A comparison of soft tissues changes in patients with skeletal class Ⅲ malocclusion after orthodontic and surgical treatments
Objective: Investigate the effect of orthodontic treatment combined with orthognathic surgery operation in treatment of skeletal class III malocclusion deformity on bone and soft tissue in patients. Methods: Collected 68 cases of patients accepted treatment in our hospital from January 2012 to January 2014 were given orthodontic treatment and orthognathic surgery operation. Through the X-ray cephalometric detected changes of skeletal and soft tissue before treatment, 3 months and 1 year after operation. Results: Compared with the prior correction, in addition to the angle of up and under lip other projects changed obviously 3 months after operation (P<0.05). Compared with 3 months after treatment, other projects in addition to lower lip base angle, Z angle, UL angle, soft tissue facial angle and facial angle were no significant change (P>0.05). Conclusion: Orthodontic treatment combined with orthognathic surgery operation in treatment of skeletal class III malocclusion deformity have significant curative effect after 3 months after operation, and there is a slight relapse one year after the operation, but no essential influence on the operation effect.
