Early Expansion and Face Mask Therapy

Early orthopedic intervention remains one of the most powerful opportunities in interceptive orthodontics, especially for young patients with developing underbites. In this presentation of the Advanced Implemntation Course, Dr. Yoon shared a practical, experience-driven walkthrough of modern face mask therapy, expansion protocols, and the small technical refinements that dramatically improve comfort, compliance, and treatment success.

With an emphasis on real-world problem solving, the session highlighted how thoughtful hook design, elastic selection, vertical control, and simple chairside modifications can turn a challenging appliance into a predictable and well-tolerated treatment tool. Dr. Yoon also demonstrated creative adaptations for patients with sleep apnea, solutions for lip and chin irritation, and bite-jumping strategies that support forward maxillary growth.

This presentation offers clinicians a clear, efficient framework for guiding families through early expansion and protraction therapy with confidence.

Five Key Takeaways

• Lingual arms and palatal-centered hooks significantly improve mechanics and comfort.
  

• The choice of elastic size and force matters more than most clinicians realize.
  

• Small modifications dramatically improve compliance.
  

• Vertical control can be adjusted through elastic angulation.
  

• Bite-jumping must be addressed before protraction in deep bite cases.
