The purpose of the study was to evaluate 12 posterior composite resins with a standard clinical placement technique that could be followed in a practice setting. Important points stressed are the use of rubber dam, care taken to detail on manufacturer's directions, incremental placement technique, and a standard finishing technique. Sixty‐one Class II restorations were placed by a single operator. All of the restorations were evaluated at baseline, one and three years using the modified Ryge criteria. Indirect evaluation of wear was completed for each restoration using Lein‐felder's technique. Two percent of the restorations at 1 year and 17 percent at 3 years were not clinically acceptable.
