Bending strength

The average biaxial bending strength of crystallized YPDENTAL glass ceramics is 637Mpa,which is higher than the standard strength value set by ISO 6872:2008 dental ceramic material. Its superior strength can be used to make three-unit bridge for the molar teeth.

Applications

Simple and fast process, convenient treatment for patients
Rapid crystallization, the best choice for immediate restoration.
High strength, suitable for various cases.
High transparency, matching the natural color of the teeth.
