The Best Finishing Burs for Your Practice
You’re facing two very challenging tasks. First is the restoration of your patients’ teeth. This may mean making a crown or simply filling a cavity. The second challenge is the effort to make the tooth look natural, providing a smooth contour and refined polish. Properly finishing a tooth is where advanced dental science mixes with crafted artistry to create a surface that is as close to the original tooth as possible.
This is why fine grit burs and finishing carbides are some of the most instrumental parts of your bur set. It’s vital that no excess material goes beyond the cavity or overhangs. It also has to properly align with other teeth. Properly finishing teeth also means that there is less risk of staining, and it helps keep plaque from gathering on the surface of your restorations.
Getting a stellar result means using the right tools, and we want to review with you some vital finishing bur bits to have in your bur set.
What type of finishing bur or bits should you use?
Following are some things you should keep in mind when deciding what type of finishing dental diamond bur set to purchase for your practice.
According to the book Aesthetic Dentistry comfort is the main factor in selecting a bur. This means a better experience for your patient and yourself. As we discussed in an earlier blog post, patient satisfaction creates a more pleasant work environment for all who are involved.
Dental Bits & Burs to Avoid
You should not use non-flexible strips and abrasive discs because they can flatten the tooth’s contours. These anatomical contours are essential in creating the natural look your patient needs. You should also avoid coarser diamond burs as well as carbides with more than 12 flutes. These bur bits can cause damage to the outer restoration layer.
Use the Most Appropriate Bur Shapes
Needle-shaped, fluted tungsten carbide burs are a good choice, as long as they are 8 to 12 fluted. These help recreate the peaks and valleys that are seen in natural teeth. Pointed burs can also help when you’re attempting to finish areas that are located in the margins. It’s important to always use lighter pressure and a large amount of coolant.
What should you look for in a good finishing bur?
Dental bur assortment sets don’t always get the attention they deserve. After all, there are several more high-dollar items in use for your dental practice, and these bits may seem minor when compared to the investment in materials such as digital X-rays, sterilization equipment and even dental chairs.
But an efficient finishing bur is a benefit to both your practice and the bottom line. Don’t fall for the “false economy” of burs that are inexpensive but don’t last long. Look for carbide burs that have less vibration and “chatter” in order to help you shape bone. Some of the less coarse diamond burs could be a good choice, particularly for extreme precision and polishing.
Several Important Factors of Selecting a Dental Bur Set
There is a dizzying array of various dental bur sets you can select, so how can you tell which is the right one for you? We’ve outlined a few important points you should consider.
First, examine the primary focus of your practice. Do you concentrate more on orthodontics or does your office specialize in endodontics? You should gear your tools to the procedures you perform the most. For an example, crosscut burs will cut faster, while those used for preparing teeth for a restoration or filling will cut wider and deeper.
Second, examine the shape you need. It’s important to focus on the shapes you use most—each shape can be used for certain procedures, and the cut of the bur can often influence how much the handpiece vibrates. This can make a big difference in precision.
Third, look at the type of material that will work best. As we’ve discussed in this article, coarse diamonds may not be the best choice for finishing, but some of the smoother varieties of diamonds may be effective, especially for polishing. For more information, check out this useful article that will help you determine if diamond or carbide burs will be the best choice for you.
