3.2. Functional principle of JMA-Optic system
The JMA-Optic system is a 3D coordinate measuring system. It consists of a facebow (receiver
and control unit), the mandibular sensor (transmitter unit) and an optional charging station.
The optional charging station is also used to store the system and is used for inductive charging
of the batteries built into the facebow. The mandibular sensor is powered by a battery button
cell. It contains 12 LEDs that are activated during measurement by an infrared signal from the
facebow. During a measurement, the movements of the sensor - attached to the lower teeth -
are recorded by the cameras integrated in the facebow.
The position of the luminous points of the LEDs are determined by the two cameras in the
facebow and sent to the PC via USB connection or optionally via Wifi connection.
The PC uses this data to determine the position of the mandibular sensor relative to the face-
bow. The application software on the PC is used to store and analyze the measurement data.
