Claim Text:
1. A method for determining a grinding portion of pre-grinding dentures of maxillomandibular artificial teeth, the method comprising: providing the pre-grinding dentures of maxillomandibular artificial teeth which have a grinding portion to be formed into an occlusal surface by grinding, and three or more reference points disposed on the grinding portion; placing the pre-grinding dentures of maxillomandibular artificial teeth in a synthetic resin; providing an articulator having an upper arch and a lower arch, each of the upper arch and the lower arch having three or more reference points; reading the reference points of the pre-grinding dentures of maxillomandibular artificial teeth placed in the synthetic resin; producing a three dimensional data of the pre-grinding dentures of maxillomandibular artificial teeth in a computer based on the read reference points of the pre-grinding dentures of maxillomandibular artificial teeth; reading the reference points of the articulator; producing a three dimensional data of the articulator in the computer based on the read reference points of the articulator; calculating in the computer a position of the pre-grinding dentures of maxillomandibular artificial teeth mounted on the articulator so as to reproduce an occlusion state in the computer; and determining the grinding portion at a location where three dimensional data of the pre-grinding dentures of maxillomandibular artificial teeth overlap with each other.
