The JMA-Optic system should be periodically checked by the user for
proper operation to ensure patient safety on a permanent basis.
After hard knocks, or if the face bow or lower jaw sensor has fallen
to the floor, a recalibration by the manufacturer must be performed
to ensure system high accuracy.
In the case of recognizable damage to system components (deforma-
tion, dents, cracks), no further recordings may be made.
If the surfaces of the IR filter discs on the JMA-Optic face bow and / or
lower jaw sensor are scratched, use is prohibited. Correct results can
not be guaranteed.
In order to guarantee the high accuracy of ± 0.05 mm (x, y, z)
permanently, the JMA-Optic system should be recalibrated at the latest
after 3 years by the manufacturer.

7.2. Checking the measurement function
■
To inspect the system, for known jaw functioning measurements (e.g. known maximum
opening width, known condylar range of motion with protrusion, known horizontal condylar
guidance inclination), the user can measure himself with the measurement system.
These measurement results should correspond with the known values.
■
When the sensors do not move, the software should show an unmoving image of
the lower jaw. Possible deviations (spikes or jumps in the measurement curve in spite of unmoved
markers, incorrect presentation of the lower jaw, etc.) indicate a faulty measurement and impair
the evaluation.
■
Should there be any doubts about the measurement accuracy, re-calibration of the JMA-Optic
system by the manufacturer is recommended in order to ensure the specified accuracy.
