A facebow-free transfer method includes: registering virtual upper and lower casts respectively to an upper teeth part of a virtual maxilla model and a lower teeth part of a virtual mandible model so as to form a virtual teeth and jaw model; mounting the virtual teeth and jaw model on a virtual articulator; generating a virtual occlusion transfer module that is mounted on the virtual articulator and that has a part extending to and fitting in an in-between space of virtual upper and lower casts of the virtual teeth and jaw model; and creating an actual occlusion transfer device that is to be mounted on an articulator based on the virtual occlusion transfer module.

Provided is an instrument capable of performing maxillomandibular registration after an occlusal vertical dimension is accurately registered in the oral cavity of a patient. With the use of these instruments in the oral cavity, maxillomandibular registration can be performed and a prosthesis can be produced in a state where occlusal stability is reproduced by point contact. Further, with the use of an articulator capable of reproducing the shape and movement of the mandible, a prosthesis can be produced regardless of the experience of the operator.

The invention relates to a system for recording, transferring and simulating a relative position and/or movement, measured on a patient, of a mandible (UK) relative to a maxilla (OK) of the patient, comprising: a transmitter coil (8) for transmitting a magnetic measurement field (5), wherein the transmitter coil (8) can be arranged extra-orally laterally or above the maxilla (OK) in a fixed position in relation to the maxilla; at least one sensor (9) placed on the mandible (UK) of the patient and arranged in at least one holding device (3) having a position marking (5) for the sensor (9) a sensor positioning device (13) provided for setting the axis-orbital plane and condylar points and comprising at least one sensor (11) for capturing and emitting positional data which can be introduced into the position marking (5) of the holding device (3); a data set of a relative movement, measured on a patient, of a mandible (UK) relative to a maxilla (OK) of the patient, the data set is generated from the sensor signals of the at least one sensor (9) arranged on the mandible (UK) of the patient and from the positional data from the sensor signals from the sensor positioning device (7); and a computer for recording, processing and displaying the movement data from the data set from the sensor(s) (7, 9), the fusion of the position and movement data producing a three-dimensional image of the movement sequence and enabling the therapeutic positions or functions to be controlled. The invention relates to a corresponding method for recording, transferring and simulating a relative position and/or movement, measured on a patient, of a mandible (UK) relative to a maxilla (OK) of the patient.

Disclosed is a method for determining the relative arrangement of patient's jaws in a bite position when the patient's occlusion is not defined by natural teeth alone, where the method includes a step of obtaining a digital 3D representation including both surface data relating to dental tissue in one of the patient's jaws and surface data relating to a scan appliance arranged in relation to the jaw, where the scan appliance is configured for at least partly defining the patient's occlusion.

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.

The dental measurement device can include a vertical orientation rod to align with a sagittal midline reference plane a patient. The dental measurement device can also include a baseline orientation frame coupleable to the vertical orientation rod to align with one or more of an eye feature and an ear feature of the patient to define a horizontal reference plane of the patient. The dental measurement device can further include a bite plate configured to be held in a mouth of the patient. In addition, the dental measurement device can include a nose extension arm for coupling the bite plate to the vertical rod. A dental prosthetic manufacturing system for use with an articulator is disclosed that can utilize the dental measurement device to create a dental prosthetic. A reference tool for modeling a dental prosthetic is also disclosed.

A tool for 3D adjustment of a muscle position used at the adjustment of a jaw position is provided with a first member attached in a position corresponding to left and right molar regions, including a plurality of convex parts and a second member attached to a position opposing at least the first member, wherein the first member has a surface facing the second member provided with a plurality of convex parts, the convex parts having distal ends capable of sliding on an upper surface of the second member, and the second member has a surface facing at least the first member, the surface being a substantially flat surface. By using the articulator for 3D adjustment of a muscle position, the occlusal position is caused to correspond to the centric occlusal position with good accuracy, making it possible to produce a prosthetic appliance.

The invention relates to a method for animating models of the mandibular and maxillary arches of a patient in a corrected intermaxillary relationship, comprising: providing three-dimensional numerical models (MD, MX) of the mandibular and maxillary arches of the patient; providing a recording of the mandibular motion of the patient, said recording comprising a plurality of relative positions of the mandible of the patient with respect to the maxilla; selecting, from said positions, a reference position (X) of the mandible with respect to the maxilla of the patient; determining a target position (Y) for the mandible with respect to the maxilla, said target position defining a corrected intermaxillary relationship for the patient; determining a rigid transformation between the reference position (X) and the target position (Y); applying said rigid transformation (i) to the recording of the mandibular motion of the patient in order to animate the three-dimensional numerical models of the mandibular and maxillary arches, or (ii) to the three-dimensional numerical model of the mandible, the delivered recording of the mandibular motion being applied to the three-dimensional numerical models of the mandible and of the maxilla in order to animate said models.

The present invention may comprise a method for a treatment plan for orthodontic movement of natural teeth, the method comprising of acquiring data of oral anatomy of a patient; creating a treatment plan for the patient for orthodontic movement of natural teeth, the end result of the treatment plan for the patient being a 3D model; printing out a physical model of 3D model; mounting the physical model of the maxillary arch and mandibular arch of the patient's oral anatomy onto a dental articulator to evaluate if at least one of the following exists: if the functional occlusion data of the patient is in centric relation or if malocclusion exists between the maxillary arch and the mandibular arch; applying any corrections to the 3D model from the step of determining if malocclusion exists, to create functional occlusion data; combining the functional occlusion data with data of the oral anatomy of the patient to create a virtual treatment solution; and creating orthodontic appliances from the virtual treatment solution, whereby at least one of the above steps is accomplished without the need for human interaction.
