Jaw Measurement Analysis System<br />
<strong>The</strong> <strong>zebris</strong> JMA measuring system for contact-free<br />
recording<strong>of</strong>allthelowerjaw,functionsusinga<br />
new type <strong>of</strong> ultrasonic sensor technology measuring<br />
in the proximity <strong>of</strong> the joint.<br />
<strong>The</strong> extremely light, equilibrated lower jaw sensor<br />
is fixed to the front teeth using a paraocclusal<br />
attachment.<br />
Reference points can be entered using a probe tip.<br />
<strong>The</strong> receiver sensor equipment is integrated in the<br />
facebow.<br />
In addition to various possibilities for function<br />

when correcting the dynamic occlusion.<br />
For this, an automatic computation <strong>of</strong> the<br />
characteristic data <strong>of</strong> current, fully-adjustable<br />
articulators is carried out (SAM®, Panadent,<br />
PROTAR®, ARTEX®, Reference® and STRATOS®) .<br />

<strong>The</strong> control and evaluation is carried out using<br />
a commercially available PC.<br />
