Abstract: This case report demonstrates that using Clear Aligners (CA) in conjunction with a modified C-palatal plate (MCPP) for distalizing the maxillary arch can be an efficient approach for treating malocclusions. This method is compared to CA therapy alone, which would require a higher number of aligners, interproximal enamel reduction (IPER), and a longer treatment time for the same amount of movement. A female patient with skeletal and dental Class I relationships and bimaxillary protrusion was treated. Orthodontic records were taken, and a palatal retraction arch (PRA) was bonded to the right and left maxillary first molars. After activating the MCPP, the aligners were used. Orthodontic force was applied to the teeth immediately after the distalization of the molars. The total treatment time was 15 months. The patient’s soft tissue profile improved after distalizing the maxillary arch using CA with MCPP and the mandibular arch using mini-implants. This case report suggests that using CA with MCPP may be advantageous in severe malocclusion cases requiring significant tooth movement.
