Evaluation of horizontal condylar angle in malocclusions with mandibular lateral displacement using cone-beam
Objectives:
To evaluate the horizontal condylar angle (HCA) in mandibular lateral displacement (MLD).
Materials And Methods:
HCA in MLD malocclusions were examined using cone-beam computed tomography data in subjects with MLD and control subjects.
Results:
HCA in joints of control patients and contralateral side joints of MLD patients were not significantly different. The mean HCA on the shifted side was larger than on the contralateral side (P < .001) in the different HCA groups. HCA was significantly larger on the shifted side than on the contralateral side in skeletal Class I, Class II, and Class III groups (P < .001).
Conclusions:
(1) There was no statistically significant difference between HCA in control patients and on the contralateral side in MLD patients. (2) HCA was significantly larger on the shifted side than on the contralateral side. (3) HCA on the shifted side and the contralateral side in MLD Class I, Class II, and Class III are significantly different.
