This article has described the process for tooth alignment
using 3D thin plate spline. First step is to simulate the
individual tooth and its landmarks and fit it into the dental
cast by geometric transformation of individual tooth.
Next step is to align the simulated teeth into proper arch
form. After that, record pairs the landmarks of simulated
teeth before and after tooth alignment. The final step is to
create the new dental cast (warping dental cast) by
applying 3D thin plate spline technique through pairs of
landmarks on simulated teeth as inputs. The results of the
tooth alignment and the comparison with the dental cast
before tooth alignment have shown that the teeth aligned
along the curve while the gum was slightly deformed to
show the smoothness of transformation on teeth and gum.
