Comments

Sequential Distalization was used to create space for relief of crowding and improve protrusive teeth
Expansion and IPR protocols help 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
Happy to see good outcome of patient's smile
