A method for registering a tooth image with a tooth structure according to an embodiment includes a first registering step for registering a tooth image model obtained from a medical image taken when an object bites a bite including a marker with a bite scanning model obtained by scanning the bite, a second registering step for registering the bite scanning model with a tooth scanning model obtained by scanning a tooth shape of the object, and a third registering step for registering the tooth image model with the tooth scanning model based on the results of the first registering step and the results of the second registering step. As a result, a model including an accurate shape of tooth part difficult to obtain from a medical imaging apparatus can be easily obtained.
