前牙氧化锆全瓷单冠修复的短期临床效果评价

Short-term clinical evaluation of single zirconia crowns for restoration of anterior teeth

目的对56例前牙缺损患者行LAVA氧化锆全瓷冠修复的短期临床效果进行评价及分析。方法选取56例前牙缺损、行LAVA氧化锆全瓷单冠修复的患者按照标准程序制作全瓷修复体85颗,对修复后3、6及12个月进行临床随访调查,并由患者根据评价疗效、填写修复满意度调查表,根据改良USPHS标准对全瓷冠修复体的临床疗效进行评价。结果 12个月内的随访中,56例患者85颗修复体其各项指标都达到Bravo标准。修复体颜色匹配率达到Alpha标准的97.6%,修复体外形达到Alpha标准的97.6%。修复体的边缘适合性达到Alpha标准的84.7%,其中有15.3%处在Bravo标准上。修复体的材质达到Alpha标准95.3%。结论 LAVA全瓷单冠修复体的外形美观、层次感强、对前牙缺损病例修复效果较好。

Objective To evaluate short-term clinical performance of single LAVA zirconia crowns for restoration of anterior teeth. Methods 56 cases of anterior teeth defect patients received LAVA zirconia all-ceramic single crown restorations.
