Figure 3

Thickness of mucosa was measured and displayed in color, and the PPS area was determined. (a) Color map of thickness and the PPS area border line. (b) Diagram of vertical plane of the PPS area. P0, rearmost point of anterior border; P1, foremost point of anterior border of right side; P2, foremost point of anterior border of left side; RW, dimension between P1 and mid-palatal line; LW, dimension between P2 and mid-palatal line; OD, dimension between P0 and hamular notch line; RD, dimension between P1 and hamular notch line; LD, dimension between P2 and hamular notch line.
