Computer-aided surgical workflow in a surgery - First orthognathic approach to correct anterior open bite in a young adult with temporomandibular disorders.

An 18-year-old female patient with temporomandibular disorders (TMD) history sought medical care in orthodontic-orthognathic interdisciplinary department with chief complaint of anterior open bite. After splint therapy to seat the condylar into the musculo-skeletally stable position, a surgery-first approach was formulated assisted by 3D virtual planning and transferred to the surgery by computer-aided manufacturing splint. No TMD symptom reoccurrence was reported or noted. Stable occlusion and satisfactory facial aesthetics were achieved. In the 18-month follow-up, no clinically significant open bite relapse occurred. This case report describes the remarkable role that computer-assisted surgical simulation could play throughout the surgical-orthodontic procedure to correct the skeletal open bite deformity.
