Chin Wing Osteotomy for Improving Mandible Projection and Contour in Patients with Normal Occlusion: Case Reports.

Aim: To present a chin wing osteotomy in two patients who had undergone a virtual surgical planning workflow for surgical procedures and were followed up for 4 years.

Case Reports: Two retrognathic patients with normal occlusion were evaluated by means of dental and facial photographs, cone beam computed tomographs and digitization of dental arches. Virtual surgical planning was performed by using the Dolphin Imaging software to simulate the chin wing osteotomy.

Sleep-disordered breathing following mandibular setback: a systematic review of the literature.

Introduction: A mandibular setback reduces space in the pharyngeal airway, and it has been suggested that it might induce sleep-disordered breathing.

Objectives: An evidence-based literature review was conducted to identify the effect of mandibular setback on the respiratory function during sleep.

Methods: The authors performed a systematic review of pertinent literature published up to 2014.
