ABSTRACT
Objective To investigate the imaging and condylar movements during mandibular opening/closing movement in AngleⅡ2 malocclusion accompanying one side of temporomandibular joint(TMJ)click before and after orthodontic treatment.Methods There were 20 AngleⅡ2 malocclusion patients with one side of TMJ click in treatment group,and 23 with the individual normal occlusion in control group.This study was performed taking the films of Sch?ller position before and after treatment,using CADIAX to record the condylar tracings during opening/closing movement and analyze the qualitative and quantitive changes.Results In AngleⅡ2 malocclusion patients,the condylar position of 58.33% patients recovered from retroposition to mesoposition.The condyle movement presented conspicuous verticality,the smoothing and symmetry were not well,and obvious improvements were observed after the treatment.All the index changed remarkably except the TCI and TCI of 5 mm.Conclusion It is suggested that orthodontic treatment can make the disc-condyle relationship return to normalization,and the condylar movement become much more coherent.
