Virtual surgical planning: Balancing esthetics, practicality, and anticipated stability in a complex Class III...

The treatment of skeletal Class III malocclusion with anterior open bite is a complex and challenging aspect of orthodontics. Facial esthetic factors, practicality and the anticipated stability of a provisional surgical plan must all be factored into the final decision of the actual orthodontic-orthognathic treatment. This case report presents the multidisciplinary treatment of a 39-year-old female patient with skeletal Class III, severe open bite with first dental contact being on the second molars, lateral crossbite, and crowding in both arches. The nonextraction treatment started with aligning and leveling of the teeth in both arches followed by an initial surgical plan based on the clinical evaluation of the smile esthetics. Precise surgical planning information was imported into the Virtual Surgica (VSP Orthognathics) workflow to visualize the direction and amount of movement necessary. The final plan was adjusted because of anticipated practical limitations of the surgery as well as to insure the stability. LeFort I, bilateral sagittal split osteotomies, and setback genioplasty were thus performed. After the surgery, the treatment concluded with the fine adjustment of the occlusion. In the end, good esthetic and functional outcomes with long-term stability were achieved as a result of this delicate multidisciplinary approach.
