This project aims at estimating the complete 3D representation of a tooth given only the crown. The technique is based on the use of statistical model derived from 3D-images of 22 premolars reconstructed by micro-CT. The root is constructed by matching the respective crowns of the two models, defining the optimal registration, and optimizing the statistical model parameters. This method allows us to generate the root efficiently with a small number of parameters to adjust.
