Mandibular First Molar Distalization

Overview

A clinical study to test the capability of the mini-screws inserted in the Mandibular buccal shelf area as an anchorage unit to distalize mandibular first molar for correction of mild to moderate Class III cases. The second aim was to detect if there is a difference in the amount of distalization in the presence of unerupted mandibular third molars, using the same technique.

Class III malocclusion in adults is one of the most complex malocclusions in clinical orthodontics. For adults, the ideal treatment option for Class III malocclusion is accomplished either by camouflage treatment in mild to moderate cases or orthognathic surgery in severe cases. Camouflage treatment for Class III malocclusion comprises three main techniques; Class III elastics, mandibular first molar distalization, or extraction of mandibular first premolars. Mandibular first molar distalization via the use of skeletal anchorage has the problem of increased failure rate of the inter-radicular temporary anchorage devices (TADs). Accordingly, a randomized clinical trial using extra radicular TADs in the Mandibular buccal shelf area was designed in the current research aiming to test the efficacy of such a technique in inducing mandibular molar distalization with decreased failure rate, and whether the presence of unerupted mandibular third molars will affect the distalization movement or not.
