Classification and Facial Patterns in Dysgnathias of the Maxilla and Midface

The skeletal position of the jaws is genetically determined. Typical positional relationships of the jaws include classifiable occlusal forms and externally recognizable, almost typifying esthetic features of each face. Classification was essential for the development of systematic treatment concepts in order to enable structured treatments in the first place, which must also be communicated internationally. In addition to the statements in Volume I on malocclusions of the mandible, cleft malformations extend the spectrum of growth disorders in the midface. Syndromal malformations of the facial skeleton also belong to this classification for the sake of completeness, but are not discussed here.
