摘要
目的研究正畸-正颌手术联合矫治骨性开[牙合]15年后的骨性以及牙性变化。方法本研究样本为10例成年骨性开胎患者，所有患者均采用正畸-正颌手术联合矫治。上颌采用了LeFortI型截骨术，下颌采用了双侧升支矢状劈开截骨术（BSSO）。选择患者在正畸治疗前（T1）、治疗后（T2）以及正颌手术后平均15年（T3）的头颅侧位片进行头影测量。统计学分析采用t检验。结果双颌手术矫治骨性开雅15年后，虽然骨骼出现了一定程度的复发，但是前牙覆雅基本稳定。结论双颌手术和正畸联合治疗是矫治骨性开骀行之有效的方法。
Objective To study the long-term skeletal and dento-alveolar stability after 15 years of surgical orthodontic correction of skeletal anterior open bite. Methods 10 （8 female and 2 male） patients with anterior open bite who underwent orthodontic treatment in combination with bimaxillary surgery at Hannover Medical University were reviewed. All patients underwent Le Fort I osteotomies combined with bilateral sagittal split osteotomy. The cephalometric records of these patients were examined at the start of orthodontic treatment （T1）, the end of orthodontic treatment （T2） and at average of 15 years of follow-up after surgery （T3）. 8 skeletal and 5 dental cephalometric measurements were selected. Results Although some skeletal relapse was observed in patients with skeletal open bite after 15 years of surgery, overbite remained stable, which is mainly due to the eruption of upper and lower incisors during the follow-up period. Conclusions Treatment of skeletal open bite via Ire Fort I and Bilateral Sagittal Split Osteotomies should be an effective option in treatment of skeletal open bite.
