Mandible position indicator for analyzing bite function

摘要

A system and method for modeling bite function. A top pantograph is fixed to a patient via clutches to the top teeth of the patient, a bottom pantograph is fixed to a patient via clutches to the bottom teeth of the patient and the actual bite of the patient is optically monitored by monitoring the relation of the top pantograph to the bottom pantograph during a bite cycle and storing a hinge axis. Data is stored relating to the actual bite and the top teeth are scanned to create a top teeth model while the bottom teeth are scanned to create a bottom teeth model. A digital representation of the top pantograph is digitally fitted to the top teeth, a digital representation of the bottom pantograph bottom pantograph is digitally fitted to the bottom teeth, and the relationship of the top teeth model and the bottom teeth model to the hinge axis is recorded. A bite model is digitally created by recording the position of the top teeth model in relation to the bottom teeth model while digitally moving the bottom teeth model with respect to the top teeth model around the hinge axis.

1. A method, comprising:
fixing a top pantograph to a patient via clutches to the top teeth of the patient; fixing a bottom pantograph to a patient via clutches to the bottom teeth of the patient; optically monitoring the actual bite of the patient by monitoring the relation of the top pantograph to the bottom pantograph during a bite cycle; storing bite data relating to the actual bite; storing patient data including a three-dimensional model including a top teeth model and a bottom teeth model; storing a digital top pantograph model associated with the top pantograph; storing a digital bottom pantograph model associated with the bottom pantograph; digitally pairing the bite data, the top pantograph model and the bottom pantograph model to the patient data; and digitally modeling the bite by digitally moving the bottom teeth model with respect to the top teeth model in association with the stored bite data.
