Occlusion: An Orthodontic Perspective

Abstract

In recent years, orthodontists have examined their concepts of occlusion. In current literature, at professional meetings, and in continuing education courses, one hears an ongoing discussion of condylar position and mandibular border movements in relation to occlusion. There is a wide variation in opinion as to whether dental occlusion and TMJ function are interdependent. The authors have adopted a dynamic concept of dental function to replace the traditional static view of molar relationship and incisor overlap. This article discusses how occlusion has evolved in orthodontics and reviews Andrews' six keys to ideal static occlusion, the goals of ideal dynamic occlusion, and the six signs of developing malocclusions. The authors also review the literature on the relationship between orthodontics, occlusion, and TMD.
