How to maintain dental handpieces

The sterilization and maintenance of dental handpieces should be done by a dedicated person. No matter how busy the work is, these tasks must be completed step by step, and "cutting corners" must not be done. The so-called "maintenance-free" handpieces only have special processing on the ball surface, so that the handpiece will not adhere to debris and the lubricant will not be lost during use. But the rest of the bearing (such as O-rings, etc.) still need maintenance, so don't ignore the regular maintenance of these handpieces.

Flushing is an important preparatory work for handpiece maintenance. When flushing, use a pressurized detergent nozzle to aim at the air inlet at the tail of the handpiece, and use the detergent to rinse the debris inside the handpiece. Then connect the handpiece to the dental chair, do not remove the needle (most handpieces should not be removed when the needle is running), start the machine, and rinse the remaining debris and detergent in the handpiece.

The closer the handpiece is to the heat source, the more likely its internal components are to be damaged and denatured. The heat source of the high-temperature and high-pressure sterilizer is at the bottom, so the sterilization paper bag containing the handpiece should be placed on the top layer of the sterilizer, as far away from the heat source as possible, and not on the bottom layer.

Most sterilizers have a high-temperature drying process after completing the sterilization work. This is an important part of preventing the  from rusting. If this process fails, it should be repaired in time.

In order to ensure the normal operation of the , appropriate needles should also be selected. Large-headed needles and long needles should be used as little as possible, as they will greatly increase the load on the ball; needles that are too small will slip, and needles that are too large will get stuck in the fixed groove; severe wear of needles will increase the working load of the bearing.

The air pressure that drives the  is too high or too low, which will affect the normal operation of the  and cause damage to the . Different s have different optimal working air pressures, so the air pressure should be adjusted according to the manufacturer's regulations before starting work every day. When the gas reaches the  from the barometer, the air pressure generally drops by 1.0psi, and this difference should be added in the calculation. In addition, you should always pay attention to the noise generated when the  is working, and adjust the air pressure in time when abnormalities are found.
