title: Implant survival rates in partially edentulous patients: a 3-year prospective multicenter study.
abstract: OBJECTIVE
  This multicenter investigation is an interim 3-year survival report of a 5-year prospective study using Brånemark osseointegrated implants in partially edentulous patients.
  
  
  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%.
  
  
  CONCLUSIONS
  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.
