Management of Implant Screw Loosening - A Case Report

Abstract

Dental implants have been a broadly recognised treatment modality to replace missing teeth and in order to restore the oral functions. The utilisation of root form endosseous implants have increased considerably and this option has become much more sophisticated with the introduction of latest designs and concepts. Long term post placement studies have revealed that prosthetic complications, including screw loosening, screw fracture, framework and implant fracture. Abutment screw loosening is the second most cause of failure of implant supported crowns, after loss of osseointegration. This condition is mostly witnessed in single implant supported restoration. Management of screw loosening is a challenging procedure and this clinical report describes the management of an implant abutment screw loosening of lower back teeth region with minimal damage to the existing restoration making it possible to be reused.
