DIATECH Z Rex Burs for Crown Preparation Cutting

Why use DIATECH Z-Rex Instruments for zirconia and high-performance ceramics?
The demand for zirconia and high-resistant ceramics restorations has been steadily increasing. However, complications arise, with studies reporting rates ranging from 5% to 16% after 5 years of using these materials. Separating zirconia restorations presents challenges for dental professionals and rotary instruments.
That is where Z-Rex instruments come in. We recommend our green Z-Rex tools for faster and more efficient separation of zirconia and high-performance ceramics. What sets Z-Rex apart? It’s our Enhanced Resilient Bonding. Unlike standard embedding methods, our ERA matrix optimally embeds diamonds. The result? A remarkable 70% increase in hardness (Vickers hardness) compared to conventional bonding, along with enhanced toughness. This minimizes diamond delamination, leading to greater durability and efficiency.
Looking for tips? For cutting zirconia crowns, opt for coarse green instruments during longer cutting periods (greater than 5 min) with larger abrasive particles. Maintain proper water cooling (50ml/min), low contact pressure (1.5N), and adhere to recommended rotation speeds. When it comes to crown cutting, the Red Contra Angle with higher torque is the ideal choice.
With Z-Rex, confidently separate zirconia restorations and experience the difference.
