Methods: Prospective and retrospective studies with a mean follow-up time of at least 5 years were considered. Only publications in English in which patients had been examined clinically at the follow-up visit were included. Publications based on patients records, questionnaires or interviews were excluded. The fixed partial dentures were analysed according to success and survival risks. A successful bridge was one that remained intact without intervention throughout the observation period. A surviving bridge was one that remained in function but had required some intervention. Specific biological and technical complications such as caries, loss of vitality, periodontal disease, loss of retention, loss of vitality, tooth fractures and material fractures were also analysed. A Medline search (PubMed) from 1966 up to May 2003 was conducted together with hand searching of bibliographies from relevant articles. Results: 19 studies from an initial yield of 3,658 titles were finally selected and data was extracted independently by three reviewers. The presence of censoring over the long follow-up periods required event rates (bridge-time) to be estimated and pooled, but not all studies published sufficient data. Wherever possible 10-year risks were approximated from the pooled rates. The 10-year risk for survival for fixed partial dentures was 81.9% while that for success was 64.4%. The 10-year risk for caries and periodontitis was 5.8%. Risk for loss of retention was 4.9%, and for abutment fracture and material fractures 2% and 1% respectively. Conclusions: This systematic review analysed a total of 19 studies reporting on 3569 FPDs with a follow-up time ranging from 1-25 years. 10-year survival and success risks were 81.9% and 64.4% respectively | ||
