摘　　要：目的:观察IPS e.max.CAD瓷块与复合树脂高嵌体修复大面积缺损后牙的疗效及安全性。方法:选取2018年1月-2018年9月笔者医院口腔科诊治的82例后牙大面积缺损患者为研究对象,根据非随机临床同期对照研究及患者自愿原则分为瓷块组(n=41)、复合树脂组(n=41),其中瓷块组接受IPS e.max.CAD瓷块高嵌体修复,而复合树脂组进行复合树脂高嵌体修复,修复体均粘接12个月进行复诊,比较两组修复效果、患者满意度及不良反应发生情况。结果:瓷块组修复体形态、修复体颜色、边缘颜色、边缘密合度及继发龋的分级相较于复合树脂组明显优,差异有统计学意义(P<0.05);瓷块组患者满意度明显高于复合树脂组,差异有统计学意义(P<0.05);两组总不良反应发生率比较,无显著性差异(P>0.05),但与复合树脂组比较,瓷块组对颌牙磨耗、牙龈炎发生率略高(P>0.05)。结论:与复合树脂高嵌体相比较,IPS e.max.CAD瓷块高嵌体对大面积缺损后牙的修复效果明显优,但后者修复期间更易出现对颌牙磨损及牙龈炎,IPS e.max.CAD瓷块高嵌体修复或许更适于对美学效果要求较高且牙周状况较好的患者。Objective To observe the effects and safety of IPS e.max.CAD ceramic blocks and composite resin onlay in repair of massive defect of posterior teeth.Methods Eighty-two patients with massive defect of posterior teeth diagnosed and treated in stomatology department of the hospital between January and September 2018 were selected as the subjects.They were divided into the ceramic block group(n=41)and the composite resin group(n=41)according to the principle of non-randomized clinical concurrent control trial and voluntariness.The ceramic block group was treated with IPS e.max.CAD ceramic block onlay while the composite resin group was treated with composite resin onlay.The restorations were bonded for 12 months and reexamined.The effect of repair,patients’satisfaction and adverse reactions were compared between the two groups.Results The morphology and color of restorations,color of the margin,margin fitness and the grade of secondary caries in the ceramic block group were significantly better than those in the composite resin group(P<0.05).The satisfaction of patients in the ceramic block group was significantly higher than that of the composite resin group(P<0.05).There was no significant difference in the total incidence of adverse reactions between the two groups(P>0.05).However,the incidence rates of wear of paired jaw teeth and gingivitis in the ceramic block group were slightly higher than those in the composite resin group(P>0.05).Conclusion Compared with composite resin onlays,the effect of IPS e.max.CAD ceramic block onlay is obviously better in repair of massive defect of posterior teeth.However,wear of paired jaw teeth and gingivitis are prone to occur during the latter repair.IPS e.max.CAD ceramic block onlay restoration may be more suitable for patients having higher aesthetic requirements and better periodontal conditions.
