AS17B37C - Biomechanics of Lower Molar Protractions Using MSIs

Apr 24, 2017 9:00am ‐ Apr 24, 2017 9:30am


A difficult tooth movement to consistently and reproducibly accomplish without anchorage loss is lower molar protraction. This presentation will outline several of the common methods employed to protract lower molars along with their side effects. Dr. Cope will also present a biomechanically sound miniscrew-based treatment option for protracting lower molars.

Learning Objectives:

  • Appreciate the various mechanical options for molar protraction.
  • Analyze the potential clinical side effects associated with molar protraction.
  • Evaluate the clinical appropriateness of molar protraction in individual cases.
