[A clinical study of the changes of condylar position in class division 2 deep-bite patients after orthodontic treatment].

Abstract

OBJECTIVE:

To observe the effects of orthodontic treatment on the changes of condylar position in Class division 2 deep-bite patients.

METHODS:

11 patients with Class division 2 deep-bite malocclusion were orthodontically treated, the changes of condylar position were evaluated by means of 3D-CT and Sam-diagnostic articulator.

RESULTS:

With the increase of inclination of upper incisors and opening bite, there were statistically significant changes of condylar longitudinal distance and condylar height in both sides, and retruded contact position-intercuspal position(RCP-ICP) discrepancy was significantly reduced.

CONCLUSION:

The condylar position in division 2 deep-bite patients could be orthodontically changed, moving anterior-inferiorly and approaching RCP.
