目的观察前牙氧化锆全瓷粘接桥的修复效果,为氧化锆全瓷粘接桥修复的适应证选择和临床应用提供参考.方法选择23例单颌缺失1～2颗前牙的患者,进行单翼或双翼氧化锆全瓷粘接桥修复.随访时根据美国公共健康协会标准,观察粘接桥的完整性、边缘着色、继发龋和颜色匹配性.结果共制作粘接桥29件,其中单翼粘接桥23件,双翼粘接桥6件.观察14～30个月,平均22个月.1件双翼粘接桥修复失败,2件单翼粘接桥修复失败.26件粘接桥无边缘着色,无继发龋,仅2件单翼粘接桥颜色偏白.粘接桥累积生存率为90%(26/29).结论对单颌缺失1～2颗前牙的患者进行氧化锆全瓷粘接桥修复,可以达到恢复前牙美观和功能的效果.

Objective To observe the restoration effect of anterior all zireonia ceramic resin bonded fixed partial dentures,and to find a new fixed restorative method for restoring one or two missing anterior teeth.Methods Twenty-nine missing anterior teeth from twenty-three patients were restored with all zirconia ceramic resin bonded fixed partial dentures,and restorations were devided in to two groups according to the number of retainers.i.e.the single-retainer group and the two-retainer group.The integrity,secondary caries,margihal shade and color match of the restorations were evaluated with the standard of American Public Health Association(APHA).The average period of observation was 22 months.Results One restoration from the two-retainer group failed,two restorations from the single-retainer group failed.The shade of two restorations were evaluated as discernable whiter compared tO adjacent teeth.There was no secondary caries and marginal shade.The two year Success rate of anterior all zirconia ceramic resin bonded fixed partial dentures was 90%(26/29).Conclusions All zirconia ceramic resin bonded fixed partial dentures used for less than two anterior missing teeth can achieved definite aesthetic effect and physiologic function.It was a new type of fixed restoration for anterior missing teetII.However,to determine long-term result of this restoration more data are needed.
