Mandibular Rotation and Class III Malocclusion

Abstract

The purpose of this investigation was to examine Class III cases with reverse overjet and low maxillo-mandibular planes angle, before, during and following treatment. Several methods, including Björk's structural method, are used to assess any rotation occurring and the effects of such rotation on vertical facial dimension and antero-posterior jaw relationship. From these observations comments are made on the possible existence of overclosure in these cases.
