Comments
- This is a Class II div 1 subdivision case with mid line deviation to R't side.
- Tx plan is to extract 1.4 (UR4), 2.4(UL4), 3.4(LL4), 4.5(LR5), for profile improvement and relieve crowding.
- Asymmetrical ext over lower arch made mid line and molar relationship correction easier.
- Anterior retraction is done by G6 protocol.
