optical measurement of mandibular kinematics
To improve the dental prostheses of their patients, more
and more practitioners make individualized prostheses by
measuring mandibular kinematics.
At the IDS 2019 I had the opportunity to examine
several devices which measure mandibular kinematics.
Out of all these, I have chosen to present to you the
new measurement system produced by the renowned
company Zebris Medical GmbH. While at the company zebris Medical GmbH
stand, Eng. Wolfgang Brunner, one of the owners of the
company, made a very detailed presentation of the Optic
Jaw Motion Analyzer.
aw Motion Analyser
This system extends Zebris'US JMA systems with state-of-
the-art optical sensor technology. The analyzer is made of
a handy table stand with an inductive charging station and
face bow with a lower jaw sensor.
The face bow is easily mounted by adjusting the nasion
support, sliding porion earpieces and spring-mounted
side arms. The jaw sensor is magnetically fixed onto the
paraocclusal or occlusal attachments to the lower teeth. The Optic Jaw Motion Analyser (Zebris Medical GmbH, D-88316 Isny,
