Do you have many attachments on your teeth? I
can't tell by looking at the pictures. How is your provider moving the teeth to
close the bite? I just got invisalign and will be moving the teeth by using a
TAD (temporary anchorage device) to move the back molars up to allow the front
teeth to move down. I'd love to know how you're achieving that kind of movement
so quickly.
He
or she raises a very good questions and I decided to write a post to answer these
questions. Below
is a little information about the categorization of invisalign innovations and
aligntech's mission to improve clinical outcomes and expand the scope of cases
they can take.
Biomechanics:
-Attachments
-Power
Ridges
Staging:
-Velocity
Optimization
-IPR
Staging Protocol improvements
Biomechanics
(both attachments and power ridges) uses force to move teeth. Power ridges and attachments cannot be used together.
Attachments:
Attachments use forces to extrude and rotate your incisors and canines using standard tooth velocities.
Power Ridges:
Power
ridges help add torque to move the root and the crown of the tooth and push the teeth into
their planned position. Power ridges are engineered to apply lingual root
torque. More specifically, they apply just the right amount (based on each
individual case) of movement to force ratio to establish an incisor torque with
lingual root movement.
This is exactly what my aligners look like. I know it's hard to tell from my pictures but the four upper front teeth have power ridges.
