Commentaires
- The treatment was designed to control the upper and lower arches in three dimensions. Both arches were expanded and coordinated.
- Distalization and intrusion of upper molars and retraction of upper anterior teeth corrected Class II molar relationship and open bite simultaneously.
- All treatment goals were achieved as designed in the ClinCheck plan.
- The actual numbers of upper aligners were 22+10+36 with 2 additional aligner orders. The reason was that the patient’s mandible position was unstable and always went forward, so the ClinCheck plan was modified to reduce the pre-mature contact of the anterior teeth.
- The actual numbers of lower aligners were 15+10+6. More IPR was done to decrease the proclination of the lower incisors.
