A dental tray appliance system including a maxillary tray appliance and optionally a mandibular tray appliance. The maxillary tray appliance includes a first base portion, a first premolar tooth form, optionally a first contacting portion, optionally a contralateral first premolar tooth form, and optionally a central incisor tooth form. Each premolar tooth form has no lingual cusp as part of improvements in occlusal registration components. The mandibular tray appliance includes a second base portion, optionally a second contacting portion; and optionally a second bite material accepting portion.

Disclosed is a method for scanning an edentulous patent who has a denture, where an impression material arranged at the gum-facing surfaces of the dentures is shaped by the patient's gums and both the teeth side and the gum-facing surface of the denture is scanned and the obtained digital 3D representations are used to determine the relative arrangement of the patient's edentulous jaws in a bite determined by the dentures.

To provide try-in dentures which make it possible to adjust a bite more easily with high accuracy, a denture base part 12; a dentition part 13; an adjustment part 15; and a base part 14 are included, the adjustment part and the base part being separable from each other, and the adjustment part includes all of occlusal surfaces 13b of the dentition part, and a face 15a parallel to an occlusal plane 10a, the adjustment part being formed so that a movement of the adjustment part parallel to the occlusal plane with respect to the base part can be performed, a rotation of the adjustment part in the face parallel to the occlusal plane can be performed, or both the movement and the rotation can be performed.

The invention relates to methods for digitally designing artificial teeth for use in a dental prosthesis and/or dental restoration. Methods of designing natural-looking, functional artificial teeth, based on computer-aided design, utilize reference dentition articulated in a predetermined occlusal scheme as a basis for effective design. In particular, the occlusal surfaces of posterior artificial teeth are designed in a digital environment to provide effective, consistent functional set-up and performance, especially across a variety of occlusal schemes, in the preparation of dental prostheses.

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.
