全氧化锆嵌体冠在牙合龈距严重不足下颌患牙修复中的应用

Abstract

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. 

Key words: zirconia, inlay crown, closed occlusogingival distance
