The longitudinal clinical effectiveness of osseointegrated dental implants: the Toronto Study. Part II: The prosthetic results.

Forty-six patients who had shown chronic maladaptive behavior in using complete dentures were treated with osseointegrated implant-supported prostheses. Forty patients needed mandibular treatment, three patients needed treatment in the maxillae, and three required treatment in both dental arches. At the most recent data collection (4 to 9 years after surgical placement of the implants), the 49 dental arches remained successfully treated with 44 implant-supported fixed partial dentures and five implant-supported overdentures. The efficacy of the osseointegration technique in maladaptive prosthetic patients is demonstrated in this descriptive study.
