The biomechanics of correction of unilateral dental crossbite

Renato Parsekian Martins

INTRODUCTION: The treatment of unilateral crossbite offers some challenges to the orthodontist. OBJECTIVE: The present article proposes to diagram, explain and exemplify, by means of a clinical case, the use of the differential pressure technique applied to the periodontal ligament for the treatment of unilateral dental crossbite. CONCLUSION: It is concluded that the differential tension strategy applied to the periodontal ligament can successfully treat unilateral dental crossbite without causing harmful effects on the opposite side.
