前牙唇侧齐龈肩台EMAX铸瓷全冠修复后唇侧牙周状况的评价

目的评价前牙唇侧齐龈肩台EMAX铸瓷全冠修复后唇侧牙周状况。方法对120颗前牙预备唇侧齐龈肩台,行EMAX铸瓷全冠修复。在修复前,修复后6个月,修复后1年和修复后2年分别采集唇侧龈沟液,测定龈沟液（gingivalcrevicular fluid,GCF）髓过氧化物酶（myeloperoxidase,MPO）的含量,同时记录唇侧牙周的牙龈指数（gingival index,GI）和牙周探诊深度（Pocket depths PD）。结果前牙EMAX铸瓷全冠在修复后6个月,修复后1年,修复后2年和修复前相比,牙龈指数GI、牙周探诊深度PD和龈沟液髓过氧化物酶MPO均无显著性差异（P〉0.05）。结论前牙EMAX铸瓷全冠修复体在临床上可获得理想的美学效果和边缘适应性,修复后2年唇侧牙周状况良好。

Evaluation labial periodontal detection of EMAX full ceramic crown with quigingival margin at labial side for anterior teeth

Objective To evaluate labial periodontal detection of EMAX full ceramic crown with equigingival margin at labial side for anterior teeth.Methods 120 anterior teeth restored with EMAX full ceramic crown with equigingival margin at labial side were evaluated of their labial periodontal detection by recording GI,PD,GCF-MPO before,after 6m,1y,and 2y of crown bonding.Results There＇s no significant difference（P0.05）in GI,PD,GCF-MPO before,after 6m,1y,and 2y of crown bonding.Conclution EMAX full ceramic crown with equigingival margin at labial side has good clinical effect in esthetic and marginal fitness and labial periodontal detection after 2y of crown bonding.
