Abstract

Objective: The aim of this study is to evaluate the condyle-fossa relationship, using CBCT scanning before and after the correction of retroclined upper incisors in class II division 2 subjects, for the detection of possible mandibular functional displacement. Materials and Methods: The sample consisted of 11 Class II, division 2 subjects. Two CBCT scans were obtained for each subject; one before and one after leveling of the maxillary arch. Comparison of the joint space measurements was done for detection of condylar displacement. Results: Statistical Analysis of the sample showed statistically significant decrease in the anterior joint spaces, statistically significant increase in the superior joint space, the posterior joint spaces, and significant changes of the condylar position ratios and percentage. Conclusion: The correction of the maxillary Incisors retroclination of a Class II, Division 2 subjects lead to statistically significant change of the condylar position moving anteriorly and inferiorly. The clinical significance of these values is yet to be investigated.
