Objectives: To make an inventory of clinical studies on single-tooth restorations supported by implants using a systematic review procedure and to aggregate overall survival results. Data sources: Papers referring to single-tooth implants were located by a MEDLINE search 1990 to April 1998. Three hundred and twenty references were found, and they were subjected to a systematic review procedure. Study selection: A three-step inclusion/exclusion procedure was applied to identify papers that represented: good scientific practice (GSP), reported results of all patients, implants and crowns for more than 2 years, and had sufficient data to generate life-table analyses. The outcomes were ‘implant failure’ and ‘crown completion’. Nine studies survived. These data showed an overall mean GSP of 0.37 with a predicted 4 year implant survival of 97% ( n=459), and an uncomplicated crown maintenance of 83% ( n=240). Conclusion: Single-tooth implants show an acceptable short-term survival of 4 years, but crown complications are common.
