Class III maloclusion orthodontic-surgical treatment: clinical case report

Abstract

To report a clinical case of a patient with Class III malocclusion who had been orthodontically compensated and who later opted for surgical treatment. Orthodontic decompensation treatment was performed to improve the inclinations of the upper and lower incisors. The case was planned virtually through software to simulate three-dimensional maxillary advancement and mandibular retraction. After generating and printing the surgical guide, surgical treatment was performed under general anesthesia. After the surgical procedure, the patient presented a satisfactory recovery, using an appliance for orthodontic completion. After 5 months postoperatively, the orthodontic appliance was removed to enter the containment phase. In the control of 1 year and 3 months, a maintenance of occlusal stability was observed without the presence of recurrence. Radiographic control showed complete bone consolidation and remodeling. The patient presented with a characteristic Class I patient profile. The combination of orthodontic and surgical treatments was effective in correcting the maxillomandibular skeletal discrepancy of the patient who had Class III malocclusion.
