  • Publication number: 20190343607
    Abstract: To provide a pair of maxillary and mandibular coupled artificial tooth sets applicable to alveolar ridge shapes of an unspecified large number of edentulous patients and having all the parts of 14 teeth coupled into an ideal arch shape and in an ideal maxillomandibular occlusal contact relationship. The present invention provides a pair of maxillary and mandibular coupled artificial tooth sets clearly defining an arrangement region of all parts at the time of arrangement in virtual three-dimensional coordinates, a contact relationship between maxillary and mandibular artificial teeth, and a harmonizing contact/gliding relationship at the time of movement on a mean-value articulator. This enables provision of a high-quality complete denture in which an occlusal relationship required for a complete denture can be established in a short time regardless of a skill of a technician and a difference in shape of an alveolar ridge of an edentulous patient.
