Abstract
Methods and systems are described that use a three-dimensional (3D) model of a dental site to generate a panoramic two-dimensional (2D) image of the dental site. In one example, a method includes receiving a 3D model of the dental site generated at least in part from an intraoral scan, generating a surface shaped to substantially surround a dental arch represented by the dental site, computing a surface projection by projecting the dental site onto the surface, and generating the panoramic 2D image from the surface projection.
Claims25
A method comprising:
- receiving a three-dimensional (3D) model of a dental site generated from one or more intraoral scans;
- generating a projection target shaped to substantially surround an arch represented by the dental site;
- computing a surface projection by projecting the 3D model of the dental site onto one or more surfaces of the projection target;
- and
- generating at least one panoramic two-dimensional (2D) image of the dental site from the surface projection.
A method comprising:
- receiving a three-dimensional (3D) model of a dental site generated from one or more intraoral scans;
- generating a plurality of vertices along an arch represented by the dental site;
- computing a projection target comprising a plurality of surface segments connected to each other in series at locations of the vertices;
- scaling the projection target with respect to an arch center located within a central region of the arch such that the projection target substantially surrounds the arch;
- computing a surface projection by projecting the 3D model of the dental site onto each of the surface segments of the projection target;
- and
- generating at least one panoramic two-dimensional (2D) image of the dental site from the surface projection.
A method comprising:
- receiving a three-dimensional (3D) model of a dental site generated from one or more intraoral scans;
- generating a projection target shaped to substantially surround an arch represented by the dental site;
- computing a first surface projection by projecting the 3D model of the dental site onto one or more surfaces of the projection target along a buccal direction;
- computing a second surface projection by projecting the 3D model of the dental site onto one or more surfaces of the projection target along a lingual direction;
- and
- generating at least one panoramic two-dimensional (2D) image by combining the first surface projection and the second surface projection.
A system comprising:
- a memory;
- and
- a processing device to execute instructions from the memory to perform a method comprising:
- receiving a three-dimensional (3D) model of a dental site generated from one or more intraoral scans;
- generating a projection target shaped to substantially surround an arch represented by the dental site;
- computing a surface projection by projecting the 3D model of the dental site onto one or more surfaces of the projection target;
- and
- generating at least one panoramic two-dimensional (2D) image of the dental site from the surface projection.
