The digital superimposition of ridge contour at different time points to accurately evaluate the condition of tissue resorption.
(A) The intraoral frontal views of the residual ridge preoperatively (T0), and at 3 months (T1), 6 months (T2), 12 months (T3), and 24 months (T4) after the first bone augmentation. (B) Superimposing the intraoral scans at T1, T2, T3, and T4 on the initial ridge contour. (C) Superimposing the bone contour at T1, T2, T3, and T4 on initial bone contour. (D) Superimposing the bone contour at T1, T2, T3, and T4 on the ideal bone contour.Six months after the first bone augmentation (T2), soft tissue resorption continued that the titanium mesh can be seen through the overlying gingiva (
