Modified transpalatal arch to correct sagging of palatal cusp of maxillary 2nd molar
“Sagging” of the palatal cusp of upper second molars is a common finding observed during orthodontic treatment which may develop heavy balancing side contacts, which have been found to be detrimental to harmonious function of the masticatory system. Various modifications of transpalatal arch (TPA) are advocated to correct crossbite, but most of them will utilize an additional step of soldering a wire attachment to TPA. In this clinical pearl, the TPA was fabricated using a single wire component, eliminating an additional step of soldering.
