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. Methods: 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. Results: 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. Conclusion: 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.
