Dental implant retrieval analyses

The evolution of surgical implant devices has been dependent upon a multidisciplinary coordination between the basic and applied biological and physical sciences. In this regard, engineering failure analyses of retrieved prostheses represent a significant contribution. Dental implant retrieval studies have provided guidance for biomaterials, designs and biomechanical function, specialized surface treatments for controlling tissue responses, and associated surgical, periodontal, and restorative regimes. The recent expansion of design concepts and restorative procedures places a new emphasis on the need for interrelated prospective laboratory, laboratory animal, and human device investigations. Retrospective retrieval analyses continue to provide guidance with regard to key concept development and the formulation of important questions and hypotheses for future investigations.
