单侧上颌骨缺损,由于骨质缺损广泛,组织支持区减少,余留牙位于一侧,从而在固位设计上增加了困难。多年来,我科应用塑料的中空式阻塞器修复,由于硬性阻塞器不可能是全部进入所有倒凹区,所以很难获得良好的固位。近年來,我科对5例单侧上颌骨缺损病人,改用磁石与磁性合金组合使用,制作上颌分段修复体。通过临床观察、效果满意,修复体固位和稳定性增强。 Unilateral maxillary defects, due to a wide range of bone defects, reduced tissue support area, the remaining teeth on one side, which in the retention design increased difficulty. Over the years, our department applied plastic hollow blocker repair, because hard blocker can not be all into all the concave area, so it is difficult to obtain a good retention. In recent years, our department on 5 patients with unilateral maxillary defect patients, the use of magnets and magnetic alloys in combination, making maxillary segmental prosthesis. Through clinical observation, the effect is satisfactory, and the retention and stability of the prosthesis are enhanced.
