Abstract
An intraoral scanner system includes an intraoral scanner having an imaging device and a sensing face, and a computing device, communicatively coupled to the intraoral scanner. The computing device receives a first intraoral images of a three-dimensional intraoral object of a patient generated by the intraoral scanner corresponding to an intraoral scanning of the three-dimensional intraoral object of the patient. The computing device registers a first intraoral image of the first intraoral images relative to a second intraoral image of the first intraoral images using a model of the three-dimensional intraoral object that existed prior to the intraoral scanning.
Claims21
An intraoral scanner system comprising:
- an intraoral scanner comprising an imaging device and a sensing face;
- and
- a computing device, communicatively coupled to the intraoral scanner, to:
- receive a first plurality of intraoral images of a three-dimensional intraoral object of a patient generated by the intraoral scanner corresponding to an intraoral scanning of the three-dimensional intraoral object of the patient;
- and
- register a first intraoral image of the first plurality of intraoral images relative to a second intraoral image of the first plurality of intraoral images using a model of the three-dimensional intraoral object that existed prior to the intraoral scanning performed during a previous patient visit.
A non-transitory computer-readable medium comprising instructions that, responsive to execution by a processing device, cause the processing device to perform operations comprising:
- receiving a first plurality of intraoral images of a three-dimensional intraoral object of a patient generated by an intraoral scanner corresponding to an intraoral scanning of the three-dimensional intraoral object of the patient;
- and
- registering a first intraoral image of the first plurality of intraoral images relative to a second intraoral image of the first plurality of intraoral images using a model of the three-dimensional intraoral object that existed prior to the intraoral scanning performed during a previous patient visit.
A method, comprising:
- receiving a first plurality of intraoral images of a first portion of a three-dimensional intraoral object of a patient generated by an intraoral scanner corresponding to an intraoral scanning of the three-dimensional intraoral object of the patient;
- and
- registering a first intraoral image of the first plurality of intraoral images relative to a second intraoral image of the first plurality of intraoral images using a model of the three-dimensional intraoral object that existed prior to the intraoral scanning performed during a previous patient visit.
