Device and method for measuring a movement of a mandible

A system for recording, transferring and simulating a relative position and/or relative movement, measured at a patient, of a mandible relative to a maxilla of the patient, comprising:

• a transmitter coil for emitting a magnetic measurement field, wherein the transmitter coil is disposable in extraoral fashion to the side or above the maxilla in a position fixed in place with respect to the maxilla;
• at least one holding device with a position marker for at least one first sensor;
• the at least one first sensor configured to be attached to the mandible of the patient, the at least one first sensor disposed in the at least one holding device;
• a sensor positioning device for setting a reference plane relative to the transmitter coil with condyle points, the sensor positioning device comprising a sensor tip of at least one second sensor for setting the reference plane, wherein at least the sensor tip of the sensor positioning device is introducible into the position marker of the at least one holding device;
• and
• a computer for recording, processing and presenting relative movement from a data record of the first and second sensors generated from sensor signals of the at least one first sensor and from position data of the sensor positioning device with respect to the reference plane, wherein three-dimensional imaging of a motion sequence is implemented by fusing the position data and movement data obtained during a motion sequence of the mandible relative to the maxilla.
