Aseptico ASC-12 Piezoelectric Scaler

Congratulations!

Your new Aseptico ASC-12 Amplitude™ Piezoelectric Scaler is preferred for ultrasonic scaling and endodontic treatment over older-style magnetostrictive scalers. This is because the ASC-12 uses a more precise linear scaling motion, whereas magnetostrictive types provide a wider, imprecise elliptical motion. The more direct linear motion also reduces the user's exposure to the bioburden carried in aerosols and allows the user to clean stains and calculus at lower power settings, which is less likely to damage tooth enamel.

Piezoelectric vs. Magnetostrictive Scaling

Piezoelectric:

• Linear motion
• Less vibration
• More precision

Magnetostrictive:

• Elliptical motion
• More vibration
• Less precision
• More exposure to aerosols

NOTE: New users of piezoelectric scalers may be inclined at first to set their ASC-12 Amplitude™ to similar power levels as those for magnetostrictive devices; however, this is not recommended because the scaling experience between these two technologies is totally different! It is recommended that you first try your ASC-12 at lower power levels and then adjust the power upward in order to find your ideal setting.

Safety Precautions

Aseptico accepts no liability for direct or consequential injury or damage resulting from improper use, arising in particular through the non-observance of the operating instructions, or improper preparation and maintenance.

WARNING: Clean, disinfect, and sterilize new or repaired handpieces and instruments before first use and between each patient use. Only use sterilized handpieces and instruments during treatment. Non-sterile handpieces and instruments may cause bacterial or viral infections. Always sterilize handpieces and instruments after operation.

CAUTION: Always examine unit components for damage before commencing treatment. Damaged components must not be used and must be replaced.

WARNING: Use for intended purposes only. Failure to observe the operating instructions may result in the patient or user suffering serious injury or the product being damaged, possibly beyond repair. Before using this product, make sure that you have studied and understood the operating instructions.

WARNING: For use by qualified and trained personnel only.

WARNING: Always apply tip against tooth surfaces when scaling. Avoid unnecessary contact of tip with soft tissues, such as gingival, mucosa, or skin. Incidental contact with tissue can cause tissue burn or damage.

WARNING: Do not install where there is a risk of an explosion. The ASC-12 Scaler is not intended for operation in the presence of flammable anesthetics or gases.

WARNING: CONTRAINDICATIONS: The ASC-12 Scaler MUST NOT be used when the patient and/or operator has a cardiac pacemaker. Ultrasonic oscillations emitted by the scaler may prevent the proper function of the pacemaker.

WARNING: Instrument tips may fracture. The scaler tips oscillate at high frequency during operation. In rare cases, these oscillations may cause the tip to fracture during treatment. To prevent the patient swallowing or inhaling the fractured tip, he or she must be instructed to breathe through the nose during treatment.

CAUTION: Check for abnormal vibration of tip before using. If abnormalities are found, stop using Scaler immediately and contact Aseptico.

CAUTION: Do not allow tip to touch ceramic prosthesis during scaling. This might damage the tip.

WARNING: Do not use the ASC-12 Scaler dry. If used dry, the instrument tip will heat immediately. This may cause thermal injury to the tooth. Ensure that adequate liquid coolant is always available. Irrigate abundantly and continuously.

NOTE - Exceptions for using the ASC-12 Scaler without water coolant: Although in almost all cases ultrasonic scalers will be used with water, piezoelectric scalers are also used without water to thermo-soften gutta percha.

CAUTION: Never use the ASC-12 Scaler on metal or porcelain restorations. The high frequency ultrasonic oscillations may loosen the restoration.

WARNING: Do not disassemble or alter the Scaler handpiece.

WARNING: Do not drop handpiece or impact it against hard surface. Damage to handpiece could result in electric shock.

CAUTION: Do not drop Scaler console or impact it against hard surface. Damage to console could result in electric shock.

DANGER: NEVER REMOVE THE CONSOLE HOUSING FROM THE CONTROL ELECTRONICS. DANGEROUS VOLTAGES ARE PRESENT WHEN UNIT IS OPERATING AND CAN CAUSE FATAL INJURY IF ELECTRONICS ARE EXPOSED AND HANDLED IMPROPERLY.

Maintenance & Sterilization

1. Control Console:

CAUTION: DO NOT IMMERSE the device in any fluid. The exterior of the console may be wiped clean with a soft cloth moistened with mild detergent or disinfecting solution.

The system allows for a disposable sanitary plastic barrier to be placed over the control console and handpiece. Replace disposable plastic barrier between each patient use.

2. Handpiece:

a) Handpiece Cleaning:

Thorough cleaning of the scaler handpiece after each use and before sterilization is very important to ensure proper operation and service life of the handpiece. Wipe off the handpiece, handpiece terminal, and cable with a soft cloth moistened with mild detergent solution or 45% isopropyl disinfecting solution. CAUTION: DO NOT IMMERSE the handpiece in any fluid, or spray any fluid directly on the handpiece. Before reinstalling the handpiece, check the water circuit O-ring for damage or wear and replace if necessary. NOTE: When wiping down the handpiece cable, gently wipe from the middle of the cable out to the handpiece and console. Avoid gripping the cable tightly.

IMPORTANT:

• Turn power Off before disconnecting handpiece. Never disconnect handpiece while the instrument is powered and/or the control pedal is activated.
• Always check for any handpiece damage during operation and when sterilizing.
• After each use, flush out the handpiece water circuit and tip with water for approximately 30 seconds.

b) Water Circuit O-Ring Replacement:

The handpiece water circuit O-ring should be replaced if damaged or worn. Use the O-ring installer pin and sleeve provided to replace O-ring:

• Remove old O-ring from handpiece water circuit connector.
• Slide new O-ring over pointed end of installer pin, onto the pin's shank (see Figure 5a).
• Insert pointed end of installer pin into open end of installer sleeve until O-ring stops against end of tool.
• Position concave end of installer pin against end of water circuit connector on handpiece (Figure 5b).
• Push installer sleeve inward, until new O-ring seats into groove on water circuit connector (Figure 5C).

Figure 5a, 5b, 5c - Replacing O-Ring: These figures illustrate the process of replacing the water circuit O-ring on the handpiece. They show the installer pin, installer sleeve, O-ring, and the water circuit connector on the handpiece. The steps involve removing the old O-ring, placing the new O-ring onto the installer pin, inserting the pin into the sleeve, and then using the sleeve to seat the new O-ring into the connector groove.

NOTE: To help prolong the life of the water circuit O-ring, lubricate the O-ring with a light coat of silicone grease or pure petroleum jelly after each disassembly or sterilization.

c) Handpiece Sterilization:

Sterilize handpiece between each patient use. Steam autoclave for 20 minutes at 132°C (270°F).

Sterilization Procedure:

• Separate the handpiece from its terminal.
• Use compressed air to remove any irrigation fluid in the handpiece. Shake the water out of the terminal and hose.
• The handpiece must always be sterilized without the tip installed.
• Put the handpiece in a sterilizable bag or cloth.
• Remove the handpiece from autoclave once sterilization is complete.
• Thoroughly dry the electrical contacts of the handpiece before using.
• Always check handpiece for damage after sterilization.

IMPORTANT: Never sterilize the handpiece with the tip installed.

3. TIPS:

a) Tip Installation:

The scaler handpiece can accept ultrasonic piezo tips with a 3m x 0.6 metric mounting thread size. The tips must be screwed on and tightened with the wrench provided.

CAUTION: Avoid overtightening when installing tip. Overtorquing the tip beyond the thrust point may cause the tip to jam and affect performance. It is recommended that the tip be removed after each procedure to prevent jamming.

b) Tip wear:

The shape of the tips should be checked regularly to maintain optimum performance. Never alter the shape of a tip by bending or filing. Check the wear of the tips against the tip card provided by the tip manufacturer. Damaged or worn tips must be replaced.

c) Tip Sterilization:

The scaler tips should be sterilized between each patient use. Refer to the tip manufacturer's instructions for cleaning and sterilizing procedures.

Clinical Applications

1. Scaling with the ASC-12 System:

• Press power switch to On ( I ) position. Each of the LED indicators on the console should flash once consecutively before reverting to the last used setting.
• Activate the foot control pedal.
• Adjust the spray flow (See Fig. 6).

Figure 6 - Spray Flow Adjustment

This diagram shows the spray flow adjustment knob located on the rear view of the console.

• Operate the scaling instrument.

CAUTION: Do not press foot control pedal while switching the unit on/off.

NOTE: The scaler vibrates the tips from front to rear, along the tip axis. This straight, single-plane motion allows better, more accurate access to the tooth and gingiva. The user should consider the particular shape and vibration characteristics of each tip to achieve optimal performance.

IMPORTANT: Consult the tip manufacturer's instructions for use before performing any general scaling, periodontic, or endodontic treatments.

WARNING: Ensure proper spray flow before using Scaler on a patient. Heat emitted by the Scaler may damage teeth if water is not atomized at the Scaler tip. Irrigate abundantly and continuously.
