Histological analysis of the biological width surrounding primate teeth offers insights into why the blood supply is reduced after tooth extraction and implant placement. This occurs because of the reduction of ridge width and height. The reduction in blood supply tends to be exacerbated as development of a new biologic width after implant placement causes facial bone to be lost both vertically...

BACKGROUND The failure of the host tissue to establish or maintain osseointegration around dental implants is due to either occlusal or parafunctional forces, premature loading, ill-directed stress, or microbial infection. The long-term failure rate of dental implants is generally 5-10%. Although a variety of etiologies of early peri-implant bone loss (from implant placement to 1-year post-load...

OBJECTIVES Placing implants in the posterior maxillary area has the drawback of working with scarce, poor quality bone in a significant percentage of cases. Numerous advanced surgical techniques have been developed to overcome the difficulties associated with these limitations. Subsequent to reports on the elevation of the maxillary sinus through the lateral approach, there were reports on the ...

PURPOSE The purpose of this study was to evaluate the clinical outcomes of patients undergoing sinus membrane elevation by a minimally invasive crestal approach using a novel drilling system. MATERIALS AND METHODS From May 2008 to November 2009, 21 implants were placed in 19 patients (10 men and 9 women) ranging from 23 to 69 years of age (average of 49.5 years). Implants were placed in maxil...

Older adults are expected to account for an increasingly disproportionate number of individuals needing oral implant prostheses. However, this biotechnology was initially studied for predominantly middle-aged edentulous patients, not elderly people. High rates of success and minimal crestal bone loss have been reported for oral implants mainly in this group. The results of studies at the Univer...

Generally, endosseous implants can be placed according to a nonsubmerged or a submerged technique and in 1-piece or 2-piece configurations. Recently, it has been shown that peri-implant crestal bone reactions differ significantly radiographically as well as histometrically under such conditions and are dependent on a rough/smooth implant border in 1-piece implants and on the location of a micro...

background: the success of dental implants depends on the manner in which stresses are transferred to the surrounding bone. an important consideration is to design an implant with a geometry that will minimize the peak bone stresses caused by standard loading. the aim of this study was to assess the infl uence of implant thread geometry on biomechanical load transfer and to compare the differen...
