Malocclusion patterns in fourteen children with Duchenne's muscular dystrophy.

The purpose of this investigation was to determine whether this myogenic disorder produces a specific pattern of malocclusion. Occlusal relationships, dental arch dimensions, and oral muscular function and morphology were recorded for fourteen boys, aged 8 to 15 years. In all children, a consistently increased arch width indicated oral function patterns that were specific for patients with this type of muscular dystrophy.
