“…This allows enhanced glenoid bone tissue response to the implant surface and promotes bone ingrowth and osseous conduction processes. 28 The mesh is designed with a pore size that more closely resembles host cancellous bone, allowing a press fit and mechanical interlock to develop through a greater friction coefficient. This also further reduces the degree of micro motion at this level, thereby reducing likelihood of radiolucencies.…”

Short-term rates of radiolucency after primary total shoulder arthroplasty using a cementless metal-backed pegged polyethylene glenoid

et al. 2018

Background: Total shoulder arthroplasty has shown good clinical efficacy in treating primary and secondary degenerative conditions of the glenohumeral joint. Glenoid loosening, however, remains the commonest cause of failure. The purpose of this study was to investigate the rate of radiographic periprosthetic lucency associated with the use of an uncemented, pegged, metal-backed polyethylene glenoid component. Materials and methods: A retrospective, single-centre study using the Epoca (Synthes, Paoli, Pennsylvania) metalbacked glenoid component. Operations were performed by two experienced consultant upper limb surgeons. Radiographs were analysed for immediate post-operative component seating and periprosthetic radiolucent lines at predefined regular post-operative intervals. Intra-and inter-observer reliability was assessed to improve validity of results. Results: Mean age and follow-up was 72 (48-91) years and 2.5 years (2-5), respectively. Main indications for total shoulder arthroplasty were primary osteoarthritis, rheumatoid arthritis, revision for failed hemi-arthroplasty and acute fracture. Ninety-six per cent of components were completely seated post-operatively. Fifty-four (95%) of the 57 shoulders had no periprosthetic radiolucent lines at most recent follow-up. Complete post-operative glenoid seating was significantly associated with the absence of later periprosthetic radiolucency (p < 0.01). Conclusion: This study reports low early radiolucency rates with the pegged, uncemented, metal-backed polyethylene glenoid prosthesis used. Excellent post-operative glenoid seating is associated with a significantly lower rate of radiolucency. Longer follow-up data are required to confirm these early promising results. Level of evidence: Therapeutic, level IV.

“…An aluminum oxide coating substrates showed improvement in corrosion resistance compared to uncoated titanium substrates (6) .Ceramic materials such as alumina, partially stabilized zirconia, and titania possess high wear resistance, mechanical strength, and good biocompatibility (7) . When preparing implant sockets, the infection or trauma to the alveolar bone appears to be one of the causative factor of early implant losses (8) , so researchers are increasingly focusing on the development of the antibacterial property of implants (9) .…”

Background: Even the wide use of dental implants, still there is a proportion of implants are failed due to infection. Much considerable attention has been paid to modify the implant surface. Coating of dental implant with a biocomposite material of suitable properties can improve osseointegration. And this is the main concern of this study. The aim of present study was to evaluate the use of a biocomposite coating of dental implant with (ceramic nano Al2O3 and metalic AgNo3) on the bond strength at bone-implant interface and tissue reaction. Materials and methods: A total number of forty-eight screws, CpTi dental implant used in this study. Half of these screws were coated with a biocomposite material of nano (Al2O3and AgNo3), this was done by using electrophoretic deposition method (EFD). In invitro part of the study, analysis of the coated surface was done using: X ray diffraction (XRD), atomic force microscope (AFM), Energy Dispersive X-ray spectroscopy (EDX), Optical microscopy and Scanning electron microscope (SEM). In invivo part of study, 10 white male New Zealand rabbits were used, and a screw type of dental implant [uncoated and coated with nano (Al2O3and AgNo3)] were implanted in each tibia of rabbit. Then biomechanical and Histological test were performed after 2 and 4 weeks healing intervals. Results: The results of biomechanical test showed a higher torque mean values of (M+SD):(14.91N.cm+2.7)and (22.5 N.cm +5.31) after 2 and 4 weeks respectively. In histological examination of coated screws at 2 weeks, there isa bone trabeculae occupies a base of implant bed with osteoblast andosteocyte. At 4 weeks, there is a progress in the healing process around dental implant, and this includes:-new bone with haversian canals, osteoblast and osteocyte. Conclusion: Biocomposite coating of dental implant with Alumina and silver nitrate can be made by electrophoretic deposition method (EPD), and a multifunctional surface has been created.

Long-term and stable fixation of implants is one of the most important points for a successful orthopedic surgery in the field of endoprosthesis. Osseointegration (OI), functional connection between bone and implants, is considered as a pivotal process of cementless implant fixation and integration, respectively. OI is affected by various factors of which the property of implants is of high significance. The modification of implants surface for better OI has raised increasing attention in modern orthopedic medicine. Here, the process of OI and the interactions between implants and ambient bone tissues were emblazed. The knowledge regarding the contemporary surface modification strategies was systematically analyzed and reviewed, including materials used for the fabrication of implants, advanced modification techniques, and key factors in the design of porous implants structure. We discussed the superiority of current surface modification programs and concluded that the problems remain to be solved. The primary intention of this systematic review is to provide comprehensive reference information and an extensive overview for better fabrication and design of orthopedic implants.
