Fig. 1From: 3D evaluation of the morphological and volumetric changes of the tongue and oral cavity before and after orthognathic surgery for mandibular prognathism: a preliminary studyMethodology flow chart. An alginate impression was taken to make a customized impression tray. The impression of the upper and lower dental arches in occlusion, together with the tongue, and the palate were taken using VPS impression paste. Then, VPS impression pattern was scanned by cone-beam CT, and the DICOM data was obtained. The 3D images of the oral cavity including the tongue were reconstructed from the DICOM data. Observation of tongue morphology and measurements of OCC and TV were performedBack to article page
