MINIMALLY INVASIVE TECHNIQUE FOR ANTERIOR MAXILLARY RETRACTION & INTRUSION - A PROSPECTIVE STUDY ON A CASE WITH 1 YEAR FOLLOW-UPSALIVARY

Abstract

The conventional treatment for vertical maxillary excess due to Skeletal class II base, is surgical reduction and rigid fixation which has decreased patient acceptance. However, intrusion of some selected MVE cases can be achieved with minimal intervention using mini plate anchorage, thus expediting and simplifying their management. A 15 year old female patient came with a complaint of forwardly placed teeth in the upper front tooth region of the jaw. Intraoral examination showed class II molar occlusion on both sides with increased overjet and overbite. The cephalometric analysis showed class II skeletal relationship with vertical maxillary excess. The treatment plan included Fixed appliance with extraction of 14,24,35, then miniplates and miniimplant assisted anterior maxillary retraction and intrusion. At the end of the treatment anterior maxillary retraction and intrusion was achieved. Thus the hypothesis was accepted as retraction and intrusion using mini plates is an easy, efficient, safe and cost- effective option in the management of VME. It is less invasive with acceptable clinical and radiographic outcome, while avoiding surgery under GA with its risk and complication. Careful case selection is needed for achieving satisfactory result and smile.
