Methods and systems for modeling mandibular motion

A system for modeling mandibular motion, the system comprising:

• at least one interface device;
• and
• an electronic device including a processor,
• the processor being configured for executing method steps including:
• acquiring a point cloud representing a mandible of a subject;
• determining an initial condyle pose of each of a right condyle of the mandible and a left condyle of the mandible;
• determining a plurality of natural movement parameters for each of the right condyle and the left condyle;
• receiving, from a user via an interface of the electronic device, at least one indication of at least one movement of the mandible;
• determining a natural movement of the mandible based on the at least one indication of the at least one movement and at least in part on the plurality of natural movement parameters, the determining the natural movement including at least one of (i) a protrusion of the mandible followed by a first sagittal inclination of the mandible, and (ii) a Bennet movement of the mandible followed by a second sagittal inclination of the mandible;
• applying the natural movement to the point cloud to form a transformed point cloud;
• generating a model of the mandible having undergone the at least one movement using the transformed point cloud;
• and
• displaying the model of the mandible having undergone the at least one movement.
