Technology is advancing in the investigation of the ceramic materials used as part of majority in their composition and combined to reach the optimal goal of maintaining the positive qualities of ceramics such as aesthetics and resistance, and improve their weaknesses (abrasiveness and fragility).

The DRM (Diamond Crown) has in its composition to 80% linked by a ceramic matrix 20% PEX (Epoxine Phenolic Monomer). The fact nanoceramic use of different shapes and sizes PEX joined by an array of physical and biological characteristics comparable to natural tooth and the gold, makes us a material with the appearance of a ceramic. In fact it could be defined as a ceramic microelastica with the ability to work as a composite both laboratory and clinical (linear shrinkage of 0.2% versus the ceramic is 17%).

Policerámica name is used to differentiate the composites which are basically made of a resin-based matrix and Bis-GMA or UDMA and an inorganic filler such as silicon dioxide, which have nothing to do with the characteristics of PEX. Read the rest of this entry »
