Which statement correctly describes a true form treatment for Angle Class III malocclusion?

• A. Orthodontic, with functional appliance
• B. Orthodontic, with mecanical appliance
• C. Orthodontic, with extra-oral appliance
• D. Complex, orthodontic-surgical

Answer: (D)

In a true skeletal Class III malocclusion, the main issue is a mismatch in the jaw bases—mandibular prognathism and/or maxillary deficiency—so the bite is driven by bone relationships, not just tooth alignment. Orthodontic appliances or extraoral devices can tilt teeth or influence growth to some extent, but they can’t reliably reposition the jaws themselves in a way that yields a stable, functional bite for the long term. Therefore, the definitive, stable correction typically requires surgery to reposition the jaws, combined with orthodontics to decompensate the teeth before surgery and to finalize the occlusion afterward. This is why the best treatment option is a complex orthodontic-surgical approach.
