title: Surgical correction of malpositioned implants. A case report.
abstract: A new technique for surgical correction of malpositioned implants is described. A 64-year-old female got her first fixed prosthesis anchored to 6 Brånemark implants in her upper jaw, in April 1993. The implants were poorly positioned and despite great efforts to make the construction aesthetically acceptable, the patient did not approve. In order to obtain better aesthetics, it was decided to move some of the osseointegrated implants to other positions. With a trephine drill, fixtures were removed including the surrounding bone, and 2 of them were placed in new sites made with the same drill. After a healing period of 6 months, abutments were connected and a new fixed prosthesis was made. After 1 year of loading, all implants were still stable. A marginal bone resorption to the 3rd thread was found around one of the implants.
