility, and function. Therefore, characterizing and manipulating surface properties can provide valuable insights into the mechanisms of cellular processes and offer new strategies for developing therapies and treatments for various diseases.

Breast implantation is a surgical procedure where breast implants are placed in the body to enhance the size, shape, and/or symmetry of the breasts. The implants can be filled with either saline solution or silicone gel and are inserted through incisions made in various locations on the breast or around the nipple. The goal of the procedure is to improve the appearance of the breasts and may be performed for cosmetic reasons, as part of a breast reconstruction after a mastectomy, or to correct congenital deformities.

The procedure typically involves making an incision in one of several locations:

1. Inframammary fold: This is the most common approach and involves making an incision in the crease beneath the breast.
2. Periareolar: This approach involves making an incision around the areola (the dark-colored skin surrounding the nipple).
3. Transaxillary: This approach involves making an incision in the armpit and creating a tunnel to the breast pocket.
4. Transumbilical: This is the least common approach and involves making an incision in the belly button and creating a tunnel to the breast pocket.

Once the implant is placed, the incisions are closed with sutures or surgical tape. The procedure typically takes 1-2 hours and may be performed as an outpatient procedure or require an overnight hospital stay. Recovery time varies but typically involves wearing a compression garment for several weeks to support the breasts and minimize swelling.

It is important to note that breast implantation carries certain risks, including infection, bleeding, scarring, capsular contracture (scar tissue formation around the implant), implant rupture or deflation, and changes in nipple sensation. Regular follow-up with a healthcare provider is necessary to monitor for any potential complications.

A joint prosthesis, also known as an artificial joint or a replacement joint, is a surgical implant used to replace all or part of a damaged or diseased joint. The most common types of joint prostheses are total hip replacements and total knee replacements. These prostheses typically consist of a combination of metal, plastic, and ceramic components that are designed to replicate the movement and function of a natural joint.

Joint prostheses are usually recommended for patients who have severe joint pain or mobility issues that cannot be adequately managed with other treatments such as physical therapy, medication, or lifestyle changes. The goal of joint replacement surgery is to relieve pain, improve joint function, and enhance the patient's quality of life.

Joint prostheses are typically made from materials such as titanium, cobalt-chrome alloys, stainless steel, polyethylene plastic, and ceramics. The choice of material depends on a variety of factors, including the patient's age, activity level, weight, and overall health.

While joint replacement surgery is generally safe and effective, there are risks associated with any surgical procedure, including infection, blood clots, implant loosening or failure, and nerve damage. Patients who undergo joint replacement surgery typically require several weeks of rehabilitation and physical therapy to regain strength and mobility in the affected joint.
