Elastic activator for treatment of open bite. (1/57)

This article presents a modified activator for treatment of open bite cases. The intermaxillary acrylic of the lateral occlusal zones is replaced by elastic rubber tubes. By stimulating orthopaedic gymnastics (chewing gum effect), the elastic activator intrudes upper and lower posterior teeth. A noticeable counterclockwise rotation of the mandible was accomplished by a decrease of the gonial angle. Besides the simple fabrication of the device and uncomplicated replacement of the elastic rubber tubes, treatment can be started even in mixed dentition when affixing plates may be difficult.  (+info)

Class II combination therapy (distal jet and Jasper Jumpers): a case report. (2/57)

Class II combination therapy is a method that combines orthodontic and orthopedic mechanics in a single stage of treatment. Molar distalization is followed by fixed functional mechanics to reduce the dependence upon patient compliance while seeking more predictable completion of Class II correction.  (+info)

Class II correction-reducing patient compliance: a review of the available techniques. (3/57)

The correction of Class II malocclusions has been hampered by the use of appliances which require the patient to co-operate with headgear, elastics, or the wearing of a removable appliance. 'Non-compliance therapy' involves the use of appliances which minimize the need for such co-operation and attempt to maximize the predictability of results. This article reviews and describes the types of appliances used, and their mode of action-based on the current available research.  (+info)

The temporomandibular joint and the disc-condyle relationship after functional orthopaedic treatment: a magnetic resonance imaging study. (4/57)

Causative correction of Class II skeletal malocclusions may be achieved through bite jumping by various means. Numerous animal experiments have yielded evidence of remodelled temporomandibular structures after mandibular protrusion. However, the mode and extent of structural and/or topographic changes of the disc-condyle relationship after functional orthopaedic treatment is still unresolved. A problem exists in defining the physiological position of the condyles and disc-condyle relationship, which is tentatively determined by various methods particularly in magnetic resonance tomographic studies. Despite the high resolution provided, the results have to be interpreted with caution, as osseous resorption and apposition cannot be assessed by visual evidence. This investigation examined the impact on the temporomandibular joints (TMJ), i.e. the condylar shape and position, and the disc-condyle relationship, of the bionator plus extra-oral traction in combination with vertical elastics. The underlying reactions were studied by means of magnetic resonance images (MRI) obtained from n = 15 successfully treated patients (mean age 11.6 years).  (+info)

A comparative study of two mandibular advancement appliances for the treatment of obstructive sleep apnoea. (5/57)

Mandibular advancement appliances (MAAs) are accepted as a treatment option for snoring and mild obstructive sleep disorders. In the present clinical study two differently designed devices were examined for their effectiveness in treating obstructive sleep apnoea (OSA). The study was based on an assessment of 26 patients with a polysomnographic diagnosis of mild OSA [22 men, four women; mean body mass index 27.3 kg/m2 (SD 3.1); mean age 56.8 years (SD 5.2); mean respiratory disturbance index (RDI): 16.0 events/hour (SD 4.4)]. After insertion of the first MAA and a 6-8-week habituation period, a cardio-respiratory home-sleep study was carried out. Following a 2-3-week period with no treatment, the second appliance was inserted. The sequence of the devices was randomized. Once the patients had become accustomed to the second appliance, another somnographic registration was carried out. Daytime sleepiness, snoring, and sleep quality were assessed subjectively on a visual analogue scale. The results showed that a statistically significant improvement in the respiratory parameters was achieved with both appliances (P < 0.01). However, the activator [RDI: 5.5 events/hour, SD 3.3; apnoea index (AI): 3.4 events/hour, SD 2.1] was significantly more effective (P < 0.01) than the Silencor (RDI, 7.3 events/hour, SD 5.3; AI: 5.8 events/hour, SD 3.2). No difference was recorded in the subjective assessment of the therapeutic effects. Both appliances reduced daytime sleepiness and snoring and improved sleep quality, and both influenced the treatment outcome.  (+info)

Effective temporomandibular joint growth and chin position changes: Activator versus Herbst treatment. A cephalometric roentgenographic study. (6/57)

In 138 successfully treated Class II division 1 patients (40 Activator and 98 Herbst) effective temporomandibular joint (TMJ) growth changes (a summation of condylar remodelling, glenoid fossa remodelling, and condylar position changes within the fossa), and their influence on the position of the chin and the rotation of the mandible were analysed retrospectively. Lateral head films in habitual occlusion from before and after an average treatment period of 2.6 years for the Activator patients and 0.6 years for the Herbst patients were evaluated. Two different treatment changes were assessed: (1) overall growth changes and (2) treatment effects (overall growth changes minus age-related normal growth values: Bolton Standards). The comparison between the Activator and the Herbst group revealed larger effective TMJ and chin changes during Activator therapy due to the longer observation period (2.6 years versus 0.6 years). The treatment effects showed marked group differences for both the amount and direction of effective TMJ changes. The changes were vertical and slightly anterior in the Activator group, and predominantly posterior in the Herbst group. Concerning the chin changes, the treatment effects for the Herbst group exceeded those for the Activator group in both directions, caudally and anteriorly. The Activator group showed an anterior rotation and the Herbst group a slight posterior rotation of the mandible. The present investigation revealed that the effective TMJ and chin changes were increased by both Activator and Herbst treatment. However, the Herbst appliance renders more favourable sagittally orientated treatment effects in a much shorter period of time compared with the Activator.  (+info)

The effects of activator treatment on the craniofacial structures of Class II division 1 patients. (7/57)

The aim of the present study was to clarify the skeletal treatment effects induced by activator treatment. Fifty actively growing patients with Class II division 1 malocclusions were treated with an activator appliance. A control group consisting of longitudinal growth data from 20 patients (untreated Class II division 1 malocclusions) was used to eliminate possible differences in growth pattern. Lateral cephalograms of each patient were taken at the start and end of treatment. Final cephalograms were taken after a mean of 16.4 (+/- 2.0) months activator treatment, compared with a mean of 14.2 (+/- 2.4) months for the control group. Each cephalogram was traced and digitized by the same individual. The mean and standard deviations for linear and angular cephalometric measurements were analysed statistically, and intra- and inter-group changes were evaluated by paired- and independent-sample t-tests. At the end of the study period, the overjet was decreased in all patients. Ramus height, corpus length, anterior and posterior face height all increased significantly (P < 0.05). In the treatment group, ANB angle decreased and the bite was opened. The activator appliance caused maxillary incisor lingual tipping and mandibular incisor labial tipping. The overjet was decreased as a result of the increased forward growth of the mandible and dentoalveolar changes. The results demonstrated that the activator appliance has a characteristic skeletal and dental effect on the developing craniofacial complex.  (+info)

Contemporary treatment of a crowded Class II division 1 case. (8/57)

A 12-year-old Caucasian male presented with a severe Class II division 1 incisor relationship on a mild Skeletal II base with an average maxillary-mandibular planes angle and average lower facial height. Crowding was severe in the upper arch and moderate in the lower arch. Treatment was commenced using Twin Block appliances, and followed by extractions in all four quadrants and fixed appliances. This case illustrates the versatility of the Twin Block appliance in the treatment of those cases exhibiting crowding.  (+info)

Activator appliances are a type of removable orthodontic device used to expand the arch of the teeth and make other adjustments to the bite. They are typically made of acrylic material and may include metal components such as screws or wires that can be adjusted to apply pressure to specific teeth or areas of the jaw.

The activator appliance works by using gentle forces to gradually move the teeth into their desired positions over time. It is often used in conjunction with other orthodontic treatments, such as braces or aligners, to help achieve optimal results. The appliance may be worn for several hours each day or overnight, depending on the specific treatment plan.

Activator appliances are typically custom-made for each patient based on a detailed evaluation of their oral structure and bite pattern. They can be used to treat a variety of orthodontic issues, including overbites, underbites, crossbites, and crowded teeth. Regular adjustments and follow-up appointments with an orthodontist are necessary to ensure that the appliance is working effectively and to make any necessary modifications to the treatment plan.

Orthodontic appliances are devices used in orthodontics, a branch of dentistry focused on the diagnosis, prevention, and treatment of dental and facial irregularities. These appliances can be fixed or removable and are used to align teeth, correct jaw relationships, or modify dental forces. They can include braces, aligners, palatal expanders, space maintainers, and headgear, among others. The specific type of appliance used depends on the individual patient's needs and the treatment plan developed by the orthodontist.

Orthodontic appliances, removable, are dental devices that can be removed and inserted by the patient as needed or directed. These appliances are designed to align and straighten teeth, correct bite issues, and improve the function and appearance of the teeth and jaws. They are typically made from materials such as plastic, metal, or acrylic and may include components like wires, springs, or screws. Examples of removable orthodontic appliances include aligners, retainers, and space maintainers. The specific type and design of the appliance will depend on the individual patient's orthodontic needs and treatment goals.

Orthodontic appliance design refers to the creation and development of medical devices used in orthodontics, which is a branch of dentistry focused on the diagnosis, prevention, and correction of dental and facial irregularities. The design process involves creating a customized treatment plan for each patient, based on their specific needs and goals.

Orthodontic appliances can be removable or fixed and are used to move teeth into proper alignment, improve jaw function, and enhance the overall appearance of the smile. Some common types of orthodontic appliances include braces, aligners, palatal expanders, and retainers.

The design of an orthodontic appliance typically involves several factors, including:

1. The specific dental or facial problem being addressed
2. The patient's age, overall health, and oral hygiene habits
3. The patient's lifestyle and personal preferences
4. The estimated treatment time and cost
5. The potential risks and benefits of the appliance

Orthodontic appliance design is a complex process that requires a thorough understanding of dental anatomy, biomechanics, and materials science. It is typically performed by an orthodontist or a dental technician with specialized training in this area. The goal of orthodontic appliance design is to create a device that is both effective and comfortable for the patient, while also ensuring that it is safe and easy to use.

Functional Orthodontic Appliances are removable or fixed devices used in orthodontics to correct the alignment and/or positioning of jaw bones and/or teeth. They work by harnessing the power of muscle function and growth to achieve desired changes in the dental arches and jaws. These appliances are typically used in growing children and adolescents, but can also be used in adults in certain cases. Examples of functional orthodontic appliances include activators, bionators, twin blocks, and Herbst appliances. The specific type of appliance used will depend on the individual patient's needs and treatment goals.

Extraoral traction appliances are orthodontic devices used to correct significant dental and skeletal discrepancies, typically in cases of severe malocclusion. These appliances are worn externally on the face or head, and they work by applying gentle force to the teeth and jaws to guide them into proper alignment.

Extraoral traction appliances can be used to treat a variety of orthodontic problems, including:

* Protruding front teeth (overjet)
* Severe crowding or spacing
* Class II or Class III malocclusions (where the upper and lower jaws do not align properly)
* Jaw growth abnormalities

There are several types of extraoral traction appliances, including:

1. **Headgear:** This is the most common type of extraoral appliance. It consists of a metal frame that attaches to braces on the back teeth and a strap that fits around the head or neck. The strap applies pressure to the teeth and jaws, helping to correct alignment issues.
2. **Facemask:** A facemask is used to treat Class III malocclusions, where the lower jaw protrudes forward. It consists of a metal frame that attaches to braces on the upper teeth and a strap that fits around the head. The strap pulls the upper jaw forward, helping to align it with the lower jaw.
3. **Reverse pull headgear:** This type of appliance is used to treat patients with a receding chin or small lower jaw. It works by applying pressure to the back of the head, which encourages the growth and development of the lower jaw.
4. **Jaw separators:** These are used in cases where the jaws need to be separated to allow for proper alignment. They consist of two metal bars that fit over the upper and lower teeth, with a screw mechanism that gradually increases the space between them.

Extraoral traction appliances can be uncomfortable to wear at first, but most patients adjust to them over time. It is important to follow the orthodontist's instructions carefully when wearing these appliances to ensure proper alignment and prevent damage to the teeth and jaws.

Malocclusion, Angle Class II is a type of dental malocclusion where the relationship between the maxilla (upper jaw) and mandible (lower jaw) is such that the lower molar teeth are positioned posteriorly relative to the upper molar teeth. This results in an overbite, which means that the upper front teeth overlap the lower front teeth excessively. The classification was proposed by Edward Angle, an American orthodontist who is considered the father of modern orthodontics. In this classification system, Class II malocclusion is further divided into three subclasses (I, II, and III) based on the position of the lower incisors relative to the upper incisors.

Mandibular advancement is a treatment approach used in dentistry and sleep medicine, which involves the surgical or non-surgical forward movement of the mandible (lower jaw) to address certain medical conditions. The most common use of mandibular advancement is in the treatment of obstructive sleep apnea (OSA), where the tongue and soft tissues at the back of the throat can collapse into the airway during sleep, causing obstruction and breathing difficulties.

Mandibular advancement devices (MADs) are often used in non-surgical treatments. These custom-made oral appliances look similar to mouthguards or sports guards and are worn during sleep. They work by holding the lower jaw in a slightly forward position, which helps to keep the airway open and prevents the tongue and soft tissues from collapsing into it.

Surgical mandibular advancement is another option for patients with severe OSA who cannot tolerate or do not respond well to MADs or other treatments like continuous positive airway pressure (CPAP). In this procedure, the jaw is surgically moved forward and stabilized in that position using plates, screws, or wires. This creates more space in the airway and reduces the risk of obstruction during sleep.

In summary, mandibular advancement refers to the movement of the lower jaw forward, either through non-surgical means like MADs or surgical interventions, with the primary goal of treating obstructive sleep apnea by maintaining a patent airway during sleep.

Tooth movement, in a dental and orthodontic context, refers to the physical change in position or alignment of one or more teeth within the jaw bone as a result of controlled forces applied through various orthodontic appliances such as braces, aligners, or other orthodontic devices. The purposeful manipulation of these forces encourages the periodontal ligament (the tissue that connects the tooth to the bone) to remodel, allowing the tooth to move gradually over time into the desired position. This process is crucial in achieving proper bite alignment, correcting malocclusions, and enhancing overall oral function and aesthetics.

Orthodontics is a specialized branch of dentistry that focuses on the diagnosis, prevention, and treatment of dental and facial irregularities. The term "corrective" in this context refers to the use of appliances (such as braces, aligners, or other devices) to move teeth into their proper position and correct malocclusion (bad bite). This not only improves the appearance of the teeth but also helps to ensure better function, improved oral health, and overall dental well-being.

The goal of corrective orthodontics is to create a balanced and harmonious relationship between the teeth, jaws, and facial structures. Treatment may be recommended for children, adolescents, or adults and can help address various issues such as crowding, spacing, overbites, underbites, crossbites, open bites, and jaw growth discrepancies. A combination of techniques, including fixed or removable appliances, may be used to achieve the desired outcome. Regular follow-up appointments are necessary throughout treatment to monitor progress and make any necessary adjustments.

Occlusal splints, also known as bite guards or night guards, are removable dental appliances that are used to provide protection and stabilization for the teeth and jaw joint (temporomandibular joint or TMJ). They are typically made of hard acrylic or soft materials and are custom-fit to a patient's mouth.

Occlusal splints work by covering and separating the upper and lower teeth, preventing them from coming into contact with each other. This can help to reduce tooth grinding and clenching (bruxism), which can cause tooth wear, sensitivity, and TMJ disorders. They may also be used to help stabilize the jaw joint and muscles in patients with TMJ disorders or to provide protection for teeth that have undergone restorative dental work.

It is important to note that occlusal splints should only be worn under the guidance of a dentist, as improper use can lead to further dental problems.

Cephalometry is a medical term that refers to the measurement and analysis of the skull, particularly the head face relations. It is commonly used in orthodontics and maxillofacial surgery to assess and plan treatment for abnormalities related to the teeth, jaws, and facial structures. The process typically involves taking X-ray images called cephalograms, which provide a lateral view of the head, and then using various landmarks and reference lines to make measurements and evaluate skeletal and dental relationships. This information can help clinicians diagnose problems, plan treatment, and assess treatment outcomes.

The mandible, also known as the lower jaw, is the largest and strongest bone in the human face. It forms the lower portion of the oral cavity and plays a crucial role in various functions such as mastication (chewing), speaking, and swallowing. The mandible is a U-shaped bone that consists of a horizontal part called the body and two vertical parts called rami.

The mandible articulates with the skull at the temporomandibular joints (TMJs) located in front of each ear, allowing for movements like opening and closing the mouth, protrusion, retraction, and side-to-side movement. The mandible contains the lower teeth sockets called alveolar processes, which hold the lower teeth in place.

In medical terminology, the term "mandible" refers specifically to this bone and its associated structures.

Palatal expansion technique is a dental or orthodontic treatment procedure that aims to widen the upper jaw (maxilla) by expanding the palate. This is typically done using a device called a palatal expander, which is attached to the upper molars and applies pressure to gradually separate the two bones that form the palate (the maxillary bones). As the appliance is activated (usually through turning a screw or key), it gently expands the palatal suture, allowing for an increase in the width of the upper dental arch. This procedure can help correct crossbites, crowding, and other jaw alignment issues. It's commonly used in children and adolescents but may also be employed in adults with certain conditions.

The maxilla is a paired bone that forms the upper jaw in vertebrates. In humans, it is a major bone in the face and plays several important roles in the craniofacial complex. Each maxilla consists of a body and four processes: frontal process, zygomatic process, alveolar process, and palatine process.

The maxillae contribute to the formation of the eye sockets (orbits), nasal cavity, and the hard palate of the mouth. They also contain the upper teeth sockets (alveoli) and help form the lower part of the orbit and the cheekbones (zygomatic arches).

Here's a quick rundown of its key functions:

1. Supports the upper teeth and forms the upper jaw.
2. Contributes to the formation of the eye sockets, nasal cavity, and hard palate.
3. Helps shape the lower part of the orbit and cheekbones.
4. Partakes in the creation of important sinuses, such as the maxillary sinus, which is located within the body of the maxilla.

Tissue Plasminogen Activator (tPA) is a thrombolytic enzyme, which means it dissolves blood clots. It is naturally produced by the endothelial cells that line the interior surface of blood vessels. tPA activates plasminogen, a zymogen, to convert it into plasmin, a protease that breaks down fibrin, the structural protein in blood clots. This enzyme is used medically as a thrombolytic drug under various brand names, such as Activase and Alteplase, to treat conditions like acute ischemic stroke, pulmonary embolism, and deep vein thrombosis by dissolving the clots and restoring blood flow.

Retrognathia is a dental and maxillofacial term that refers to a condition where the mandible (lower jaw) is positioned further back than normal, relative to the maxilla (upper jaw). This results in the chin appearing recessed or set back, and can lead to various functional and aesthetic problems. In severe cases, retrognathia can interfere with speaking, chewing, and breathing, and may require orthodontic or surgical intervention for correction.

Orthodontic wires are typically made of stainless steel, nickel-titanium alloy, or other shape memory alloys, and are used in orthodontics to move teeth into the desired position. They are attached to brackets bonded to the teeth and exert a continuous force to align the teeth and correct malocclusions (bites that do not fit together correctly). The wires come in various sizes, shapes, and materials, each with specific properties that make them suitable for different stages of treatment. Some wires are flexible and used during the initial alignment phase, while others are more rigid and used during the finishing phase to achieve precise tooth movements.

An overbite, also known as "malocclusion of class II division 1" in dental terminology, is an orthodontic condition where the upper front teeth excessively overlap the lower front teeth when biting down. This means that the upper incisors are positioned too far forward or the lower incisors are too far back. A slight overbite is considered normal and healthy, as it allows the front teeth to perform their functions properly, such as biting and tearing food. However, a significant overbite can lead to various problems like difficulty in chewing, speaking, and maintaining good oral hygiene. It may also cause wear and tear on the teeth, jaw pain, or even contribute to temporomandibular joint disorders (TMD). Orthodontic treatment, such as braces or aligners, is often recommended to correct a severe overbite and restore proper bite alignment.

I'm sorry for any confusion, but "Household Articles" is not a term that has a specific medical definition. It generally refers to items or goods used in a household for everyday activities, such as cleaning supplies, dishes, furniture, and personal care products. However, in a medical context, it may refer to items that are commonly found in a household and could potentially pose a risk for injury or illness, such as medications, sharp objects, or cleaning products. It's always important to keep these items out of reach of children and pets, and to follow proper safety guidelines when using them.

The term "vertical dimension" is used in dentistry, specifically in the field of prosthodontics, to refer to the measurement of the distance between two specific points in the vertical direction when the jaw is closed. The most common measurement is the "vertical dimension of occlusion," which is the distance between the upper and lower teeth when the jaw is in a balanced and comfortable position during resting closure.

The vertical dimension is an important consideration in the design and fabrication of dental restorations, such as dentures or dental crowns, to ensure proper function, comfort, and aesthetics. Changes in the vertical dimension can occur due to various factors, including tooth loss, jaw joint disorders, or muscle imbalances, which may require correction through dental treatment.

In the context of dentistry, a molar is a type of tooth found in the back of the mouth. They are larger and wider than other types of teeth, such as incisors or canines, and have a flat biting surface with multiple cusps. Molars are primarily used for grinding and chewing food into smaller pieces that are easier to swallow. Humans typically have twelve molars in total, including the four wisdom teeth.

In medical terminology outside of dentistry, "molar" can also refer to a unit of mass in the apothecaries' system of measurement, which is equivalent to 4.08 grams. However, this usage is less common and not related to dental or medical anatomy.

Plasminogen Activator Inhibitor 1 (PAI-1) is a protein involved in the regulation of fibrinolysis, which is the body's natural process of breaking down blood clots. PAI-1 inhibits tissue plasminogen activator (tPA) and urokinase-type plasminogen activator (uPA), two enzymes that convert plasminogen to plasmin, which degrades fibrin clots. Therefore, PAI-1 acts as a natural antagonist of the fibrinolytic system, promoting clot formation and stability. Increased levels of PAI-1 have been associated with thrombotic disorders, such as deep vein thrombosis and pulmonary embolism.

Urokinase-type plasminogen activator (uPA) is a serine protease enzyme that plays a crucial role in the degradation of the extracellular matrix and cell migration. It catalyzes the conversion of plasminogen to plasmin, which then breaks down various proteins in the extracellular matrix, leading to tissue remodeling and repair.

uPA is synthesized as a single-chain molecule, pro-uPA, which is activated by cleavage into two chains, forming the mature and active enzyme. uPA binds to its specific receptor, uPAR, on the cell surface, where it exerts its proteolytic activity.

Abnormal regulation of uPA and uPAR has been implicated in various pathological conditions, including cancer, where they contribute to tumor invasion and metastasis. Therefore, uPA is a potential target for therapeutic intervention in cancer and other diseases associated with excessive extracellular matrix degradation.

Malocclusion is a term used in dentistry and orthodontics to describe a misalignment or misrelation between the upper and lower teeth when they come together, also known as the bite. It is derived from the Latin words "mal" meaning bad or wrong, and "occludere" meaning to close.

There are different types of malocclusions, including:

1. Class I malocclusion: The most common type, where the upper teeth slightly overlap the lower teeth, but the bite is otherwise aligned.
2. Class II malocclusion (overbite): The upper teeth significantly overlap the lower teeth, causing a horizontal or vertical discrepancy between the dental arches.
3. Class III malocclusion (underbite): The lower teeth protrude beyond the upper teeth, resulting in a crossbite or underbite.

Malocclusions can be caused by various factors such as genetics, thumb sucking, tongue thrusting, premature loss of primary or permanent teeth, and jaw injuries or disorders. They may lead to several oral health issues, including tooth decay, gum disease, difficulty chewing or speaking, and temporomandibular joint (TMJ) dysfunction. Treatment for malocclusions typically involves orthodontic appliances like braces, aligners, or retainers to realign the teeth and correct the bite. In some cases, surgical intervention may be necessary.

An incisor is a type of tooth that is primarily designed for biting off food pieces rather than chewing or grinding. They are typically chisel-shaped, flat, and have a sharp cutting edge. In humans, there are eight incisors - four on the upper jaw and four on the lower jaw, located at the front of the mouth. Other animals such as dogs, cats, and rodents also have incisors that they use for different purposes like tearing or gnawing.

Dental models are replicas of a patient's teeth and surrounding oral structures, used in dental practice and education. They are typically created using plaster or other materials that harden to accurately reproduce the shape and position of each tooth, as well as the contours of the gums and palate. Dental models may be used for a variety of purposes, including treatment planning, creating custom-fitted dental appliances, and teaching dental students about oral anatomy and various dental procedures. They provide a tactile and visual representation that can aid in understanding and communication between dentists, patients, and other dental professionals.

Dental occlusion, centric refers to the alignment and contact of the opposing teeth when the jaw is closed in a neutral position, specifically with the mandible (lower jaw) positioned in maximum intercuspation. This means that all teeth are in full contact with their corresponding teeth in the opposite jaw, and the condyles of the mandible are seated in the most posterior portion of the glenoid fossae (the sockets in the skull where the mandible articulates). Centric occlusion is an important concept in dentistry as it serves as a reference point for establishing proper bite relationships during restorative dental treatment.

Orthodontic retainers are dental appliances that are custom-made and used after orthodontic treatment (such as braces) to help maintain the new position of teeth. They can be fixed or removable and are designed to keep the teeth in place while the surrounding gums and bones stabilize in their new positions. Retainers play a crucial role in preserving the investment made during orthodontic treatment, preventing the teeth from shifting back to their original positions.

Maxillofacial development refers to the growth and formation of the bones, muscles, and soft tissues that make up the face and jaw (maxillofacial region). This process begins in utero and continues throughout childhood and adolescence. It involves the coordinated growth and development of multiple structures, including the upper and lower jaws (maxilla and mandible), facial bones, teeth, muscles, and nerves.

Abnormalities in maxillofacial development can result in a range of conditions, such as cleft lip and palate, jaw deformities, and craniofacial syndromes. These conditions may affect a person's appearance, speech, chewing, and breathing, and may require medical or surgical intervention to correct.

Healthcare professionals involved in the diagnosis and treatment of maxillofacial developmental disorders include oral and maxillofacial surgeons, orthodontists, pediatricians, geneticists, and other specialists.

Mixed dentition is a stage of dental development in which both primary (deciduous) teeth and permanent teeth are present in the mouth. This phase typically begins when the first permanent molars erupt, around the age of 6, and continues until all of the primary teeth have been replaced by permanent teeth, usually around the age of 12-13.

During this stage, a person will have a mix of smaller, temporary teeth and larger, more durable permanent teeth. Proper care and management of mixed dentition is essential for maintaining good oral health, as it can help to prevent issues such as crowding, misalignment, and decay. Regular dental check-ups and proper brushing and flossing techniques are crucial during this stage to ensure the best possible outcomes for long-term oral health.

Orthodontic brackets are small square attachments that are bonded to the teeth or bands that are attached to the back molars. They have a slot in which the orthodontic archwire fits and is held in place. The bracket can be made of stainless steel, ceramic, plastic or a combination of these materials. They play an essential role in moving the teeth into the desired position during orthodontic treatment.

The dental arch refers to the curved shape formed by the upper or lower teeth when they come together. The dental arch follows the curve of the jaw and is important for proper bite alignment and overall oral health. The dental arches are typically described as having a U-shaped appearance, with the front teeth forming a narrower section and the back teeth forming a wider section. The shape and size of the dental arch can vary from person to person, and any significant deviations from the typical shape or size may indicate an underlying orthodontic issue that requires treatment.

A bicuspid valve, also known as a mitral valve in the heart, is a heart valve that has two leaflets or cusps. It lies between the left atrium and the left ventricle and helps to regulate blood flow between these two chambers of the heart. In a healthy heart, the bicuspid valve opens to allow blood to flow from the left atrium into the left ventricle and closes tightly to prevent blood from flowing back into the left atrium during contraction of the ventricle.

A congenital heart defect known as a bicuspid aortic valve occurs when the aortic valve, which normally has three leaflets or cusps, only has two. This can lead to narrowing of the valve (aortic stenosis) or leakage of the valve (aortic regurgitation), which can cause symptoms and may require medical treatment.

Interceptive orthodontics refers to a branch of orthodontics that focuses on the early interception and treatment of dental or oral issues in children, typically between the ages of 6 and 10. The goal of interceptive orthodontics is to correct developing problems before they become more serious and require extensive treatment in the future.

Interceptive orthodontic treatments may include the use of appliances such as space maintainers, palatal expanders, or partial braces to guide the growth and development of the teeth and jaws. These treatments can help to:

* Create more space for crowded teeth
* Correct bite problems
* Improve facial symmetry
* Guide jaw growth and development
* Reduce the risk of tooth damage due to thumb sucking or tongue thrusting habits

By addressing these issues early on, interceptive orthodontics can help to prevent more extensive and costly treatments later in life. It is important to note that not all children will require interceptive orthodontic treatment, and a thorough evaluation by an orthodontist is necessary to determine the most appropriate course of action for each individual case.

The facial bones, also known as the facial skeleton, are a series of bones that make up the framework of the face. They include:

1. Frontal bone: This bone forms the forehead and the upper part of the eye sockets.
2. Nasal bones: These two thin bones form the bridge of the nose.
3. Maxilla bones: These are the largest bones in the facial skeleton, forming the upper jaw, the bottom of the eye sockets, and the sides of the nose. They also contain the upper teeth.
4. Zygomatic bones (cheekbones): These bones form the cheekbones and the outer part of the eye sockets.
5. Palatine bones: These bones form the back part of the roof of the mouth, the side walls of the nasal cavity, and contribute to the formation of the eye socket.
6. Inferior nasal conchae: These are thin, curved bones that form the lateral walls of the nasal cavity and help to filter and humidify air as it passes through the nose.
7. Lacrimal bones: These are the smallest bones in the skull, located at the inner corner of the eye socket, and help to form the tear duct.
8. Mandible (lower jaw): This is the only bone in the facial skeleton that can move. It holds the lower teeth and forms the chin.

These bones work together to protect vital structures such as the eyes, brain, and nasal passages, while also providing attachment points for muscles that control chewing, expression, and other facial movements.

"Mesial movement of teeth" is a dental term that refers to the natural drifting or shifting of teeth in a forward direction towards the front of the mouth. This movement typically occurs over time and can be influenced by various factors such as:

* The loss of adjacent teeth, which can create space for other teeth to move into
* Oral habits like thumb sucking or tongue thrusting
* Periodontal disease that weakens the supporting structures of the teeth
* Malocclusion or misalignment of teeth

It is essential to monitor and manage mesial movement of teeth to prevent dental issues such as crowding, malocclusion, and periodontal problems. Dental professionals may use various treatments, including orthodontic appliances, space maintainers, or restorations, to address this issue.

Dental alloys are materials made by combining two or more metals to be used in dental restorations, such as crowns, bridges, fillings, and orthodontic appliances. These alloys can be classified into three main categories based on their composition:

1. Precious Alloys: Predominantly composed of precious metals like gold, platinum, palladium, and silver. They are highly corrosion-resistant, biocompatible, and durable, making them suitable for long-term use in dental restorations. Common examples include high noble (gold) alloys and noble alloys.
2. Base Metal Alloys: Contain primarily non-precious metals like nickel, chromium, cobalt, and beryllium. They are more affordable than precious alloys but may cause allergic reactions or sensitivities in some patients. Common examples include nickel-chromium alloys and cobalt-chromium alloys.
3. Castable Glass Ionomer Alloys: A combination of glass ionomer cement (GIC) powder and metal liquid, which can be cast into various dental restorations. They have the advantage of being both strong and adhesive to tooth structure but may not be as durable as other alloy types.

Each type of dental alloy has its unique properties and applications, depending on the specific clinical situation and patient needs. Dental professionals consider factors like cost, biocompatibility, mechanical properties, and esthetics when selecting an appropriate alloy for a dental restoration.

Malocclusion, Angle Class III is a type of orthodontic problem characterized by a misalignment of the teeth and jaws. This classification was first described by Edward Angle, an American dentist who is considered the father of modern orthodontics. In Class III malocclusion, the lower jaw (mandible) protrudes forward beyond the upper jaw (maxilla), resulting in a misaligned bite.

In this condition, the lower front teeth are positioned in front of the upper front teeth when the jaws are closed. This can lead to various dental and skeletal problems, such as abnormal tooth wear, difficulty in chewing and speaking, and aesthetic concerns. Class III malocclusion can be mild, moderate, or severe and may require orthodontic treatment, including braces, appliances, or even surgery, to correct the problem.

Malocclusion, Angle Class I is a type of dental malocclusion where the misalignment of teeth is not severe enough to affect the overall function or appearance of the bite significantly. Named after Edward Angle, the founder of modern orthodontics, this classification indicates that the mesiobuccal cusp of the upper first molar is aligned with the buccal groove of the lower first molar. Although the bite appears normal, there might be crowding, spacing, or rotations present in the teeth, which can lead to aesthetic concerns and potential periodontal issues if left untreated.

Orthodontics is a specialized branch of dentistry that focuses on the diagnosis, prevention, and treatment of dental and facial irregularities. This involves correcting teeth that are improperly positioned, often using braces or other appliances to move them into the correct position over time. The goal of orthodontic treatment is to create a healthy, functional bite and improve the appearance of the teeth and face.

Orthodontists are dental specialists who have completed additional training beyond dental school in order to become experts in this field. They use various techniques and tools, such as X-rays, models of the teeth, and computer imaging, to assess and plan treatment for each individual patient. The type of treatment recommended will depend on the specific needs and goals of the patient.

Orthodontic treatment can be beneficial for people of all ages, although it is most commonly started during childhood or adolescence when the teeth and jaws are still growing and developing. However, more and more adults are also seeking orthodontic treatment to improve their smile and oral health.

Dental occlusion refers to the alignment and contact between the upper and lower teeth when the jaws are closed. It is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or biting.

A proper dental occlusion, also known as a balanced occlusion, ensures that the teeth and jaw joints function harmoniously, reducing the risk of tooth wear, damage, and temporomandibular disorders (TMD). Malocclusion, on the other hand, refers to improper alignment or contact between the upper and lower teeth, which may require orthodontic treatment or dental restorations to correct.

Jaw fixation techniques, also known as maxillomandibular fixation (MMF), are procedures used in dental and oral surgery to hold the jaw in a specific position. This is typically done by wiring the upper and lower teeth together or using elastic bands and other devices to keep the jaws aligned. The technique is often used after surgical procedures on the jaw, such as corrective jaw surgery (orthognathic surgery) or fracture repair, to help promote proper healing and alignment of the bones. It may also be used in the management of temporomandibular joint disorders or other conditions affecting the jaw. The duration of jaw fixation can vary depending on the specific procedure and individual patient needs, but it typically lasts several weeks.

Urokinase Plasminogen Activator Receptors (uPAR) are a type of cell surface receptor that play a role in several biological processes including cell migration, tissue remodeling, and angiogenesis. They bind to urokinase plasminogen activator (uPA), a serine protease that converts plasminogen to plasmin, leading to the degradation of extracellular matrix components.

The interaction between uPAR and uPA plays a crucial role in various physiological processes such as wound healing and tissue repair, but it has also been implicated in several pathological conditions, including cancer, where it contributes to tumor cell invasion and metastasis. The regulation of uPAR expression and activity is therefore an important area of research for the development of new therapeutic strategies.

In medical terms, a "lip" refers to the thin edge or border of an organ or other biological structure. However, when people commonly refer to "the lip," they are usually talking about the lips on the face, which are part of the oral cavity. The lips are a pair of soft, fleshy tissues that surround the mouth and play a crucial role in various functions such as speaking, eating, drinking, and expressing emotions.

The lips are made up of several layers, including skin, muscle, blood vessels, nerves, and mucous membrane. The outer surface of the lips is covered by skin, while the inner surface is lined with a moist mucous membrane. The muscles that make up the lips allow for movements such as pursing, puckering, and smiling.

The lips also contain numerous sensory receptors that help detect touch, temperature, pain, and other stimuli. Additionally, they play a vital role in protecting the oral cavity from external irritants and pathogens, helping to keep the mouth clean and healthy.

Plasminogen activators are a group of enzymes that play a crucial role in the body's fibrinolytic system, which is responsible for breaking down and removing blood clots. These enzymes activate plasminogen, a zymogen (inactive precursor) found in circulation, converting it into plasmin - a protease that degrades fibrin, the insoluble protein mesh that forms the structural basis of a blood clot.

There are two main types of plasminogen activators:

1. Tissue Plasminogen Activator (tPA): This is a serine protease primarily produced by endothelial cells lining blood vessels. tPA has a higher affinity for fibrin-bound plasminogen and is therefore more specific in activating plasmin at the site of a clot, helping to localize fibrinolysis and minimize bleeding risks.
2. Urokinase Plasminogen Activator (uPA): This is another serine protease found in various tissues and body fluids, including urine. uPA can be produced by different cell types, such as macrophages and fibroblasts. Unlike tPA, uPA does not have a strong preference for fibrin-bound plasminogen and can activate plasminogen in a more general manner, which might contribute to its role in processes like tissue remodeling and cancer progression.

Plasminogen activators are essential for maintaining vascular homeostasis by ensuring the proper removal of blood clots and preventing excessive fibrin accumulation. They have also been implicated in various pathological conditions, including thrombosis, hemorrhage, and tumor metastasis.

Orthodontic anchorage procedures refer to the methods and techniques used in orthodontics to achieve stable, controlled movement of teeth during treatment. The term "anchorage" describes the point of stability around which other teeth are moved.

There are two main types of anchorage: absolute and relative. Absolute anchorage is when the force applied to move teeth does not cause any unwanted movement in the area providing stability. Relative anchorage is when some degree of reciprocal movement is expected in the area providing stability.

Orthodontic appliances, such as mini-screws, palatal implants, and headgear, are often used to provide additional anchorage reinforcement. These devices help control the direction and magnitude of forces applied during treatment, ensuring predictable tooth movement and maintaining proper alignment and occlusion (bite).

In summary, orthodontic anchorage procedures involve the strategic use of various appliances and techniques to establish a stable foundation for moving teeth during orthodontic treatment. This helps ensure optimal treatment outcomes and long-term stability of the dentition.

Root resorption is a process that occurs when the body's own cells, called odontoclasts, break down and destroy the hard tissue of the tooth root. This can occur as a result of various factors such as trauma, infection, or orthodontic treatment. In some cases, it may be a normal part of the tooth development and eruption process in children. However, excessive or pathological root resorption can lead to weakening and loss of the tooth. It is often asymptomatic and discovered during routine dental x-rays.

I'm sorry for any confusion, but "Stainless Steel" is not a medical term. It is a type of steel that contains at least 10.5% chromium content by mass, and usually contains nickel as well. The chromium forms a passive film that protects the metal from corrosion and staining. Stainless steel is widely used in various industries including medicine, for example, in medical equipment and surgical instruments due to its resistance to rust and corrosion.

The dental plaque index (DPI) is a clinical measurement used in dentistry to assess the amount of dental plaque accumulation on a person's teeth. It was first introduced by Silness and Löe in 1964 as a method to standardize the assessment of oral hygiene and the effectiveness of oral hygiene interventions.

The DPI is based on a visual examination of the amount of plaque present on four surfaces of the teeth, including the buccal (cheek-facing) and lingual (tongue-facing) surfaces of both upper and lower first molars and upper and lower incisors. The examiner assigns a score from 0 to 3 for each surface, with higher scores indicating greater plaque accumulation:

* Score 0: No plaque detected, even after probing the area with a dental explorer.
* Score 1: Plaque detected by visual examination and/or probing but is not visible when the area is gently dried with air.
* Score 2: Moderate accumulation of soft deposits that are visible upon visual examination before air drying, but which can be removed by scraping with a dental explorer.
* Score 3: Abundant soft matter, visible upon visual examination before air drying and not easily removable with a dental explorer.

The DPI is calculated as the average score of all surfaces examined, providing an overall measure of plaque accumulation in the mouth. It can be used to monitor changes in oral hygiene over time or to evaluate the effectiveness of different oral hygiene interventions. However, it should be noted that the DPI has limitations and may not accurately reflect the presence of bacterial biofilms or the risk of dental caries and gum disease.

Dental esthetics refers to the branch of dentistry concerned with the aesthetic appearance of teeth and smile. It involves the use of various dental treatments and procedures to improve the color, shape, alignment, and position of teeth, thereby enhancing the overall facial appearance and self-confidence of a person. Some common dental esthetic treatments include tooth whitening, dental veneers, composite bonding, orthodontic treatment (braces), and dental implants. It is important to note that dental esthetics not only focuses on improving the appearance but also maintaining or improving oral health and function.

The mandibular condyle is a part of the temporomandibular joint (TMJ) in the human body. It is a rounded eminence at the end of the mandible (lower jawbone) that articulates with the glenoid fossa of the temporal bone in the skull, allowing for movements such as opening and closing the mouth, chewing, speaking, and swallowing. The mandibular condyle has both a fibrocartilaginous articular surface and a synovial joint capsule surrounding it, which provides protection and lubrication during these movements.
