Outline of Final Research Achievements	This study was performed to predict three-dimensional model of normal lower first molar on partial least squares regression. The object data selected 11 cases without the metal arch fact of CT data.And, And, we reconstructed three tooth model (lower second pre molar, first molar, second molar) by CT data. It was evaluated by Average Symmetric Surface Distance (ASD) with the error of the estimated shape and correct answer shape. As a result, the ASD error of the leave-one-out intersection inspection was 0.60+-0.17 (mean±std) mm.
