Lecture Description

This presentation will deal with biomechanical solutions for maximizing efficiency of orthodontic treatment combined with temporary anchorage devices. Although various treatment techniques have been developed, it remains quite difficult to predict or compare orthodontic tooth movements subsequent to the application of different treatment mechanics. Therefore, the prediction and planning of orthodontic tooth movement have been largely dependent on clinical experiences. With such a background, the demand for simulating long-term tooth movement under the various treatment mechanics has been increasing to improve therapeutic efficiency and reduce the treatment time. It is essential to fully understand the fundamental biomechanical principles, and by using the system for simulation orthodontic tooth movement, the optimal loading condition for achieving speedy and controllable tooth movements can be determined.
We frequently face the problems in the daily orthodontic practice. How should we address complex cases such as severe Class II, open bite, impacted teeth, severely tipped molars? There is no doubt that the best solution is to utilize temporary anchorage devices. Clinical application of temporary anchorage devices combined with the various treatment mechanics will be discussed.

Learning objective
