A method for automatically aligning a model for an upper jaw with a model for a lower jaw, the method including forming models for teeth of the upper jaw and the lower jaw based on images obtaining a reference bite frame with the teeth in a clenched state aligning the models for the teeth of the upper jaw and the lower jaw with the reference bite frame, respectively, to determine transform information between the generated models and the reference bite frame aligning the model for the teeth of the upper jaw with that of the lower jaw based on the determined transform information.
