  • Patent number: 10631877
    Abstract: Disclosed is a method of simulating mastication. The method includes obtaining computer-readable three-dimensional representations of a first skeletal fragment including a portion of at least one of a mandible and a maxilla and of a recipient skeletal fragment including a portion of at least one of a mandible and a maxilla. The method also includes obtaining placement data and obtaining muscle insertion data. The method also includes simulating a contraction of a muscle positioned according to the muscle insertion data in a representation of a surgical hybrid comprising at least a portion of the first skeletal fragment positioned according to the placement data relative to at least a portion of the recipient skeletal fragment. The method also includes outputting a representation of mastication represented by the simulating.

  • Publication number: 20170000504
    Abstract: Provided herein is a computer-implemented method, system, computer-readable medium operable to perform the method for cephalometry for orthognathic and craniomaxillofacial surgery. The method can include transforming a set of cephalometric landmarks from a donor or mobile skeletal fragment in a first reference frame to a second reference frame based on a registration process that maps coordinates from the first reference frame to coordinates in the second reference frame; tracking movement, based on one or more signals from one or more sensors, during surgery, of one or more of the cephalometric landmarks in the set of cephalometric landmarks associated with the donor or mobile skeletal fragment with respect to one or more of the cephalometric landmarks in the set of cephalometric landmarks associated with a recipient or second skeletal portion in the second reference frame; calculating one or more cephalometry metrics; and providing an update of the one or more cephalometry metrics.
