Clinical Uses of a Carbide Bur

Material

Tungsten carbide burs as the name suggests are made from tungsten carbide. A material that is over 3 times more robust than steel. Due to their durability tungsten carbides have become a key part of dental practitioners’ arsenal.

Tungsten carbide is a coating created through a Powder Metallurgy process that mixes powdered tungsten carbide and cobalt and uses a binding material and pressure to bind them together. 

Tungsten Carbide Burs Dental Uses

Tungsten carbide burs can be used for a variety of dental procedures due to their cutting ability and low vibration. Common uses for dental carbide burs include preparing cavities, shaping bone, and removal of old dental fillings. Additionally, these burs are preferred when cutting amalgam, dentin, and enamel for their quick cutting ability. 

In general, tungsten carbide burs are useful for the rapid reduction of a surface due to their superior cutting ability and wear-resistant blades. This is especially true for burs with channels that increase their cutting ability and efficiency.

Advantages

Due to tungsten carbide burs having extremely strong and sharp blades the bur is able to cut away and leave a smoother surface than other burs. This is especially true when compared with the popular diamond bur. Diamond burs have a grind action which leaves a rougher surface that requires finer polishing later on. Additionally, in comparison to other bur materials carbide burs have less chatter or vibration. Carbide burs also have greater longevity than most other bur types due to the hardiness of the material. This allows dentists to save money while not having to worry about switching burs mid-procedure. They are also tougher than their steel counterparts which struggle with brittleness.
