摘要
目的观察e.max铸瓷嵌体用于修复年轻恒磨牙牙体大面积缺损的临床效果。方法采用间接法制作e.max铸瓷嵌体,修复年轻恒磨牙大面积缺损32例,随访观察18个月。采用改良USPHS评价标准对修复体及基牙进行评价。采用χ2检验将第1,3,6,12,18个月的A级成功率与戴牙时初始情况进行比较分析。结果观察期间,1例出现嵌体脱落,其余31例临床效果满意。χ2检验分析修复体固位的A级成功率在6个时间节点间比较,差异无统计学意义(P>0.05)。18个月内各项评估A级成功率在96%以上。结论应用e.max铸瓷嵌体修复年轻恒牙牙体大面积缺损,能有效恢复年轻恒牙牙体外形和邻接关系,有效预防基牙继发龋,临床效果满意。
