Precautions for using Dental handpiece

The damage of dental handpieces is mainly due to the damage of the bearings inside the handpieces. For dental drills used in the oral department, the factors that affect the life of the internal bearings are "fatigue life" and "lubrication life". Therefore, the following four points should be noted during normal use:

1. Alternate use of two high-speed handpieces.

During the use of the handpiece, the bearings are constantly rotating at high speed. At this time, the balls in the bearings are constantly applying force to the inner and outer rings of the bearings. After a long time of use, it will cause "mechanical fatigue" of the bearings, which will directly affect the life of the bearings. Doctors usually use standard treatment tables with two high-speed handpieces. If the doctor uses one handpiece for a period of time (preferably ten minutes) and then switches to another handpiece, that is, the two handpieces are used alternately, this can greatly alleviate the impact of "fatigue" on the life of the handpiece bearings. Thereby greatly extending the service life of the handpiece. According to statistics, almost 60% of the handpiece bearings are damaged due to "fatigue".

2. Cleaning and lubrication of the bearings is also a very important consideration.

Cleaning is to prevent foreign matter from entering the bearing and increase the friction between the ball and the inner and outer rings of the bearing. This is a process of replacing water and foreign matter in the air path of the  with detergent and lubricant. Lubrication is to reduce the friction between the ball and the inner and outer rings of the bearing so that the  can rotate at high speed. In terms of lubrication, we must use professional  lubricants.  lubricants are liquid. When the  bearing rotates at high speed, a large amount of it will be lost, causing the bearing to be "dry" quickly. Therefore, we should strive to fill the  with oil before each use to keep the  bearing in a lubricated state in time.

3. Choose the compressor air pressure according to different brands and models of the dental handpiece.

4. The dental handpiece should be professionally maintained in time after about three months of use. This maintenance work is best performed by professionals in accordance with certain steps.
