We have treated 22 patients for correction of open bite, using a one-stage posterior maxillary osteotomy, by two different techniques. Relapse was the most significant postoperative complication after this procedure. To avoid the high incidence and, particularly, the severity of this complication, we used long-term (11 to 12 weeks) maxillomandibular fixation to provide for neuromuscular adaptation to the newly derived rest position in the mandible.
我们采用两种不同技术，通过一期上颌后份截骨术治疗了22例开牙合患者。复发是该手术后最显著的术后并发症。为避免该并发症的高发生率，尤其是其严重程度，我们采用了长期（11至12周）的颌间固定，以使神经肌肉适应下颌新获得的休息位。
