With so many shapes, types, blade configurations and head angles of dental burs, it’s difficult to keep track of their various uses. We’re starting a new segment on our blog showcasing specific dental burs and what sets them apart from the rest.
We’re kicking off this series with the 330 dental bur. This operative carbide has one of the most used shapes. Its pear shape is very effective for minimally invasive cavity preparations, ensuring that there isn’t too much tooth structure being removed. The 330 dental bur is also beneficial in removing old materials in the tooth, such as amalgam.
Carbide burs are made from tungsten carbide, which is three times stronger than steel. Their hardness makes them ideal for cutting work. Since the 330 dental bur is a carbide, it can maintain a sharp cutting edge and can be used multiple times without becoming dull. Unlike diamond burs, they don’t grind the enamel, leaving a smoother surface.
The
330 dental bur is available in friction grip, right angle and friction grip short shanks. It is available in sizes .10, .018, .012, .014, .006, .008 and .009. To get a better idea on what all the sizes mean, check out the image below.
Dental burs are vital in dental offices, and it is important to understand the unique use of each bur to ensure they are correctly used for procedures. Stay tuned for the next bur in our series: the CeraTip.
