Objective compare the changes in condyle positions, face type lateral position and facial soft tissue before and after clinical correction of adult ClassⅡ Division Ⅰ malocclusion patients accompanied with the temporomandibular disorder. Method there were 7 adult Class Ⅱ Division Ⅰmalocclusion patients with accompanied with temporomandibular disorder, they accepted orthodontic extraction treatment routinely with MBT straight wire appliance technology, by which the occlusion was opened, the front teeth was received within correction, the occlusion was finely adjusted to canine fossa staggered relationship and the overbite cover was proper. Results The face type facial soft tissue profile was changed from raised face before treatment to straight face type and 1/3 of height under the face was increased and the temporomandibular disorder was made better. Conclusion the molars occlusion relationship of adult Class Ⅱ Division Ⅰ malocclusion patients accompanied with temporomandibular disorder was adjusted by opening the occlusion and adducting the upright front teeth , the condylar process was moved forward , the posterior teeth alveolar bone height was increased and the temporomandibular disorder was substantially improved.
