how should a treatment be staged?

Answer 5

2. decide on treatment in lower (non extraction or extraction?)

4. decide on molar relationship class 1 or full unit class 2

Question 6

What should you look out for when examining the lower arch?

Answer 6

• crowding
• Angulation of canines
• Curve of Spee

* Angulation of canines

Answer 8

• Incisor relationship

• OB
• Centrelines
• Canine relationship
• Molar relationship

Question 9

Answer 9

Space available - space required = discrepancy
