BACKGROUND Numerous studies have shown the superiority of platform-switched implants in preserving crestal bone as compared with platform-matched implants. However, the influence of initial soft tissue thickness on development of crestal bone loss has not been addressed in previous studies; thus, further research is needed. PURPOSE To evaluate crestal bone levels around platform-switched impl...

PURPOSE The aim of this paper was to distinguish what kind of mucosal tissue, measured at the top of the crest can be referred to as thin, medium or thick and its influence on crestal bone loss around dental implants after a 1-year follow-up. MATERIALS AND METHODS Totally 64 implants were evaluated in 26 patients. 32 implants (test group) were placed about 2 mm supracrestally and 32 implants ...

Purpose: The long-term success of an implant depends on the stability of bone support for the implant. Most crestal bone loss occurs in the first year of implant placement. Platform-switching is an approach which can be clinically applied to preserve the crestal bone. The concept of ‘platform switching’ refers to the use of a smaller-diameter abutment on a larger-diameter implant collar. The pu...

Following the exposure and restoration of two-piece dental implants, some change in the vertical level of the peri-implant crestal bone height has been reported. This change in crestal bone height has not, however, negatively impacted long-term implant success. This article describes how the concept of platform switching is incorporated into a new implant design as a means of reducing or elimin...

Aim: The purpose of the study was to evaluate the changes in peri-implant bone quality, crestal bone level and the implant stability (periotest) for mandibular implant retained overdentures with ball attachments using delayed and immediate loading protocols. Materials and methods: Two Alpha-Bio dental implants were placed in the anterior part of the mandible in ten completely edentulous patient...

OBJECTIVE Crestal bone loss is a biological complication in implant dentistry. The aim of this study was to compare the effect of progressive and conventional loading on crestal bone height and bone density around single osseointegrated implants in the posterior maxilla by a longitudinal radiographic assessment technique. MATERIALS AND METHODS Twenty micro thread implants were placed in 10 pa...

Purpose: Implant length, implant surface area, and crown-to-root (c/r) ratio and their relationship to crestal bone levels were analyzed in 2 groups of partially edentulous patients treated with sintered porous-surfaced dental implants. Materials and Methods: One hundred ninety-nine implants were used to restore 74 partially edentulous patients with fixed prostheses. Implants were categorized a...

BACKGROUND Experimental studies demonstrated that peri-implant crestal hard and soft tissues are significantly influenced in their apico-coronal position by the rough/smooth implant border as well as the microgap/ interface between implant and abutment/restoration. The aim of this study was to evaluate radiographically the crestal bone level changes around two types of implants, one with a 2.8 ...
