A complete guide for choosing dental burs for your clinic

There are a lot of dental burs on the market and this can make it hard to choose the right burs for your dental clinic. However, there are two main ways to choose the right bur – by imagining the shape you want and looking for a bur similar in a catalogue or comparing ISO numbers.

ISO numbers are a system for burs that are classified by number and color and this helps simplify the selection process. The classification system shows the material of the bur, its shape, diameter and coarseness. A lot of manufacturers use acronyms and colours to ease confusion. You can find a shape or ISO designation on the packaging.

Classification of burs

Cutting tools can be made of a wide range of materials. However, the most popular material used to make burs is stainless steel with a diamond-coated end. However, when choosing your dental clinic supplies online, you can be duped by conmen who lie that their burs are coated with diamond when in the real sense they are not.

Diamond burs are fabricated by adhering diamond particles to the steel using galvanic bonding. The metal is then dissolved in a designated electrolytic bath and deposited on a steel shank. It entraps the diamond grit until two-thirds of the particles are completely covered.

In a dental clinic, the exposed diamond chips abrade the structure of the tooth until the desired shape of the dental preparation is achieved. The surface of the tooth and the respective composite material has a rough or sanded appearance with a lot of tiny dust particles that are commonly referred to as a smear layer.

When buying dental burs, it is essential to choose burs from a good dealer. Make sure you read their reviews to ensure their customers are saying nice things about them.
