Hydroxyapatite-coated femoral stems. Histology and histomorphometry around five components retrieved at post mortem. (1/500)

We performed a histological and histomorphometric examination in five cadaver specimens of the femoral and acetabular components and the associated tissue which had been recovered between 3.3 and 6.2 years after primary total hip arthroplasty (THA) using a proximal hydroxyapatite (HA)-coated titanium alloy implant. All had functioned well during the patients' life. All the stems were fixed in the femur and showed osseointegration of both the proximal and distal parts. The amount of residual HA was greatest in the distal metaphyseal sections, indicating that the rate of bone remodelling may be the main factor causing loss of HA. The level of activity of the patient was the only clinical factor which correlated with loss of coating. The percentage of bone-implant osseointegration was almost constant, regardless of the amount of HA residue, periprosthetic bone density or the time of implantation. HA debris was seldom observed and if present did not cause any adverse or inflammatory reaction. Partial debonding did occur in one case as a result of a polyethylene-induced inflammatory reaction.  (+info)

Coating titanium implants with bioglass and with hydroxyapatite. A comparative study in sheep. (2/500)

This study compares the osteointegration of titanium implants coated with bioglass (Biovetro GSB formula) and with hydroxyapatite (HAP). Twenty-four bioglass-coated and 24 HAP-coated cylinders were implanted in the femoral diaphyses of sheep, and examined after 2, 4, 6, 8, 12, and 16 weeks. The HAP coating gave a stronger and earlier fixation to the bone than did bioglass. Bioglass formed a tissue interface which showed a macrophage reaction with little new bone formation activity. In contrast, HPA, showed intense new bone formation, with highly mineralised osseous trabeculae in the neighbourhood of the interface.  (+info)

Xenogenic demineralized bone matrix: osteoinduction and influence of associated skeletal defects in heterotopic bone formation in rats. (3/500)

Demineralized bone matrix (DBM) was ectopically implanted in 36 male Wistar rats. In 18 of the animals a bone defect in the femoral condyles was also created: the left was filled with DBM and the right was left empty as a control. The animals were killed after 2, 4 and 6 weeks and new bone was histologically evaluated, comparing ectopic bone formation with or without distant bone injury. Results showed: (1) osteoinductivity of xenogenic DBM, and (2) earlier mineralization of ectopically implanted DBM in the group with associated skeletal injury. Our results show that xenogenic bone matrix acts as an osteoinductive material and that skeletal injury improves osteogenesis at distant sites.  (+info)

Characteristics of bone ingrowth and interface mechanics of a new porous tantalum biomaterial. (4/500)

We have studied the characteristics of bone ingrowth of a new porous tantalum biomaterial in a simple transcortical canine model using cylindrical implants 5 x 10 mm in size. The material was 75% to 80% porous by volume and had a repeating arrangement of slender interconnecting struts which formed a regular array of dodecahedron-shaped pores. We performed histological studies on two types of material, one with a smaller pore size averaging 430 microm at 4, 16 and 52 weeks and the other with a larger pore size averaging 650 microm at 2, 3, 4, 16 and 52 weeks. Mechanical push-out tests at 4 and 16 weeks were used to assess the shear strength of the bone-implant interface on implants of the smaller pore size. The extent of filling of the pores of the tantalum material with new bone increased from 13% at two weeks to between 42% and 53% at four weeks. By 16 and 52 weeks the average extent of bone ingrowth ranged from 63% to 80%. The tissue response to the small and large pore sizes was similar, with regions of contact between bone and implant increasing with time and with evidence of Haversian remodelling within the pores at later periods. Mechanical tests at four weeks indicated a minimum shear fixation strength of 18.5 MPa, substantially higher than has been obtained with other porous materials with less volumetric porosity. This porous tantalum biomaterial has desirable characteristics for bone ingrowth; further studies are warranted to ascertain its potential for clinical reconstructive orthopaedics.  (+info)

Effects of TGFbeta on bone ingrowth in the presence of polyethylene particles. (5/500)

We implanted bone harvest chambers (BHCs) bilaterally in ten mature male New Zealand white rabbits. Polyethylene particles (0.3+/-0.1 microm in diameter, 6.4 x 10(12) particles/ml) were implanted for two, four or six weeks bilaterally in the BHCs, with subsequent removal of the ingrown tissue after each treatment. In addition to the particles, one side also received 1.5 microg of recombinant transforming growth factor beta1 (TGFbeta1). At two weeks, the bone area as a percentage of total area was less in chambers containing TGFbeta compared with those with particles alone (7.8+/-1.3% v 16.9+/-2.7% respectively; 95% confidence interval (CI) for difference -14.0 to -4.30; p = 0.002). At four weeks, the percentage area of bone was greater in chambers containing TGFbeta compared with those with particles alone (31.2+/-3.4% v 22.5+/-2.0% respectively; 95% CI for difference 1.0 to 16.4; p = 0.03). There were no statistical differences at six weeks, despite a higher mean value with TGFbeta treatment (38.2+/-3.9% v 28.8 +/-3.5%; 95% CI for difference -4.6 to 23.3; p = 0.16). The number of vitronectin-receptor-positive cells (osteoclast-like cells) was greater in the treatment group with TGFbeta compared with that with particles alone; most of these positive cells were located in the interstitium, rather than adjacent to bone. TGFbeta1 is a pleotropic growth factor which can modulate cellular events in the musculoskeletal system in a time- and concentration-dependent manner. Our data suggest that there is an early window at between two and six weeks, in which TGFbeta may favourably affect bone ingrowth in the BHC model. Exogenous growth factors such as TGFbeta may be a useful adjunct in obtaining osseointegration and bone ingrowth, especially in revisions when there is compromised bone stock and residual particulate debris.  (+info)

Influence of extracorporeal irradiation on the reintegration of autologous grafts of bone and joint. Study in a canine model. (6/500)

We studied the effects of irradiation on the reintegration of autologous osteoarticular grafts over a period of 24 weeks in a canine model. In 16 foxhounds the medial femoral condyle was resected, irradiated and immediately replanted. In the control group resection and replantation were performed without irradiation. Reintegration was assessed by macroscopic analysis, histology, radiography and gait analysis. Reintegration was equal at 12 weeks, but significantly inferior in the irradiated group after 24 weeks with delayed bone remodelling. The articular cartilage showed modest degeneration. Conventional radiography and histology showed corresponding changes. Limb function was adequate but the gait was inferior in the treated group.  (+info)

Osseointegration of Ti6Al4V alloy implants coated with titanium nitride by a new method. (7/500)

Coating titanium alloy implants with titanium nitride (TiN) by the method of Powder Immersion Reaction Assisted Coating (PIRAC) produces a stable layer on their surface. We have examined the ability of the new TiN coating to undergo osseointegration. We implanted TiN-coated and uncoated Ti6Al4V alloy pins into the femora of six-month-old female Wistar rats. SEM after two months showed a bone collar around both TiN-coated and uncoated implants. Morphometrical analysis revealed no significant differences between the percentage of the implant-bone contact and the area and volume of the bone around TiN-coated compared with uncoated implants. Electron-probe microanalysis indicated the presence of calcium and phosphorus at the implant-bone interface. Mineralisation around the implants was also confirmed by labelling with oxytetracycline. Strong activity of alkaline phosphatase and weak activity of tartrate-resistant acid phosphatase were shown histochemically. Very few macrophages were detected by the non-specific esterase reaction at the site of implantation. Our findings indicate good biocompatibility and bone-bonding properties of the new PIRAC TiN coatings which are comparable to those of uncoated Ti6Al4V alloy implants.  (+info)

The fixation of the cemented femoral component. Effects of stem stiffness, cement thickness and roughness of the cement-bone surface. (8/500)

After cemented total hip arthroplasty (THA) there may be failure at either the cement-stem or the cement-bone interface. This results from the occurrence of abnormally high shear and compressive stresses within the cement and excessive relative micromovement. We therefore evaluated micromovement and stress at the cement-bone and cement-stem interfaces for a titanium and a chromium-cobalt stem. The behaviour of both implants was similar and no substantial differences were found in the size and distribution of micromovement on either interface with respect to the stiffness of the stem. Micromovement was minimal with a cement mantle 3 to 4 mm thick but then increased with greater thickness of the cement. Abnormally high micromovement occurred when the cement was thinner than 2 mm and the stem was made of titanium. The relative decrease in surface roughness augmented slipping but decreased debonding at the cement-bone interface. Shear stress at this site did not vary significantly for the different coefficients of cement-bone friction while compressive and hoop stresses within the cement increased slightly.  (+info)

TY - JOUR. T1 - Osseointegration of dental implants in Macaca fascicularis. AU - Sari, Ratna. AU - Luddin, Roselani Widajati. AU - Odelia, L.. PY - 2017/8/30. Y1 - 2017/8/30. N2 - Osseointegration is an important factor in determining the success of a dental implant. It can be assessed from the osseointegration that occurs between the implant and the bone. The implant stability is determined by the osseous support at the implant-bone interface, which is commonly evaluated by histomorphometric analysis. This study aimed to evaluate whether the osseointegration level measured by a Low Resonance Frequency Analyzer (LRFA) gave results as good as those obtained by histomorphometric examination. Six male Macaca fascicularis were used in this study. In each animal, two types of loading were performed: immediate and delayed loading. Clinical examination and LRFA measurement were performed to determine osseointegration at the first and second weeks and at the first, second, third, and fourth months. ...
Implant osseointegration is a prerequisite for clinical achievement in orthopaedic and dental applications many of which are restricted by loosening. to enhanced osteoblastic function compared to unmodified titanium. Furthermore this integrin-targeted coating significantly improved peri-implant bone regeneration and osseointegration as characterized by bone-implant contact and mechanical fixation compared to untreated titanium in a rat cortical bone-implant model. GFOGER-modified implants also significantly enhanced osseointegration compared to surfaces modified with full-length type Anacetrapib I collagen highlighting the importance of presenting specific Anacetrapib biofunctional domains within the native ligand. In addition this biomimetic implant coating is generated using a simple single-step procedure that readily translates to a clinical environment with minimal processing and cytotoxicity concerns. Therefore this study establishes a biologically active and clinically relevant implant ...

Osseointegration refers to the direct connection between living bone and the surface of a load-bearing artificial implant. Porous implants with well-controlled porosity and pore size can enhance osseointegration. However, until recently implants were produced by machining solid core titanium rods. The aim of this study was to develop a multi-rooted dental implant (MRI) with a connected porous surface structure to facilitate osseointegration. MRIs manufactured by selective laser melting (SLM) and commercial implants with resorbable blasting media (RBM)-treated surfaces were inserted into the hind limbs of New Zealand white rabbits. Osseointegration was evaluated periodically over 12 weeks by micro-computerized tomography (CT) scanning, histological analysis, mechanical push-out tests, and torque tests. Bone volume densities were consistently higher in the MRI group than in the RBM group throughout the study period, ultimately resulting in a peak value of 48.41 % for the MRI group.

DOI: 10.11607/prd.00.0290 The present case report provides histologic findings on four titanium plasma-sprayed screw implants after 12 years of incorporation and functional load in a 95-year-old patient. At the time of implant placement, the four implants were immediately connected with a bar and functionally loaded with a bar-supported overdenture. The histologic analysis demonstrated excellent osseointegration in either cortical or cancellous bone for all implants. The histomorphometric analysis showed direct bone-implant contact of approximately 70% to 80% at the interface. Close to the implant surface, signs of ongoing bone remodeling activities were present. The present histologic case report confirms the validity of the applied treatment concept--to immediately load titanium implants with a titanium plasma-sprayed surface in the anterior region of the mandible--if a minimum of four implants can be inserted and if the four implants are splinted with a bar ...
One of the key factors controlling bone remodeling at the molecular level is the strain in the surrounding environment. The strain is defined as the change in length divided by the original length. The strain is created when any object is subjected to external stress. In the oral environment, this stress is the occlusal load. The occlusal stresses on the implant prosthesis are transmitted at implant-bone interface 80. The mechanoreceptors present in the bone respond to these stresses and initiate bone remodeling. These mechano-receptors are very sensitive and the microstrain levels 100 times less than the ultimate strength of bone may trigger bone remodeling 81. If the implant is subjected to TFO, high levels of stress are imposed at the implant-bone interface, initiating bone resorption leading to implant failure.. Another important mechanical factor is the modulus of elasticity (stiffness of a material). The modulus conveys the amount of dimensional change in a material for a given stress ...

In this study, different loading regimes were applied in order to evaluate the stimulatory effect of HF (i.e. 40 Hz) and LF (i.e. 2 Hz) mechanical loading on implant osseointegration and peri-implant bone formation. In order to assess additionally the influence of the loading magnitude, two loading forces varying by twofold within each frequency category were assigned.. According to Frost [21], loads on bones cause bone strains that generate signals detected by osteocytes and hence lead to cellular response and eventually to bone remodelling. The anabolic effect of loading on bone is evident when the bone strain induced by LF loading goes beyond the 1000 με threshold [21]. However, this does not apply to a HF loading protocol, where LM events have been shown to be stimulatory to the bone [2]. We intended to test whether the latter also applies to for peri-implant bone healing. With respect to the configuration limitations of the loading setup, 40 and 2 Hz were selected as HF and LF, ...
Ti is the material most commonly used for bone implants as it has outstanding physical and biological properties, such as low density, high mechanical strength, and good corrosion resistance. Current dental implant research aims at the production of innovative surfaces able to promote a more favorable biological response to the implant material at the bone-implant interface and to accelerate osseointegration. The modification of titanium (Ti) implants with therapeutic agents allows a better biological response to the implant material whilst improves osseointegration. Our invention refers to a biocompatible and bioactive surface coated with a precursor of Vitamin D - UV-activated 7-dehydrocholesterol (7-DHC). After implantation, the coating is used by the bone cells to locally produce active vitamin D, which stimulates bone formation ...
INTRODUCTION. Bone grafts are widely used for the reconstruction of atrophic alveolar ridges. Autogenous bone and replacement bones have been analyzed in different scenarios, yielding results that vary based on different research models and characteristics of the bone defects.. Thus, it has been determined that particle size is a factor in bone regeneration capacity (Klüppel et al., 2013) and that the vascularization properties of the recipient bed might also be relevant in bone integration (de Oliveira et al., 2013). The types of materials used as well as their agents of application are also factors that may permit enhanced adaptation and bone integration of the defect (Duque Netto et al., 2013). Within this wide network of factors that might influence tissue regeneration capacity, the continuous autogenous graft is the gold standard in bone integration (Olate et al., 2007), such that its use as a control in different studies is an important element.. Being aware of the biological processes ...

TY - GEN. T1 - Cracks emanating from defects in PMMA near a bone-implant interface. AU - Gharpuray, V. M.. AU - Keer, L. M.. AU - Lewis, J. L.. PY - 1991/1/1. Y1 - 1991/1/1. N2 - We hypothesize that cracks initiate and propagate within the initially firmly fixed cement and eventually lead to loss of implant fixation. To develop this hypothesis, mechanical failure processes were experimentally studied at the bone-cement-implant interface by cyclically loading tibial components that were fixed to cadaver tibias with polymethylmethacrylate (PMMA) using established surgical procedures. The obtained solutions give insight into possible failure processes occurring in bone cement under compression. However, the importance of these processes, relative to similar processes in other parts of the bone-cement-implant system must still be determined..

Effectiveness of resonance frequency in predicting orthopedic implant strength and stability in an in vitro osseointegration model.
Zirconia implants have been recommended as a possible alternative to traditional titanium implants.1 Compared with titanium implants, zirconia implants show favourable results regarding biocompatibility, soft-tissue reaction and aesthetic outcomes.2, 3 Although two-piece zirconia implants are available in the market, the long-term prognosis of this design is still unknown.4, 5 One-piece zirconia implants have demonstrated satisfactory results;6, 7however, with the one-piece design, there are signifi-cant challenges for both clinicians and patients during the healing time. For clinicians, occlusal forces may be applied to the implants before they are osseointegrated. This increases the risk of failure if the forces are too great or if the initial implant stability is less than ideal.8 For patients, the main concerns are related to maintaining aesthetics and function during the healing time.... ePaper PDF ...

The anterior maxilla is the most challenging region of the dentition to restore (Fig 9-1).1, 2, 3, 4 Bone grafting to support esthetics is key in this prominent area because the underlying ridge must support both the implant restoration and the soft tissue to achieve a long-lasting, esthetic result. These factors are particularly important in cases involving two or more teeth. Osseointegration of dental implants, particularly in the anterior maxilla, depends on adequate trabecular bone density, ridge height and width,5 and systemic bone health. The clinician must evaluate all of these factors to ensure that implants can maintain osseointegration during function. 6, 7, 8, 9, 10, 11 Furthermore, the clinician must take advantage of all available clinical, laboratory, and communication technologies to meet the patients functional and esthetic needs.12. Bone augmentation is required when anterior tooth loss leads to the loss of bone volume needed for proper implant positioning. 13, 14 The diameter ...

An implantable prosthesis has a plurality of grooves formed on a surface to promote biological fixation to the surrounding tissue. The grooves are preferably substantially equal in width, depth and spacing. The width of the grooves ranges from 350-535 microns, and the depth ranges from 380-635 microns. The spacing between adjacent grooves is substantially equal to the width and/or depth of the grooves. A preferred embodiment of the prosthesis of the present invention is a femoral stem for a hip joint which has a plurality of grooves, extending generally transversely to a longitudinal axis of the stem, formed on proximal portions of selected surfaces of the stem. Distal portions of the stem surfaces are relatively smooth. The grooves are oriented approximately perpendicularly to a line of force transmitted from the head to the shank of the stem. The grovoes preferably lie in planes which intersect the longitudinal axis of the shank at an angle of approximately 60°-80°. In the illustrated

Preparations of autologous plasma rich in growth factors (PRGF) are used to promote healing and tissue regeneration. We seek to determine whether covering the titanium implant surface with this preparation could enhance osseointegration. The interaction of PRGF with the surface of titanium implants was examined by environmental scanning electron microscopy (ESEM). A total of 23 implants were placed in the tibiae and radii of 3 goats; 13 implants were inserted after covering the surface and filling the alveolus with PRGF, and 10 more implants were inserted following a conventional protocol and served as controls. Histomorphometric analysis of the bone-implant interface was performed after 8 weeks. Finally, 1391 implants were placed in 295 patients after bioactivating the surface with PRGF. Stability and implant survival were evaluated. The implant surface adsorbed the protein-rich material as shown by ESEM. In the animal study, osseointegration was enhanced when the surface was covered with PRGF ...

to mega dental implant manufacturer, Zimmer. They have tranferred it from use in hip implants to dental implants. The trabecular metal material structure and stiffness similar to trabecular bone and is fabricated by coating a vitreous carbon skeleton with tantalum through a proprietary chemical vapor deposition coating process. The tantalum exhibits a crystallographic growth on the vitreous carbon surface of the interconnecting struts that form the material. Trabecular metal technology differs from sintered bead surfaces, titanium plasma-sprayed surfaces, titanium fiber mesh and titanium foam in the high degree of its interconnected porosity (up to 80%) and the regularity of its pore size and shape. In contrast to conventional bone-to-implant contact achieved by non-porous surfaces, Trabecular Metal Technologys geometrical network of interconnected pores is designed for biological ingrowth through the pores.. The implants coronal, apical and internal implant structures are made of titanium ...
BACKGROUND: Wear particles, found at the bone-implant interface surrounding a loose prosthesis, are commonly phagocytosed by macrophages. Wear particles and wear particle-containing macrophages are also found in regional lymph nodes draining arthroplasty tissues. The means by which wear particles are transported from arthroplasty tissues to lymph nodes is uncertain, as the presence or absence of lymphatic vessels in periprosthetic tissues has not been established. METHODS: We determined immunophenotypic expression of LYVE-1 and podoplanin, two highly specific lymphatic endothelial cell markers, in the hip arthroplasty pseudocapsule surrounding the false joint and the bone-implant interface of the femoral and acetabular pseu-domembrane. RESULTS: LYVE-1+/podoplanin+ lymphatic vessels were not identified in the pseudomembrane but were found in the pseudocapsule. Normal bone did not contain lymphatic vessels. INTERPRETATION: Our findings suggest that the wear particles shed at the bone-implant interface are
Fibrous encapsulation can impair implant osseointegration and cause implant failure but currently there are limited strategies to address this problem. Since bisphosphonates (BPs), a class of drugs widely used to treat bone diseases, was recently found to induce fibroblast apoptosis, we hypothesize that by loading BPs on titanium (Ti) implant surface, fibrous encapsulation may be inhibited with simultaneous enhancement of implant osseointegration. This strategy of local administration can also be expected to minimize the adverse side effects of BPs, which are associated with intravenous injections. To verify this hypothesis, alendronate was loaded on Ti surface via a hydroxyapatite (CaP) coating, and the effects of the loaded alendronate on fibroblast proliferation and apoptosis, and osteoblast proliferation, alkaline phosphatase (ALP) activity, and apoptosis were investigated in vitro. With a surface density of loaded alendronate 0.046 mg/cm2 or higher, fibroblast proliferation was suppressed ...
Titanium implants are nowadays often used in orthopedics and dentistry to repair or replace bone injuries or defects caused by aging, accident or diseases. Even if titanium is biocompatible, a low osseointegration between the implant and the surrounding tissue may result in graft rejection and a series of unwanted reactions. To overcome these issues, two main strategies have been investigated: a physicochemical modification of the implant surface (e.g. roughness, energy or chemistry of the surface) or a functionalization of the surface with cell adhesive molecules. This research project will mainly focus on the second approach which consists on the biofunctionalization of the surface. There are many types of cell adhesive molecules that can be used for such purpose. One of the most common family of cell adhesive molecules used are the proteins found in the extra cellular matrix (ECM).The cell bonding activity of these proteins is usually contained within a few amino acids. This is the case of ...
To study the effects of different designs in single mandibular molar implant restoration on the stress distribution of implant-bone interface. Methods: Three-dimensional finite element method were used. Results: When wide-diameter implant or two-implant were used to replace single mandibular molar, the stress of implant-bone interface was much lower than that of standard-diameter implant restoration. Comparison between wide-diameter implant and two-implant replacement showed that the former created lower stress. The difference was more obvious under oblique loads. Conclusion: Using wide-diameter implant or two-implant to restore single mandibular molar should be recommended in clinical practice. If adequate bone quantity is provided, using wide-diameter implant should be better.
There is a lack of histological information about the influence of cigarette smoke on bone around surface-treated implants. The aim of the present study was to test the influence of titanium surface treatment on osseointegration in animals that were exposed to intermittent cigarette smoke inhalation. Twenty-two male Wistar rats were used. One tibia, chosen at random, received a machined titanium implant (MI) while the other received an aluminum oxide-blasted surface implant (ABI). The animals were randomly assigned to one of the following groups: Group 1 - control (n=11) and Group 2 - intermittent cigarette smoke inhalation (n=11). Sixty days after surgery, the animals were sacrificed. The degree of bone-to-implant contact (BIC), bone filling (BF) within the limits of the threads of the implants and bone density (proportion of mineralized bone in a 500-mu m-wide zone lateral to the implant - BD) were measured in the cortical (zone A) and cancellous bone (zone B) areas. Data analysis showed ...

A dental implant (also known as an endosseous implant or fixture) 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. The basis for modern dental implants is a biologic process called osseointegration where materials, such as titanium, form an intimate bond to bone. The implant fixture is first placed, so that it is likely to osseointegrate, then a dental prosthetic is added. A variable amount of healing time is required for osseointegration before either the dental prosthetic (a tooth, bridge or denture) is attached to the implant or an abutment is placed which will hold a dental prosthetic.. Success or failure of implants depends on the health of the person receiving it, drugs which impact the chances of osseointegration and the health of the tissues in the mouth. The amount of stress that will be put on the implant and fixture during normal function is ...

Nowadays, numerous internal bone remodelling concepts are under development, in order to estimate long-term functionality of implants by evaluating the intensity of stress-shielding effect. This effect is also analysed for the implants for direct skeletal attachment, considered as a better exoprosthesis fixation method than prosthetic sockets. Most of bone remodelling approaches are based on basic concepts, differing with certain assumptions, which may affect the accuracy of the results. This article compares commonly used internal bone remodelling concepts and evaluates the functionality of the proposed Limb Prosthesis Osseointegrated Fixation System for direct skeletal attachment of limb prosthesis in comparison with two currently available implants: the Intraosseous Transcutaneous Amputation Prosthesis and the Osseointegrated Prostheses for the Rehabilitation of Amputees ...
Background: The increasing incidence of prosthesis revision surgery in the Western world has led to an increased focus on the capacity for stem removal. We previously reported on a femoral stem implanted in goats with an approximate 15% reduction in retention force by drilling longitudinally orientated grooves on the side of the stem. In this current study, we aimed to histologically evaluate the bony apposition towards this stem and correlate this apposition with the pullout force. Methods: We analyzed the femora of 22 goats after stem removal. All stems remained in place for 6 months, and the goats were allowed regular loading of the hip during this time. For histological evaluation, all femora were immersed in EDTA and decalcified until sufficiently soft for standard technique preparation. We evaluated bone apposition, the presence of foreign particle debris and other factors. The apposition was evaluated with a scoring system based on semi-quantitative bone apposition in four quadrants. ...
Purpose: To investigate osseointegration of oral implants, which were retrieved from a patient after 29 years in situ, we use novel three-dimensional analysis methods and visualization techniques that supplement conventional two-dimensional analysis. Materials and Methods: The sample processing involved nondecalcification and embedment in resin. Conventional two-dimensional histomorphometrical methods were conducted. Additionally, the quantification was extended to three-dimensional by using synchrotron radiation micro-computed tomography (SRmCT) technique and two relevant visualization methods for the three-dimensional data were introduced. Results: The three-dimensional results involved three-dimensional quantification and visualization of two implant samples with methods beyond state-of-the-art. Traditional two-dimensional histomorphometrical results revealed a mean bone-implant contact (BIC) of about 50%. In most samples, bone area (BA) was lower inside the treads compared with out-folded ...
BACKGROUND: The concept of osseointegration involves direct contact between titanium implant and bone. This transcutaneous prosthetic system for amputees is intended to assure stable long-term fixation. Most metal transcutaneous implants have failed, primarily owing to infection. QUESTIONS/PURPOSES: We determined the frequency and describe the presentation of infectious complications with this novel method. We also evaluated the bacterial flora at the skin-penetration area and its relation to the development of local and implant-related infection. PATIENTS AND METHODS: We prospectively followed 39 patients with arm and leg amputations fitted with transcutaneous osseointegrated titanium implants a mean of 56 months earlier (range, 132-133 months). There were 33 femoral, one tibial, four ulnar, four radial, and three humeral implants. Patients were selected during a 6-month period in 2005 and identically reevaluated after 3 years. Implant infection was defined as definite, probable, or possible ...
Percutaneous osseointegrated (OI) implants for direct skeletal attachment of upper extremity prosthetics represent an alternative to traditional socket suspension that may yield improved patient function and satisfaction. This is especially true in high-level, transhumeral amputees where prosthetic fitting is challenging and abandonment rates remain high. However, maintaining mechanical integrity of the bone-implant interface is crucial for safe clinical introduction of this technology. The collection of population data on the transhumeral loading environment will aid in the design of compliance and overload protection devices that mitigate the risk of periprosthetic fracture ...
A technique to enhance the stability of dental and orthopedic implants (including artificial joints and fractures) by inducing implant micromotion via a permanent magnet coupled to the implant which is vibrated using a cyclic magnetic force to enhance growth and apposition of the surrounding bone. In the preferred embodiment the implant temporarily holds a rigidly fixed, permanent magnet that is oscillated by an externally applied, time varying moving magnetic field of controlled frequency and intensity. Movement of the internal magnet transmits movement to the implant and effects stimulation of the implant-bone interface.

Results: Healing was generally uneventful. A removal torque analysis showed significantly higher mean (± SE) peak values for the control implants than for the test implants at 2 weeks (31.4 ± 2.5 Ncm versus 20.4 ± 1.8 Ncm) and 4 weeks (48.4 ± 5.5 Ncm versus 30.3 ± 3.9 Ncm). Light microscopy showed no significant differences in local bone density around control and test implants at 2 and 4 weeks (range, 85% to 91% within the thread area and 91% to 95% immediately outside the threads). At 2 weeks, bone-implant contact for control and test implants averaged 81.8% ± 2.8% and 75.7% ± 4.6%, respectively, and at 4 weeks the bone-implant contact values were 79.4% ± 2.8% and 73.5% ± 4.2%, respectively; these differences were not significant. Backscatter scanning electron microscopy also showed no significant differences in local bone density at control and test implants at 2 and 4 weeks (range, 55% to 72% within the thread area and 75% to 81% immediately outside the threads). At 2 weeks, ...

The implant was designed by EIT Emerging Implant Technologies GmbH, a newly formed company that is dedicated to 3D-printed implant solutions. EIT partnered with 3D Systems in the 3D design and manufacturing process.. This additive manufacturing method allows the material to mimic the trabecular bone structure. EIT cellular Titanium with micro-, macro- and nanostructural features provides high stability and speeds up the bone healing and fusion process. It provides an optimal biomechanical and biological environment for natural bone ingrowth without the need to add bone graft. The individualisation fits exactly to the patients individual anatomy.. The goal of the individualisation of a series implants is to reduce typical implant-related complications such as migration, subsidence or delayed fusion, all of which are related to insufficient bone-implant contact of standard implants.. Spetzger said, We are fascinated by the possibilities of this new technology combining modern computer-aided ...
Orthopedic implants often loosen due to the invasion of fibrous tissue. The aim of this study was to devise a novel implant surface that would speed healing adjacent to the surface, and create a stable interface for bone integration, by using a chemoattractant for bone precursor cells, and by controlling tissue migration at implant surfaces via specific surface microgeometry design. Experimental surfaces were tested in a canine implantable chamber that simulates the intramedullary bone response around total joint implants. Titanium and alloy surfaces were prepared with specific microgeometries, designed to optimize tissue attachment and control fibrous encapsulation. TGFß, a mitogen and chemoattractant (Hunziker EB, Rosenberg LC. J Bone Joint Surg Am 1996;78:721-733) for osteoprogenitor cells, was used to recruit progenitor cells to the implant surface and to enhance their proliferation. Calcium sulfate hemihydrate (CS) was the delivery vehicle for TGFß; CS resorbs rapidly and appears to be ...
Percutaneous fixation implants anchor a prosthesis to a selected bone, which increases mobility, but can cause infection, skin regression, and early implant failure. Such complications require surgery to replace the implant and involve long recovery periods that reduce the quality of life for amputees. The Modular Osseointegrated, Porous-coated Prosthetic Abutment System (MOPPAS) alleviates complications associated…

Since the 1980s, hydroxyapatite (Ca10(PO4)6(OH)2; HA) has been used as a coating material for orthopaedic implant applications owing to its bioactivity and similarity in composition to bone mineral (Constantz et al. 1995). It was found to be capable of supporting bone ingrowth and osseointegration (Hench 1998). Therefore, it had significant success in strengthening the fixation between the implant and bone tissue, thus reducing the healing period during orthopaedic implantation practice (Oonishi 1991).. However, in addition to surface chemistry, a number of studies have shown that the surface topography can be another significant factor in influencing the initial cellular response and therefore subsequent bone tissue regeneration (Curtis & Wilkinson 1997). The work of Britland et al. (1996) compared a chemical cue (laminin) oriented at right angles with a topographic factor. When the grooves were ,500 nm deep, the cells reacted mainly with the chemical cue. When deeper grooves were present, the ...
The new implant system uses a titanium implant connected directly into the bone of the arm, as part of a process called osseointegration. This creates a long-term stable fusion between the patient and their implant, which Dr. Ortiz-Catalan explains in detail:. The artificial arm is directly attached to the skeleton, thus providing mechanical stability. Then the humans biological control system, that is nerves and muscles, is also interfaced to the machines control system via neuromuscular electrodes. This creates an intimate union between the body and the machine; between biology and mechatronics.. Connecting electrodes directly to the nerves and muscles means that patients can control their prosthesis more easily and with greater precision, enabling them to handle smaller and more delicate items.. Due to the close proximity between the electrodes and the nerves controlling the device, activity from other muscles is prevented from interfering with the device, allowing the patient to move the ...

Patients with hopeless dentition often present difficulties in the management of the transitional phase to the final restoration. This article describes a staged approach to achieve a full-arch, implant-supported, removable prosthesis in patients with a hopeless dentition. The approach described allows the clinician to proceed in a staged manner and facilitate prosthetic steps by keeping fixed references for vertical dimension. This technique includes initial conservative periodontal care and, afterward, extraction of some strategic teeth, while others are temporarily maintained. At this point, the implants are positioned, and during the healing period, the remaining natural abutments are used for occlusal reference and to stabilize the removable provisional prosthesis. After osseointegration of the implants, the residual teeth are extracted and the final prosthesis is delivered. The main advantages of the technique include maintenance of function during treatment, stabilization of the removable ...
The satisfactory positioning of an implant during dental surgery is essential to the success of the treatment. However, accidents can occur during the period of osseointegration, leading to implant movements that hinder or may even prevent prosthetic rehabilitation. Implants can be repositioned through sandwich osteotomy, which has been labeled a versatile, viable and predictable technique in the literature. The aim of the present study was to report a case involving the esthetic displacement of an implant, caused by a sports accident, which was repositioned using sandwich osteotomy, with the interposition of lyophilized bovine bone between the osteotomized segments. In order to adequately perform this repositioning, the authors devised a guide to assist with the positioning process ...
