Abstract
The invention provides a method for creating a physical teeth model. The method comprises the following steps: providing a virtual three dimensional (3D) representation of a patient's dentition that comprises at least a region of the teeth that includes a tooth stump on which a crown is to be fitted or a region on to which a bridge is to be fitted; and preparing a physical model of the jaws of a subject from a blank, based on information from said virtual 3D image.
Claims30
A system for generating a physical model for dental treatment, the system comprising:
- a processor operably coupled to a computer readable storage medium comprising instructions which, when executed, cause the processor to:
- generate a first 3D digital model of a first dental arch of a patient;
- generate a second 3D digital model of a second dental arch of a patient;
- generate a 3D digital data of the first dental arch and second dental arch in occlusion;
- and
- determine a spatial relationship of the first 3D digital model of the first dental arch and the second digital mode of the second arch based on the first 3D model, the second 3D model, and the 3D digital data;
- output to a CAM apparatus to produce the physical model based on the first 3D model, the second 3D model, and the spatial relationship.
A method of generating a tooth model for dental treatment, the method comprising:
- imaging a first dental arch of the patient to generate a first 3D digital model of the first dental arch of a patient;
- imaging a second dental arch of the patient to generate a second 3D digital model of a second dental arch of a patient;
- imaging the first dental arch and second dental arch in occlusion;
- and
- determining a spatial relationship of the first 3D digital model of the first dental arch and the second 3D digital model of the second arch based on the imaging of the first dental arch and the second dental arch in occlusion.
A method of generating a tooth model for dental treatment, the method comprising:
- generating a first 3D digital model of the first dental arch of a patient;
- generating a second 3D digital model of a second dental arch of a patient;
- generating 3D digital data of the first dental arch and second dental arch in occlusion;
- and
- determining a spatial relationship of the first 3D digital model of the first dental arch and the second 3D digital model of the second arch based digital data of the first dental arch and second dental arch in occlusion.
