2018 Annual Session Conference

How to Avoid Side Effects in Orthodontics

May 7, 2018 8:40am ‐ May 7, 2018 9:25am


Many orthodontic appliances are used incorrectly, often leading to unexpected adverse side effects, such as anchorage loss, cuspid rotation during retraction, bite deepening by sliding mechanics, occlusal plane caning after leveling and so on. In cases like these, we have to treat not only the malocclusion of the patient but also the adverse side effects that we have made in the course of the treatment as well. Application of correct biomechanical principles is therefore key in obtaining predictable treatment results with minimal adverse side effects, or even in replacing such adverse side effect with beneficial side effects.

Learning Objectives:

  • Recognize the adverse side effects in the reactive unit.
  • Recognize the consistent force system at the active unit.
  • Recognize how to reduce adverse side effects.
