Jaw Motion Analysis System
AREA OF USE AND SAFETY
INTENDED USE
Based on the lower jaw movements of the patient, the SICAT JMT
+
system calculates all the necessary
parameters with the goal of a supporting diagnosis for the following indications:
■ supporting diagnosis for treating a diseased mandibular joint
■ supporting diagnosis for creating occlusal mouth-guards
■ supporting diagnosis for creating dentures
■ supporting diagnosis for aesthetically functional reconstruction with or without tooth implants
■ supporting diagnosis for treating craniomandibular dysfunction (CMD)
The measurement system also enables the exporting of the gathered data for further processing with
CAD/CAM or PACS systems.
The measurement system may only be used by trained dentists. The area of use is limited to dental
systems. A measurement is carried out within 15 minutes and should not be applied in the case of open
wounds in the oral and head area; it can be applied to patients who are over 10 years old and who are
mentally capable of exactly following the instructions of the operator.
USE
The SICAT JMT
+
system is an electronic recording system that is based on 3D ultrasound measurements.
SICAT JMT
+
systems record the lower jaw movements of the patient in all degrees of freedom.
The 3D presentation of the positions and movement paths of occlusal or juxta-articular measurement
points provides important information on the movement behavior of the mandibular joint and the teeth
on the lower and/or upper jaw. The 3D presentation of distinctive positions in the face provides a
mapping of the facial symmetry for the fitting of the denture. In a functional, preliminary examination,
any discoordinations and limitations of movement can be analyzed and documented.
The electronic position analysis of the condyles enables different occlusion positions to be compared and
can thereby indicate possible pain vectors in the joint.
An analysis of the chewing movements takes place with a special software module. The XML export
function enables the use of jaw movements determined with the SICAT JMT
+
system in CAD/CAM systems
and PACS systems for the functional optimization of dentures and of mouth-guards.
The measurement system may only be used by trained personnel, meaning dentists in dental facilities.
The SICAT JMT
+
is used to support the functional diagnosis. The measurement sensor technology consists
of a receiving sensor and a transmitting sensor. This is attached to the patient's head. The lower jaw
sensor technology is fitted with a special locking mechanism for fixing it to the attachment. The face bow
is positioned at the front with the support on the nasion and at the back of the head above the ears. A
measurement can then be carried out according to the required settings and measurement parameters
in the software.
All the measurement and/or analysis results of the SICAT JMT
+
system should always be interpreted by a
trained specialist and checked for their relevance in consideration of the clinical medical history of the
patient and in the context of the further diagnostic procedure. If invasive measures are taken, the
measurement system should only be used as an additional assessment method. Under no circumstances
can or should invasive surgery or measures that put the patient at risk be carried out based on the
measurement results alone.
