• I investigated histochemical changes in the masticatory muscles and morphological changes in the cranium induced by elevating the vertical dimension of occlusion in growing rats. One hundred and forty-four 4-week-old male Wistar rats were divided into three groups. In the experimental group, the vertical dimension of occlusion was elevated 1mm and 1.5mm bilaterally at the maxillary molars. The weight of the masticatory muscles and the mean diameter of II B fibers had decreased at 7 weeks of age in the experimental animals, the percentage of II B fiber in those muscles had increased, and the height of the mandibular angle had significantly decreased at 7 and l0 weeks of age. These results suggest that elevating the vertical dimension of occlusion retards growth of the masticatory muscles and cranium, and that these changes might be related to a decrease in the diameter of, and an increase in the percentage of, type II B fibers.
