Abstract

The 6th Japan Academy of Aligner Orthodontics Annual Congress 2019
Biomechanical Aspect of Extraction Cases in Invisalign System
Invisalign aligners are used to treat extraction cases frequently nowadays. However, it seems to
be difficult to handle the situation for new users. First of all, we must know if only a single force
applied to the crown of the tooth, tipping movement occurs and the result of closing space will
not meet our standard of treatment. Proper incisors inclination control is also needed in all
extraction cases. If we want to move the teeth bodily during space closure, both moment and
force are needed. Anchorage control is also an important issue. In this presentation ,G6
smartforce (differential moment anchorage) will be fully explained.
