What are the categories of dental burs?

The diamond bur is a very common tool used in dental practice. It is a bur that is used on the drill of a dental handpiece, and we talked about how it works in our last article. So, do you know about such a small, but diverse tool? Here we will classify it.

Dental handpiece bur classification

• Classified by function: high speed, low speed (16, 30, 45jrpm)
• Classification by length: standard, short shank, ultra-short shank (17-26mm)
• Classification by coarse and fine: coarse, standard, fine, ultra-fine
• Classification by use: restoration preparation of abutment teeth, preparation of cavity type, etc.
• Classification by form: various forms
• Classification according to the type of steel sand: natural, artificial
• Classification by service life: disposable, repetitive

What do we need to pay attention to when we use diamond bur with the dental handpiece? Using diamond bur correctly can bring great convenience to our work.

What should be noted when using the bur?

1. The selected dental handpiece bur should not be easily deformed, have high stability and fracture resistance, no tip chipping or desanding, good concentricity in rotation.
2. Please pay attention to the FG mark on the package, which identifies the bur used on dental high speed handpiece
3. Should pay attention to the speed of dental bur, especially when operating the head of large diameter bur and coarse grain bur, the speed of bur is too high will generate too much heat, causing damage to the pulp and dental tissue.
4. After disinfection or cleaning, dry the bur and store it in a clean and moisture-free environment.
5. Do not force the bur into the dental handpiece, check the dental handpiece and bur carefully if there is difficulty in installation.
6. Cutting should be applied to the appropriate force (30 ~ 60g), sequential and effective cutting dental tissue.
7. The bur should be disinfected and sterilized before each use. Always use nylon brush or ultrasonic cleaner to clean the bur. autoclave the bur at 135 degrees for at least 10 minutes.
8. Tungsten carbide bur after use, should be cleaned after using high temperature and high pressure disinfection, do not use chlorine-containing disinfectant to soak the turning needle, otherwise it will cause tungsten steel turning needle rust blunt.
9. Clinically common diamond bur tip than the tail end wear faster, then pay attention to timely replacement bur, so as to avoid low cutting efficiency.
10. The use of dental handpiece cooling water should reach 50ml per minute.
