超瓷嵌体与复合树脂充填修复治疗垂直型食物嵌塞的临床疗效观察
Modern Medical Journal（2017）
Abstract
目的:比较超瓷嵌体与复合树脂充填治疗后牙垂直型食物嵌塞的临床疗效.方法:将符合标准的74颗食物嵌塞患牙随机分为两组,36颗患牙行超瓷树脂嵌体修复,38颗患牙采用复合树脂充填修复,6个月及12个月后复查其临床效果,根据评价标准对修复体进行评价.结果:6个月后两组临床疗效差异无统计学意义(x2=1.946,P＞0.05);12个月后嵌体组修复成功率高于充填组(x2=6.447,P＜0.05).结论:超瓷嵌体较复合树脂充填修复有较好的边缘适合性,准确地恢复牙体外形和邻接关系,有效地降低食物嵌塞和牙龈炎的发生.
