The Best Burs to Cut Zirconia Crowns

October 11, 2022 blog01

Learn about diamonds and carbides that can make  your life easier when slitting, cutting and adjusting zirconia crowns. 

Zirconia crowns are made of zirconium dioxide, an extremely durable ceramic metal. Zirconia crowns are a popular choice when patients are weighing their dental crown options due to their strength, longevity and the ability to complete the procedure in one visit.

When taken care of properly, zirconia crowns may last a patient’s lifetime. However, sometimes they need to be removed and replaced. Because of their strength, zirconia crowns are exceptionally difficult to manage and cut with conventional diamond instruments. It’s important to choose the best bur to cut zirconia crowns to ensure an easy and fast removal or adjustment.

 Komet USA has a few zirconia cutting burs that are incredibly effective.

ZR Diamond

Komet’s ZR-Diamonds™ contain a densely packed diamond layer with permanently bonded, high-quality diamond particles for optimal durability and an extended service life. ZR-Diamonds™ will get the job done quickly and provide superior results.


The Jackie™ 4ZRS 

The Jackie™ is a ZR-Diamond™ that is uniquely engineered to slit zirconia crowns to easily separate them. Its tapered working end and 4mm length allow this crown cutting bur to create lingual, occlusal and buccal separating joins, which are essential when working to remove adhesive-bonded zirconia crowns.


The 4ZR is a ZR-Diamond™ that is excellent for grinding zirconia crowns. Its cylinder round shape and 8 mm length are unique, enhancing cutting and reducing the labor typically required to cut zirconia crowns.
Tip: To take full advantage of the 4ZR’s shape and size, apply the instrument at an angle of 45 degrees to the zirconia crown.


LD/ZR Intra-Oral Adjustment Kit

If you’re looking for an option that will cover not only cutting zirconia but also adjusting and polishing, then the LD/ZR Intra-Oral Adjustment Kit (LD0707A) is for you.

This kit contains:

The ZR Flash Polishers are interspersed with diamond grit and produce a high-shine finish in just two steps. Pre-polish with the blue polisher, and get a high-shine final polish with the light gray polisher.

No matter which of the above options you choose, you can rest assured knowing that Komet USA’s are the best burs to cut zirconia crowns.
