Fig.11: Pre and post-treatment ClinCheck™ assessment
Seventeen upper and lower aligners were used to initially extrude the upper anterior segments (at the rate of 2 weeks per aligner) by approximately 3mm and also to intrude the upper posterior segment by 1mm.(Fig. 11) In order to achieve this, the patient was asked to wear additional inter maxillary elastics (1/8, 3.5 Oz) from the hooks fabricated on the upper canine to the ones on the lower canine and premolar, in a triangular fashion and only at nighttime.
