[Results from a study of the normal values in the vertical, sagittal and transversal plane of early mixed dentitions].
168 (21.7%) of 776 pupils from primary classes in Jena had normal tooth position and occlusion. 94 of them were selected for a longitudinal study. Up to now, they have been examined at the ages of 7 and 8 years. The evaluation of the results obtained showed differences with regard to age and sex. The data reported and the deviations observed may be considered reference values. They concrete the assessment of the growth and development in the orofacial system, facilitate the recognition of dysgnathias which must be treated and optimize the planning and performance of orthodontic treatment.
