Class II and class III treatment with Dual Activation mechanics and
strategic auxiliaries
Low friction has brought enormous advantages to every Straight-wire
technique. Passive self-ligation has it’s focus points in reducing friction and
thereby increasing efficiency in the speed of leveling and alignment and
sliding mechanics. Nevertheless, friction is not an enemy to the
orthodontist and it is essential for three-dimensional control of tooth
movement. Dual Activation mechanics are the key to efficient alignment,
torque control and a beautiful and effective finishing. The lecture will focus
on the most efficient and effective approach to class II and class III
malocclusions using a Dual Activation system and auxiliaries such as the
Powescope, the Power bar, intra-oral distalizers and orthopedic
appliances. Both compliance and no-compliance mechanics will be
discussed and as well the role of TADs in modern orthodontics.

Learning objectives:

-The characteristics of the Dual Activation System
-The hardware of the treatment phases
-The strategies to solve class II and class III malocclusions
-The use of the efficient auxiliaries to be integrated into
Straight-wire protocols
