Carbide burs are common tools used in dentistry to perform maintenance on teeth including excavating cavities, drilling old fillings, and finishing preparations for crowns. They are made out of extremely durable materials including steel, steel coated tungsten carbide, diamond coated steel, or tungsten carbide. Tungsten carbide is traditionally preferred as it can be used more times than steel only burs due to the durable nature of this material. While tungsten is typically three times stronger than steel, it is more brittle, but perfectly suitable in high-speed and low pressure dental applications. Additionally, tungsten burs have the ability to hold a sharp edge longer over other bur materials.
Finishing and Trimming Carbides
There are several types of carbide burs that dentists use for different procedures. The most necessary type of dental burs that every dentist should own are the finishing and trimming carbides. This type of dental bur is used to complete the last step in dental procedures by smoothing the walls of teeth and then polishing the composite for a smooth finish.
The most popular finishing and trimming carbides that are currently offered in dentistry supplies are the 12 Blade FB burs. They are constructed out of a single-piece of tungsten carbide and are plated in gold to increase strength and provide anti-microbial benefits for the patient. The solid construction reduces vibrations of the drill and makes the procedure more stable than other dental burs on the market. It also decreases the chances of the tool malfunction which is commonly found in other options for dentistry utensils.
One of the key benefits offered by Metal or Carbide Burs is the improved results versus Diamond Burs. When a dentist is grinding on enamel, a Carbide Bur leaves a generally smoother surface than that produced when using a Diamond Bur, this can substantially reduce time spent polishing the surface post grinding.
One popular brand, specifically NeoBurr, offers a unique neck brazed weld which dramatically improves the longevity of the bur by providing a greater surface area for affixing the bur to the shank. Many dentists report that, while priced more competitively than other brands, NeoBurr brands perform just as well, and often outlast other brands that don’t offer this feature.
How it can help the industry
Dentists that have used the NeoBurr finishing and trimming carbides have noticed the comfortable feel and handling characteristic and that the unique neck offers easy mobility around the inside of the mouth while performing procedures. By offering a variety of shapes for trimming carbides, dental professionals can feel confident that they have the right tool for each patient.
Finishing and trimming carbides have revolutionized the way dentists perform routine maintenance and common dental procedures. They have increased the productivity level of dentist’s offices worldwide because of their smooth performance. By properly cleaning and sterilizing finishing carbides, you can extend the life of the dental bur and decrease the amount spent on dental supplies.
