Digital scan body alignment using library data
A system for intraoral scanning comprises a scanner to generate image data of a dental site and a computer readable medium. The computer readable medium includes instructs that, when executed by a processing device, cause the processing device receive a selection of library data for a reference object from library data for a plurality of reference objects in a library, receive the image data generated by the intraoral scanner, the image data comprising a representation of a dental site comprising the reference object, and align the library data for the reference object with the image data.

receive the image data generated by the intraoral scanner, the image data comprising a representation of a dental site comprising a first portion of the scan body reference object;
align the library data for the scan body reference object with the first portion of the scan body reference object in the image data;
generate a virtual three-dimensional (3D) model of the scan body reference object, the virtual 3D model comprising the first portion of the scan body reference object; and
supplement the virtual 3D model of the scan body reference object by adding an unscanned portion of the scan body reference object based on alignment of the library data for the scan body reference object with the first portion of the scan body reference object in the image data.
2 . The system of claim 1 , wherein the instructions further cause the processing device to:
generate a virtual 3D model of the dental site based on the image data and the library data, the virtual 3D model of the dental site comprising a 3D representation of the scan body reference object as depicted in the virtual 3D model of the scan body reference object.
3 . The system of claim 1 , wherein the instructions further cause the processing device to:
output the virtual 3D model of the scan body reference object, comprising information from the library data and information from the image data, to a display.
4 . The system of claim 3 , wherein the processing device is further to:
output, to the display, guidance indicating additional images to be captured.
5 . The system of claim 4 , wherein the guidance identifies one or more regions of the scan body reference object that would benefit from capture of the additional images.
6 . The system of claim 1 , wherein the image data comprises three-dimensional (3D) intraoral scan data.
7 . The system of claim 1 , wherein the library data comprises known shape information for the scan body reference object.
8 . The system of claim 7 , wherein aligning the library data with the image data comprises matching the known shape information for the scan body reference object from the library data with shape information from the image data.
9 . The system of claim 1 , wherein the scan body reference object is made of a material that is difficult to image.
10 . The system of claim 9 , wherein the material that is difficult to image is titanium.
11 . A system comprising:
an intraoral scanner to generate image data of a dental site; and
a computing device configured to:
receive the image data of the dental site, the image data comprising a representation of the dental site and a representation of a first portion of a scan body reference object at the dental site;
select library data for the scan body reference object from library data for a plurality of scan body reference objects in a library;
align the library data for the scan body reference object with the image data;
generate a virtual three-dimensional (3D) model of the scan body reference object, the virtual 3D model of the scan body reference object comprising the first portion of the scan body reference object; and
supplement the virtual 3D model of the scan body reference object by adding an unscanned portion of the scan body reference object based on alignment of the library data for the scan body reference object with the image data.
12 . The system of claim 11 , wherein the computing device is further to:
search through the plurality of scan body reference objects in the library to identify that the representation of the scan body reference object in the image data matches a model of the scan body reference object in the library data for the scan body reference object, wherein the library data for the scan body reference object is automatically selected responsive to a determination that the representation of the scan body reference object matches the model for the scan body reference object in the library data for the scan body reference object.
13 . The system of claim 11 , wherein the computing device is further to:
receive user input indicating the library data for the scan body reference object, wherein the library data for the scan body reference object is selected responsive to receipt of the user input.
14 . The system of claim 11 , wherein the computing device is further to:
generate a virtual 3D model of the dental site based on the image data and the library data, the virtual 3D model of the dental site comprising a 3D representation of the scan body reference object as depicted in the virtual 3D model of the scan body reference object.
15 . The system of claim 11 , wherein the computing device is further to:
output the virtual 3D model of the scan body reference object, comprising information from the library data and information from the image data, to a display.
16 . The system of claim 11 , wherein the image data comprises three-dimensional (3D) intraoral scan data.
17 . The system of claim 11 , wherein the library data comprises known shape information for the scan body reference object.
18 . The system of claim 17 , wherein aligning the image data with the library data comprises matching the known shape information for the scan body reference object from the library data with shape information from the image data.
