A difficult and sometimes overlooked procedure in orthodontic treatment is to fabricate a custom arch wire to deliver additional torque. A wire twist does not equate to torque force delivered. Appliance prescription, tooth emergence angle, and desired tooth movement are factors to consider when fabricating a custom arch wire. This lecture will provide the attendee practical information as to how to add the correct amount of wire twist to provide the desired torque. A step by step wire bending format will be used. Each attendee is welcome to bring two orthodontic bending pliers, a marking pen, and an 18 x 25 arch blank. Easy to understand concepts will be demonstrated and the design of a custom fabricated arch wire with the prescribed third order bends will be made.
Measure and fabricate a custom arch designed to deliver the prescribed torque.
Recognize prescribed arch wire bending is more accurate and efficient, and eliminates the need for torqueing auxiliaries.
Demonstrate a better understanding as to how to insert an active third order arch wire.
