Results achieved
- Class I relationship achieved
- Functional canine guidance on both sides
- Anterior crossbite corrected
- Normal overjet and overbite achieved
- Midlines coincident
- Proper axial inclination of incisors
- Curve of Spee leveled
- Arches aligned and coordinated
- Alignment of both arches through derotation
- Arch form improved
- Aesthetic smile linewas achieved
- All treatment goals were achieved case
- Harmonic arches were achieved
Comments
- 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
