Nonsurgical expansion with modified separator and distalization of mandibular teeth with the aid of mini-implants and sliding jigs in an adult with Class III malocclusion

In this article the author proposes to describe the orthodontic treatment of Class III malocclusion in an adult patient with maxillary expansion and distalization of the mandibular teeth with a mini-implant–supported sliding jig. The results achieved with this therapy were correction of the transverse and anteroposterior maxillary discrepancies, without the need for surgical intervention. The mandibular teeth were distalized, thereby preventing projection. Additional results attained were correction of dental and skeletal relations, with esthetic and functional gain. Thus it was concluded that nonsurgical separation and distalization of the mandibular teeth using a mini-implant–supported sliding jig were shown to be an effective alternative resource in the treatment of Class III malocclusion with limitations.
