HT/ST 98mm Dental Zirconia Ceramic Blocks for CAD/CAM Wieland System - 1 Pieces

Feature:
Dental zirconia blocks with plastic ring outside, We choose high quality zirconia powder. Isostatic pressed, ensures all parts have a homogenous density and shrinkage distribution. Discs have the edge groves required for a milling machine. More accurate scaling factor (the persistent and consistency of scaling factor between each batch). Reliable, controllable, reusable production process to make sure the same quality. Easy to cut, no porcelain breakage, less scraps. Every disc has its barcode and scaling factor printed.

Usage:
The dental zirconia blocks is for the creation of crowns, bridges, inlays and veneers of fixed partial denture. Milling dental zirconia block with your CAD/CAM machine and then send the framework into furnace for sintering. The final sintering temperature is 1480 degree Celsius. Control the rate of temperature climbe within 8 degree per minute and make sure the framework is fully cooled down to room temperature before removing it.
