TAD Mechanics for Fixed Appliances and Aligners

This presentation will analyze and compare the similarities and differences of biomechanics design in TAD application for fixed appliances and aligner system. Specific types of cases, including deepbite, impaction and gummy smile correction will be provided for further illustration and case demonstration.

Learning Objectives:

• Differentiate the biomechanics of TADs for fixed appliance and aligners.
• Propose strategies to incorporate TADs into aligner treatment to strengthen its clinical efficacy.
• Identify various screw placement positions and techniques for both fixed appliance and aligners.
