摘　　要：目的:研究间接树脂嵌体修复和复合树脂直接充填磨牙大面积牙体缺损在老年患者中的临床疗效。方法:选择184例老年患者,将符合纳入标准的200颗患牙随机分为2组,分别以硬质树脂嵌体及复合树脂充填修复牙体外形。随访3年,参考美国公共健康会(USPHS)标准,对其临床效果进行观察。结果:2种方法在色泽匹配、边缘着色、龈指标、磨损程度及继发龋方面无统计学差异(P>0.05);在邻接关系、边缘完整性及修复体折裂方面具有统计学意义(P<0.05)。结论:硬树脂嵌体修复比复合树脂充填能更好地恢复老年患者磨牙正常邻接关系,防止食物嵌塞,保持牙周组织健康。Objective：To evaluate the clinical effect of indirect compos -item resin inlay and composite resin in treatment for badly broken down molars of the older. Methods： 184 old patients with 200 badly broken- down molar were selected and divided into test group （restored by indirect composite resin inlays ） and control group （restored by compos -ite resin ）. All the patients were followed up for 3 years and the clinical effects of two groups were compared following USPHS criterion. Results： In tow groups, there was no significant difference in color matching ,marginal discoloration, secondary caries, and et cetera （P〉 0.05）, and there was significant difference in marginal adaption, anatomic shape integrity and fractures of tooth （P〈 0.05）. Conclusions： Massive destruction in molar can be well restored with the indirect composite resin inlay, clinical effects of which are superior to those of composite resin in elders.
