Posterior mandibular rotations

Abstract

The morphological particularities of the posteriorly rotated mandible, first described by A. Björk, may correspond to extremely variable clinical situations. We can derive important information by analyzing the forms and proportions of different mandibular entities. This article proposes to illustrate the most frequently encountered situations by describing a number of cases of posterior rotation and by explaining how Delaire’s architectural analysis can be used in clinical practice.
