| description | 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. Next, three-dimensional models were imported into computer-aided design system (Rhino 6) for designing two hybrid (dental-bone supported) cutting and repositioning guides. Chin wing osteotomies were carried out by using the cutting guides and the osteotomized segments were placed by using L-shaped plates and screws assisted by the repositioning guides. Bone grafts were interposed in the mandibular angle region bilaterally. In both cases, the patients reported aesthetically and functionally favorable outcomes.
Conclusion
Chin wing osteotomy is an appropriate treatment for retrognathic mandible in patients with normal occlusion and no additional discrepancies as the technique provided chin advancement and improvement in facial contour. The post-operative outcomes showed reliable workflow of virtual planning and surgical procedures, which could be adopted as an alternative in similar cases. |
