Carbide Burs

George Freedman, DDS
Most dentists give very little thought to the tiny tools that are used so often in the clinical practice. Burs may often seem insignificant in size and cost with respect to other commonly used equipment and materials. They do, however, have a major impact on the efficiency of the dental practice and the eventual bottom line.
Burs cut through hard dental tissues and harder dental materials. A sharp, new bur makes tooth preparation virtually effortless for both patient and dentist. Dull, worn burs require more application torque and greater manual effort, cutting more slowly, and causing more patient discomfort. Rapid, efficient burs contribute to the smooth rhythm of the practice and improve the bottom line.
Single-use (disposable) burs are always sharp and cut tooth surfaces rapidly, predictably, and ergonomically, making the dental appointment more comfortable for the patient. Since they are disposed, there is no risk of cross-contamination for patients. Many disposable burs are less expensive in the end.
Reuseable (multiuse) burs are initially more expensive. Each subsequent use decreases the cost per use of the instrument, except that the staff time and material cost of presterilization and sterilization must be added to the equation. In fact, most practitioners find the per-use cost of reusable burs actually higher than that of disposable burs.
While bur prices vary greatly, the cost price is not always the best indicator of its utility in the practice. And the bur experience differs from dentist to dentist. The best method of evaluating a bur’s utility in a particular practice is to test drive it. Every practitioner can determine the specific value and utility of the bur within moments when using it in an actual clinical situation, inside a patient’s mouth. Once a good fit is determined, the practitioner should continue with that product, regardless of cost, until an even better instrument is found. The overall annual cost of all the burs used in a practice is a minimal part of the materials and supplies spent. Good bur choices, however, will positively impact productivity, patient perception and comfort, and dentist ergonomics.
Many dentists make a common supply-stocking mistake: too many bur shapes, sizes, and special-use items that are rarely, if ever, used. The simplest way to overcome this problem is to determine which burs have not been used in the past 12 months. Chances are that if they were not needed in the past year, they will not be needed in the next year either. In short, they are not necessary for the practice.
The practitioner can improve clinical efficiency by limiting the basic bur armamentarium, thereby increasing organization, decreasing costs, and di­minishing practice stress. The best person to determine the burs to be included in the limited armamentarium is the chairside assistant who can readily monitor which cutting instruments are used most often.

SS White Burs

Doctors who used to use 2 or 3 carbides to remove crowns reported using one Great White Gold Series carbide bur to remove 2 to 3 crowns. The faster cutting rate is experienced in amalgam, PFM, and all nonprecious metals, and doctors indicate this saves them 12 hours each year. These burs are ideal for quick removal of amalgam and modern-day composite materials. The burs are also the perfect instruments for any procedure requiring a plunge cut. The Great White 2 can help reduce the number of burs inventoried in any office. For more information, call (800) 535-2877.

Rigid manufacturing tolerances and a unique construction mean you can rely on EDGE CARBIDE BURS to perform, never varying in effectiveness or efficiency and never wearing out before they should. Where most manufacturers use carbide on the cutting portion only, both the cutting portion and the neck of these carbides are constructed of tungsten carbide, resulting in rigidity, concentricity, and cutting control. EDGE CARBIDE BURS are diamond-cut in small batches to maintain the tightest manufacturing tolerances and to ensure quality and consistency are maintained. For more information, call (800) 265-3444.
