The invention relates to an additive method for producing a dental working model (1) for an articulator (2), comprising the steps: additively producing a base plate (3, 3a, 3b) for attachment to the articulator (2), and additively producing a dental model (4, 4a, 4b), wherein the base plate (3, 3a, 3b) and the dental model (4, 4a, 4b) are configured to be fixed to one another in a positionally secure manner. Another object of the invention is an additively produced dental working model (1) for an articulator (2), comprising an additively produced base plate (3, 3a, 3b) configured for attachment to the articulator (2), and an additively produced dental model (4, 4a, 4b), wherein the base plate (3, 3a, 3b) and the dental model (4, 4a, 4b) are configured to be fixed to one another in a positionally secure manner.

The invention provides a method for creating a physical teeth model. The method comprises the following steps: providing a virtual three dimensional (3D) representation of a patient's dentition that comprises at least a region of the teeth that includes a tooth stump on which a crown is to be fitted or a region on to which a bridge is to be fitted; and preparing a physical model of the jaws of a subject from a blank, based on information from said virtual 3D image.

An articulator having a maxillary member and a mandibular member, which are connected to each other via condylar articulations, wherein a maxillary adaptor is attachable or attached at the maxillary member and a mandibular adaptor at the mandibular member, wherein a maxillary alignment member especially is form-fittingly connected to the maxillary adaptor and a mandibular alignment member is especially form-fittingly connected with the mandibular adaptor, and wherein the alignment members are automatically alignable to each other and comprising scanning members, by means of which the arrangement of alignment members and adaptors is scannable in a scanner and especially the relative position thereof moreover is detectable in relation to the articulator via the scanner.

An apparatus includes a dental model coupling portion and a base plate adapter coupling portion. The dental model coupling portion is configured to couple with a dental model. The base plate adapter coupling portion includes a body and a set of prongs extending from the body. The body is fixedly secured relative to the dental model coupling portion. The prongs are configured to removably secure the base plate adapter coupling portion to a base plate adapter of a dental model articulator. A base plate adapter includes a first side and a second side opposite the first side. The first side is configured to removably couple with the base plate adapter coupling portion. The second side is configured to removably couple with a dental model articulator.

A dental articulator (10) includes a lower base (12) having two support arms (28) extending therefrom. Each support arm (28) includes an upper end with an opening (30) therein. Each opening (30) is adapted to receive a fixed-angle temporomandibular joint assembly (32) having a fixed horizontal condyle angle or an adjustable-angle temporomandibular joint assembly (34) having an adjustable horizontal condyle angle. A dental articulator kit may initially include only a pair of fixed-angle temporomandibular joint assemblies (32) with the pair of adjustable-angle temporomandibular joint assemblies (34) available to be acquired by a user at a later time.

The present invention is concerned with an apparatus for simulating the chewing process for the purpose of testing dental materials and implants and for the purpose of analyzing food samples. The apparatus comprises a frame, a stationary platform connected compliantly to the said frame and a moving platform corresponding to the maxillae and mandible of humans or animals, to which dentures or teeth are affixed. The moving platform is guided and driven in mandibular motion using six rods fitted with spherical joints at both ends. Said ball-jointed rods are attached with one end to the moving platform, and with the other end either to the frame of the apparatus, or to rotary cranks driven synchronously by a motor via a transmission. The rotary cranks together with their motor and transmission are mounted on a carrier which is adjustably attached to the frame of the apparatus. To closely reproduce a desired mandibular motion, the locations of the spherical joints to the frame, the position and orientation of the carrier relative to the frame, and the lengths of the rotary cranks and of the ball-jointed rods are suitably adjusted.

A method for virtually designing the attachment of a manufactured dental model of a patient's set of teeth in a physical dental articulator by one or more kinds of spacer elements, where the method includes obtaining a virtual 3D dental model, providing a virtual dental articulator, where the height of the dental model is the height of an upper part and the height of a lower part of the dental model; providing one or more kinds of virtual spacer elements with predetermined heights, determining a manufacture height of the dental model and determining the number of each of the kinds of spacer elements to be used for the attachment of the manufactured dental model in the physical articulator, such that the manufacture height of the dental model and the total effective spacer element height, equals the articulator height.
