Filling system for root canals that combines two products in one: sealer and gutta-percha in powder form with a particle size of less than 30µm. Flowable, non-heated gutta-percha that does not shrink but expands slightly by 0.2%. Good adhesion to gutta-percha points and dentine walls. Combination of expansion and adhesion creates an excellent seal. Thixotropic: the viscosity diminishes under pressure, allowing it to flow into the smallest canals during placement of the master point and optional auxiliary points, for a three-dimensional obturation without condensation. Solubility of virtually 0, dimensionally stable and impervious root canal fillings. Extremely biocompatible. Contains micro-silver that provides optimum protection against reinfection of the root canal. The chemical form and concentration of the silver does not lead to any corrosion or discolouration under clinical conditions.
