title: An investigation of a group of 35 consecutive patients with a first arch syndrome.
abstract: Thirty-five consecutive patients with a first arch syndrome were divided into right and left sided and bilateral groups and were investigated clinically, radiographically and electromyographically. The patterns of muscle activity in the inter occlusal position were significantly different in each of the groups. The morphology of the jaw was related to the muscle activity. The implications of the findings are discussed.
