A prospective multicenter evaluation of 1,583 3i implants: 1- to 5-year data.

Purpose: The purpose of this prospective multicenter study was to evaluate the efficacy of 3i threaded implants for the treatment of edentulous patients in a 1- to 5-year period. This article reports the total data and global results of 3 threaded designs of 3i implants: self-tapping, ICE, and Osseotite.

Materials And Methods: A total of 1,583 implants (619 ICE, 545 Osseotite, and 419 self-tapping) were placed between 1995 and 1999 in 528 patients at 13 European clinical centers.

Conditions for success in guided bone regeneration: retrospective study on 376 implant sites.

Background: Used alone or in association with bone, guided bone regeneration is a clinically accepted method to increase the volume of bone during implant placement. Concerns about appropriate surgical techniques and the predictability of the results questions still exist. The aim of this study was to assess the conditions for success.

Clinical evaluation of guided bone regeneration at exposed parts of Brånemark dental implants with and without bone allograft.

This investigation evaluated guided bone regeneration with a polytetrafluoroethylene barrier membrane at exposed parts of Brånemark dental implants with and without concomitant use of decalcified freeze-dried bone allograft. Density of the regenerated tissue was also determined using a No. 23 probe at a pressure of 25 g and was graded from 1 to 5.

[Periodontal reconstruction using the guided tissue regeneration technique. Apropos of a case].

Different surgical techniques have been used to treat periodontal osseous defects. Periodontists were very full of hope with osseous grafts but the results were disappointing or unpredictable. A best knowledge of the biologics determinants of periodontal healing has lead to the concept of guided regeneration.
