3.9.2 Condyle position measurement (CPM)
A condyle position measurement (CPM) describes the measurement of the 3-dimensional offset in the
joint between a reference position and any another joint position (e.g. maximum intercuspation ICP).
Naturally, measurements of a position relative to the occlusion (e.g. ICP) only make sense if the
registration clutch is fixed to the lower jaw teeth in para-occlusal method.
Before performing a measurement, ensure that the patient is in reference position. In the ideal
case, the red cross of the real-time cursor is positioned exactly in the origin of the coordinate
system. If this position is difficult to reproduce, you can re-set the software's reference position
via the button of the same name (refer to chapter "Setting the reference position
").
To start a CPM registration, press the corresponding
button on the left border of the window.
Guide the patient into reference position (re-set it, if ne-
cessary) and have them move to the second position to
be measured. Press the foot switch to measure this pos-
ition.
Each measurement is signaled acoustically. The system
allows performing up to ten measurements.
To delete a measurement, right-click the item in the list to bring up the context menu and choose De-
lete .
You can rename the individual measurements by right-clicking them in the list and choosing
