目的分析不同桩数的纤维桩修复无牙冠组织壁的磨牙残根的临床疗效.方法选择47例51颗根充完善且无牙冠组织壁的磨牙残根, 进行不同桩数的纤维桩-树脂核与全冠修复, 其中1根纤维桩核修复(1根组)17例18颗, 2根纤维桩核修复(2根组)14例16颗, 3根纤维桩核修复(3根组)16例17颗.随访观察2年, 比较修复效果.结果三组修复成功率比较差异具有统计学意义(P<0.05), 3根组的疗效高于1根组(P<0.05).6颗修复失败的原因均为纤维桩脱落, 其中1根组脱落率大于3根组(P<0.05).结论当纤维桩修复无牙冠组织壁的磨牙残根时, 1根纤维桩的临床修复效果较差, 尽量避免使用.

Objective To analyze clinical effect by different fiber posts number in repair of molar residual root without dental crown wall.Method A total of 47 cases, as 51 teeth, of molar residual root without dental crown wall were chosen. They received repair by different number of fiber post-resin core and complete coronal. Among them, there were 17 cases, as 18 teeth, received 1 fiber post for repair (1 posts group), 14 cases, as 16 teeth, received 2 fiber posts (2 posts group), and 16 cases, as 17 teeth, received 3 fiber posts (3 posts group). Follow-up lasted for 2 years, and the repair effects were compared.Results The differences of success rates across the three groups had statistical significance (P<0.05). Curative effect of 3 posts group was higher than that of 1 post group (P<0.05). There were 6 failed teeth due to fallen fiber post. 1 post group had higher failure rate than 3 posts group (P<0.05).Conclusion Clinical repair effect by 1 fiber post for molar residual root without dental crown wall is poor, and its application should be avoided.
