Zebris JMA-Optic is a non-contact optical jaw-tracking system that captures true mandibular movement, eliminates the need for a mechanical facebow, and exports Real Movement and EPA data directly to virtual or mechanical articulators and CAD/CAM systems like Exocad — bringing precise, function-based occlusion into your digital workflow.
Zebris JMA-Optic Jaw Tracking & Dynamic Occlusion System
The new dimension of jaw registration for perfect function in dentistry. Non-contact, precise, and fully integrated into your digital workflow — from mandibular motion capture to CAD/CAM-ready articulator data.
The Zebris jaw registration system JMA-Optic quickly, non-invasively and precisely records all degrees of freedom of lower jaw movement. Functional analysis examinations can determine discoordination and movement limits, as well as establish a neuromuscular jaw relation — giving clinicians objective, reproducible data instead of relying on manual bite records alone.
To create functional dentures, the system calculates the setting values of common mechanical and virtual articulators and makes these available — together with the Real Movement data — as an export file for CAD/CAM systems. The result: a genuinely digital bridge between how a patient’s jaw actually moves and how that motion is translated into restorative design.
Key Advantages at a Glance
Movement Recording of Mandibular Function Captures the full range of jaw motion in real time, non-contact and optically tracked.
Functional & Digital Occlusion Analysis Moves beyond static bite records to analyze how occlusion behaves during actual function.
No Mechanical Facebow Required The patented Zebris coupling spoon determines upper jaw position directly — eliminating a manual step.
Articulator Setting Parameters Automatically calculates setup values for both mechanical and virtual articulators.
Neuromuscular Jaw Relation Supports determination of a physiologically relaxed mandibular position for complex cases.
Electronic Position Analysis of Condyles (EPA) Objective, quantifiable condylar position data to support TMJ and restorative diagnostics.
Direct CAD/CAM Interfaces Seamless data export to systems such as Exocad for a fully connected digital workflow.
Reproducible, Operator-Independent Data Optical tracking reduces the variability inherent in manual bite-registration techniques.
Advantages of Zebris JMA-Optic Jaw Tracking Dynamic Occlusion Registration System
The Interface to Digital Dentistry
The JMA system is prepared for the export of all individual movement data needed to create functional dental prostheses — forming a critical functional link in the digital workflow. The scannable, patented Zebris coupling spoon measures the position of the upper jaw and establishes the relationship between the tooth surfaces and the system’s mandibular sensor.
The motion data captured by the JMA system can be used directly as Real Movement data, or transmitted for programming virtual articulators into CAD/CAM systems such as Exocad. A mechanical facebow is no longer necessary at any stage of the process.
Optical Jaw Tracking→ Coupling Spoon Registration→ Real Movement / EPA Data→ Virtual or Mechanical Articulator Setup→ CAD/CAM Export (e.g. Exocad)
Why this matters clinically: Traditional facebow transfer and static bite records only describe where the teeth meet — not how the jaw actually moves to get there. By capturing real, patient-specific motion and condylar behaviour, the JMA system allows restorations, occlusal devices, and articulator setups to be designed around how the patient truly functions, rather than an averaged or estimated value.

Frequently Asked Questions
What is the Zebris JMA-Optic system used for?
It is a non-contact optical jaw-tracking system that records the full range of mandibular movement, determines upper jaw position without a mechanical facebow, and exports the resulting data to mechanical or virtual articulators and CAD/CAM systems such as Exocad.
Do I still need a mechanical facebow with this system?
No. The patented Zebris coupling spoon determines the position of the upper jaw directly, making a mechanical facebow unnecessary in the workflow.
Can the JMA-Optic system integrate with my existing CAD/CAM software?
Yes. The system exports Real Movement and Virtual Articulator data via XML for use in CAD/CAM platforms, including direct integration with Exocad.
What is the difference between the Basic Measurement Module and the optional modules?
The Basic Measurement Module (included) covers articulator setting-value calculation, upper jaw position, and core data export. Optional modules extend functionality into 3D motion analysis, CMDfact interaction, neuromuscular jaw relation, condylar position analysis (EPA), CEREC-specific articulation, and digital occlusion analysis — allowing the system to be scaled to your practice’s specific diagnostic and restorative needs.
Is the Zebris JMA-Optic suitable for TMJ/TMD assessment?
The system’s Electronic Position Analysis of Condyles (EPA) and neuromuscular jaw relation modules provide objective, quantifiable movement and positional data that can support TMD assessment as part of a comprehensive clinical work-up. It is a diagnostic measurement tool and should be used alongside, not instead of, a full clinical examination.
How is the WINJAW+ software operated?
WINJAW+ can be operated via a wireless foot switch or the computer keyboard, with real-time tracking of every recorded movement on screen. Recordings can be reviewed and repeated at any point during the session.
