Dental Carbide Burs

Burs come in various shapes and sizes, so standard numbering systems were devised to make them easier to identify. There are two main numbering systems in use: U.S. and ISO (International Standards Organization). Carbide burs are typically numbered from 1 to 4 digits, depending on the bur’s size. You can make the right choice when selecting a dental bur when you know the five types available.

1. Carbide burs

The most common uses include filling cavities, removing old fillings, and shaping bone. The following are advantages of carbide burs:

-The surface is smoother than that of diamond bursts.

-Other types of burs also vibrate and chatter more than carbide burs.

2. Diamond burs

The most common uses are: Cutting porcelain and polishing.

Diamond bursts have the following advantages:

-Faster and smoother cuts can be achieved with diamond burs, which are also needed when extreme precision is required. Compared to diamond burs with coarser grit, diamond burs with finer grit provide a better polish and are better suited to precision work versus removing large pieces.

-It will help if you focus on a natural diamond outlast a synthetic one when buying a diamond bur.

3. Ceramic burs

Adjusting acrylic pieces is the most common use. Ceramic burs have the following advantages:

It is easier to adjust acrylic pieces in acrylic burs made from ceramic since they don’t conduct heat as much as other burs. Thermoplastics can also be adjusted using these burs. Burns are also reduced when burs are changed when cutting at a cooler temperature.

4. Steel burs

Used most commonly to remove dentin and prepare cavities. Steel burs have the following advantages:

The combination of high-speed steel burs and wear-resistant carbides provides abrasion resistance and good edge retention. Low maintenance and flexibility make them an ideal choice. In contrast to other dental burs, these tend to chip and dull more quickly.

5. Different shapes of dental burs

Dentists use a wide range of dental burs, each for a different purpose with its advantages. When paired with an inefficient shape, even the best material may not be as effective as it could be. Round, pear, and crosscut tapered shapes are the most common shapes.

Pearl burs are ideal for creating access points, preparing cavities, and balancing roots of smaller teeth. Round burs are commonly used to prepare cavities and create access points, but they may also be used to create channels for blades when removing teeth. Tapered fissure bursts cut very efficiently, so they produce less debris. Consequently, they are ideal for reducing crown height and sectioning teeth with multiple roots.

Tungsten carbide dental burs (carbide burs): This material is becoming the replacement for the older steel burs. Tungsten carbide has three times the rigidity of steel and is highly efficient, as well as being highly durable due to its outstanding wear-resistant properties.

We can distinguish between two main types: Tungsten carbide dental burs (carbide burs): This material is becoming the replacement for the older steel burs. Tungsten carbide has three times the rigidity of steel and is highly efficient, as well as being highly durable due to its outstanding wear-resistant properties.

The vast majority of commercially available dental burs are made of synthetic diamond and it is less common to come across natural diamond burs. Manufacturers who use natural diamond usually emphasise this characteristic, as it gives the burs greater quality, efficiency and durability.

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.
