Classification Case report
Case: An adult male asked for treatment with the chief complaints of facial asymmetry, concave profile, short lower third facial height, skewed front teeth, and unaesthetic smile. By clinical examination and cephalometric analysis, he was diagnosed as skeletal Class III with maxillary retrognathism, mandibular prognathism, and hypodivergent facial pattern with severe crowded upper dentition. We provided a nonextraction surgery-first approach. Bilateral upper and lower TADs were placed for postsurgical distalization of dentition to relief anterior crowding.
Discussion and Summary: The surgery-first approach has improved rapidly since its introduction. The indication for the surgery-first approach has widened with technical advancement such as SAS, CASS and 3D printing cutting guide. However, the limitations and skeletal implications of this approach should be considered. Team approach between surgeons and orthodontists is a vital component for successful treatment.
