目的比较复合树脂及树脂嵌体用于修复后牙缺损的临床治疗效果.方法选择82例患者,共96颗后牙,临床完成直接树脂修复46个,树脂嵌体50个,术后即刻、1年及2年,参考改良USPHS标准,观察其临床效果.结果直接树脂修复和间接树脂嵌体修复在边缘着色、边缘密合、继发龋、耐磨性等方面差异有显著性(P＜0.05),直接树脂修复成功率为72.2％(26/36),间接树脂嵌体成功率为91.3％(42/ 46).结论树脂嵌体具有更好的边缘密合性、抗磨损和抗折裂能力,同时对牙髓的刺激更小.

Objective To evaluate the clinical performance of resin fillings and inlays in restoring the posterior teeth.Methods 46 posterior teeth were filled with composite resin directly and 50 posterior teeth were restored with indirect resin inlays.Each restoration was evaluated at baseline,after 1 year and 2 years,according to the modified USPHS criteria.Results There was significant difference in marginal discoloration,marginal integrity,secondary carries and wear-resistance between these two groups (P＜0.05).The achievement ratio of direct resin fillings was 72.2％ and the achievement ratio of indirect resin inlays was 91.3％ Conclusion Indirect resin inlays can be suitable for restorations of posterior teeth with more physical property,with less irritation or microleakage.
