Anterior maxillary intrusion and retraction with corticotomy-facilitated orthodontic treatment and burstone three piece intrusive arch

Ramachandra Prabhakar et al. J Clin Diagn Res. 2013 Dec.

Abstract

An adult patient with proclination and spacing was performed orthodontic treatment combined with corticotomy and the burstone three piece intrusive arch who desired a shortened treatment period. The patient had Angle's Class I malocclusion with flaring of the maxillary and mandibular incisors. Pre adjusted edgewise appliance (MBT prescription) was fixed to the maxillary and mandibular teeth. Then corticotomy was performed on the cortical bone of the buccal sides in the maxillary anterior regions. Intrusion and retraction initiated immediately after the corticotomy. The intrusive arch was adjusted once in every 2 weeks. The total treatment time for intrusion was 5 months. Cephalometric superimpositions showed no anchorage loss, and panoramic radiographs showed neither significant reduction in the crestal bone height nor marked apical root resorption. A corticotomy-facilitated orthodontic treatment shortened treatment period without any anchorage loss or adverse effects.

Keywords: Corticotomy; Intrusion.
