Diamond burs are typically used for precision shaping and polishing, but as diamond is one of the hardest known materials, they are often used to cut through zirconia or grind porcelain during the preparation and placement of veneers and crowns.
What are diamond burs used for?
Dental diamond burs are most often used to grind away tooth tissue, usually enamel. The grinding motion of a diamond bur leaves a rough surface. They are needed when a cut requires extreme precision. Carbide burs are most often used when preparing cavities for fillings, shaping bone and removing old fillings.
Is an advantage of a diamond bur?
Advantages of diamond burs:
Diamond burs enable faster and smoother cutting, and are needed when a cut requires extreme precision. Diamond burs with a finer grit can create a higher polish, and are therefore more appropriate for precise work instead of removing large pieces of material.
What is the difference between diamond and carbide burs?
Overall carbide and diamond burs are functionally different. When using a carbide bur the bur is using small blades to slice away small pieces of the tooth while with diamond burs you are grinding the tooth down and leaving it with a rough surface that requires polishing later on with a separate tool.
What type of burs are used to remove decay?
Dental caries are removed using a round tungsten carbide bur at a slow speed. Good sizes to select are sizes two, four, six, or eight. Using a round tungsten carbide bur at a slower speed removes only a minimal amount of dental hard tissue while more effectively removing the softer areas of decay.
How much do diamond burs cost?
“Disposable diamond burs cost as little as 85 cents, while reusable ones cost as much as $8.” Dentists also focus on the longevity of a bur, and whether they can be sterilized and reused. In Klein’s experience, diamond burs offer a high-quality, smooth cut. They often are the bur of choice for crown preps and fillings.
What are the 3 types of Bur shanks?
All burs have a shank and a head. There are three main types of shank – Long Straight Shank (HP), Latch-type Shank (RA) and Friction Grip Shank (FG).
What happens if you swallow a dental bur?
Accidental ingestion or inhalation of dental objects during daily clinical practice may cause various clinical complications such as damage to the digestive tract, abscess formation, peritonitis, septicemia, pneumonia, foreign-body granuloma, fistulas and duodenocolic fissures.
Do finishing burs cut enamel?
Diamond burs are most commonly used with high speed handpieces, meaning they are most commonly available as a friction grip shank. Diamond is the hardest material available and is used to grind away tooth tissue, usually enamel. The grinding motion of a diamond bur leaves a rough finish.
How diamond burs are made?
They are normally made of stainless steel, diamond grit or particles, and tungsten carbide and fitted to a dental drill incorporating an air turbine. The dental bur was developed <300 years ago  and still widely used. The dental bur [4,8,9] has three parts: the head, the neck, and the shank.
What are carbide burs used for?
