摘要/Abstract

摘要： 目的评价全氧化锆嵌体冠修复牙合龈距严重不足者下颌患牙的疗效。方法选择下颌后牙牙合龈距小于2 mm，无法行全冠修复的21个病例，根管治疗术后，制作21个全氧化锆嵌体冠进行修复。结果经2~3年随访观察修复体的边缘密合性、牙龈指数、崩瓷现象等指标，21个修复体使用正常。患者对牙体外形及功能恢复满意。结论全氧化锆嵌体冠对于治疗下颌牙合龈距严重不足患牙是一种简单、易行、效果良好的修复方法。

Abstract: :Objective To observe effects of zirconia inlay crown in the restoration of mandibular molars with extensively closed occlusogingival distance. Methods 21 residual crowns of molars which were hard to restore using common crowns because of their closed occlusogingival distance less than 2mm were treated after root canal therapy with zirconia inlay crowns. Results After a 23 year period, the inlay crowns were all maintained well, with good marginal sealing, acceptable gingival index and no porcelain collapse. The restoration of the teeth shape and its function recovery were both satisfactory. Conclusion For the restoration of mandibular molars with extensively closed occlusogingival distance, the zirconia inlay crown is an easy and simple technique to apply, with satisfactory clinical restoration effects. 
