Six years' experience with Brånemark osseointegrated implants.

Over 6 years of the implant programme in the University of Otago School of Dentistry, the rate of use of osseointegrated implants to support or retain a dental prosthesis has increased. This increased use has been most marked in young adults who have required the restoration of a single space in the anterior maxillae. The treatment outcome is unequivocally positive, with an overall fixture retention rate of over 99 percent.
