The McGill consensus statement on overdentures.

On May 24-25, 2002, a symposium was held at McGill University in Montreal, Quebec, Canada, during which scientists and expert clinicians presented 75 papers on the efficacy of overdentures for the treatment of edentulous patients. Strong emphasis was given to evidence from randomized controlled trials in which mandibular two-implant overdentures were compared to conventional dentures. A draft consensus statement was circulated to all presenters, as well as to subjects who participated in some of the clinical trials and other edentulous individuals who attended the symposium. The statoment was modified during the meeting in tight of their comments. We hope that the final version of the consensus statement will serve as a guideline for ctinioians and patients, and that it will stimulate discussion within and between professional organizations, heaith authorities, and thirdparty payers.
