[Impact of early extraction of the 1st molars on vertical dimension].
Early extractions of first permanent molars, done on twenty cases without any orthodontic treatment, have not shown, following the Student's analysis, any statistical difference relative to a pilot group as far as the angles. SN- ANS- PNS, SN-OP, SN-GoGn, FMA, Y-axis are concerned. On the other hand, it has been revealed a closure of the angle ANS- Xi- MP associated with an opening of the mandibular arch.
