The Best Carbide Burs for Working with Acrylic & Composites
When considering the best type of carbide bur for working with dental acrylic and dental composites, you should consider aspects such as shape, size and blade design. All these elements work together to streamline the process, producing the best results possible for patients and your practice.
Understanding Your Burs
When examining your burs, you already know that diamond burs are a good choice for grinding away at the enamel but remember that they will leave a rough surface.
Carbide burs leave a smoother surface. Created from tungsten carbide, they are around three times stiffer than steel, which makes them the perfect choice to remove large pieces, especially if preparing an area for a filling. Carbides are also a good choice for removing an old filling and for shaping bone.
- Be sure that smaller burs are used in narrow areas to avoid touching surrounding areas.
- Larger burs are better for creating smooth surfaces and reducing the amount of acrylic material.
- Typically, flutes that are deep and wide may be more commonly used to prepare cavities.
Shapes to Consider When Working with Dental Composite and Acrylic
Not sure what type of carbide bur would be best in your situation? Don’t worry, we’ve outlined some of the most common functions for each shape.
According to Inside Dental Assisting magazine, the most popular shapes for carbides are tapered and round because they have the most flexibility and can be used on a wide variety of surfaces. We’ll take a look at the different types of carbide bur shapes and what to consider when purchasing one.
Some of the more common bur shapes and cuts that are most frequently used with dental composite include:
- These can streamline the cutting process. They can section multi-rooted teeth and are also needed if you want to reduce the height of a crown. They cut quickly but often they can cause more vibration.
- A good choice, they may cut slower but are often smoother.
- Inverted cone
- These burs are a good choice for creating undercuts as well as access points. They’re also perfect for cavity preparation.
- This can be another option if you need to create an access point. Like the round shape, they are also used for cavity preparation. For smaller teeth, the pear shape can be useful for splitting roots.
