摘　　要：目的比较椅旁CAD/CAM玻璃瓷嵌体与复合树脂充填治疗牙楔状缺损的疗效。方法研究选取进行治疗的牙楔状缺损患者40例,分为玻璃瓷组20例(椅旁CAD/CAM玻璃瓷嵌体组)和树脂组20例(光固化复合树脂组),2年后观察比较并统计2组患者的牙体修复情况。结果玻璃瓷组20例患者中出现继发龋1例,复合树脂组20例患者中出现继发龋6例,差异有统计学意义(P<0.05);玻璃瓷组20例患者中出现楔状缺损1例,复合树脂组20例患者中出现楔状缺损7例,差异有统计学意义(P<0.05);玻璃瓷组20例患者中出现牙髓炎1例,复合树脂组20例患者中出现牙髓炎6例,差异有统计学意义(P<0.05)。结论椅旁CAD/CAM玻璃瓷嵌体修复牙楔状缺损较复合树脂不易出现继发龋、牙髓炎和再次发生楔状缺损。Objective To compare the curative of filling wedge - shaped defect by glass ceramic inlay made by CEREC CAD/ CAM and composite resin. Methods 20 patients of Yinchuan Stomatological Hospital with wedge - shaped defect were selected. Patients were randomly assigned to the glass ceramic group or the composite resin group. After 24 months, the dental restorative condition were ob- served and analyzed. Results Secondary caries occurred in one case of glass ceramic group, and it occurred in 7 cases of composite resin group （ P 〈 0.05 ）. New wedge - shaped defect occurred in one case of glass ceramic group, and it occurred in 8 cases of composite resin group （P 〈 0.05 ）. Pulpitis occurred in one case of glass ceramic group, and it occurred in 7 cases of composite resin group（P 〈 0.05 ）. Conclusion The curative effect of glass ceramic inlay by CEREC CAD/CAM are better than composite resin.
