Dental Bur Operating Guide

Cleaning of dental burs

First, surface disinfect the used needles by soaking them for 30 minutes. The disinfectant is 2% glutaraldehyde. After soaking, use a small-headed toothbrush to clean the textured part of the bur, and then rinse with clean water.

1. 1.Disinfect the needle before each use. Burring needles should be cleaned frequently using a nylon brush or ultrasonic cleaner. Autoclave bur needles at 135 degrees.
2. 2.All bur needles can be cleaned using ultrasonic waves. During cleaning, the bur needle box should be used to hold the bur needles upright to avoid damaging the bur needles due to collision with each other during cleaning and shock.
3. 3.After use, the bur needle should be immediately put into a container containing detergent and disinfectant, and both should contain anti-rust agents. Avoid using strong acid and alkali disinfectants and some strong chemical reagents.

How to disinfect dental burs

Because the burs for dentistry are operated in the patient's mouth and often comes into contact with saliva, blood, and mucosal tissue, the selection of disinfectants is relatively strict. Disinfectants with good sterilization effects and low irritation and corrosion to metals should be selected. Clinically, 20 mg/L E Chemical disinfectants such as dialdehyde are used to disinfect bur needles.

Cleaning and disinfection of bur needles is very important. Because it is related to protecting the health of doctors and patients and avoiding cross-infection, the cleaning and disinfection of dental burs. On the basis of using "one person, one machine" for dental handpieces, it is very important to promote the work of "one dedicated bur for one person" and should be fully paid attention to. attention of the majority of medical staff.

How to use the dental burs

When grinding teeth, you should use the "light touch" technique and do not apply force to cause the cutting force of the bur to decrease. At present, most of the motors we use are pneumatic motors. Pressurization will reduce the speed of the needle or even stop it, thereby reducing the cutting force of the needle. Therefore, when grinding the tooth, do not apply pressure in the direction of the tooth. Instead, grind it with a "light touch" technique, and even a little "lifting" force is required.

When preparing the tooth, it is necessary to first grind a groove of a certain depth on the tooth, and then pull and grind the tooth tissue left and right on the basis of the groove of a certain depth.

Things you should pay attention to when using turning dental burs

1. 1.The selected surgical bur should be difficult to deform, have high stability and anti-fracture ability, no tip collapse or desanding, and good concentricity during rotation.
2. 2.Appropriate force (30-60g) should be applied when cutting, and the dental tissue should be cut sequentially and effectively.
3. 3.Pay attention to the speed of the bur, especially when operating large-diameter bur heads and coarse-grained burs. Too high a speed of the bur will generate excessive heat, causing damage to the dental pulp and dental tissue.
4. 4.Do not force the bur into the turbine. If installation difficulties occur, carefully check the handpiece and bur.
5. 5.Please pay attention to the FG mark on the package. This mark is the bur used on high-speed turbines.
6. 6.Disinfect the needle before each use. Burring needles should be cleaned frequently using a nylon brush or ultrasonic cleaner. Autoclave burs at 135 degrees for at least 10 minutes.
7. 7.After disinfection or cleaning, dry the bur needle and store it in a clean and moisture-free environment.
8. 8.It is common in clinical practice that the tip of the emery bur wears faster than the tail end. At this time, pay attention to replacing the bur in time to avoid low cutting efficiency.
9. 9.When using turbine cooling water, it should reach 50ml per minute.
10. 10.After using the tungsten steel bur, it should be cleaned and disinfected with high temperature and high pressure. Do not soak the bur with chlorine-containing disinfectants, otherwise the tungsten steel bur will rust and become dull.
