Anchorage miniplates on anterior open-bite treatment

Abstract

INTRODUCTION: The case report presented describes an orthodontic treatment supported by miniplates of an adult female patient who presented severe anterior openbite, clockwise rotation of the mandible, biprotrusion and the absence of labial sealing. After extraction of first molars and maxillary and mandibulary dental retraction, associated with vertical control provided by the miniplates, the anterior openbite was corrected with a little anti-clockwise rotation, resulting in a significant improve on facial appearance. AIM: This case report confirms the efficiency of titanium miniplates as temporary anchorage, especially in situations where great corrections are needed, involving a vertical problem.
