| 摘 要： | 目的 比较无饰瓷氧化锆嵌体与铸造金合金嵌体治疗活髓磨牙Ⅱ类洞的临床疗效.方法 选取因龋损或折裂导致的活髓磨牙Ⅱ类洞缺损患牙共60颗,随机分成A组和B组,每组各30颗,分别行计算机辅助设计和制作的无饰瓷氧化锆嵌体修复和金合金嵌体修复,修复后12个月复诊,参照美国公众健康服务修正标准评价治疗效果.结果 修复后12个月,A组有29颗患牙复诊,总成功率为93.53%,B组有28颗患牙复诊,总成功率83.93%,差异有统计学意义(χ2=5.107,P<0.05).美观性评价A组有19颗患牙达到A级,B组没有患牙达到A级,A组的术后美观性评价明显优于B组.结论 对于修复活髓磨牙Ⅱ类洞牙体缺损,使用无饰瓷氧化锆嵌体的美观性和总成功率优于金合金嵌体.

| Abstract: | Objective To compare the clinical effect of the zirconia inlay and gold alloy inlay in the restoration of the second class defect of molar with vital pulp. Methods 60 teeth were randomly divided into zirconia inlay group and gold alloy inlay group, with 30 teeth in each group. Evaluate the restoration effect in 2 group at 1-year follow-up. Results At 1-year follow-up, according to US Public Health Service Criteria, the success rate in anatomy zirconia group was 93. 53%, which was statistically higher than that of the gold alloy group ( P<0. 05) . In the comparison of aesthetics, the anatomy zirconia group was superior to that of the gold alloy group. Conclusion The aesthetic and overall success rate of the anatomy zirconia inlay is superior to that of the gold alloy inlay in the restoration of the second class defect of molar with vital pulp. |
