Referring to FIG. 2, the apparatus 130 for displaying tooth contact information according to the present invention may include a processor 131, a display 132, and an interface 133. The processor 131 may load the patient's tooth data. At this time, the loaded tooth data may be 3D scan data collected through a CT, a 3D scanner, an intra oral scanner, or the like.

In addition, the processor 131 may divide and identify each of the plurality of individual teeth from the loaded tooth data. More specifically, the processor 131 may automatically detect the crown and gums of each of the plurality of individual teeth using the bending information. Alternatively, the processor 131 semi-automatically detects the crown and gums of each of the plurality of individual teeth using feature points, or crowns each of the plurality of individual teeth using crown information directly input by the user through the user interface 133. And the gums can be manually detected. Through the detected crown and gum, the processor 131 may divide and identify each of a plurality of individual teeth from the loaded tooth data, and obtain crown appearance information for each of the individual teeth.

That is, in the outer box, the occlusal surface may be a surface corresponding to the minimum point of the Z axis in the outer shape of the crown. In addition, the mesial surface may be a surface corresponding to the maximum point of the X axis in the crown appearance, and the distal surface may be a surface corresponding to the minimum point of the X axis in the crown appearance. In addition, the buccal surface may be a surface corresponding to the maximum point of the Y axis in the crown appearance, and the tongue surface may be a surface corresponding to the minimum point of the Y axis in the crown appearance. However, such 3D axis information may be changeable depending on the system.
