Single-tooth modeling results of 3D dental model with normal tooth arrangement. (a) The initial 3D dental model. (b) Minimum curvature color map. (c) Separation results shown as a whole corresponding to the initial 3D dental model. (d) After the fusion regions being deleted. (e) After single-tooth shape being restored. (f) Separation results corresponding to the 3D dental model after shape restoration. (g) The separated tooth in (c) displayed, respectively. (h) The separated tooth in (f) displayed, respectively.
