The present application provides a device for generating a three-dimensional bite pad model, a method for generating a three-dimensional bite pad and a computer storage medium. The three-dimensional bite pad model comprises a base model and a platform model. The device determines a target tooth which is the first tooth of the first jaw to contact the second jaw according to a center relationship, determines a pre-planned bite depth position according to the incisal edge of the target tooth and a pre-planned bite depth value, determines a pre-planned bite plane according to the pre-planned bite depth position and a functional lingual cusp position, and determines a bite contact point on the pre-planned bite plane according to the center relationship. The generated base model has a lingual side which is adjacent to a plurality of teeth arranged in series and including the target tooth. The generated platform model protrudes from the base model towards the lingual side at a position corresponding to the target tooth, has a bite surface on the pre-planned bite plane, and covers the bite contact point.

A method of producing a retention piece having a guidance package configured to provide a desired movement profile including: obtaining data descriptive of mandibular and maxillary arches, an index position of the mandibular arch at a maximum closure position, and a temporomandibular joint of a recipient; specifying an appropriate guidance package based on the desired movement profile; positioning a retention piece comprising at least a portion of the specified guidance package about virtual representations of at least one of the mandibular and maxillary arches within a virtual articulator; modeling relative movement of the virtual representations of the mandibular and maxillary arches within the virtual articulator; and generating data that can be used by a computer aided machining (CAM) process to create at least one physical retention piece comprising the specified guidance package configured to provide the desired movement profile.

The present invention relates to a fixator (10) for fixing a first tooth model (52) and a second tooth model (54), wherein the fixator (10) has a first fixator-side guide element (28) and a second fixator-side guide element (30), both of which extend in a longitudinal direction (12) of the fixator (10), wherein the first fixator-side guide element (28) can be coupled to a first model-side guide element (62) of the first tooth model (52) and the second fixator-side guide element (30) can be coupled to a second model-side guide element (64) of the second tooth model (54), wherein the first fixator-side guide element (28) is configured to guide the first model-side guide element (62) in the longitudinal direction (12) when the first fixator-side guide element (28) is coupled to the first model-side guide element (62), and wherein the second fixator-side guide element (30) is configured toto guide the second model-side guide element (64) in the longitudinal direction (12) when the second fixator-side guide element (30) is coupled to the second model-side guide element (64). Furthermore, the present invention relates to a system (50). Furthermore, the present invention relates to a method (100) for fixing a first dental model (52) and a second dental model (54) by means of at least one fixator (10).

The present invention relates to an intraoral scanner for acquisition of the natural position of the head, three-dimensional orientation of the occlusal plane position and facial aesthetic references, and in order for it to achieve this objective the intraoral scanner (3) incorporates a device that allows the acquisition of information, said device being a level, which may be a double bubble level (4), of the patient's natural position of the head as well as the three-dimensional spatial orientation of the occlusal plane and its transfer to the digital articulators, with the respective data acquisition protocol.

Certain aspects of the present disclosure provide for a method of determining a virtual occlusion. The method may include obtaining a 3-D representation of a patient's first and second jaw portions. The method may further include, with the 3-D representation, representing in a GUI an initial position of the first jaw portion relative to the second jaw portion, the initial position being defined by six pre-determined degrees of freedom relative to a coordinate system fixed relative to the first jaw portion. The method may further include receiving user input of changes at least one degree of freedom, and automatically adjusting at least one other degree of freedom to minimize a vertical distance of the control point to the origin, thereby determining a virtual occlusion. The method may further include representing, in the GUI, the first and second jaw portions in the determined virtual occlusion.
