Virtual dental articulator
A system and method for creating a model of a patient's mandible and any teeth supported from the mandible and manipulating the mandible relative to anatomical features of the patient's maxilla. The system uses markers positioned on the mandible and on the maxilla to create a functional mandibular axis that approximates an axis through the condyles of the patient. The functional mandibular axis and geometric and anatomical information about the patient's upper and lower jaw are then used to create prostheses for the patient. The system is also used for making corrections to the prosthesis.
