Tri Auto ZX2- Cordless Apex Locator and Canal Shaping Handpiece

J Morita’s revolutionary Tri Auto ZX2 is a compact, cordless motor with a built-in apex locator. It can be used for obtaining apical patency and creating a glide path using rotary instrumentation.  Rotary files as small as #10 may be used with the Tri Auto ZX2.  Responsive, the handpiece allows subtle and delicate manipulation of the file, corresponding to the movements of an experienced dentist’s hand.  Tri Auto ZX2 also offers a safe and efficient method for canal shaping.


Three functions in one powerful instrument:

- Achieves apical patency
- Shapes canals - compatible with all standard NiTi files
- Apex locator and measures canal length 

Apical Patency and Glide Path Using a Motor
OGP Function (Optimum Glide Path)

Using #20 or smaller files, the motor can be used to achieve apical patency and create a glide path.  It reproduces the subtle and delicate finger movements of an experienced dentist. Even curved or constricted canals can be treated faster and more safely. Both NiTi files sized #20 or smaller, or stainless steel files sized #15 or smaller may be used.

Safer and Efficient Canal Shaping
OTR Function ( Optimum Torque Release)

Depending on the load on the file, the motor alternates between forward and reverse rotation with great sensitivity to prevent jamming and file breakage.  It is also superior in its ability to follow the shape of even curved canals to reduce ledges and over instrumentation. Tri Auto ZX2 is compatible with standard NiTi files – no need to purchase specialty files.


File Tip Position Monitored in Real Time

File location and canal length are monitored in real time. Even if the working length is altered by shaping. The display accurately shows the file position with respect to the working length.

Automatic Stop Safety Function

The Tri Auto ZX2 motor is linked with the canal measurement function.  This feature makes endodontic treatment safer and more efficient. The position of the file tip inside the canal is shown in the display, and the motor stops or reverses rotation as soon as the file reaches the end of the working length to prevent over instrumentation. Also, the auto start and stop function automatically starts the motor when the file is inserted into the canal and stops it when it is removed.

OAS ( Optimum Apical Stop) Function

When the file reaches the end of the working length, it reverses slightly. This reduces the possibility of file jamming and separation.

Precise Manual Canal Measurement

Canals can be also measured manually. A file holder is provided. The ration of the impedances of two different frequencies is calculated so that the location of the apex is determined with great accuracy regardless of whether the canal is wet or dry. The file tip location is clearly shown in an easy to read meter display.  The combination of tactile feedback and the meter reading makes it east to determine the location of the file tip. A beeping sound also acts as a guide to its location.
