Abstract
Objective: To systematically review clinical studies on the performance of implant-supported single-tooth restorations (STR).
Data sources: Medline 1990–1998, using keywords, ‘dental in SB’, ‘implant’ and ‘single’.
Study selection: Only English papers that met a strict three-level selection procedure, including availability of or the ability to calculate life-table survival curves, were included.
Data extraction and synthesis Cumulative life-table survival curves were constructed by pooling data from the included studies to new data sets.
Results: Of 332 papers initially identified, the majority were excluded because they were case reports, technical notes or descriptions of clinical procedures. Nine studies met all the criteria with the data predicting a 97%(±1%) survival implant survival at 4 years, with an uncomplicated crown survival rate of 83%(±3%).
Conclusions: Single tooth implants have an acceptable short-term survival rate. More information and better quality clinical studies and reporting are needed, however.
