Augmented reality enhancements for intraoral scanning

A method comprising:

• receiving a plurality of intraoral images of a patient from an intraoral scanner during an intraoral scanning procedure;
• generating, by a computing device, a virtual three-dimensional model of at least a portion of a dental arch from the plurality of intraoral images during the intraoral scanning procedure;
• receiving additional image data from an augmented reality (AR) display comprising one or more lenses, wherein the additional image data is representative of a field of view of a wearer of the AR display;
• determining, from the additional image data, a first region of the field of view that includes the dental arch and a second region of the field of view that does not include the dental arch;
• generating, by the computing device, a visual overlay of the virtual three-dimensional model;
• and
• sending the visual overlay of the virtual three-dimensional model to the AR display, wherein the AR display is to superimpose the visual overlay of the virtual three-dimensional model over a real-world environment in the field of view of the wearer that the wearer sees through the one or more lenses such that the visual overlay of the virtual three-dimensional model is superimposed over the real-world environment in the second region of the field of view and the visual overlay of the virtual three-dimensional model is not superimposed over the real-world environment in the first region of the field of view that includes the dental arch.

A non-transitory computer readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving a plurality of intraoral images of a patient from an intraoral scanner during an intraoral scanning procedure;
• generating, by the processing device, a virtual three-dimensional model of at least a portion of a dental arch from the plurality of intraoral images during the intraoral scanning procedure;
• receiving additional image data from an augmented reality (AR) display comprising one or more lenses, wherein the additional image data is representative of a field of view of a wearer of the AR display;
• determining, from the additional image data, a first region of the field of view that includes the dental arch and a second region of the field of view that does not include the dental arch;
• generating, by the processing device, a visual overlay of the virtual three-dimensional model;
• and
• sending the visual overlay of the virtual three-dimensional model to the AR display, wherein the AR display is to superimpose the visual overlay of the virtual three-dimensional model over a real-world environment in the field of view of the wearer that the wearer sees through the one or more lenses such that the visual overlay of the virtual three-dimensional model is superimposed over the real-world environment in the second region of the field of view and the visual overlay of the virtual three-dimensional model is not superimposed over the real-world environment in the first region of the field of view that includes the dental arch.
