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.
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.
