Abstract:Objective To analyze the clinical effect of orthodontic combined with orthognathic therapy in treatment of bony dental maxillofacial deformity.Methods 60 cases with bony dental maxillofacial deformity treated in our hospital from January 2015 to March 2016 were selected as the study objects.All patients were treated with the orthodontic combined with orthognathic therapy.And the clinical effect was analyzed.Results SNA,SNB,ANB,OVERBITE and OVERJET indexes were significantly different in comparison with before treatment(P<0.05).Additionally,treatment satisfaction degree was 95.00%,and the incidence rate of complication was 5.00%.Conclusion Orthodontic combined with orthognathic therapy in treatment of bony dental maxillofacial deformity achieves good clinical effect,and it cam significantly improve the relationship between appearance and occlusion and treatment satisfaction degree is high,and incidence rate of complication is low.It is worthy of promotion and application.
