Palatal expansion used to correct maxillomandibular transverse discrepancies occurs through a combination of skeletal orthopedic expansion, which involves separating the maxilla at the midpalatal suture, and dental orthodontic expansion, which results from buccal tipping of the maxillary posterior teeth. The proportion of skeletal and dental movement is dependent on the rate of expansion rapid or slow and the age of the patient during treatment. A The goal of palatal expansion is to maximize the skeletal movement and to minimize the dental movement, while allowing for physiological adjustment of the suture during separation.
