Abstract
A method for generating a mapping of dental occlusion generates a three-dimensional model of the patient's teeth according to acquired image data. The maxillary and mandibular arches are positioned in opposition in the generated model of the patient's teeth and a meal model generated having characteristics of a foam material. A pressure field distribution for the generated meal model is calculated for one or more pairs of opposed teeth from the generated three-dimensional model of the patient's teeth. The calculated pressure field distribution can be displayed.

A method for generating a mapping of dental occlusion, the method comprising:
- generating a three-dimensional data model of a plurality of teeth of definition according to acquired image data;
- positioning maxillary and mandibular arches in opposition in the generated data model of the plurality of teeth;
- generating a data model having characteristics of a foam material;
- calculating a pressure field distribution for the generated data model for one or more pairs of opposed teeth from the generated three-dimensional data model of the plurality of teeth;
- and
- storing at least a portion of the calculated pressure field distribution.
A method for generating a mapping of dental occlusion of a patient's teeth, the method comprising:
- generating a three-dimensional data model of a subject's teeth;
- positioning maxillary and mandibular arches in opposition in the generated data model of the subject's teeth;
- calculating one or more distances between occlusal surfaces of opposed teeth according to the maxillary and mandibular arch positioning;
- generating a data model having characteristics of a foam material;
- calculating a pressure field distribution for the generated data model for one or more pairs of opposed teeth according to the generated data model of the subject's teeth and according to the one or more calculated distances between occlusal surfaces;
- and
- transmitting at least the calculated pressure field distribution for one or more of the teeth.
A method for generating a mapping of dental occlusion, the method comprising:
- generating a three-dimensional data model of a patient's teeth using one or more casts or impressions of the patient's maxillary and mandibular arches and using digital image data from the one or more casts or impressions;
- positioning the maxillary and mandibular arches in opposition in the generated data model of the patient's teeth;
- calculating one or more distances between occlusal surfaces of opposed teeth according to the maxillary and mandibular arch positioning;
- generating a data model having characteristics of a foam material;
