More types of mobile phones, and the structure can be divided according to speed and low-speed high-speed mobile phones, high-speed mobile dental handpiece using high pressure air driven turbine handpiece for micro turbine speed can be up to 300,000 to 500,000 r / min, bur cutting speed can be up to 15m / s, while the low-speed mobile dental handpiece because it is gear, speed can be transferred per minute for thousands of 30000 rpm.

what determines the life of diamond burs
Bur, especially diamond bur dental doctor is the most frequently used tools. But because of its relatively low cost, many doctors ignore its maintenance and
Maintenance. And there are many doctors that: "I use *** brand bur, used once and throw away!" The doctor said these words to express the meaning of non-
Often clear that this car has Gutta Percha Points been sterilized needle after grinding cutting ability decreased significantly. What causes this phenomenon it?
Are summarized as follows:
First, the reasons for sterilization
There are many doctors use a 2% glutaraldehyde for disinfection, you know, glutaraldehyde has some corrosion on the metal, and the disinfection process soaking time than
Long. So there are many doctors complain especially tungsten steel bur bur rust problems.
For steel and tungsten carbide bur is recommended that:
1, autoclavable, for disinfection prior to remain in the blood stains on the bur and tooth tissue debris and timely water rinse, if necessary, use a brush to clean.
2, good quality and bad bur bur sterilized separately to avoid mutual influence
Second, the high-speed impact of the turbine water spray
Because dental chair using a certain time produced a change or anthropogenic causes water becomes smaller. At this point bur rotating at high speed process can not be effectively cooled, would produce a certain
Was loss.
Recommends regular inspection of water meets 50 ml / min standard
Third, the choice of bur
You doctor should pay attention to the difference in the consumer's selection of diamond bur is synthetic or natural diamond emery. The difference between them is that the former will
Decreased cutting force there dental scaler grinding abrasion resistance of the latter is relatively long.
The above is a synthetic diamond micro-graph, edges relatively simple, polished edges after cutting ability has decreased significantly. Synthetic diamond bur lower cost in the market
The sales price is relatively uniform, no matter what form the thickness of both a price.
