To study the effects of combined surgical-orthodontic treatment, recordings of functional and border movements were obtained before and after surgery for 16 patients with severe skeletal malocclusions. The tracings showed a clear difference in the functional adaptation to mandibular setback and mandibular advancement surgeries. Patients with a skeletal Class III malocclusion who had undergone mandibular setback surgery generally showed an increase in the range of border and masticatory movements postsurgically. Patients with a skeletal Class II malocclusion corrected by mandibular advancement showed a restricted range of motion immediately postoperatively. Even 12 months after surgery, their recordings did not completely approach presurgical values.
为研究外科正畸联合治疗的效果，对16例严重骨骼性错牙合畸形患者在手术前后进行了功能和边缘运动记录。描记图显示，在下颌后缩和下颌前突手术的功能适应性方面存在明显差异。接受下颌后缩手术的骨骼Ⅲ类错牙合畸形患者术后边缘运动和咀嚼运动范围通常增加。通过下颌前突矫正的骨骼Ⅱ类错牙合畸形患者术后立即出现运动范围受限。即使在术后12个月，他们的记录也未完全接近术前值。
