Abstract　： The alteration of the vertical height of dentition and the inclination of the occlusal plane during growth are only poorly established. In order to know the relationship between the vertical dimension and the growth of the facial complex, we examined vertical dental and skeletal height and mandibular growth using dental cast and cephalograms of 25 children which were available from 6 through 14 years of age. Considerable side of dentition (58%) obtained Class I molar relation before exchanging buccal segment and almost all of the Class II at the beginning of IIIB showed Class II occlusion at the final occlusion stage, indicating rarely available Lee way apace. The Class II skeletal group showed a significantly higher eruption of lower first molar, while Class III skeletal group showed a significantly higher eruption of upper first molar. There were significant differences of posterior occlusal plane in different skeletal frames, steeper posterior occlusal plane in Class II skeletal and flat posterior occlusal plane in Class III. Significant correlation between the vertical dimension and the forward mandibular growth was observed. The results of this study suggested that the increase in vertical dimension and inclination of the posterior occlusal plane contribute to mandibular growth and that improper vertical dimension and inclination of posterior occlusal plane are related with the development of skeletal malocclusions.
