Skeletal class II malocclusion is often occurred in Oriental and Black. It is difficult to gain the ideal treatment objective either using the orthognathic surgery or orthodontic treatment alone. However, the combined orthodontic and surgical treatment can reach it, so we investigate the methods and characteristics of combined orthodontic and surgical treatment in skeletal class II malocclusion.
We analyzed the recent 22 cases with skeletal class II malocclusion in Hospital of Stomatology, West China University of Medical Sciences with 7 male and 15 female from 20 to 30 years old. In the study, we discussed the time of extraction, the peculiarity of orthodontic treatment and the selection of surgery type.
After the combined orthodontic and surgical treatment, all the patients regained satisfactory face appearance and function. The selection of surgery type is decided by the skeletal characteristics of malocclusion (the malformation degree and the position). The upper first premolars were extracted before the orthodontic treatment for the purpose of better curing of surface of the skeletal wound. And the pre and post-surgical orthodontic treatment were very important and necessary to regain the ideal face appearance and function.
The combined orthodontic and surgical treatment is an efficient way to cure skeletal class II malocclusion. Suitable orthognathic surgery and rational orthodontic treatment are important to treat adult skeletal class II malocclusion.
骨性II类错牙合畸形在东方人和黑人中较为常见。单独采用正颌外科手术或正畸治疗难以达到理想的治疗目标。然而，正畸与外科联合治疗能够实现这一目标，因此我们探讨骨性II类错牙合畸形正畸与外科联合治疗的方法及特点。
我们分析了华西口腔医院近期收治的22例骨性II类错牙合畸形患者，其中男性7例，女性15例，年龄在20至30岁之间。在研究中，我们讨论了拔牙时机、正畸治疗的特点以及手术类型的选择。
正畸与外科联合治疗后，所有患者均获得了满意的面部外观和功能。手术类型的选择取决于错牙合畸形的骨骼特征（畸形程度和部位）。正畸治疗前拔除上颌第一前磨牙，以利于更好地愈合骨骼创面。术前和术后正畸治疗对于恢复理想的面部外观和功能非常重要且必要。
正畸与外科联合治疗是治疗骨性II类错牙合畸形的有效方法。合适的正颌外科手术和合理的正畸治疗对于治疗成人骨性II类错牙合畸形至关重要。
