Comments
- Sequential Distalization was used to create space for relief of crowding and improve protrusive teeth.
- Expansion and IPR protocols helped to build up symmetric and coordinated archform.
- Lower anterior intrusion to level COS.
- Class II elastic was used to improve overjet correction and extrude lower posterior teeth.
- Satisfied to see a big improvement in the patient's smile.
