Abstract
Methods and systems for generating a three-dimensional occlusogram are disclosed. One method includes determining a virtual three dimensional (3D) mesh model object of at least one tooth of a patient and displaying the determined virtual 3D mesh model object of at least one tooth of a patient wherein the 3D mesh model object includes a plurality of data sets associated with a set of occlusal information for the at least one tooth of the patient.
Claims20
A non-transitory computing device readable medium having executable instructions which can be executed by a processor to cause a computing device to perform a method, comprising:
- determining a plurality of data sets associated with a set of occlusal information for at least one tooth of a patient, wherein determining a data set includes calculating an average occlusal distance of at least one triangle of a three dimensional (3D) mesh of the at least one tooth using at least one of a height map and a distance field of the at least one tooth;
- determining a virtual 3D mesh model object of the at least one tooth using the plurality of data sets;
- and
- displaying the determined virtual 3D mesh model object of the at least one tooth of a patient.
A non-transitory computing device readable medium having executable instructions which can be executed by a processor to cause a computing device to perform a method, comprising:
- determining a plurality of data sets associated with a set of occlusal information for at least one tooth of a patient, wherein determining a data set includes calculating an average occlusal distance of at least one triangle of a three dimensional (3D) mesh of the at least one tooth using at least one of a height map and a distance field of the at least one tooth;
- determining a virtual 3D mesh model object of the at least one tooth using the plurality of data sets;
- and
- simulating a dental treatment process using the virtual 3D mesh model object of the at least one tooth.
A computing system, comprising:
- a memory having executable instructions stored thereon;
- and
- a processor coupled to the memory and configured to execute the instructions to:
- determine a plurality of data sets associated with a set of occlusal information for at least one tooth of a patient, wherein determining a data set among the plurality of data sets includes instructions executed to:
- map nodes from a surface grid of the at least one tooth to a three dimensional (3D) mesh of the at least one tooth to form a rectangular 3D mesh of the tooth;
- split at least one rectangle in the rectangular 3D mesh along a diagonal into two triangles;
- and
- calculate an average occlusal distance of the at least one triangle using at least one of a height map and a distance field of the at least one tooth;
- determine a virtual 3D mesh model object of the at least one tooth using the plurality of data sets;
- and
- display the determined virtual 3D mesh model object of the at least one tooth of the patient.
