Nonsurgical treatment with rapid mandibular canine retraction via periodontal ligament distraction in an adult with a Class III malocclusion.
A woman with a Class III malocclusion was a poor candidate for orthognathic surgery. An orthodontic treatment plan was developed that incorporated a relatively new and rapid process of canine distraction. The mandibular first premolars were extracted, correcting the anterior crossbite, the Class III canine relationship, and the Class III facial appearance. The canines were distracted, through the periodontal ligament, into the extraction sites. Dental distraction is a breakthrough for orthodontics, especially for adults with critical anchorage requirements.
