The Tri Auto mini is a compact, cordless endodontic handpiece designed to assist with mechanical root canal preparation while offering the feel and control close to manual filing. Its ultra-small and lightweight head improves access and visibility in posterior teeth, and automatic functions such as auto torque reverse help reduce file jamming and breakage during instrumentation. The handpiece features an easy-to-read LCD display with color-coded feedback and can be paired with a compatible apex locator (like the Root ZX mini) to monitor file tip position in real time and enhance procedural safety and efficiency.
