Motor’s Safety Features Simplify Procedures and Protect Patients

J. Morita USA’s Tri Auto ZX2 is a compact, cordless motor with a built-in apex locator. Redesigned with breakthrough canal treatment technology, this unit simplifies procedures while protecting the patient with innovative safety features, the company reports.

The Tri Auto ZX2 may be used for achieving apical patency and creating a glide path with the Optimum Glide Path function. According to J. Morita, the responsive handpiece allows subtle and delicate manipulation of the file, facilitating faster and safer treatment in even the most difficult cases involving constricted or extremely curved canals. Rotary files sized as small as a #10 may be used.

In addition, this unit offers Optimum Torque Release (OTR) technology, currently available on the Root ZX II apex locator handpiece. During file rotation, the torque is automatically measured. If the torque exceeds a preset value, the file reverses rotation incrementally until the torsion is released and then resumes in the cutting direction. OTR is designed to offer superior navigation of canals, improve efficiency, and reduce the possibility of file jamming, breakage, ledge formation in curved canals, and canal transportation.
