Application of 3D Computed Tomography Reconstruction Images to Assess the Thickness and Dimensions of the Posterior Palatal Seal Area

Figure 2

Model was divided and thickness of mucosa was measured at 93 points. (a) Seven sections parallel to coronal plane at 2mm intervals from HN line. (b) 15 sections parallel to sagittal plane at 3mm intervals from mid-palatal line to both sides. (c) 93 crossing points of each divided plane. IP, incisive papilla; HN, hamular notch.
