5. Setup and Installation

5.1. Setting up External Dental Equipment:

Ensure your dental unit's water supply system provides a pressure of 0.7bar-2.2bar (70-220kPa) and a temperature of up to 40°C.

Adjust the air supply pressure to obtain 3.5bar to 4.5bar (350 to 450kPa) at the external dental equipment.

⚠️ Excessive air pressure can cause cracks or ruptures in the powder chamber and cover, potentially leading to human injury.

5.2. Installation and Connection:

⚠️ Before installation, ensure the quick connector, power jet handpiece, powder chamber, powder chamber cap, tail connector, air inlet pipe, and air outlet pipe are completely dry. Use a 3-way syringe for drying.

Connecting Power Jet Handpiece and Quick Connector:

1. Use a 3-way syringe to dry the power jet handpiece tail connector and the quick connector.
2. For AirJet 1S and AirJet 2: Directly insert the quick connector into the Power Jet Handpiece tail connector, then tighten the quick connector.
3. For AirJet 1: Directly insert the quick connector into the Power Jet Handpiece tail connector, then tighten the quick connector.

Figure 8: Connection method for AirJet 1S and AirJet 2.

Connecting Handpiece to Main Body:

After drying the inside of the handpiece and the connector of the main body, directly insert the handpiece into the interface of the main body.

6. Operation

6.1. Adjusting Water Flow:

Before loading the prophylaxis powder, adjust the water flow so that the power jet handpiece receives an even amount of water.

6.2. Loading Prophylaxis Powder:

⚠️ Use only powder provided or recommended by VOLDENT. Ensure the powder chamber is absolutely dry. Do not exceed the 'MAX' limit. The opening of air inlet and outlet pipe should not be covered by powder. Clean the threads of the powder chamber before screwing on the cap. Do not shake the device as this could cause the powder to clog the tubes.

1. After connecting the Power Jet Handpiece, unscrew the powder chamber cover.
2. Put the prophylaxis powder into the chamber.
3. Clean any powder at the thread position of the chamber cover.
4. Tighten the chamber cover.

6.3. Air Volume Switch Operation (for AirJet 2 only):

The AirJet 2 power jet handpiece has two gears. Rotate the air volume adjustment switch to select between:

• Supragingival sandblasting (right)
• Periodontal sandblasting (left)

6.4. Supragingival Scaling:

For supragingival scaling, adjust water and air flow to achieve desired cleaning and polishing effects. Wear a face mask and eye protection. Place absorbent cotton rolls under the lips and use a high-speed evacuator. Do not direct the nozzle directly at the tooth surface; maintain a distance of 3 to 5mm and vary the angle between 30 to 60 degrees. After treatment, polish the teeth surfaces by setting the water flow rate to the maximum.

Figure 10: Supragingival sandblasting technique.

6.5. Periodontal Scaling:

⚠️ The air powder jet is powerful. It can cause injury to the gums or an emphysema if air is introduced into soft tissue spaces. Do not direct the nozzle directly at the gum tissue or into the gingival sulcus.

⚠️ After treatment, the keratin and protein layer on the tooth surface are completely removed. Advise patients that for 2 to 3 hours following treatment, they should neither smoke nor consume food or drinks that could strongly color the teeth (e.g., tea, coffee).

Installation of Periodontal Nozzle:

1. Take the periodontal nozzle and assemble it to the top of the handpiece according to the positioning direction.
2. Use the wrench to lock the locking cap to the nozzle.
3. After inserting the nozzle in the correct direction, screw on the locking cap, use a wrench to lock the nozzle locking cap, and remove the wrench after locking.

Figure 11: Handpiece with 360-degree rotation for easier access.

Periodontal Sandblasting Operation:

1. After filling the powder, spray it in an outer container for 1-3 seconds to ensure even air and water spray before treating the patient.
2. Hold the powder jet handpiece in a pen-holding position.
3. When performing normal periodontal scaling, use the nozzle to remove plaque from the periodontal pocket (1-3mm below the gingival) with up and down lifting and scaling motions.
4. Scaling is recommended for less than 5 seconds per periodontal pocket site.
5. Ensure the water channel of the handpiece is unobstructed. Adjust water volume and air pressure according to dental plaque or pigment conditions. Avoid staying too long in one area.

7. Maintenance

7.1. Daily Maintenance:

• At the end of each day, use long and short needles to clean each pipeline of the equipment.
• Replace the powder chamber cap seal ring, seal ring 1, and seal ring 2 every 6 months.
• Perform ultrasonic cleaning of the handpiece with hot water soak once a week.

7.2. Cleaning, Disinfecting, and Sterilizing:

Powder Cleaning:

1. Uncover the chamber cap and empty the powder chamber.
2. Keep the unit operating after shutting off the water supply. Use compressed air to blow out remaining water and powder in the pipe.
3. Blow out remaining powder in the chamber and connector with dry compressed air.

Handpiece and Body Cleaning:

1. Remove the handpiece.
2. Insert the cleaning nozzle into the handpiece until a "click" sound is heard, ensuring it's securely fastened.
3. Use a 3-way syringe to blow air inside the handpiece through the cleaning nozzle for 3-5 seconds to thoroughly clean the handpiece tubes.
4. Wash the powder chamber cap, cap ring, cap dome, and handpiece with distilled or deionized water.
5. Clean the threads of the powder chamber, body surface, and handpiece surface with alcohol (ethanol, isopropanol).
6. If the nozzle is clogged, use a thru-needle to unblock.

Sterilization:

Enclose the handpiece in a sterilization bag and seal the bag.

Sterilize the handpiece at up to 135°C in the autoclave (134°C for 20 minutes or 132°C for 15 minutes).

⚠️ Only the handpiece can be autoclaved under high temperature and pressure.

⚠️ Ensure no chemical liquid is on the handpiece surface and it is completely dry before sterilization.

⚠️ Do not clean or scour this device with high acidity cleanser or disinfectant.

⚠️ Submerge only the handpiece in a disinfectant bath. Do not submerge the unit in a disinfectant bath.

⚠️ It must be sterilized before first use and after each patient use.

⚠️ Clean up within 30 minutes after treatment; high temperature and high pressure sterilization treatment should be taken place within 2 hours after cleaning.

8. Troubleshooting

In case of any fault that could not be solved by the above methods, please contact your dealer or the nearest service center.
