Surgical-orthodontic Treatment of Skeletal Class III Malocclusion and Concomitant Open Bite: A Case Report

Surgical-orthodontic treatment for the correction of skeletal Class III malocclusion and concomitant open bite is challenging due to the probability of postsurgical relapse. The present case (19 year-old male) describes successful surgical-orthodontic treatment for the correction of Class III malocclusion with anterior and posterior open bite. Treatment consisted of the use of an Edgewise fixed appliance (0.022” × 0.028”) and bimaxillary orthognathic surgery. Treatment resulted in bilateral Class I molar and canine relationships, normal overjet and overbite, the correction of anterior and posterior open bite, alignment of the midlines, leveling of the curve of Spee, satisfactory facial harmony, and passive lip seal. The correct diagnosis as well as the proper indication and execution of orthodontic and surgical treatments enabled the achievement of satisfactory functional and facial results and smile esthetics
