Precise recording of the state and mobility of the mandible joint is
indispensable for optimum prosthetic treatment and functional analysis.
With the aid of zebris JMA measurement systems - based on the travel
time of ultrasound impulses - simple, rapid and high precision measurements
are possible with extremely light sensors.
A sensor pen which is included in the scope of supply allows the input
of the profile as well as points on the occlusal area.
This newly developed system determines the optimum kinematic axis from
protrusion and opening movements. Misinterpretations of the functional
evaluation of the condyle paths will be minimized through this.
Measurement can be monitored in real time. The parameters of functional
analysis, in addition to the settings of the fully adjustable articulators
are issued in an automatically produced report.
The measurement systems can be extended to various applications, ranging
from the recording of myographic data to analysis of functional disturbances
of the cervical spine.
The basic system zebris JMA20 fulfills all requirements of the modern
functional jaw movement analysis.
