Retraction of the upper maxillary incisors with corticotomy-facilitated orthodontics and mini-implants

Abstract

This report describes a case of 21-year-old female with severe maxillary protrusion, and class ІІ/1 dental relationship. The treatment plan was extraction of upper first premolars and retraction of the anterior teeth. Mini-implants were used to provide maximum anchorage to maintain the extraction space. To shorten the retraction time selective alveolar corticotomy was combined with orthodontic therapy. The treatment time was reduced without any adverse effects on the periodontium and the vitality of the teeth.
