Premature occlusal contacts may force the mandible into a not optimally functional intercuspal position, a so-called forced
bite. When the mandible is forced laterally, it is called a lateral forced
bite, more prevalent in children than in adults. In the PhD thesis (1983) 'Mandibular movement patterns: a methodological and clinical investigation of children with a lateral forced
bite', open-close-clench cycles had been studied in 12 children with a lateral forced
bite and in a control group of 6 children. Their mandibular movements were registered using an opto-electronic registration technique. Only in the children with a lateral forced
bite, the mandible appeared to be displaced laterally into the direction of the forced
bite side both during cycle series into intercuspal position and, although to a lesser extent, when occlusal contact was eliminated using flat
occlusal splints. Apparently, in children with a lateral forced
bite the neuromuscular co-ordination of the temporomandibular joint is disturbed. Subsequent research projects demonstrated similar findings. Consequently, a lateral forced
bite in children should be eliminated as early as possible, in order to enable normal growth and development of the stomatognathic system.
