Z-Rex Diamond Burs

The Perfect Bur for Zirconia and Ceramic Crown Preps.

High performance ceramics, like zirconia, are on the rise as crown and bridge materials. Their ability to mimic the reflective quality of original teeth,  high resistance to temperature changes and ability to resist wear is unmatched.  However, the material is difficult to manipulate with conventional instruments.

DIATECH Z-Rex diamond burs are the solution! They make it easy to adjust, trepan or remove ceramic restorations. The unique synthetic diamond mixture offers an exceptional combination of durability and efficiency.

DIATECH Z-Rex burs are offered in two grits:

  • Medium Grit: reduces the likelihood of micro fractures
  • Coarse Grit: for increased, yet even, crown cutting efficiency

Ideal for:

  • Endo Access
  • Crown Adjustment
  • Crown Cutting

Individually packaged in blisters.

Diamond Burs for Zirconia and High Performance Ceramic Crowns

Which Dental Burs are the Best for Adjusting Zirconia Crowns?

It’s a fact: More and more of your patients will have high-performance materials like zirconia for their crown and bridge material.

This creates a unique challenge: Conventional instruments frequently don’t work with this material. Therefore, you need to be sure you have the perfect set of zirconia-cutting dental burs. These burs must be strong enough to be effective while minimizing the risk of microfractures. 

Adjusting zirconia crowns requires not only a skilled hand but also the right tools. Standard instrumentation often falls short in this regard. To achieve precise results, you need the best zirconia-cutting dental burs.

We’ll explore the techniques involved with crown cutting and zirconia, as well as how Diatech’s Z-Rex diamond burs are the perfect solution for your practice.

Top Features of the Best Zirconia Cutting Burs

When it comes to zirconia cutting, our Z-Rex diamonds offer the best solution. These burs provide the necessary crown-cutting efficiency to adjust, trepan, or remove ceramic restorations while reducing the likelihood of microfractures. Here are some notable features of Z-Rex burs:

  • Revolutionary ERA Bonding: Our burs utilize ERA bonding, which significantly reduces delamination of diamonds. ERA bonding improves the embedding of diamonds, resulting in increased hardness by 70% compared to conventional bonding (according to Vickers hardness scale).
  • Exceptional Durability and Efficiency: Z-Rex burs combine durability and efficiency, ensuring a shortened procedure time that maximizes practice profitability.
  • Individually Packaged for Convenience: Each bur is individually packed in blisters for added convenience and easy tracking.

Removing and adjusting zirconia crowns can be challenging, but Diatech’s Z-Rex diamonds offer durability and efficiency for this task. Test results from King’s College in London have shown that Z-Rex burs, with their revolutionary ERA bonding, significantly reduce diamond delamination. 

Zirconia Dental Burs vs. Gold Diamond Burs: Understanding the Differences

When it comes to dental burs, both zirconia and gold diamond burs serve specific purposes and have unique characteristics. Here are the key differences between these two types of dental burs:

  • Material Composition

    Zirconia Dental Burs:

    Zirconia burs are typically made from a zirconium oxide compound. This material is known for its high strength, durability, and ability to cut through tough materials.

    Gold Diamond Burs:

    Gold diamond burs feature a metal shank with a diamond coating on the working surface. The gold-plated shank provides additional strength and stability, while the diamond coating ensures efficient cutting performance.

The Right Dental Tool Depends Upon the Situation

It’s important to note that the selection of the appropriate dental bur depends on the specific clinical situation, the material being worked on, and the desired outcome. Dental professionals should consider the material properties, cutting efficiency, and applicability when choosing between zirconia and gold diamond burs for specific dental procedures.

Why Is It Popular to Use Zirconia for Dental Restorations?

Zirconia restorations have gained popularity for several reasons. We’ve outlined a few below:

  • Strength and Durability: Zirconia is known for its exceptional strength and durability. It is highly resistant to fractures, making it an ideal material for dental restorations that need to withstand the forces of biting and chewing.
  • Aesthetics: Zirconia restorations closely resemble the natural appearance of teeth. Patients can enjoy a beautiful, natural-looking smile with zirconia restorations.
  • Biocompatibility: Zirconia is biocompatible, meaning it is hypoallergenic and does not trigger sensitivities or allergies in most individuals. 
  • Versatility: Zirconia can be used for a wide range of dental restorations, including crowns, bridges, implant-supported restorations, and even veneers. Its versatility allows dental professionals to address various clinical situations and provide comprehensive treatment options to patients.
  • Long-Term Esthetic Stability: Zirconia restorations offer excellent color stability over time. Unlike other materials that may discolor or fade with age, zirconia maintains its natural-looking appearance, providing long-term esthetic stability and patient satisfaction.

With their numerous advantages, zirconia restorations provide patients with reliable, long-lasting, and aesthetically pleasing dental solutions.

How to Cut a Zirconia Crown

Crown-cutting for zirconia crowns is a challenging and exacting process that demands precision. To achieve quality results, it’s essential to use a bur that provides optimal performance. Here are some key points to consider:

  • Diamond Bur Selection: Choose a diamond bur with a densely packed, bonded diamond layer. This ensures efficient cutting while keeping the restoration surface convex. Football, straight, or egg-shaped burs are often suitable for this purpose.
  • Maintaining a Light Touch: Excess pressure can lead to microscopic cracks in zirconia. Therefore, it’s crucial to apply a light touch during the cutting process.
  • Importance of Polishing: Zirconia does not naturally smooth out over time. Therefore, polishing before cementation is vital, and using the best zirconia-polishing dental burs ensures optimal results.
