Occlusal vertical dimension reproduction method for manufacturing artificial teeth

An occlusal vertical dimension reproduction method for denture fabrication, the method comprising:

• operation (a) of obtaining edentulous jaw shape information, which is shape information of an edentulous state of at least one of upper or lower jaws of a patient;
• operation (b) of obtaining denture shape information, which is shape information of a denture structure having a corresponding shape so as to engage with one of the patient's upper and lower jaws in an edentulous state;
• operation (c) of obtaining occlusion shape information, which is shape information of the denture structure when the upper and lower jaws are in occlusion while the patient is wearing the denture structure on an edentulous jaw;
• operation (d) of aligning and arranging corresponding surfaces of the edentulous jaw shape information and the denture shape information with the occlusion shape information in a state in which the corresponding surfaces are aligned with each other;
• and
• operation (e) of calculating a positional relationship between the upper and lower jaws in a state in which the edentulous jaw shape information, the denture shape information, an d the occlusion shape information are aligned by the operation (d).
