Abstract
The article considers comparison of the outcomes of surgically assisted rapid palatal expansion with the use of tooth-borne and bone-borne expansion appliances in patients with transversal maxillary deficiency. 76 computed tomography scans of 38 patients (24 with bone-borne anchorage, 14 with tooth-borne ones) were studied. Examination of the expansion was performed before the treatment onset and after the activation of the screw of the distraction apparatus. Expansion was evaluated in the areas of canines, premolars and first molars. The maximal amount of the vestibular tooth crown inclination was revealed in premolars with tooth-borne appliances. The use of bone-borne appliances allows to achieve the greatest effect of tooth body shift in a vestibular direction.
