KZR-CAD HR2

Features

The Evolution of Ceramics Cluster Filler

The particle density of the ceramics cluster filler used for KZR-CAD HR 2 is controlled to be 1 to 20 μm and have almost the same density as the matrix area shown in the picture on the right. As a result, the surface is so homogenized that the filler cannot be recognized even under 1,000 magnification. While it maintains outstanding strength and durability, it also succeeds in dramatically improving polishability and abrasion resistance.

Outstanding Strength and Durability

KZR-CAD HR 2 has maintained high flexural strength of over 250 MPa and it has the same excellent durability as KZR-CAD HR, even after thermal cycle testing (5,000 times at 4-60°C, equivalent to about 1 year and a half *2).
*2) Assuming 10 thermal changes a day.

Long-term Sustained Release of Fluoride

KZR-CAD HR 2 continuously releases fluoride ion securely, and stably maintains its strength by optimization of the surface-treatment conditions of fluoride ion release filler.

High Abrasion Resistance

KZR-CAD HR 2 is less likely to be worn away. At the same time, it is less likely to damage the opposing tooth, and the problems caused by losing occlusion balance are rendered less likely to occur by the way the product keeps a moderate level of abrasiveness.

Excellent Processability

Polisher: C&B DIAMOND POLISHER, C&B NANO DIAMOND POLISHER, manufactured by Yamakin. The data below has been gathered following Yamakin’s set procedures, and values may vary depending on the conditions prevailing. The figure shows data for a case in which an S -size block is used for a premolar.

KZR-CAD HR 2 is the new block for CAD/CAM. It has excellent processability and polishability, while maintaining outstanding strength and durability. This is achieved by the evolution of our ceramics cluster filler, as well as by our homogenization technology.

Excellent Discoloring Resistance and Staining Resistance

Since KZR-CAD HR 2 is polymerized to a high degree by heat processing, its excellent staining resistance is confirmed; it is hard to discolor in the long term and long-term endurance of aesthetic quality can be expected. This has been confirmed by studies comparing extracted teeth of bovine(Enamel and Dentine).
