The use of TADs may be associated to anchorage control and possible facilitation of orthodontic mechanics. However, this is not often the case as the desired effects are sometimes not achieved or often counteracted by significant side effects. Adequate knowledge of biomechanics enables the delivery of forces and moments that can be used in a plethora of clinical problems. The application of force systems that enable to maximize the desired effects on tooth movement while minimizing the side effects is of primary importance.
Describe the one couple system or cantilever system delivered from TADs and its significant versatility.
Outline different biomechanical approaches delivered from TADs for the correction of moderate to severe problems in the vertical dimension.
Illustrate how TADs can maximize the mechanics delivered with Invisalign.
