Contec 3D-Pro multilayer dental zirconia blocks for dental aesthetic restoration

3D Pro

Zirconia dental material has revolutionized dentistry once again by achieving a natural transition in colour

transparency and intensity in the true sense of the word, enabling another revolution in dental materials. The Zir dental

material also extends the life of the denture with better biocompatibility and no biochemical toxicity

Advantages

1 Layerless natural transition with perfect translucency and strong flflexural strength.

2 Can be individually adapted to the person's teeth.

3 Biocompatible, non-irritating to oral tissues, easy to clean.

4 No blockage to x-rays, no effffect on cranial x-rays, CT, MRI.

5 Resistant to abrasion, corrosion and oxidation.
