AZDENT Dental Polisher Kit

1. Product Overview

The AZDENT Dental Polisher Kit is designed for polishing dental restoration materials such as zirconia, ceramics, composite resin, non-precious metal alloys, and precious metal alloys/silver amalgam. It is also used to remove adhesive residue from dental enamel, to smooth dental enamel, and to remove plaque within the oral cavity. This kit includes 12 pieces, comprising 6 polishing brushes and 6 silicone polishers, provided in a convenient box.

The product is reusable and requires thorough cleaning, disinfection, and sterilization before each use. The end of life for the product is determined by wear and damage, such as corrosion, surface flaws, deformation, dirt, and exposure of the shank.

4. Setup and Installation

The polishers and brushes are designed for use with a low-speed handpiece. Ensure the handpiece is technically sound, hygienically maintained, and clean.

4.1 Attaching the Polisher/Brush

1. Select the appropriate polisher or brush for the task.
2. Insert the shank of the polisher/brush into the chuck of the low-speed handpiece.
3. Ensure the instrument is inserted as far as possible to prevent wobbling or detachment during operation.

5. Operating Instructions

1. Before using on a patient, run the instruments outside of the oral cavity to ensure there is no distortion.
2. Verify that the instruments are free from deformations, scratches, cracks, and tarnishes.
3. Bring the instrument to the required rotational speed (up to 15,000 rpm/min) prior to applying it to the object surface.
4. Operate with as little pressure as possible (approximately 50g, similar to writing pressure). Excessive pressure can lead to more heat generation, faster wear, and poorer working results.
5. Avoid tilting or levering the instruments, as this may increase the risk of breakage.
6. Use with a water spray system to prevent overheating and ensure smooth operation.

6. Maintenance

All instruments must be cleaned, disinfected, and sterilized before use. Efficient cleaning and disinfection are indispensable prerequisites for effective sterilization.

6.1 Cleaning and Disinfection

A mechanical method (Cleaning and Disinfection Device - CDD) is preferred. Manual procedures should only be used if a mechanical procedure is not available, due to significantly lower effectiveness and reproducibility.

6.1.1 Mechanical Cleaning / Disinfection Procedure

1. Place the instruments in the CDD using a small parts basket.
2. Start the program.
3. Remove the instruments from the CDD after the program is completed.
4. Check and package the instruments immediately after removal.

6.1.2 Manual Cleaning and Disinfection Procedure

Cleaning:

1. Immerse the instruments in a detergent solution and clean all surfaces with a brush.
2. Remove the instruments from the cleaning bath and rinse them thoroughly at least three times (at least 1 minute each) with water.
3. Check the instruments for cleanliness.

Disinfection:

1. Place the disassembled, cleaned, and checked instruments in the disinfection bath for the specified action time, ensuring they are sufficiently covered.
2. Remove the instruments from the disinfection bath and rinse them thoroughly at least five times (at least 1 minute each) with water.
3. Dry the instruments by blowing them off/out with filtered compressed air.

Important Considerations for Cleaning/Disinfection Agents:

• Ensure agents are suitable for cleaning instruments made of metals and plastics.
• If no thermal disinfection is used, a suitable disinfection agent with certified effectiveness (e.g., VAH/DGHM or FDA/EPA approval/clearance/registration or CE marking) must be used.
• Verify compatibility between the cleaning agent, disinfection agent, and the instruments.
• Strictly follow the manufacturer's instructions for concentrations, temperatures, action times, and follow-up rinsing.
• Use only freshly prepared solutions and sterile or low-microbe count water for rinsing.

6.2 Sterilization

Only the following sterilization process shall be used. Other sterilization processes (e.g., hot air, radiation, formaldehyde, ethylene oxide, or plasma sterilization) are not permitted.

Equipment: Pressure steam sterilizer, Disposable sterilization bag

Method:

1. First, place the instruments into disposable sterilization bags and package them.
2. Then, load the packaged instruments into the steam sterilizer.
3. Set steam sterilizer parameters: temperature 134 ℃, sterilization time 5 minutes, drying time 10 minutes.
4. Start the sterilizer and sterilizing cycle.
5. After a sterilization cycle is complete, remove the instrument after cooling.

7. Troubleshooting

• Instrument breakage/twisting: This can occur if the instrument head is thin, long, or large, or if unreasonable angles and excessive pressure are applied during use. Always use appropriate pressure and avoid tilting or levering.
• Poor polishing results or faster wear: This is often a result of applying too much pressure. Use light pressure (approx. 50g) for optimal results and instrument longevity.
• Overheating: Ensure a water spray system is used during operation to prevent excessive heat generation.
• Distortion or damage: Always inspect instruments for deformations, scratches, cracks, or tarnishes before use. Immediately dispose of any damaged or unbalanced instruments.

8. User Tips

• Achieving a great finish: Users report that these tips leave a nice finish and shine on resin. Experiment with different polisher types in the kit to find the best result for your specific material.
• Sterilization is key: As confirmed by user questions, these polishers are sterilizable. Always sterilize by autoclave before each use to prevent infection.
• Complete and convenient: Many users appreciate the completeness of the kit and its good value. The included box helps keep the various polishers organized.
