上颌前部截骨后稳定性的研究

Anterior segmental maxillary osteotomies (ASMO)

为了总结上颌前部节段截骨术后疗效，作者选择１５例应用Ｗａｓｓｍｕｎｄ及折降法（ｄｏｗｎ－ｆｒａｃｔｕｒｅ）行上颌前部节段截骨的病例，术后随访１２个月，检查上前牙切点的移动及术后并发症。总结中发现，术后患者上前牙切点均有不同的移动，移动距离为１．６６±０．７７ｍｍ，临床检查仅发现有牙周袋的形成及牙槽骨的轻度吸收，未发现有严重的并发症。

Anterior segmental maxillary osteotomies(ASMO)were performed with both the Wassmund and downfracture methods in 15 patients and folloned up regularly for 12 months The postoperative maxillary incisor edge point'Is' movements and complications were examined .The results indicated that the point'Is'movement was 1.66±0.77mm postoperatively.No major complications occurred,The stability of anterior segmental maxillary osteotomies was found to be acceptable.
