Abstract PURPOSE: This multicenter investigation is an interim 3-year survival report of a 5-year prospective study using Brånemark osseointegrated implants in partially edentulous patients. MATERIALS AND METHODS: Previously defined patient characteristics and clinical parameters were related to implant survival using lifetable analysis. RESULTS: Three years after prosthesis insertion, 460 implants placed in 139 patients remained in the study. Cumulative success rates for maxillary implants (92.5\%) were less than for mandibular implants (94.8\%), with an overall cumulative success rate of 93.9\%. CONCLUSION: Failures were associated with poor bone quality, smaller implant sizes, and a higher plaque index, and were more likely to occur before loading. A 4\% incidence of residual long-term inferior alveolar nerve paresthesia was higher than previously reported.
