What does appliance prescription refer to?

• A. The archwire length
• B. The angulation and torque values built into the bracket
• C. The bonding method
• D. The patient age

Answer: (B)

The key idea is that appliance prescription is about the built-in specifications in brackets that guide how a tooth should move once the archwire is in place. Specifically, it defines the angulation (the mesio-distal tilt) and the torque (the bucco-lingual root inclination) that each bracket is designed to produce. These values control how the tooth tips and how the root tilts during treatment, shaping the final alignment. Other factors like the archwire length, bonding method, or patient age don’t establish these bracket-based movement goals.
