| 摘 要： | 目的尽可能保存下颌后牙的残根残冠，提高患牙的保存率。方法对下颌后牙残根、残冠累及根分叉病变的２４个患牙，采用分根法作保存修复。结果保存修复的成功率下颌第一恒磨牙为９４％，第二恒磨牙为６７％。结论只要控制根分叉感染，适当减小患牙的牙合力，保存修复不但能恢复患牙本身的形态和功能，尚能使一些不能做固定修复的病例变为可能。

| Abstract: | Objective To conserve mandibular prsterior residual roots and crowns as many as possible and to increase the conservative rate of the teeth. Methods Separating roots was used for the conservative prosthetics of 24 mandibular posterior teeth with furcation involvement. Results The successful rate of conservative prosthetics was 94% in the first mandibular molars, while 67% in the second molars. Conclusion As long as the furcation involvement was controled and the occlusal force was reduced, the conservative prosthetics could not only restore the morphology and function of the teeth, but also made it possible for some cases that could not be fixed prosthetic. |
