diamond burrs with metallic are used in dental procedures for cutting and grinding hard tissues, including enamel and bone. They are also useful for carving stone in lapidary and jewelry making. The shape of the head and grit size determines what type of procedure it can be used in.
These sintered diamond burrs have a strong metallic binder to make them durable and long-lasting. They have colored stripes on the shank that indicate the grit. They are categorized as black (super coarse), green (coarse), blue (medium), red (fine), and yellow (ultra fine). These colors are used to distinguish the different types of diamond burs.
The different grits allow them to perform various tasks in dental procedures. For example, coarse-grit diamond burs can be used to remove hard tissue and bone while fine-grit ones can be used for finishing and shaping teeth. The use of these burs allows dentists to finish a tooth in less time than traditional metal files and reduces the patient’s exposure under anesthesia.
Using a diamond bur for polishing is another way that dentists can increase the speed of their work and decrease patients’ exposure under anesthesia. This is because a diamond bur cuts faster and smoother than a file or abrasive wheels. It is also easier on the gums and tissues of the mouth than other abrasive devices.
Sintered diamond burs have a metallic binder that increases their durability and longevity, which makes them a good option for those who need to use their tools frequently. They are available in single-use and multi-use options. Single-use burs are sterilized and can be used for each new patient, while the multi-use variety is designed to be re-used for multiple procedures.
Another benefit of using a diamond bur is that it does not heat up as quickly as a metal file. This is important in preventing the melting of the tooth or abrasions on the surrounding soft tissue. It is also safer to use than a metal file because it does not produce as much friction or heat.
The study also found that using a diamond bur on zirconia and other hard materials such as lithium disilicate and CoCr has a positive effect on surface roughness. It can also help increase the machinability of these materials. This is because a metal-bonded diamond bur can cut through these hard materials more easily than other abrasive devices. It can also be used to reduce vibration during the preparation of a tooth. This is because a metal-bonded zirconia/CoCr diamond bur does not produce as much friction as a standard steel or tungsten carbide diamond bur. This may be because the abrasive particles in a diamond bur are coated on a ceramic/CoCr substrate, which reduces vibration and temperature. This is especially true for coarse-grit diamond burs, which are more likely to generate friction than a finer-grit one.
