A landmark is displayed on the antagonist model included in the lateral cross-section according to the vertical position, and a landmark is displayed on the occlusal surface of the antagonist model according to the horizontal position of the landmark included in the antagonist model. An output unit for correcting and displaying the lateral cross-section, the occlusal surface of the work surface model, and the occlusal surface of the antagonist model according to the corrected working value model
Occlusal relationship implementation apparatus comprising a. The method of claim 7, wherein
The landmark is,
Cusp Tip, Occlusal Point and Center (Groove or Fissure), Marginal Ridge, and Ancisal Edge and Occlusal Point of Marginal Teeth Marginal Ridge) occlusion relationship implementation device comprising at least one. The method of claim 7, wherein
The processor,
Identify the location of fossa and cusp of the antagonist from the landmark information included in the antagonist model, and the fossa, cusp and marginal ridge of the working model in the tooth library. Determine the location and height of the cusp and marginal ridges of the working tooth model according to the location of the fossa of the antagonist, and determine the location and height of the cusps of the working model according to the location of the cusp of the antagonist. Occlusal relationship implementation device that determines the position and height. The method of claim 7, wherein
The processor,
Check whether the movement command of the landmark is in the occlusal or cervical direction, and if the movement command of the landmark is in the occlusal or cervical direction, do not move the landmark;
The output unit,
An occlusion relationship implementing device that outputs a non-moveable message of the landmark.
