In VITA ENAMIC, the dominant ceramic network structure and the reinforcing polymer network structure are merged fully with one another. Thanks to this dual ceramic-polymer network, the new composite incorporates the benefits of ceramic and composite materials in one outstanding product. Materials science testing shows that as well as offering immense strength, VITA ENAMIC also ensures extraordinary levels of elasticity, even going so far as to include integrated crackprevention. This new class of materials offers significantly less brittleness than a pure dental ceramic as well as abrasion behavior superior to that of conventional composite materials.
As a result, it provides characteristics equivalent to those of natural dentition. Due to its high strength, VITA ENAMIC is extremely resistant to the shear and compressive forces of the stomatognathic system, allowing the material to be used for a variety of applications. Patients consider the oral comfort of VITA ENAMIC restorations to be excellent. In the first phase, VITA ENAMIC will be available in block size EM-14 (12 x 14 x 18 mm), as well as in the shades 0M1, 1M1, 1M2, 2M2 and 3M2 in two degrees of translucency. This innovative hybrid ceramic can be processed using the Sirona CEREC and inLab systems, with construction carried out in the usual fashion. In comparison with pure ceramics, milling can be completed more quickly and with less tool wear.
It is also highly reliable and offers greater precision, improved edge stability and, as a result, finer, more accurate results than are possible with conventional dental ceramics. And with the corresponding polishing set from VITA, the material can also be quickly polished. Glazing using light polymerization is also an option. Characterization can be performed using light-curing stains. The excellent light refraction properties of VITA ENAMIC provide a highly esthetic overall result with a natural play of colors. The hybrid ceramic is already at full strength and can be used directly following milling and does not require further processing.
