5. Setup

Before use, ensure that the handpiece is technically sound, hygienically maintained, and cleaned. The polishers are designed for use with a contra-angle handpiece.

Inserting the Polisher:

1. Select the appropriate polisher for the task.
2. Insert the shank of the polisher into the chuck of the contra-angle handpiece.
3. Ensure the polisher is inserted as far as possible to prevent half-way chucking, which can lead to instability and potential injury.
4. Verify that the polisher is securely seated before operation.

6. Operating Instructions

Before Application:

• Prior to first use on a patient, sterilize the rotary instruments.
• Run the instruments outside the oral cavity to ensure there is no distortion.
• Check for any deformations, scratches, cracks, or tarnishes. Immediately dispose of damaged, deformed, or unbalanced instruments.
• Bring the instrument to the required rotational speed before applying it to the object surface.

During Operation:

• Operate with as little pressure as possible (approximately 50 g, similar to writing pressure). Excessive pressure leads to more heat development, faster wear, and poorer working results.
• Avoid tilting or levering the instruments, as this may increase the risk of breakage.
• Always use a water spray system during operation.
• Choose the most appropriate polisher type for each case and follow the general method for polishing.

7. Maintenance

Proper cleaning, disinfection, and sterilization are crucial for the safe and effective reuse of these dental instruments. All instruments must be cleaned, disinfected, and sterilized before each use.

Cleaning and Disinfection:

A mechanical method (Cleaning and Disinfection Device - CDD) is preferred due to its higher effectiveness and reproducibility. Manual procedures should only be used if a mechanical procedure is unavailable.

Mechanical Cleaning / Disinfection Procedure:

1. Place the instruments in the CDD using a small parts basket.
2. Start the certified program (e.g., thermal disinfection with A0 value > 3000 or at least 5 min at 90℃/194℉).
3. Ensure the program is suitable for the instruments and has sufficient rinse cycles.
4. Use only sterile or low-microbe count water (max. 10 microbes/ml) with low-endotoxin content (max. 0.25 endotoxin units/ml) for follow-up rinsing.
5. Ensure filtered air (oil-free, low microbe and particle content) is used for drying.
6. Remove instruments after the program is completed and check immediately.

Manual Cleaning and Disinfection Procedure:

1. Immerse instruments in a freshly prepared detergent solution and clean all surfaces with a brush.
2. Remove instruments from the cleaning bath and rinse thoroughly at least three times (at least 1 min) with water.
3. Check the instruments for cleanliness.
4. Place the cleaned instruments in a disinfection bath for the specified action time, ensuring they are sufficiently covered.
5. Remove instruments from the disinfection bath and rinse thoroughly at least five times (at least 1 min) with water.
6. Dry the instruments by blowing them off/out with filtered compressed air.

Note: Always comply with the concentrations, temperatures, and action times specified by the manufacturer of the cleaning/disinfection agent.

Sterilization:

Only pressure steam sterilizers with disposable sterilization bags should be used. Other sterilization processes (hot air, radiation, formaldehyde, ethylene oxide, plasma sterilization) are not permitted.

Sterilization Procedure:

1. Place the instruments into disposable sterilization bags and package them.
2. 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.
5. After a sterilization cycle is complete, remove the instrument after cooling.

The rapid sterilization process is generally not permitted.

8. Troubleshooting

• Instrument Breakage/Twisting: This can occur if the instrument head is thin, long, or large, or due to unreasonable angles and excessive pressure during use. Always use a "feather touch" and avoid tilting or levering.
• Poor Polishing Results: Often caused by excessive pressure or incorrect speed. Ensure you use light pressure and the recommended RPM.
• Instrument Distortion/Damage: Always inspect instruments before use. If any distortion, scratches, cracks, or tarnishes are present, dispose of the instrument immediately.
• Infection Risk: Ensure proper sterilization procedures are followed for each use. Incomplete sterilization poses a significant health risk.

9. User Tips

• Users have reported that these polishers provide a very nice and excellent shine to restorations.
• The kit is comprehensive, often including various types of brushes (e.g., medium and thick hair wheels, felt, soft cotton) and silicone tips with different grits (e.g., medium and fine), allowing for a full range of polishing steps.
• The product is considered to be of good quality and effective for resin polishing.

10. Frequently Asked Questions (FAQ)
