The present invention relates to methods and systems for generating a 3-D dental impression with a corresponding hinge axis position and, in certain embodiments, a condylar guide inclination. In some embodiments, an intraoral scanner and a computer processing system are employed to: i) generate upper and lower jaw models, and first and second occlusal 3-D models with different mouth openings (MOs) or functional positions (FPs), ii) align the models to generate a composite 3-D model, iii) calculate a hinge axis position from the composite 3-D model based on the difference in said MOs or FPs, and iv) mount the 3-D dental impression on a virtual articulator (VA) by aligning the hinge axis position to the hinge axis position of the VA.

Reciprocal positions of negative casts (2, 3) upper and lower dental arches, of a subject (S) recipient of a dental prosthesis (1), by means of an attitude detection device (40).

These positions are then transferred to a manual articulator (50) to be able to positionpositive models (20, 30) of the same upper and lower dental arches with a dentation model form for a dental prosthesis (1).

Using a column template (6), (50) adjustments are detected and brought back to an articulator robot (90), operated by actuators (94).

Chewing movements of the subject (S) are video-taped and digitized, so that a program generator (80) provdes a sequence of commands for driving the robot to move the models (20, 30) to replicate mandibular movements of the subject (S) so as to enable evaluation of correctness of the dentation model form, and possibly modify.

The disclosed technology provides for setting up teeth, such as dentures and dental appliances, based on motion data. A method can include receiving, by a computing system, a digital representation of the patient's jaw movement, receiving a digital model of at least a portion of the patient's upper and lower teeth, receiving user input indicating selection of at least a first tooth in the digital model as moveable, at least a second tooth as fixed, and at least a third tooth as ignored, moving the at least portion of the upper teeth and the lower teeth along movement pathways indicated by the digital representation of jaw movement, and automatically adjusting a position of the selected first tooth based on detecting the position of the selected at least first tooth as colliding or interfering with one or more other teeth represented by the digital model along one of the movement pathways.

The present invention is a device for simulating lower jaw activity. The device can be utilized in cooperation with an artificial intelligent lower jaw occlusion and attitude recording device. The device comprises a base, an upper jaw tooth mold, an opening and closing rotating platform, a left and right rotating platform, a horizontal rotating platform, a front-back shifting platform and a lower jaw tooth mold. The present invention makes it possible to make lower jaw moving forward and backward, opening and closing (pitch), tilting left and right (yaw), in place rotating (yaw), and etc. Then, according to the data obtained by the artificial intelligent lower jaw occlusion and attitude recording device, the lower jaw activities concluded through the reverse engineering by means of the present invention facilitates production of accurate intra-oral device, and can be applied to unknown complex actions in dental medical research, such as occlusion, bruxism, swallowing, sounding, and etc.

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.
