Diamond burs are rotary tools that use a diamond-tipped bit to grind, smooth and shape materials. They are used in a wide range of applications, including dentistry and jewelry-making. There are a wide variety of shapes, styles and sizes available. The different types of burs can be confusing for new users, so we’ve created this article to help you narrow down your choices and understand what each type is used for.
There are two primary types of dental burs: tungsten carbide and diamond. Both are very useful tools in dentistry, but each have their own strengths and weaknesses. This article will compare and contrast the differences between these two tools so you can decide which one is right for your practice.
Carbide burs are made from a very hard and highly resistant chemical compound. They are extremely durable and are ideal for grinding through hard tissues like teeth and bone. They are often preferred by dentists for preparing teeth for fillings because they cut quickly and efficiently, and they also remove any debris that may interfere with the new filling material.
On the other hand, diamond burs are coated with pieces of industrial diamond. They are a little “gentler” than carbide, and they can be used for tasks such as reshaping the gum line or smoothing down sharp bony edges prior to closing an extraction site. Diamond burs are also able to cut through harder materials that other burs cannot, such as zirconia and porcelain.
Both tungsten carbide and diamond burs come in a wide array of shapes, head angles, blade geometry and grit size. These varying features allow dentists to fine-tune the tool to the specific task at hand. This is particularly important when working with difficult dental materials such as zirconia and lithium disilicate, as they require a more gentle approach to avoid damage or chipping.
Both tungsten carbide and diamond burs are available in a wide array of grit options from ultra fine through super coarse. The choice of grit will determine how aggressively the tool cuts or grinds the surface. The grit selection also plays a role in the longevity of the bur, as softer grits will wear down quicker than harder grits. diamond burrs
