Comments
- Upper incisor and canine Alignment
- Lower incisor spacing closure
- Retraction of upper and lower incisors and canine
- Posterior expansion of upper and lower arch.
- IPR upper arch: 0.5mm at upper molars, premolars, canines, incisors
- IPR lower arch: 0.3mm at lower premolars, canine and incisors
- Lingual root torque of upper and lower premolars and canines: individual tooth lingual torque was planned with the ClinCheck Pro feature
- Relative extrusion of upper and lower incisors and canines was provided by retraction of upper and lower incisors and canine.
- Extrusion of upper and lower incisors and canines was programmed to treat and correct the upper and lower reversed curve of Spee
- Passive intrusion ( 1-2 mm ) of upper and lower molars and premolars with aligner wear
- Full-time aligner wear and Class II elastics
