Dental Handpiece Maintence Methods

The damage of the dental handpiece is mainly due to the damage of the bearing inside the handpiece. For the dental drill used in the dental department, the “fatigue life” and “lubrication life” are the most prominent factors affecting the inner bearing life. Therefore, we should pay attention to the following three points during the usual use.

  1. Use two high-speed dental handpieces alternately. During the use, the bearing is always rotating at high speed. At this time, the ball in the bearing continuously applies force to the inner and outer rings of the bearing, which will cause the mechanical fatigue of the bearing for a long time. This directly affects the life of the bearing. Dentists usually use a standard configuration of the treatment table, which is equipped with two high-speed handpieces, If the dentist uses a handpiece for a period of time (10 minutes is appropriate) , he has better replace the use of another handpiece, that is the two handpieces are used interchangeably, which greatly reduces the impact on the life of the handpiece bearing due to “fatigue”. This greatly extends the life of the handpiece. According to statistics, almost 60% of dental handpiece bearings are damaged due to “fatigue”.
  2. Bearing cleaning and lubrication is also an important consideration. Cleaning is to prevent the impuritiesfrom entering the bearing and increase the friction between the ball and the inner outer rings of the bearing. This is a process of replacing the water and impurities in the gas path of the handpiece with detergent and lubricating oil. Lubrication is in order to reduce the friction between the ball and the inner and outer rings of the bearing, the handpiece can rotate at a high speed. We use professional handpiece lubricants for lubrication. Dental handpiece lubricants are liquid. When the handpiece bearings rotate at high speed, there will be a lot of lubricants loss and the bearings will be in a “dry” state. Therefore, we must strive to fill the handpiece before each use, so that the handpiece bearings are lubricated in time.

 

  1. According to different brands and models of handpieces, select the corresponding driving pressure

 

You should have a professional maintenance of your handpiece after using three months or so.

This maintenance work is best performed by a professional in accordance with certain steps.
