The Influence of the Usage of a Trephine Bar for Dental Implant Placement

Abstract

5 INTRODUCTION The sufficient integration of bone and the dental implant surface, or osseointegration, is critical in dental implant treatment. The use of the appropriate drill is important for achieving clinically sufficient osseointegration. Recently, we tried to use a trephine bar for the first drilling in dental implant placement. However, no previous report has evaluated the influence of the usage of a trephine bar for dental implant placement. The usage of a trephine bar for drilling enables the histological diagnosis of bone quality and the addition of the removed bone to cover deficient bone around the implant. In the present study, we evaluated the clinical results for dental implants placed with a trephine bar compared with those for dental implants placed with a regular drill.
