An artificial joint (prosthesis) helps reduce pain and improve function. Also called total hip arthroplasty, replacement surgery might be an option if interferes with daily activities nonsurgical treatments haven't helped or are no longer effective. We review the different materials, constructions, surfaces used in development of femoral stems, order to solve avoid various problems associated t...

This study's objective was to identify, in a statistically valid and efficient manner, the risk factors associated with dental implant failure. We hypothesize that factors exist which can be modified by clinicians to enhance outcome. A retrospective cohort study design was used. Cohort members had >or= one implant placed. Risk factors were classified as demographic, health status, implant-, ana...

The study of dental implant surfaces is relevant in order to better understand the interaction of the titanium surface and the surrounding tissues. Clinical success is achieved not only because of implant material but also because of other properties as implant design, surface treatment and quality. In this work, we report a detailed surface investigation of three major Brazilian made implants ...

We describe the Molteno3 glaucoma implant, its design principles and the differences and similarities with the current generation of Molteno implant. Clinical results from 37 Molteno3 implant procedures for primary open angle glaucoma are compared with a control group of 33 pressureridge single plate Molteno implants. The results obtained in cases of primary open angle glaucoma, neovascular gla...

Predictable retrievability of cement-retained prostheses has been a clinical concern. This article presents a technique that describes an implant restoration design which will allow predictable removal of cement-retained implant-supported prostheses.

Purpose. The purpose of this finite element study was to compare stresses, strains, and displacements of double versus single implant, in immediate loading for replacing mandibular molar. Materials and Methods. Two 3D FEM models were made to simulate implant designs. The first model used 6 mm wide-diameter implant to support a single molar crown. The second model used 3.75-3.75 double implant d...

One of the most successful techniques in restoration of degenerated joint functions is total hip replacement. This surgical approach includes removal of diseased cartilage and bone parts, and replacement by the corresponding joint prostheses. By using metal alloys, high quality plastic and polymer materials, orthopedic surgeons can reconstruct hip fractures, or replace a painful, dysfunctional ...
