Comments

1.Upper and lower wisdom molars were extracted pre-invisalgn treatment.
2.The lower wisdom molar extraction is a requierement in this treatment due to lower arch sequential distalization planned at clincheck treatment plan.
3.The hyperexpansion of upper right first premolar was corrected planning lingual movement with simoultaneous torque control.
4.We planned sequential lower arch distalization to correct the class III molar and canine into class I molar and canine.
5.Lower arch sequential distalization provided space in order to retract lower anterior teeth and therefore correct crossbite of upper lateral teeth.
6.The anterior overjet created allowed us to retract upper incisors and therefore correct dental biprotusion.
7.Patient collaboration during total treatment time was excellent wearing full time ( 22 hours/day ) aligners and class III elastics.
