Overview

Congratulations on your purchase of the Obtura III MAX! Please read the entire manual prior to 
using this unit. Here are some useful tips that will aid your usage of the Obtura III MAX:

When you are ready to practice with your Obtura III MAX, you should become familiar with its components. 
After attaching the needle and thermal protector, turn the Obtura III MAX on and set it to operating temperature. 
It takes the unit approximately 120 seconds to reach the highest operating temperature of 200°C. The high 
temperature setting will improve gutta percha flow, especially when used in the cold practice block (sold 
separately). Begin by filling the plastic practice blocks with gutta percha per the instructions included. Use 
condensers to condense the material void free. We recommend the Obtura Spartan S-Kondenser (available in 3 sizes).

 

 

The soft silver applicator needles are designed to conduct heat to insure 

 even at the needle tip; however,

as the needle tip cools between uses, you should express 3 cm of gutta percha to pre-heat the tip just prior to
use. The needles are bendable to fit the tooth, however, they may break if they are repeatedly bent or if they are
bent at the needle attachment point. Always use the Multi-Tool to bend the needle. Do not kink the needle, as
any restriction will impede flow. After a few practice sessions, proper needle bending will be easily accomplished.
Obtura applicator needles are designed for one use only.

 

 

Do not loosen or remove the blue plastic Heater Nut. The Heater Nut is fastened to the gun with a set-screw; 

removal of the heater nut will cause damage. The Heater Nut must be kept tightly fastened in order to secure the
heater to the handpiece when expressing gutta percha.

 

 

The stand for the handpiece may be positioned by itself or it may be attached to the bottom of the control

unit. The stand can be attached to either side of the control unit with four phillips-head screws that are fastened
to the bottom of the stand (see page 3 for further details).

 

 

The cord to the handpiece can extend from the front or rear of the unit. If a front exit is desired, gently press the

handpiece cable into the tracks on the bottom of the unit, to exit either on the left-front or the right-front (page 3).

 

 

Cleaning the Obtura III MAX is simple but very important; just follow the directions in this manual (page 6)

or on the provided laminated cleaning instruction card. If your Obtura III MAX is cleaned on a regular basis it
will provide years of reliable service. If you do not clean your unit, it may become clogged and difficult to move
the plunger due to a buildup of old, hardened gutta percha.

Overview

Congratulations on your purchase of the Obtura III MAX! Please read the entire manual prior to using this 
unit. Here are some useful tips that will aid your usage of the Obtura III MAX:

Thank you for purchasing the Obtura III MAX. We believe it is a beneficial instrument that will enhance 
your practice. We are continually striving to improve our products and services. If you have any questions or

System Description

The Obtura III MAX is intended for use by professionally-qualified dentists, endodontists and dental clinicians to heat 
gutta percha and to place it into the previously prepared root canals of human teeth, in order to provide quick and 
complete obturation of the root canal. 

There is a minimum level of understanding and background assumed in the descriptions and instructions found 
in this manual; if at any time you feel overwhelmed or unsure of how to properly operate your Obtura III MAX 
unit, immediately cease use and call Obtura Spartan for assistance. We value safety first and foremost.

The Obtura III MAX utilizes push-button digital temperature controls for more accurate, reproducible settings, 
and a memory function that stores up to 5 user-selectable temperature settings for your convenience. 

The Obtura III MAX complies with current Electromagnetic Compatibility standards (IEC 60601-1-2). The user should 
ensure that any possible electromagnetic interference is not present, as it could potentially damage the device or any 
other electronic device in the vicinity.

Unpacking and Assembling 

Check all packaging for signs of damage; report any damage with the shipping agent immediately, so that claims 
will be honored in a timely way.

Save all packing materials in the event of an instrument move or shipping at a later date (also see our “Greener 
Earth” commitment on the reverse side of customer introductory letter).

Remove the clear plastic introduction bag, main control unit, handpiece, handpiece stand (complete with stand 
attachment spacer and screws), power supply box, bagged supplies and accessory tool kit. Check for loose items.

Unwrap the main control unit and place on a flat surface. Locate the unit so that by extending the cord you will 
not pull the unit off the surface. The handpiece cable length is approximately 224 cm (88 in.). 

Locate the handpiece stand and place it next to the main control unit. The stand provided for the handpiece can 
be attached to the Obtura III MAX (if desired) by the following means:

          After determining which side you want the stand placed on, simply remove the 2 screws on the bottom of   

--------

the stand. After the screws are removed, hold the attachment plate to the bottom of the stand, and re-attach 

--------

it to the desired location so it hangs off the side (as shown in diagram A). Then attach the handpiece stand 

--------

and bracket to the main control unit using the two remaining screws (see diagram B).

Plug the handpiece cord connector into the rear of the main control unit (note the alignment of the “red dot” at the 
12 o’clock position, and a “click” to signify complete insertion). Should the user require the cord to exit the front 
of the unit, invert the Obtura III MAX on a smooth, soft surface and gently press the cable into the tracks provided, 
leaving a small loop of cable from the handpiece cord port to the beginning of the track. The cable can exit on the 
left-front or the right-front (see diagram C), or from the rear (without use of the cable tracks).

Open the white power supply box and remove the power supply unit and receptacle blades. Choose the correct 
blade to fit your electrical outlet and slide it on to the power supply unit. Plug the power supply connector into 
the power supply port at the rear of the main control unit; plug the power supply unit into an electrical outlet. The 
Obtura III MAX screen will momentarily light up, indicating the version of installed firmware, and then turn off. 
This only occurs when first connecting the main control unit to the electrical outlet.

Installing a Needle

To place the gutta percha where desired in the root canal, choose an applicator needle diameter best suited (20, 23 or 
25-gauge). With the Obtura III MAX off and cool, remove the needle nut using the Multi-Tool; the needle nut should 
remain on the Multi-Tool when unscrewed. Place the appropriate needle in the rear of the needle nut, so that the length of 
the needle protrudes through and forward (diagram G). Re-attach the needle nut on to the heater thread using the Multi-
Tool, making sure not to cross-thread (diagram H). Tighten until snug (do not over tighten, but do not leave too loose).

Bending the Needle

In most situations, a straight applicator needle will not provide access to the root canal. Using the Multi-Tool, gently 
bend the needle to provide a shape conducive to the procedure (see diagram I). Be careful not to bend too sharply as 
kinks will result and gutta percha flow will be blocked. For access to difficult to reach root canals, simply loosen the 
needle nut, rotate the needle to desired position, and then re-tighten.

Loading Gutta Percha

WARNING: USING MORE THAN ONE STICK OF GUTTA PERCHA AT A TIME MAY DAMAGE THE SEAL. 
DO NOT USE MORE THAN ONE PIECE AT A TIME.

Power on the Obtura III MAX and wait for the heater to come up to your desired temperature. Press the handpiece release 
button on the top of the Obtura III MAX handpiece and withdraw the plunger shaft. Insert a gutta percha stick into the 
chamber via the opening just forward of the release button (see diagram J). Re-insert the plunger shaft until the plunger seal 
engages the gutta percha pellet. Some resistance will be felt as the gutta percha is pushed forward to the heating chamber. 

Expressing Gutta Percha 

Specifics to technique will not be addressed here, but a few reminders and hints follow:

         

 When expressing gutta percha, do not “

withdraw

” the Obtura III MAX, but let the gutta percha fill “

push

” the

----------

needle out of the canal. Pulling the needle out may cause voids and require condensation or re-work. 

         

 Take care when bending needles, as a kink will make it all but impossible to express material. Also, repeated

----------

bending will cause needle weakening and subsequent breakage. 

         

 Wait for the gutta percha to come up to full operating temperature before attempting to express; material that

----------

is too cool will require much more pressure or may be impossible to pass through a small diameter applicator needle. 

         

 Before beginning a procedure, express about 3 cm of gutta percha so that the up-to-temperature material will be

----------

at the end of the needle; the warm material will fill space more completely.

STERILIZATION INSTRUCTIONS

Sterilization Instructions

The Obtura Thermal Protectors are designed to provide patient protection from the elevated temperatures 
of the heating chamber. Patient contact requires that the Thermal Protectors be sterilized between uses to 
prevent cross-contamination issues.

Thermal Protector Sterilization Instructions

1.

Turn off the unit and allow it to cool to room temperature.

2.

Using the Obtura Multi-Tool, disengage the tab on the rear of the thermal protector.

3.

Pull the Thermal Protector off the front of the handpiece.

4.

Place the Thermal Protector in a cassette-style autoclave at 135°C for 10 minutes.

NOTE: The Applicator Needle on the Obtura is not intended for multiple uses. It should be removed after 
a single use and disposed of. A new Applicator Needle shall be used for each procedure. Failure to change 
the Applicator Needle increases the risk of cross-contamination during a procedure.

5. After replacing the Applicator Needle, Reinstall the Thermal Protector by pressing it onto the front of
the handpiece. Be careful of the Applicator Needle as it is capable of injuring your hand.

By steam sterilizing the Thermal Protector and using a new Applicator Needle every time, you are greatly 
reducing the chance of any cross-contamination to your patients.

 GUTTA PERCHA 

SYSTEM

In the control unit, the data stream from the handpiece is read (and the temperature interpreted) by a micro controller. 
This builds display data for the LCD and reads the touch-panel. The processor also turns the heating element on and off 
several hundred times per second to maintain constant temperature. A “watchdog” processor performs self-diagnostics 
for the system.

Power supply voltage never enters the Obtura III MAX, as the voltage is converted to 12-volts DC via an external switch-
mode power supply. Selection and installation of the appropriate plug blade is all that is necessary to configure the unit. 
Low-voltage enters the control unit case via a “standard” power supply connector.

Frequently Asked Questions

Q. How often should the unit be cleaned?
A. The Obtura III MAX should be cleaned at the end of each day or procedural session (see page 6).

Q. How often should the applicator needle be changed?
A. The applicator needle must be changed after each patient operation and when damage is detected or suspected. This is

----

to ensure proper operation and to prevent the spread of infectious diseases.

Q. How often should the plunger seal be changed?
A. Observe seal for wear; replace if seal is torn or missing (see page 8).

Q. Why should I only use one pellet of gutta percha?
A. Critical lengths of the mechanical components of the Obtura III MAX have been designed for a single piece of gutta

----

percha; using more can cause excessive back pressure and damage (see page 5).

Q. Is the Obtura III MAX Handpiece Autoclavable?
A. No, the Obtura III MAX handpiece is not autoclavable. It should be cleaned using a BIREX-type solution. Only the

 GUTTA PERCHA 

SYSTEM

Theory of Operation 

The heating system of the Obtura III MAX is a closed-loop design to ensure consistent temperatures and uniform gutta 
percha flow. This means that the temperature of the heater is read several hundred times per second and corrected (as 
necessary) to insure accurate and consistent heating. 

In the handpiece, the temperature of the heating chamber is detected by a thermocouple integrated into the heating 
element and encapsulated with epoxy. The output from the thermocouple is converted by an analogue-to-digital 
converter, and into a digital stream for use by the main control unit.

The handpiece is composed of a two-piece heat-resistant composite body that encapsulates the trigger assembly, heater 
system and plunger.

Gutta percha is placed into the top of the handpiece shell and expressed via the plunger shaft assembly. Pressing the 
handpiece trigger, which pushes the shaft via a spring-loaded pawl, moves the shaft forward. The heater assembly is 
directly connected to the handpiece shell, providing a straight through path for gutta percha, warming it in the process.

ERROR CODES 

Maintenance

For best results, the Obtura III MAX handpiece should be cleaned daily. This prevents build-up of excess gutta percha 
within the heating chamber.

7. Push and hold the release button, removing the plunger shaft from the handpiece. Visually inspect the plunger seal

---

to determine if a replacement is necessary (example: metal threads at the tip of the plunger shaft are exposed or there

---

is other obvious erosion).

8. Using the heater reamer tool, clean the handpiece shaft in a back and forth motion until all visible gutta

---

percha is cleared.

9. Dip the cleaning brush into the cleaning solution, fully coating the brush. Clean the handpiece shaft with the cleaning

---

brush in a back and forth motion until all excess gutta percha is cleared.

10. Reassemble all components in the reverse order from which they were detached. Place the handpiece back

-----

on its cradle.

WARNING: AT NO POINT SHOULD ANY PART OF THE OBTURA III MAX HANDPIECE BE SUBMERGED 
INTO THE CLEANING SOLUTION.

NOTE:

 A) For optimal cleaning, use a Birex®-type solution to aid in disinfecting and deodorizing your Obtura III MAX unit.

B) Never spray the disinfectant solution directly on to the unit; always spray into a disposable cloth, then wipe down.

*The heater reamer tool should only be used as needed.

The Thermal Protectors must sterilized before use.

Handpiece Bushing

Handpiece Bushing is susceptible to wear caused by the bushing misalignment. This causes the trigger pawl to wear 
at the pawl engagement opening. The bushing should be aligned in the handpiece so that bushing rotation ceases. To 
install the handpiece bushing, slide it in the opening at the rear of the handpiece (diagram K), and turn clockwise until 
resistance is felt. The handpiece bushing should be cleaned or replaced as needed.

Plunger Shaft Assembly

Areas of inspection consist of the plunger seal and the plunger teeth. The plunger seal should be inspected for wear or 
breakage. Gutta percha expressed through the handpiece will give a quick and accurate indication of the plunger seal’s 
condition. If excessive gutta percha passes by the seal, the plunger seal assembly should be replaced. The plunger teeth 
should be inspected for wear or chipping. The plunger shaft should be replaced if plunger teeth are badly chipped or 
slipping occurs during testing. The plunger shaft of the Obtura III MAX should be checked for bending; if it will not roll 
smoothly on a piece of glass or flat tabletop (indicating a bow or bend), it should be replaced, as the use of a bent shaft 
may cause damage to the heater bore.

Plunger Seal Assembly

To remove the plunger seal assembly, first locate the Multi-Tool’s small hex shape opening (diagram L). Then heat the end of the 
plunger shaft (a lighter will work; please use precaution) to soften the thread-locker. After the thread-locker softens, carefully 
insert the plunger seal assembly within the hex shape opening, and unscrew the plunger seal assembly from the plunger shaft 
(diagram M). To replace the assembly, thoroughly clean the end of the plunger, using extra care, to be sure the threads are clean 
and dry. Re-apply and tighten the plunger seal assembly using the Multi-Tool’s hex utility once again. Do not over-tighten. 

Needle Nut

The needle nut may become filled with gutta percha, which will inhibit complete tightening and thermal transfer from 
the heater to the applicator needle. The needle nut threads can be cleaned with a 1/4-28 tap, but it’s usually more 
efficient to replace it. The needle nuts can be collected and cleaned thoroughly at a later date for re-use. If the needle 
nut does become filled with gutta percha, it may indicate that the needle nut has been tightened insufficiently. Use the 
Multi-Tool to assure proper fit.

Handpiece Cable Assembly 

The handpiece cable should be thoroughly inspected at the handpiece entry point for broken wires and cracks in the cable 
housing (may be due to the frequent bending in this area). These signs are an intermittent problem where the unit will 
work fine initially, but when the handpiece cable is bent, the unit stops heating altogether. If these conditions exist, the 
error codes on the Obtura III MAX display can diagnose them (see error codes chart on page 9).
