中文摘要
目的 评价铸瓷高嵌体修复严重缺损的年轻恒磨牙的临床效果。方法 选取牙体严重缺损的第一恒磨牙60颗,随机分为2组,分别进行树脂直接充填（树脂组）和铸瓷高嵌体修复（高嵌体组）。在修复后3、6、12、24个月检查两组患牙的修复体状态及咬合情况。按照改良USPHS/Ryge标准对修复体进行评价,使用T-Scan Ⅲ咬合分析系统进行咬合分析,记录牙龈状况和邻接关系恢复情况。结果 治疗后12个月,两组边缘适合性评分的差异有统计学意义,高嵌体组的A级多于树脂组（PPPP>0.05）。两组的牙龈状况和食物嵌塞情况均无明显差异（P>0.05）。结论 在本研究条件下,高嵌体组在修复体边缘适合性和表面光滑度方面,成功率较树脂组高,咬合力恢复也较树脂组更佳。在修复牙体严重缺损的年轻恒牙时,铸瓷高嵌体修复可作为推荐方案之一,有较好的修复效果。
英文摘要
ObjectiveTo analyze the effect of ceramic onlay to repair serious defects in young permanent molars.MethodsSixty patients with defects in young permanent molars were selected. The patients were randomly divided into two groups. One group was restored with ceramic onlay, and the other used resin composite to direct filling. Follow-up visit was conducted at 3, 6, 12, and 24 months after treatment. Modified USPHS/Ryge criteria were used to evaluate the effect of restoration. The occlusal courses were recorded by the T-Scan Ⅲ system in intercuspal position. Gingival and food impaction were recorded. The effect of the two restorative methods, the recovery of occlusal function, and the gingival and approximal conditions were analyzed.ResultsAt 12 months after restoration, the marginal fitness in the onlay group was significantly better than that in the resin group (PPPP>0.05). The gingival and approximal conditions also demonstrated no statistical differences (P>0.05).ConclusionThe ceramic onlay repair method is better than resin composite filling in marginal fitness, surface smoothness, and recovery of the occlusal function when restoring young permanent molars with serious defects.
