Orthodontics · single question

A patient has a significant skeletal Class III malocclusion with sleep apnea who is unhappy with facial appearance. What is the recommended treatment?

  1. Orthodontic treatment alone
  2. Extraction-based camouflage orthodontics
  3. CPAP machine only for sleep apnea
  4. Orthodontic treatment combined with orthognathic surgery
Show answer and explanation

Correct answer: D. Orthodontic treatment combined with orthognathic surgery

  • A. Incorrect. Orthodontic camouflage cannot correct a significant skeletal Class III discrepancy — only mild cases.
  • B. Incorrect. Extraction-based camouflage can mask mild Class III, but is inadequate for significant skeletal discrepancy with facial concerns.
  • C. Incorrect. CPAP manages sleep apnea symptoms but does not correct the skeletal discrepancy or facial appearance.
  • D. Correct. Significant skeletal Class III with facial appearance concerns requires COMBINED ORTHODONTICS + ORTHOGNATHIC SURGERY. Orthodontics aligns the teeth on their respective bases; surgery (Le Fort I and/or BSSO) corrects the underlying skeletal discrepancy. This also frequently improves airway and sleep apnea.
