Maxillary expansion with bone-borne and tooth-borne expanders was analyzed. Bone-borne expansion produced posterior displacement and decreased net displacement. Stresses concentrated around the miniscrews. Tooth-borne expansion enhanced the effect of maxillary protraction. The facemask alone produced more anterior displacement of the maxilla.
