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.
