Bone regeneration in 2 stages for retention of dental implant. A case report.

This case report describes the successful rebuilding of jaw bone for t he anchorage of an endosseous implant by applying the principle of "guided tissue regeneration". The extremely reduced bone volume required reconstructive surgery in 2 stages, the 1st surgical procedure being carried out before the installation of the implant and the 2nd simultaneously with the placement of the implant. The biological prerequisites as well as technical demands for this treatment modality are discussed.
