Abstract
The present disclosure relates to a dental image processing protocol for the design of dental aligners. Specifically, the dental image processing protocol aids in the determination of tooth movements during realignment, based on an initial position and a final position, and on characteristics of the periodontal environment. Therefore, planned tooth movements reflect both crown movement and root movement within biological structures of the alveolar process.
Claims20
A method for generating an intermediate position of one or more teeth of a dental arch of a patient, comprising:
- classifying, via processing circuitry, pixels of one or more medical images into classes corresponding to biological structure types;
- segmenting, via the processing circuitry, the classified pixels of the one or more medical images into biological structures;
- rendering, via the processing circuitry, a three-dimensional model of the biological structures based on the segmented classified pixels;
- determining, via the processing circuitry, one or more metrics, based upon the three-dimensional model, describing characteristics of a bone of the biological structures;
- acquiring, via the processing circuitry, a final position of each of the one or more teeth of the dental arch based upon the three-dimensional model;
- and
- generating, via the processing circuitry, the intermediate position of each of the one or more teeth of the patient based upon the one or more metrics and the acquired final position.
A non-transitory computer-readable storage medium storing computer-readable instructions that, when executed by a computer having a processing circuitry, cause the computer to perform a method, the method comprising:
- classifying pixels of one or more medical images into classes corresponding to biological structure types;
- segmenting the classified pixels of the one or more medical images into biological structures;
- rendering a three-dimensional model of the biological structures based on the segmented classified pixels;
- determining one or more metrics, based upon the three-dimensional model, describing characteristics of a bone of the biological structures;
- acquiring a final position of each of the one or more teeth of the dental arch based upon the three-dimensional model;
- and
- generating the intermediate position of each of the one or more teeth of the patient based upon the one or more metrics and the acquired final position.
An apparatus for processing of dental images, comprising a processing circuitry configured to:
- classify pixels of one or more medical images into classes corresponding to biological structure types;
- segment the classified pixels of the one or more medical images into biological structures;
- render a three-dimensional model of the biological structures based on the segmented classified pixels;
- determine one or more metrics, based upon the three-dimensional model, describing a bone of the biological structures;
- acquire a final position of each of the one or more teeth of the dental arch based upon the three-dimensional model;
- and
- generate the intermediate position of each of the one or more teeth of the patient based upon the one or more metrics and the acquired final position.
