Fig. 02 The 3D construction of the area

Fig. 03 A 5 mm slice shows the roots seem to biolating the cortical bone of the alveolar housings

Fig. 05 The coronal view with a slice taken through the lingual roots of the maxillary first molars can be used to accurately determine the width of the maxilla and the inclinations of the maxillary molars

Fig. 6a Since no bands were attached to the molars, true horizontal expansion was achieved

Fig. 6b Since no bands were attached to the molars, true horizontal expansion was achieved

Fig. 6c Since no bands were attached to the molars, true horizontal expansion was achieved
