The Use of Clear Aligners in the Management of the Orthodontic Treatment before and after Class III Surgical Approach

Abstract

The approach to skeletal dysmorphisms in the maxillofacial area usually requires an orthodontic treatment by means of fixed appliances, both before and after the surgi- cal phase. Since its introduction, Invisalign system has become a popular treatment choice for the clinicians because of the aesthetics and comfort of the removable clear aligners compared with the traditional appliances. Therefore, the aim of the present report was to illustrate the management of a malocclusion by means of clear aligners associated with the traditional surgical technique. The present paper shows a case of a 18-year-old female patient characterized by a Class III malocclusion with lateral deviation of the mandible. Clear aligners were used during the pre- and postsurgi- cal phases rather than fixed appliances. The posttreatment cephalometric analysis emphasized the stability of the dental and skeletal symmetry corrections, occlusion and functional balance, over a 4-year follow-up. The results achieved at the end of the treatment showed how clear aligners can be effective in the management of the orthodontic phases in orthognathic surgery. The follow-up after 4 years emphasizes the stability of the treatment over time.
