When it comes to dental burs, they come in different shapes, sizes, and varieties, each with its own set of benefits. Some people are better at particular things, but making the right decisions is critical to your practice’s economic success. We’ve looked at five different kinds of dental operative burs and given information to assist you to choose the correct one for your dental or orthodontic practice.
These are used with high-speed handpieces. Because diamond is one of the toughest known materials, these burs are routinely used to cut through zirconia or grind porcelain. Diamond burs are available in a variety of shapes and grits, ranging from ultra-fine to super coarse. Diamond burs are very effective when cutting away porcelain restorative material. They’re used for crown and veneer procedures because they’re developed to minimize tooth structure. They are of excellent quality and provide excellent accuracy, allowing for a quick and smooth cut.
When to use: Cutting through the porcelain, polishing.
These burs are made of Tungsten carbide. It is three times stiffer than steel. Because it is made of such a durable substance, it can keep its sharpness for a long time, making it an excellent cutting tool. Carbide burs come in a variety of shapes, similar to diamond burs. Because of the incisions formed in the bur’s head, they are effective cutting devices with minimum debris buildup. Carbide burs are easier to work with when it comes to removing metal-based restorations, as well as trimming and polishing macro-filled and hybrid composites
When to use: These are used to prepare teeth for dental fillings and to shape bones before other treatments. They can also be used to remove old fillings.
Steel burs are a low-cost method of cavity preparation and dentine removal. These types of burs are soft, more flexible, and more robust to chipping and breaking than carbide burs, but they blunt more quickly due to their flexibility.
When to use: Steel burs are used for cavity preparation and dentine removal.
Ceramic dental burs are used to modify acrylic parts used in dental operations. Since they do not conduct heat, they do not heat up like other dental burs. It’s also a fantastic choice for adjusting thermoplastics. With ceramic burs, there is a low chance of burns.
When to use: These are used to adjust acrylic pieces in dental operations.
Cross-cut tapered fissure
Because cross-cut burs have more cuts in the blade, they give more efficient cutting action with less debris buildup. Tapered crosscut fissure burs are used for sectioning multi-rooted teeth and reducing crown height.
