Apparatuses, components, devices, methods, and systems for generating dentures are provided. An example system includes a motion capture system that captures patient jaw motion and generates patient jaw motion data; and a denture design system that generates a denture design based on the patient jaw motion data. An example method includes acquiring a digital reference denture model of a reference denture; selecting a denture tooth library based on the digital reference denture model; selecting and aligning denture library teeth from the selected denture tooth library to the digital reference denture model; generating a denture base digital model based on the digital reference denture model and the aligned denture library teeth; and fabricating a physical denture based from the denture base digital model.

Digital denture design and replacement

Apparatuses, components, devices, methods, and systems for determining and tracking movement are provided. An example apparatus that includes a position indicating system having a first light emitter positioned and oriented to emit light in a first direction, a second light emitter positioned and oriented to emit light in a second direction, the second direction being collinear with and opposite to the first direction; and a third light emitter positioned and oriented to emit light in a third direction, the third direction being different than the first direction and the second direction. The third direction may be offset from the first direction by an offset angle that is an acute angle. The apparatus may also include a screen; an imaging system configured to capture an image of the screen. The first light emitter and the third light emitter may both be configured to emit light toward the screen.

Determining and tracking movement

Apparatuses, components, devices, methods, and systems for determining jaw movement are provided. An example patient assembly for capturing motion data of a patient includes a clutch configured to be worn by the patient on a dentition of the patient. The clutch includes a dentition coupling device configured to couple to the dentition of the patient and includes an extension member configured to protrude out from the patient's mouth. The clutch also includes a position indicating system rigidly connected to the dentition coupling device. An example position indicating system emits a plurality of light beams. Some examples also include an imaging system and a motion determining device. An example imaging system captures a plurality of image sets that each include at least one of a plurality of screens upon which the light beams project. An example motion determining device processes the captured image sets to determine the motion of the patient's dentition.

Determining jaw movement

A rock crushing assembly is provided in the form of a pulverizing tumbler. The apparatus includes a faceted tumbler having a plurality of faceted end walls, a pair of parallel sidewalls, and an open interior. A power source and a drivetrain assembly attach to the sidewalls of the tumbler and rotate the same. Within the tumbler is adapted to be placed rocks and minerals to be pulverized, wherein pulverizing media is placed in the tumbler with the rocks to break down the rocks into fine, granular material. One of the end walls of the tumbler is removable to allow access to the tumbler interior. One or more gaps or apertures through one or more of the end walls allow the pulverized material to exit the tumbler during operation, thereby reducing build-up of loose material that can dampen impacts within the tumbler.

Pulverizing apparatus and method of pulverizing rocks

An electronic 3D model of at least a portion of a maxillary arch of a patient is displayed. Inputs indicating a tip of a mesiobuccal cusp of a maxillary first molar are received for both the patient's right and left sides. In addition, an electronic 3D model of at least a portion of a mandibular arch of a patient is displayed. Inputs indicating relevant points on the mandibular first molar are received for both the patient's right and left sides. Side scores are generated for the patient's right and left sides based on the indicated points. A final occlusion score for the patient is displayed. The final occlusion score is based on the side score for the right side and the side score for the left side.

Dental occlusion analysis tool

A technique for fabricating a surgical splint for use in correcting a dental condition of a patient. The technique involves obtaining a three-dimensional digital model of lower and upper arch dentitions of the patient having the dental condition. Relative positions of the lower and upper arch dentitions are adjusted with respect to each other in the three-dimensional digital model using a computing device. A relative positioning structure is added to the three-dimensional digital model using the computing device. A physical model of the patient's corrected dentition is then generated from the three-dimensional digital model. The physical model includes the relative positioning structure that connects the lower and upper arch dentitions of the physical model at the adjusted relative position. The surgical splint is then formed using the physical model. A non-surgical splint is also described.

Fabrication of maxillofacial surgical splints

An electronic 3D model of at least a portion of a maxillary arch of a patient is displayed. Inputs indicating a peak of a mesiobuccal cusp of a maxillary first molar are received for both the patient's right and left sides. In addition, an electronic 3D model of at least a portion of a mandibular arch of a patient is displayed. Inputs indicating relevant points on the mandibular first molar are received for both the patient's right and left sides. Side scores are generated for the patient's right and left sides based on the indicated points. A final occlusion score for the patient is displayed. The final occlusion score is based on the side score for the right side and the side score for the left side.
