An unusual extraction pattern for retreatment in a patient with dental protrusion and a deficient soft-tissue chin.
Abstract
A patient with dental protrusion and deficient soft-tissue chin, previously treated with maxillary first premolar extraction, sought retreatment to improve his facial profile. Orthognathic surgery was proposed as the ideal treatment option, but the patient declined. Therefore, other orthodontic options were considered. The combined intrusion and retraction force systems supported with skeletal anchorage on both arches and a midpalatal miniscrew successfully reduced the protrusion and rotated the mandible counterclockwise to improve the facial profile and chin projection. Sagittal correction enhanced by active vertical control with skeletal anchorage and de-wedging with posterior extraction was illustrated. In addition, advancement genioplasty was performed after orthodontic treatment to improve the chin projection further. The mechanics and results of this retreatment case were discussed.
