Features Features and intended use: The Tri Auto mini is a compact, cordless endodontic treatment motorized handpiece for preparation and enlargement of root canals. It may be connected to the Root ZX mini, an apex locator (sold separately). Instructions for how to use the Tri Auto mini when it is connected to the Root ZX mini are printed on a blue background like this one.

Liquid Crystal Display (LCD) : The LCD is easy to read and shows all settings as well as how the motor is running.

Controls : Speed :

Eleven rotation speeds can be set from 50 to 1,000 rpm.

Torque Reverse :

The motor automatically reverses its rotation if the torque load exceeds the set value to reduce the risk of jamming.

Slow Down :

The file slows down as torque increases. The file slows down as it approaches the apex if the Tri Auto mini is connected to the Root ZX mini.

Forward & Reverse :

The file may rotate in both forward and reverse directions.

Auto Start & Stop* :

The file starts when it is inserted in the canal and stops when it is taken out.

Apical Reverse or Stop* :

The motor reverses or stops when the tip of the file reaches a preset position inside the canal.

Apical Torque Reduction* : The automatic torque reverse value is reduced as the file tip approaches the apex. * These controls can be used if the Tri Auto mini is connected to the Root ZX mini.

(1) Before Use Charge Battery

The battery is built into the motor handpiece.

* Ambient (room) temperature for charging is from 10ºC (50ºF) to 40ºC (104ºF). 1

Green LED Connect the power cord to the charger and then plug it in. Turn the charger on. The green Power LED will light up. Do not use any charger; use only the one that comes with the Tri Auto mini.

Green LED

Orange LED

Put the handpiece into the charger as far as it will go. The orange Charge LED will light up to show that charging has begun. * Charging time is about 120 minutes.

Chage the battery as soon as the battery power indicator gets down to its last bar. If the orange charge LED goes off immediately or doesn’t light up when the handpiece is put into the charger, the battery is probably fully charged. To make sure, take the handpiece out and put it back in again. Make sure the contact areas for the handpiece and charger are free of debris, especially metal fragments. Wipe with ethanol to remove any foreign debris. Do not press down too hard to wipe the charging areas; this could bend the electrical contacts. Do not leave the charger where it will be exposed to direct sunlight.

•• If an electrical storm occurs while the battery is being charged, do not touch the charger or its cord as there would be a risk receiving an electric shock. •• Do not get the charger wet or use it where it might get wet.

•• The battery is not charged when the unit is shipped from the factory and must be charged before using the unit. •• Do not pull or yank the cord when disconnecting the AC adapter. Always grip the connectors. •• Use only the power cord provided and plug both ends all the way in. •• Charger and power supply cord must be located outside the so called patient environment (2.0 m around the patient location).

Operation 2010-12-16

Charge Battery The number of bars shows how much battery power is left. Recharge the battery when there is only one bar left.

If the battery runs almost completely out, the Tri Auto mini will automatically turn itself off after about 10 seconds. Recharge the battery as soon as possible.

If the battery power is very low and a large load is applied to the file, the motor may stop or the unit may turn itself off. This is for safety; there may not be enough power to run the motor with sufficient stability. Recharge the battery if the display shown to the left appears frequently. U sa g e

Connect Contra Angle

Line up the marks.

Approx. 290° The rotation range of the contra angle is about 290°. Set it so that it reaches the treatment area and the display is easy to see. Contra Angle

Motor Handpiece

Do not force the contra angle to rotate beyond its limit.

Line up the match marks and push the contra angle onto the handpiece until there is an audible click. * The contra angle must be lubricated with AR Spray before using for the first time. Refer to “Autoclaving the Contra Angle”.

•• Make sure the connection components for both the handpiece and the contra angle are not damaged. An improper connection could cause the motor to reverse unexpectedly and result in injuring the patient.

•• Push the contra angle all the way onto the handpiece and then give it a light tug to make sure it is securely attached. Operation 2010-12-16

File Installation File release button

Hold down the file release button Insert the file and turn it back and forth until it lines up with the latch mechanism. Push the file all the way into the latch. Release the file release button. Use either Nickel-titanium or stainless steel files.

For use with the Root ZX mini, connect the file electrode and the transmission cable .

•• Never use deformed or damaged files. •• Give the file a light tug to confirm it is securely held in place. If the file is not securely placed, it could come out and injure the patient.

•• Use caution when inserting and removing files to avoid injury to fingers. •• Inserting and removing files without holding the file release button down will damage the chuck. •• Make sure the Tri Auto mini is turned off before inserting or removing files. •• Do not connect the file electrode if the handpiece is not connected to the Root ZX mini.

Operation 2010-12-16

Check Operation File release button If a malfunction occurs, the Tri Auto mini will stop working. In this case, contact your local dealer or the J. Morita Corp. The number that appears after Error will depend on the type of malfunction. Main Switch

Plus and Minus Switches

■■ Make sure the contra angle and handpiece are properly and securely connected. ■■ Make sure the file is securely installed; give it a light tug. ■■ Check switch operation. U sa g e

Turn the Main switch on and use the Plus or Minus switches to select a memory. Then press the main switch again to see if the Tri Auto mini runs smoothly. Refer to page 18 for instructions on checking the Tri Auto mini’s operation when it is connected to the Root ZX mini.

•• Operate the Tri Auto mini outside the oral cavity to make sure it will operate properly before using it for treatment. •• Some canals may be impossible to enlarge; always take an x ray to check. •• Nickel-titanium file may suddenly snap depending on the curvature and shape of the canal; stop using the file if you notice or feel anything amiss. •• Files will eventually break due to metal fatigue and should be replaced before they reach this point. •• Electric noise or a malfunction could interfere with the motor control. Do not depend entirely on the unit controlling itself; always watch the display and be aware of tactile feedback. •• Files will jam and break if too much force is applied to them. •• Files may break even when the torque reverse is turned on, depending on the setting value. Never exert excessive force on the file. •• Files designed for use with engines break easily if too much force is applied. Also do not use these files for canals with excessive curvature. •• Always examine files for stretching and other deformities or damage before using them. Any type of deformity could result in the file breaking. •• Do not let the file release button on the contra angle press against the teeth opposite to the treatment area; this could cause the file to come out and result in an injury. •• Do not press the file release button while the motor is running. It could heat up and cause a burn, or the file could come out and cause an injury.

•• Stop using the Tri Auto mini if you feel or notice anything unusual. The Tri Auto mini cannot be used for every canal and should be used along with manual enlargement. •• File break more easily at fast speeds; always follow the file manufacturer’s usage recommendations. Also always check the speed settings before use. •• Do not use any type of files except nickel-titanium and stainless steel ones. •• Nickel-Titanium files are easily broken; note the following points. •• Open the canal up to the apical constriction manually before using a nickel-titanium file. •• Never use excessive force to insert the file. •• First remove all foreign matter, such as bits of cotton from the root canal. •• Never use excessive force to advance the file down the root canal. •• Do not use for extremely curved canals. •• Try not to trigger the auto torque reverse function when advancing the file down the canal. •• Do not skip file sizes; suddenly using a much larger file could break it. •• If you encounter resistance or the auto torque reverse is triggered, back the file up 3 or 4 mm and carefully advance it down the root canal again. Or replace the file with a smaller size. Never use excessive force. •• Do not force the file down the root canal or press it against the root canal wall. •• Do not use the same file continuously in one position as this may create “steps” on the root canal wall. •• Always take file out of the contra angle after use.

Turn on the Tri Auto mini and Root ZX mini. The backlight for the display will be yellow. Hook the Contrary Electrode in the corner of the patient’s mouth.

Contrary Electrode

•• In some cases such as a blocked root canal, a measurement can not be made. (For details refer to the section of the Root ZX mini manual that covers canals not suitable for measurement.) •• Accurate measurement is not always possible, especially in cases of abnormal or unusual root canal morphology; always take an x-ray to check the measurement results. •• If the meter does not move when the file is inserted, the unit may be malfunctioning and must not be used. •• Do not use an ultra sonic scaler while the contrary electrode is hooked in the patient’s mouth; noise from the scaler could cause the motor to start running resulting in an accident or injury. •• Absolutely never allow the contrary electrode, the handpiece file electrode or the connections for these to contact an ordinary AC power source such as a socket; this could result in a very serious and angerous shock.

•• Occasionally the meter will make a sudden and large movement as soon as the file is inserted into the root canal, but it will return to normal as the file is advanced down towards the apex. •• The contrary electrode, file electrode and metal parts of the contra angle could cause an adverse reaction if the patient has an allergy to metals. Ask the patient about this before using the Tri Auto mini. •• Take care that medicinal solutions such as formalin cresol (FC) or sodium hypochlorite do not get on the contrary electrode or the contra angle. These could cause an adverse reaction such as inflammation. •• The file electrode cannot be used with the following types of files including nickel-titanium ones. Use these files without attaching the file electrode. Files with a shank diameter greater than 1.2 mm, Files with shanks that do not have a circular cross section, Gates Glidden Drills, Tools with large cutting heads such as largo burrs.
