Is an advantage of a diamond bur?

Diamond burs enable faster and smoother cutting, and are needed when a cut requires extreme precision.

What are diamond burs used for in dentistry?

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.

What is the difference between carbide and diamond 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.

Which bur is 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.

What is the most efficient rotary cutting instrument?

Conclusions: The tested carbide bur showed greater cutting efficiency than the tested diamond rotary cutting instruments when used with the electric handpiece. The electric handpiece showed a higher cutting efficiency than the turbine, especially when used with the carbide bur, probably due to its greater torque.

How are diamond burs made?

Conventional diamond burs are made by plating small industrial or mineral diamond particles on stainless steel shanks by a galvanic process. This technology dates from the 1950s and has some inherent limitations, owing to the heterogeneity of the grain shapes, the difficulty of automation, and the short lifetime.

What is a cross cut bur?

Round – Fine Cross Cut

Fine Cross-Cut burs feature traditional head shapes with maximum density cross-cuts in the bur blades to dramatically increase cutting efficiency while simultaneously decreasing undesirable chatter, friction and clogging. Perfect for rapid reduction or crown removal.
