The long-term effects of segmental alveolar osteotomy are reviewed. Thirteen patients attended a follow-up appointment between 5 and 9 years after operation and investigations related to the teeth, their supporting structures and the osteotomy bone cuts. The teeth involved in the osteotomies which gave a vital response after 1 year with ethyl chloride all maintained this response in the long term and about half the number of the teeth not responding at 3 years had recovered this response after 5 years or more. The incidence of periodontal pocketing, non-vital teeth and tooth mobility was low. There was radiographic evidence of the osteotomy bone cuts in more than half of the cases in the long term, although clinically, union had occurred in all cases. The occlusion was stable in all except one class II div. 2 case, which had been treated by lower segmental osteotomy only, where relapse had occurred.
本文回顾了节段性牙槽骨切开术的长期效果。13名患者在术后5至9年接受了随访，随访内容涉及牙齿、其支持结构以及骨切开术的骨切口。在术后1年用氯乙烷测试时有活力反应的参与骨切开术的牙齿，在长期随访中均保持了这种反应，且约一半在3年时无反应的牙齿在5年或更长时间后恢复了这种反应。牙周袋形成、牙齿失活和牙齿松动的发生率较低。从影像学上看，超过半数的病例在长期随访中仍有骨切开术骨切口的证据，尽管在临床上所有病例均已愈合。除1例仅接受下颌节段性骨切开术治疗的II类2分类病例出现复发外，所有患者的咬合关系均保持稳定。
