코멘트
- This is a skeletal Class III asymmetric case with Class III malocclusion, crossbite, crowding, and rotation
- We created space with expansion on the upper arch
- Space for the lower arch was gained with both distalization and expansion
- We found Invisalign very effective for arch expansion
- During sequential distalization we used Class III elastics as anchorage
- Through digital ClinCheck design, we were able to determine more precisely how to create and manage space for the implant
