This article talks about some common problem of dental handpiece, and also tells us the solutions.

Modern high-speed dental handpiece (that is, the turbine head) are driven by gas-driven and high-speed rotary bur to cutting teeth. Speed and accuracy under pressure at rated rotation directly affects the dentist's clinical results. rated rotation speed under the pressure the higher the better concentricity sleeve, the more accurate the drilling area, the dentist more easily, while the lower level of the patient's pain. Thus the dental handpiece at the rated pressure of the rotation speed is normal or not is particularly important.
Dentists often put across a new dental bur do not move the needle still drilling teeth, while it is normally driven by air pressure. So the user is usually by adjusting the air pressure on the way to get a higher speed to get a good cutting result. In fact, it indicates a potential failure, the more pressure the higher the adjustment speed increased damage to handpiece will eventually lead to undesired cutting effect no matter how high the air pressure can not achieve. So we must replace the handset because of damage to the teeth of the dental drill is used; the impact of its internal bearing life factor in "fatigue life" and "grease life" is the most prominent. Therefore, in the usual course of the following three points should be noted:
1. Two high-speed handpieces used interchangeably
bearing in use has been a high speed rotating, ball bearing then kept in the loop to exert force to the bearing inner ring, with the bearing over time will lead to a "mechanical fatigue", and thus directly affect the bearing life. Dentists usually use standard treatment table, with two high-speed dental handpieces, if the dentist uses one for some time (ten minutes is appropriate) replace the other one, that is, two alternately, this can greatly ease because of "fatigue" and the life of the bearings on the impact. Thus largely extend the life. According to statistics, almost 60% of the bearing is damaged because of the "fatigue". 2. Cleaning and lubrication of the bearing is also a very important.
Cleaning is to prevent foreign matter from entering the bearing and the bearing inner and outer rings with increasing ball Mount Sassafras, which is a detergent and lubricant within the mobile water and gas foreign exchange process. Lubrication is to reduce the ball inside and outside the ring and bearing between the Friction forces, making the handpiece to high-speed rotation. We want to use in the lubrication oil of professional oil is a liquid, in the mobile bearing, while a large number of high-speed rotation loss and makes the bearings quickly in a "dry" state, so to give before each use for oiling, dental handpiece in the lubrication of bearings in a timely manner the state.
3. Depending on the brand and model of dental handpiece use the appropriate size of the drive air pressure.
4. There should be a professional maintenance about three months later using the dental handpiece. This maintenance work is best professionals to operate in accordance with certain procedures.
