STATEMENT OF PROBLEM The need for tooth replacement in individuals with Down syndrome (DS) is explained by the high prevalence of dental agenesis and by the premature loss of teeth through severe periodontal disease. Dental implants may be the dental procedure of choice in some of these patients. PURPOSE The purpose of this clinical study was to analyze dental implant survival in a series of ...

Ninety-seven revisions of total hip replacements are reviewed with a median time of observation of 47 months. Satisfactory pain relief was obtained in 86%. There were six complete failures which were reduced to three by further surgery. One hip became infected and was excised. In 12 cases the revisions were complicated by peroperative fractures and in five by dislocations. Radiographic analysis...

Patellofemoral arthroplasty (PFA) has been an option for patients with symptomatic patellofemoral osteoarthritis since the 1950's. Many of the early failures resulted from a combination of implant design and surgeon technique. The goal of this overview is not to review the history of PFA, but rather to explore options for surgeons to optimize long-term outcomes and improve patient knee function...

BACKGROUND Implants may be placed penetrating the oral mucosa (1-stage procedure) or can be completely buried under the oral mucosa (2-stage procedure) during the healing phase of the bone at the implant surface. With a 2-stage procedure the risk of having unwanted loading onto the implants is minimized, but a second minor surgical intervention is needed to connect the healing abutments and mor...

Total Joint Replacements (TJR) have been extremely successful over the past 50 years, restoring mobility and function to millions of people each year. However, over time these implants need replacing for a number of reasons, such as infection or increasing immune reactivity to implant debris. All implant metals degrade in vivo, and the released products biologically interact locally and systemi...

PURPOSE To evaluate the safety and clinical efficacy of a novel surface treatment (SurfLink®, Nano Bridging Molecules, Gland, Switzerland) on titanium dental implants. SurfLink consists of a monolayer of permanently bound multi-phosphonic acid molecules, which mimics the surface of naturally occurring hydroxyapatite. MATERIALS AND METHODS Twenty-three patients requiring at least two single de...

BACKGROUND Due to increasing demands for a full mouth implant reconstructions and the fact that the most failures are associated with biomechanical complications, determining the effect of different occlusal patterns on these complications seems inevitable. The aim of this study is to compare affection of different occlusal designs in full mouth implant reconstructed patients on electromyograph...

PURPOSE The aim of this study was to measure the peri-implant bone length surrounding implants that penetrate the sinus membrane at the posterior maxilla and to evaluate the survival rate of these implants. METHODS Treatment records and orthopantomographs of 39 patients were reviewed and analyzed. The patients had partial edentulism at the posterior maxilla and limited vertical bone height be...
