The spectrum of malocclusions in patients with horizontal growth pattern

Abstract

The spectrum of malocclusions in orthodontic patients with a horizontal growth pattern was under study. It was found, that in most cases horizontal type of facial growth was combined with malocclusion class II, which was caused by mandibular mycrognathia. Patients with horizontal growth pattern had mandibular protraction much more often, than patients of the control group. It was found that horizontal grows pattern was frequently accompanied by decreased value of an intermandibularangle, anterior position of mandible and maxilla, prominent chin, increased size of a mandibular ramus and decreased mandibular angle value.
