title: [Statistical analysis of 92 orthodontic cases].
abstract: A comparison has been made within 92 children who were either observed or treated by extractions or by orthodontic  appliances and submitted to statistical analysis. Conventional treatments do not influence the skeletal structures except for the convex faces which are favorably modified by plate. The changes of the dental axis varied according to the dental group. The growth direction of the anterior facial structures seems to be constant amongst all considered children.
