Completely biocompatible to guarantee a perfect integration in harmony with the human body without releasing any toxic substances. High stability resin matrix and absence of nanoparticles in the powders generated by abrasion phenomenon that could be absorbed by the body. The UDMA and TCDDMDMA innovative formula is Bis-GMA free, monomer that can liberate Bisphenol-A (BPA), an organic compound that exhibits estrogenic properties in human body causing health problems.
