System and method for fabricating a dental restoration

1. A system for fabricating a dental restoration to restore a tooth at a restoration site in a dentition of a patient, wherein the dentition includes a restoration dental arch and an opposing dental arch, the restoration dental arch including the restoration site and the opposing dental arch being opposite the restoration dental arch, the system comprising:

an impression apparatus configured to capture an impression of at least a portion of the dentition of the patient including the restoration site;

a motion capture apparatus configured to generate relative motion data from optical measurement of movement of the opposing dental arch relative to the restoration dental arch as the dentition moves between a plurality of bite positions;

a functional bite map apparatus configured to generate a functional bite map representing bite registration information for a plurality of bite positions of the dentition of the patient;

a design system comprising:

at least one processing device; and

at least one memory device comprising computer readable instructions that, when executed by the processing device, perform operations comprising:

generating, with an interference model generation system, an interference model for the restoration site, based on the dental impression, the functional bite map, and the relative motion data, wherein the interference model includes an interference surface corresponding to the locations of the opposing dental arch in at least a portion of the plurality of the bite positions;

receiving a restoration prescription; and

designing the dental restoration, using the interference model and the restoration prescription, wherein the dental restoration does not interfere with the interference surface.

2. The system of claim 1 , wherein the dental impression is a digital impression generated by an intraoral scanner.

3. The system of claim 1 , wherein the dental impression is a digital impression generated by scanning a physical impression of the dentition of the patient.

4. The system of claim 1 , wherein the optical measurements are extracted from image data or video data recorded of the dentition of the patient as the restoration dental arch and the opposing dental arch move relative to one another.

5. The system of claim 1 , wherein the optical measurements are extracted from image data or video data of one or more devices secured to a portion of the dentition of the patient as the restoration dental arch and the opposing dental arch move relative to one another.

6. The system of claim 1 , wherein generating the interference surface further comprises:

generating a digital model of the opposing dental arch from the dental impression;

sweeping the digital model along a movement path captured with the motion data; and

extracting the interference surface opposing the restoration site.

7. The system of claim 1 , wherein the operations further comprise:

displaying, on a user interface, a graphical display of the interference model; and

receiving input from a user at the user interface to design the dental restoration data.

8. The system of claim 1 , wherein the restoration prescription defines an identity of the tooth to be restored and a type of restoration to be fabricated.

9. The system of claim 1 , further comprising a restoration fabrication apparatus configured to fabricate the dental restoration, based on the dental restoration data and interference model.
