Occlusal adjustment system

A denture occlusal adjustment system, comprising:

• an acquiring unit configured to acquire three-dimensional occlusal-surface shape data and occlusal-surface position data of dentures on a dentist side, the dentures being full dentures including artificial upper teeth configured to be mounted on an upper jaw and artificial lower teeth configured to be mounted on a lower jaw;
• a first transmitter configured to transmit the occlusal-surface shape data and the occlusal-surface position data from the dentist side to a grinding data provider side;
• a reproducer configured to reproduce a maxillomandibular occlusal state on the grinding data provider side from the occlusal-surface shape data and the occlusal-surface position data received from the dentist side;
• a determining unit configured to determine a maxillomandibular occlusal adjustment portion by changing a maxillomandibular occlusal vertical dimension on the grinding data provider side;
• a preparing unit configured to prepare cutting data on the grinding data provider side, the cutting data including the maxillomandibular occlusal adjustment portion, the occlusal-surface position data, and data representative of a grinding surface which extends across an overlapped portion between three-dimensional data of one of the artificial upper teeth and one of the artificial lower teeth, the grinding surface crossing a center of gravity of the overlapped portion;
• a second transmitter configured to transmit the cutting data from the grinding data provider side to the dentist side;
• and
• a performing unit configured to perform an occlusal adjustment on the dentist side by cutting the dentures by a grinding machine based on the cutting data, the occlusal adjustment resulting in a ground surface on each of the artificial upper teeth and each of the artificial lower teeth that meet at a location corresponding to the grinding surface.
