Transverse expansion with in-office aligners

Nowadays, aligner orthodontics offers a range of treatment possibilities for almost every type of malocclusion. The latest developments in software and printers provide practitioners with options for altering aligner margins, material stiffness and thickness, and other key aspects in aligner orthodontics like direct printed aligners. Covering the palate and using aligners with longer margins instead of scalloped aligners and torque elements in aligner therapy increases the biomechanical force transferred onto the posterior teeth and enables the practitioner to improve predictability when widening the arches without major loss of crown torque. The present article describes the treatment of two patients with in-office aligners and coverage of the maxillary palate.
