The dental handpiece is very important for dental surgery. It requires regular maintenance to prolong its service life. Let’s see how to maintain it.

Clean 

After using the dental handpiece, clean it as soon as possible, otherwise, the dirt will solidify and be difficult to clean. Before unloading the needle, clean the debris on the working head with water mist, and then scrub it with 75% alcohol. Or use ultrasonic handpiece cleaning machine to clean. The cleaning methods depend on the specific situation of each clinic.

Take out the needle

After use, when removing the needle, just loosen (turn) the key for 1 / 4 turn. If it is loosened too much, the three-leaf spring will be pushed to the rear cover and damaged. After each use, take out the needle in time to facilitate the recovery of the mechanical part of the needle clamp of the handpiece.

Refuel

• The pneumatic fuel injection tank is the most ideal lubrication tool. It can not only lubricate the handpiece, but also clean the bearing and wind wheel.
• Before using the fuel injection tank, first remove the needle (reverse rotation of the spiral mobile phone by 1 / 4 turn), wrap the machine head with paper, and insert the nozzle of the oil tank into the air inlet of the handpiece to ensure sufficient air pressure.
• The pneumatic fuel injection tank must be used vertically for 2-3s each time.
• For 2-hole dental handpiece, the nozzle aligns with the large hole. For the 4-hole handpiece, nozzle is sprayed against the second largest hole.
• In the case of oil dropping method, drop 4 drops of oil into the large hole, and then use an air gun to intermittently blow air into the oil filling hole for 30s.
• It is strictly prohibited to lubricate with industrial lubricating oil to prevent patients from poisoning.
• Dental handpieces that are not used for a long time should be fully oiled, sealed, and stored.
