Effect of Clear Aligner Attachment Size on Extrusion of Maxillary Lateral Incisors
Sponsor: Virginia Commonwealth University
Summary
Orthodontic treatment has been revolutionized by clear aligner therapy, offering patients a more esthetic and comfortable alternative to traditional braces. In 1999, Align Technology introduced Invisalign. As Invisalign has increased in popularity and demand over the past two decades, clinical trials have shed light on the efficacy of Invisalign treatment. there have been changes in the Invisalign protocol such as introduction of SmartForce features in 2008, such as optimized attachments as well as the implementation of SmartTrack aligner material in 2011. Compared to conventional fixed orthodontic appliances, Invisalign cannot be adjusted on a visit-to visit basis. If ideal tooth movement has not been achieved after completion of the first sequence of aligners, additional trays, known as refinement trays, are required.

Superimposition of final and initial positions of lateral incisors: Predicted model
Superimposition of final and initial positions of lateral incisors, two superimpositions will be completed. The pretreatment model will be superimposed with the predicted final model to establish the predicted movement of the maxillary lateral incisors
Superimposition of final and initial positions of lateral incisors: Gingivally beveled 1x1x3mm aligners
Superimposition of final and initial positions of lateral incisors, two superimpositions will be completed. The pretreatment model (Gingivally beveled 1x1x3mm aligners) will be superimposed with the posttreatment model to establish the actual movement of the maxillary lateral incisor.
Superimposition of final and initial positions of lateral incisors: Gingivally beveled 1x1x4mm aligners
Superimposition of final and initial positions of lateral incisors, two superimpositions will be completed. The pretreatment model (Gingivally beveled 1x1x4mm aligners) will be superimposed with the posttreatment model to establish the actual movement of the maxillary lateral incisor.
Superimposition of final and initial positions of lateral incisors: Gingivally beveled 1x1x5mm aligners
Superimposition of final and initial positions of lateral incisors, two superimpositions will be completed. The pretreatment model (Gingivally beveled 1x1x5mm aligners) will be superimposed with the posttreatment model to establish the actual movement of the maxillary lateral incisor.
