摘要/Abstract

摘要： 目的：探讨改良铸造桩核全瓷冠修复前牙的临床效果。方法：选择前牙唇倾明显的患者32例,患牙45颗,行改良铸造金合金桩核+氧化锆全瓷冠修复,采用美国加州牙科协会制定的标准,分别于修复完成当天、6个月、1年对修复体的边缘密合性、解剖外形、表面光滑度、颜色及牙龈状况进行评价。结果：44颗全瓷冠修复效果良好(97.8%),1颗全瓷冠的牙龈状况达B级(2.2%)。结论：改良金属桩核+氧化锆全瓷冠适用于需要改向的前牙美容修复,可在临床上推广应用。

Abstract: PURPOSE: To evaluate the clinical effect of modified casting post with zirconia crown in restoration of anterior teeth. METHODS: A total of 45 anterior teeth (32 patients) were treated with modified gold-alloy post-cores with zirconia crowns. All roots were greatly tilted to the labial side. Marginal integrity, anatomic form, surface, color and the gingival situation after restorations were assessed at 6 and 12 months with the California Dental Association (CDA) quality assessment system. RESULTS: The clinical outcome of 44 zirconia crowns achieved rank A (97.8%), while the gingival situation in one patient (2.2%) reached rank B. CONCLUSIONS: Modified gold-alloy post-core with zirconia crown contributes to the aesthetic effect of the anterior teeth which need to change the angle.

Key words: Modified casting post, Zirconia crown, Gold-alloy post-core
