Abstract
The single-tooth implant restoration appears to be an ideal method of replacing missing natural teeth in a healthy dentition. Most follow-up studies report a high success rate. The restoration is seen by many clinicians as a relatively straightforward technique easily adapted to general dental practice and popular with patients, although it is not without complications. The purpose of this paper is to look at common problems following the placement of root-formed endosseous dental implants. A number of implant systems are reviewed and the results of the authors' clinical experiences reported.
