    摘要： A dental model gripping system can include a dental model and a dental model gripper. The dental model can include a replica set of teeth and a flat bottom surface there beneath that can include first and second vertical openings spaced apart by an opening distance. The dental model gripper can have a flat top surface and first and second pins extending vertically therethrough that can slide toward and away from each other. The first and second pins can be slid to an engaging position where they are spaced apart by the opening distance and are insertable into the vertical openings of the dental model, can be slid away from each other to a gripping position while inserted into the vertical openings, and can press against internal surfaces within the vertical openings to grip firmly the bottom surface of the dental model against the top surface of the dental model gripper.

    摘要： Disclosed is a computer-implemented method of using a dynamic virtual articulator for simulating occlusion of teeth, when performing computer-aided designing of one or more dental restorations for a patient, where the method includes the steps of: providing the virtual articulator including a virtual three-dimensional model of the upper jaw and a virtual three-dimensional model of the lower jaw resembling the upper jaw and lower jaw, respectively, of the patient's mouth; providing movement of the virtual upper jaw and the virtual lower jaw relative to each other for simulating dynamic occlusion, whereby collisions between teeth in the virtual upper and virtual lower jaw occur; wherein the method further includes: providing that the teeth in the virtual upper jaw and virtual lower jaw are blocked from penetrating each other's virtual surfaces in the collisions.

    摘要： Provided is a dental model in which a model tooth having a root portion similar to an actual tooth is attachable to and detachable from a gum portion, and an articulator. A dental model 1 according to the present disclosure includes: a gum portion 12 in which an insertion hole 20 to which a model tooth 50 is to be inserted is provided; and a lid portion 18 provided on an oral side of the insertion hole 20 in the gum portion 12, in which the lid portion 18 constitutes a part of the gum portion 12 in a closed state, and provides a recess portion 18b that is continuous from the insertion hole 20 and exposes at least a part of a root portion of the model tooth in an opened state, and in which the lid portion 18 is configured to be opened and closed relative to another portion of the gum portion 12.

    摘要： The invention relates to a device (1) for measuring a relative position and/or movement of a mandible (UK) relative to a maxilla of a patient, comprising an emitting coil (8) for emitting an electromagnetic measuring field (5), at least one mandible sensor (US1), said mandible sensor (US1) being placed and/or can be placed on teeth in the mouth (U1-U8) or in the mouth on a mandible device (UK). The mandible sensor (US1) is designed as a sensor at least for determining a position in a measuring field (5) and/or relative to the emitting coil (8), also comprising an evaluation device (3) for determining the relative position and/or relative movement of the mandible (UK) relative to the maxilla (OK) based on positions determined by the sensor (US1). The sensor coil (8) is placed and/or can be placed outside of the mouth on the side or above the maxilla (OK). The invention also relates to a method for determining a relative position and/or movement of the mandible (UK) relative to a maxilla (OK) of a patient with a device (1), a device (X) for simulating and transferring a measured relative movement from the method and a holding device for at least one maxilla sensor (OS1) and/or at least one mandible sensor (US1).

    摘要： The device for recording centric jaw relation and orientation jaw relation simultaneously is disclosed that provides an accurate and precise recording of centric jaw relation as well as orientation jaw relation recording and transfer. The device includes a central bar, a centric relation recorder, a dentulous adjustable fork or an edentulous fork, a semi-circular frame, a nasion pointer and an orbital pointer. The central bar is received by a plurality of clamping assemblies that adjustably position the nasion pointer, the adjustable fork or the edentulous fork and the centric relation recorder respectively. The device can be used in case of both, dentulous as well as edentulous subjects. The device can advantageously transfer the centric relation record to any semi-adjustable articulators or non-adjustable articulators.

    摘要： A method for digitally designing a denture for a patient, where the denture includes a plurality of denture teeth, where designing the denture includes transforming the denture, and where the denture teeth are grouped in at least two blocks where each block includes at least two denture teeth. The method includes obtaining a 3D scan of the upper jaw and lower jaw of the patient; obtaining a digital 3D arrangement of the denture teeth, where the denture teeth are pre-set in occlusion; digitally arranging the 3D scan of the upper jaw and lower jaw relative to the 3D arrangement of the denture teeth; and digitally transforming at least one denture tooth based on input from a user; where at least one design rule is enforced that affect one or more, but not all of the blocks, when the at least one denture tooth is transformed.
