Abstract
The study aimed to evaluate, via a cone beam computed tomography the skeletal changes produced by surgically assisted rapid maxillary expansion. MTD is frequently observed in patients who seek orthodontic treatment and is often characterized by unilateral or bilateral crossbite as well as anterior crowding.There are different treatment approaches, depending on the skeletal maturity, the amount of desired expansion and the presence of a concomitant sagittal or vertical problem.In adult patients, the RME without surgical assistance might lead to considerable stresses developing at the bony structures of the cranial base and the mid-face. SARME has become a widely used and acceptable mean to expand the maxilla in adolescents and adult patients. The method takes advantage of bone formation at the maxillary edges of the midline, while they are separated by an external force. The theory behind the rapid activation is that the force applied to the teeth would be transmitted to the bone and the two halves of the maxilla would separate before a significant tooth movement could occur. Rapid activation was indicated as a wa Various surgical procedures have been developed for SARME in proportion to the primary areas of resistance in the craniofacial skeleton.The areas of resistance have been classified as anterior support (piriform aperture pillars), lateral support (zygomatic buttresses), posterior support (pterygoid junctions), and medial support (mid-palatal suture)
