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 Leinfelder's technique. Two percent of the restorations at 1 year and 17 percent at 3 years were not clinically acceptable.
该研究的目的是采用一种在实际操作中可遵循的标准临床放置技术，对12种后牙复合树脂进行评估。强调的要点包括使用橡皮障、严格按照制造商说明操作、分层放置技术以及标准的修整技术。由一名操作人员完成了61个二类洞修复体的放置。使用改良的赖格标准，在基线、一年和三年时对所有修复体进行评估。采用莱因费尔德技术对每个修复体进行磨损的间接评估。一年时2%的修复体和三年时17%的修复体在临床上不可接受。
