ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between condyle movement and temporomandibular disorders (TMD) in patients with Class II division 1 malocclusion.</p><p><b>METHODS</b>Twenty patients (from 11 to 12 years old) with Class II division 1 malocclusion before treatment were collected. Computer aided diagnosis axiograph (CADIAX) and magnetic resonance images (MRI) were used to analyze the condyle movement between disc displacement and normal groups.</p><p><b>RESULTS</b>The sensitive values were found in open/close process in patients with disc displacement Y [Left (0.32 +/- 0.10) mm, Right (-0.91 +/- 0.49) mm ], Z [Left (4.20 +/- 0.70) mm, Right (3.44 +/- 0.21) mm], sagittal condylar inclination (SCI) [Left (32.48 +/- 7.70) degrees , Right (33.47 +/- 12.60) degrees ] and horizontal condylar inclination (TCI) [Left (-2.60 +/- 2.02) degrees , R (-9.23 +/- 5.58) degrees ], and those items showed significant difference between two groups.</p><p><b>CONCLUSIONS</b>The side shift of condyle movement in maximum open/close process might be the inducement of disc displacement. It was revealed that the changes in condyle movement could give useful information in early stage of functional treatment.</p>
