Abstract
The systems and methods disclosed herein provide real time display of three-dimensional dental data acquired intraorally from a dental patient.
Claims22
A method comprising:
- acquiring two dimensional data from one or more intraoral structures of a dental patient at a video rate;
- reconstructing a digital surface representation of the one or more intraoral structures;
- displaying the digital surface representation at the video rate;
- acquiring additional two-dimensional data from the one or more intraoral structures in a subsequent frame of data at the video rate;
- reconstructing a subsequent digital surface representation from the additional two-dimensional data at the video rate
- combining the digital surface representation and the subsequent digital surface representation at the video rate to provide a three-dimensional representation of the one or more intraoral structures;
- providing a visual display of the three-dimensional representation at the video rate in real time;
- and
- providing a visualization within the visual display, the visualization updated at the video rate to identify regions of inaccurate scan data within the three-dimensional representation.

A computer program product embodied on a non-transitory computer readable medium that, when executing on one or more computing devices, performs the steps of:
- acquiring two dimensional data from one or more intraoral structures of a dental patient at a video rate;
- reconstructing a digital surface representation of the one or more intraoral structures;
- displaying the digital surface representation at the video rate;
- acquiring additional two-dimensional data from the one or more intraoral structures in a subsequent frame of data at the video rate;
- reconstructing a subsequent digital surface representation from the additional two-dimensional data at the video rate
- combining the digital surface representation and the subsequent digital surface representation at the video rate to provide a three-dimensional representation of the one or more intraoral structures;
- providing a visual display of the three-dimensional representation at the video rate in real time;
- and
- providing a visualization within the visual display, the visualization updated at the video rate to identify regions of inaccurate scan data within the three-dimensional representation.

A system comprising:
- a scanner for acquiring a sequence of image sets from one or more intraoral structures of a dental patient at a video rate;
- and
- a processor configured to:
- receive one of the sequence of image sets,
- convert the one of the sequence of image sets into a three-dimensional surface representation of the one or more intraoral structures,
- combine the three-dimensional surface representation with one or more prior three-dimensional surface representations from one or more prior ones of the sequence of image sets to provide a three-dimensional model of the one or more intraoral structures, and
- generate a visual display signal of the three-dimensional model at the video rate in real time,
- generate a visualization within the visual display signal, the visualization updated at the video rate to identify regions of inaccurate scan data within the three-dimensional representation;
- and a display for displaying the visual display signal.
