Correction of class III malocclusion using enmasse distalization with tad

Abstract

Skeletal class III malocclusion in adult patients are generally managed by orthognathic surgery. However, the prognosis is poor when the patient refuses surgical line of treatment. In such cases orthodontic camouflage through dentoalveolar compensation may be attempted. Presently, with the advent of stationary anchorage, en mass distalization appears to be a common choice. This article demonstrates an en mass distalization carried out in the upper and lower arches in a class III skeletal case, refusing surgery. After initial levelling and alignment, TADs (temporary anchorage devices) were placed bilaterally mesial to the first molars in upper and lower arches. After a month, distalization was initiated with 300 gms force applied per side using elastomeric chain. At the end of the treatment, the anterior cross bite and crowding was resolved and the patients profile improved. Thus, en masse distalization with TADs appears be a good choice in class III skeletal cases refusing surgery. It is minimally invasive and cost effective.
