Personalized tooth modeling method

The present invention relates to a personalized tooth modeling method. According to the present invention, it is possible to produce a personalized three-dimensional tooth model similar to a shape of a tooth of an actual patient. The personalized tooth modeling method comprises: a preparation step which prepares a digitized three-dimensional standard tooth model; a first obtaining step which obtains three-dimensional shape data of a crown of a tooth of a patient; a second obtaining step which obtains two-dimensional cross-sectional shape data of the tooth of a patient; a first generation step in which the three-dimensional shape data of the crown of a tooth of a patient and a dental root portion of a standard tooth model are engaged with each other to generate a primary patient tooth model; and a second generation step in which a dental root portion of the primary patient tooth model is modified to be equal to a shape of a dental root portion of the two-dimensional cross-sectional shape data of the tooth of a patient so as to generate a second patient tooth model.
