Abstract
Objective To assess the survival of implants supporting fixed partial dentures and single crowns in partially edentulous patients.
Data Sources MEDLINE 1980–1996 using terms, dental implants, cylindrical intraosseous, osseo-integration, edentulous, partial, single, fixed bridges, fixed partial dentures, prosthodontic treatment, survival. In addition reference lists of collected papers were searched. Only papers published in English or with English abstracts were included.
Study selection Studies were included which reported on cylindrical metallic threaded intraosseous implants, had a minimal follow-up period of 1 year, implant failure was defined and cumulative survival rate could be calculated. Where multiple reports used the same implants only the most recent data was used.
Data extraction and synthesis A life-table actuarial analysis was performed for each study and for pooled data on implants from single crown and fixed partial denture groups.
Results 66 studies were identified. Nine studies on single crown (SC) supporting implants, 9 on implants supporting fixed partial dentures (FPD) and one reporting on both SC and FPD were included (19 in all). The included studies totalled 2686 implants 570 supporting SC and 2116 supporting FPDs.
Conclusion The cumulative survival rate for implants supporting fixed partial dentures and single crowns in partially edentulous jaws was found to be over 90%.
