Description

For the past 20 years, clear aligner therapy has become more popular in orthodontics. However, extrusion of anterior teeth to establish a consonant smile arc has been unpredictable at best. During this presentation, the force vectors associated with anterior extrusive movements will be resolved and a dependable, predictable extrusion attachment and staging protocol with clinical examples will be presented.

Learning Objectives:

• Evaluate the force vectors on anterior teeth when using clear aligner therapy.
• Discern the need for reciprocal attachments when attempting extrusion of anterior teeth.
• Demonstrate clinical examples of attachment and staging protocols for predictable success.
