Partial edentulism in 34 patients was consecutively treated using the Brånemark osseointegration technique. A total of 102 implants was tested for mobility, signs and symptoms of infection, and radiographic bone levels. All patients had at least a 6-month follow-up of prosthesis function (mean 22.5 months). An overall success rate of 88.2% was observed. Twenty-five of 28 maxillary implants and 65 of 74 mandibular implants were successfully placed and restored. Twelve failures; were observed; 7 were not integrated at the time of stage 2 surgery while 5 occurred after prosthetic reconstruction. The results of this study suggest that the Brånemark osseointegration procedure can be used to treat partially edentulous patients with a high degree of success.
