  • Patent number: 11793614
    Abstract: A method for manufacturing a denture includes: preparing an artificial tooth and a denture base with a concave socket; applying an adhesive to the concave socket; and embedding the artificial tooth in the concave socket to which the adhesive is applied. A socket groove is defined on an inner surface defining the concave socket. The socket groove extends from a concave bottom surface of the concave socket facing a basal surface of the artificial tooth to a lingual concave side surface of the concave socket. Embedding the artificial tooth in the concave socket includes: forming a discharge hole to discharge the adhesive, the discharge hole being defined at an end of the socket groove on a lingual outer surface of the denture base; and discharging the adhesive from the discharge hole.

  • Patent number: 11284976
    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.

  • Patent number: 8128404
    Abstract: It is intended to provide artificial teeth designed to easily enable bilateral balanced occlusion with less grinding adjustment. According to the present invention, angles formed by occlusal facets of the artificial teeth with an occlusal plane are suitably set. An artificial tooth for maxillary central incisor, for example, has a protrusive facet and a retrusive facet on an incisal edge thereof. Of angles formed by the protrusive facet with the occlusal plane, the angle in cross section along a sagittal plane is 22.0° to 25.5°, and the angle in cross section along a coronal plane is 1.5° to 6.5°. Of angles formed by the retrusive facet with the occlusal plane, the angle in cross section along the sagittal plane is 20.5° to 23.0°, and the angle in cross section along the coronal plane is 1.5° to 6.5°.
