摘　　要：目的:比较树脂嵌体及瓷嵌体用于修复后牙缺损的临床治疗效果。方法:选择中老年患者,临床完成Ceramage树脂嵌体50个,Vita mark II瓷嵌体46个,术后即刻、1年及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种嵌体在边缘着色、边缘密合度及继发龋发生等方面差异无统计学意义(P>0.05)。在修复体折断,颜色匹配方面Ceramage硬质树脂嵌体优于Vita mark II嵌体(P<0.05),树脂嵌体成功率为95%(38/40),瓷嵌体的成功率为73.7%(28/38)。结论:树脂嵌体适用于特殊要求的中老年患者。Objective： To evaluate the clinical performance and inlays in restoring the posterior teeth.Methods： 50 posterior teeth were res tored with Ceramage inlays,and 46 posterior teeth were restored with Vita mark II inlays.All restorations were evaluated immediately,after 1 year and 3 years,according to modified USPHS parameters.Results： There was no significant difference in marginal discoloration,marginal sealability,and secondary carries between these two groups（P 0.05）.The Ceramage inlays showed a significant performance in the color matching and resisting fracture than Vita mark II inlays（P 0.05）.The achievement ratio of indirect resin inlays is 95 percent,and the achievement ratio of all-ceramic inlays is 73.7 percent.Conclusion： Indirect resin inlays can be suitable for eldlers with specifical requirement.
