Abstract

This session explores advanced clinical strategies for enhancing orthodontic outcomes in adult patients using clear aligners. It focuses on the selective application of trim lines and buttons to optimize force systems, retention, and tooth movement predictability. Clinical indications, biomechanical principles, and evidence-based decision-making are discussed, providing practitioners with practical insights for managing complex adult cases efficiently.

Learning Objectives

• Identify when to use different trim line designs to optimize aligner retention and force delivery.
• Understand the biomechanical role of buttons and elastics in controlling complex tooth movements.
• Determine case selection criteria for adult patients requiring auxiliary features.
• Apply evidence-based strategies for integrating trim lines and buttons into aligner treatment plans
