A simulation method of jaw movement comprising: a superimposing process step of reading dentition configuration data and jaw movement data, calculating a coordinate transformation matrix for matching a coordinate system of the dentition configuration data with a coordinate system in a jaw movement basic state in the jaw movement data, and transforming the dentition configuration data to coordinates on the coordinate system in the jaw movement basic state to obtain superimposed dentition configuration data; and a simulation process step of calculating superimposed dentition configuration data in another jaw movement state and superimposedly displaying a dentition configuration diagram obtained by converting the superimposed dentition configuration data to an image and a jaw movement state diagram obtained by converting the jaw movement data to an image.
