In this paper, the authors present a fuzzy normal estimate for mass point clouds of irregular models in reconstruction. The irregular model is complex object that some part is smooth and some parts are irregular including sharp features. Therefore, they put kNN and curvature of mass point clouds to fuzzy inference system to divide the kind of point clouds and the output of FIS (Fuzzy Inference System) can determine which part of tooth point clouds belong to. For different kinds point clouds, corresponding algorithm is given.
