Diamond burs are a versatile tool used for a variety of applications in dentistry and other industries. They are often used to place final shape and minor details on dental restorations, but they can also be useful for a number of other procedures such as metal deburring. In addition, they are frequently used to shape the surface of zirconia and grind porcelain for crowns or veneers. They are a great choice for a variety of hard materials including ceramics, steels, and stones and can be found in a number of different shapes and grit sizes.
There are a few important things to keep in mind when choosing the right type of diamond bur for your needs. First, it is essential to know the differences between carbide and diamond burs. Carbide burs are designed with small blades that slice away pieces of the tooth, while diamond burs are coated with diamond particles and are much softer. Both have their own specific benefits, but it is important to have a good understanding of both types in order to determine which one is best for the task at hand.
Another important consideration is the shape and cut style of the diamond bur. The shape and cut style will determine how the bur is used, and can have an impact on the quality of the result. For example, a round tungsten carbide bur is usually used to remove dental caries, and it is helpful to select a size that is appropriate for the area being treated. This will reduce the risk of affecting adjacent teeth with the diamond bur’s cutting surface. In addition, specialized restorative burs are available to prepare the floor of the mesial and distal teeth in Class II cavities. These angled burs will reduce the risk of affecting the tooth’s adjacent surface with the diamond bur’s cutting edge.
When performing a procedure that requires a higher level of precision than what is achievable with a carbide bur, a diamond bur should be utilized. This will ensure that the preparation is completed with minimal damage to the tooth and with a high-quality finish.
Choosing the right grit size is also important when using a diamond bur. A higher grit will be more aggressive and should be used for rougher work, while a lower grit will be more delicate and can be used for finer finishes. It is important to lubricate the bur with water or 412 Slick Lube during use to prevent any unnecessary damage and to increase its lifespan.
Lastly, diamond burs are available in a variety of shank types, and it is vital to choose the correct size for your handpiece. In general, diamond burs with a friction grip will fit most standard rotary handpieces, but they can be used in any flex shaft that accepts 3/32 in (2.35 mm) shanks. These include the Foredom and Dremel rotary handpieces. This will provide a comfortable hold for the user and ensure that the diamond bur is secured to the handpiece for precise use. diamond burrs
