An occlusal state correction-supporting apparatus, a program therefor, and a recording medium thereof are provided, which can generate necessary, effective information in order to complete the shape of teeth excellently bitten. A shape-extracting means 10 extracts and stores shaped data of an upper jaw and a lower jaw. A position-extracting means 20 extracts and stores absolute coordinate data of reference points. A condition setting and distance-computing means 30 computes the distance between a upper jaw model 100 and a lower jaw model 200 while gradually bringing them close in a perpendicular direction. The condition setting and distance-computing means 30 also sets a condition of occlusal contact point, executes such approach movement again, and computes the distance. A correction area and amount-determining means 40 obtains information through a operator's operation, which indicates that desired occlusal state has been obtained, and determines the correction area and the correction-amount based on the occlusal state of the upper jaw and the lower jaw at that time.
