Mandibular Sequential Distalization Versus Class III Elastics With Clear Aligners in Class III Patients

"Lower Distalization Protocol included extraction of the lower third molars before starting treatment and a 50% sequential lower distalization with two teeth being distalized at a time. The distalization started with the movement of lower second molars, followed by the first molars halfway through the process, and so on. Once the canine reached the right position, the en masse retraction of the four incisors completed the treatment plan. The protocol comprised the use of Class III intermaxillary elastics to support the distalization movement and to control the proclination of lower incisors"

Non-Distalization Protocol featured extraction of the lower third molars before starting treatment, transversal dento-alveolar coordination, strategic interproximal reduction (IPR) in the anterior segment of the lower arch, and the addition of Class III elastics
