Abstract

This is a case of female adult patient with skeletal Class Ⅱ malocclusion. The problems of this case are as the followings: maxillary protrusion, mandibular retrusion, convex facial profile, gummy smile (>10mm), 16mm overjet, 2mm overbite, upper and lower anterior teeth crowding, and #35, #36, #46 missing. The treatment was performed by extraction of upper first premolar with traditional fixed orthodontic appliances combined with orthognathic surgery. The surgery method composed of LeFort Ⅰ two pieces osteotomy for maxillary intrusion and retraction, mandible autorotation forward and upward, and genioplasty for chin advancement. In addition, #44 was autotransplanted to the edentulous area of #35. The upper jaw relapse was noted after unwiring from interocclusal stent. The upper midline deviated to the right about 4mm, overjet increased to 5mm, overbite increased to 4mm, and right posteriors became crossbite. The mini-screws, then, were used as an anchorage to successfully move and rotate upper arch to the left, retract anterior teeth, and correct right posterior crossbite. In conclusion, orthodontic min-implants not only can correct teeth, but also move jaw dramatically.
