Master Your Endodontic Workflow with Unmatched Precision and Freedom
Navigate the complexities of root canal therapy with a tool designed for absolute control and intuitive performance. The Tri Auto mini isn’t just a motor; it’s a complete system that anticipates your needs, protects your instruments, and enhances your clinical outcomes. By eliminating cords and integrating intelligent safety features, it allows you to focus entirely on the art of canal shaping.
Key Features for Advanced Canal Preparation
True Cordless Freedom & Superior Ergonomics
Forget the limitations of cords. The Tri Auto mini‘s lightweight, perfectly balanced pen-style design offers complete freedom of movement and significantly reduces hand fatigue during long or complex procedures. Its compact contra-angle head provides excellent visibility, even in difficult-to-access posterior regions, ensuring you never miss a detail.
Intelligent Safety with Auto-Reverse Functions
Protect your investment in files and ensure patient safety with Morita’s proven auto-reverse technology. These features work together to dramatically prevent file separation and procedural errors.
- Auto Torque Reverse: The motor instantly reverses rotation the moment the torque load exceeds your preset limit, effectively reducing instrument fracture.
- Auto Apical Reverse: When connected to the Root ZX mini, the motor automatically stops and reverses as the file tip reaches the apex, minimizing the risk of apical perforation.
Seamless Apex Locator Integration for Ultimate Confidence
Transform your workflow by connecting the Tri Auto mini to the Morita Root ZX mini apex locator. This powerful synergy allows you to perform canal shaping and length determination simultaneously. You can monitor the file’s exact position in real-time on the apex locator’s screen, providing a clear visual guide that allows for safer and more accurate root canal instrumentation.
Intuitive Control and Programmable Memory
The clear LCD display provides at-a-glance information on speed, torque, and battery life. With 6 programmable memory settings, you can instantly recall your preferred parameters for different file systems, saving valuable time and ensuring consistent, reproducible results for every treatment.
