摘　　要：目的分析聚合瓷嵌体修复活髓牙大面积牙体缺损的临床疗效及感染预防。方法选取活髓后牙大面积牙体缺损患者42例患牙48颗,随机分为实验组(24颗牙)和对照组(24颗牙)。其中实验组牙体预备,聚合瓷嵌体修复;对照组应用金属烤瓷冠修复,应用RelyX Unicem树脂黏接剂随诊2年并评价疗效,分析感染预防方法。结果实验组在颜色匹配、形态匹配、继发龋、边缘适合性、磨损与断裂方面均较对照组有优势,差异有统计学意义(P<0.05)。结论应用聚合瓷嵌体修复活髓牙大面积牙体缺损的临床疗效优良,患者随访2年后在形态、颜色匹配与功能方面均作用优良。Objective To analyze the living polymerization porcelain inlay restoration dental pulp large clinical efficacy of dental defects and infection prevention. Methods Forty-two cases patients with dental defects after the live pulp tooth of large teeth 48, were randomly divided into experimental group （24 teeth） and the control group （24 teeth）. The experimental group tooth preparation, polymerization porcelain inlay restoration; Control group metal ceramic crowns, resin adhesive application RelyX Unicem 2-year follow-up and evaluated of the efficacy analysis infection prevention methods. Results The color matching, shape matching, secondary caries, marginal fit, wear and fracture strengths in the experimental group were better than the control group, the difference was statistically significant （P〈0.05）. Conclusion Living polymerization porcelain inlay restoration dental pulp excellent clinical efficacy large area of dental defects, pa-tients followed up show functions fine roles in shape, color matching after 2 years.
