• Align upper and lower teeth

• Achieve class I molar and canine relationship

• Midline shift correction

• A stable Overjet and overbite

Results and conclusion posttreatment

Resolved the crowding, Class I canine and molar relationship, stable overjet and overbite. Midline shift correction. Distalization was applied while using Class II elastics throughout the treatment. Decrowding with the aid of IPR. Adjusting the Overjet and overbite.
