GC Initial MC Dentin D-C3 GC Initial MC is a porcelain for the production of crown / bridge on conventional dental alloys with a CTE in the range 13.8 - 14.9 (25 -500 ° C) Initial MC can be used on alloys that contain silver, high-grade alloys, gold-reduced and palladium-based alloys plus base. The porcelain can also be used for sintering techniques in the production of inlays, onlays and veneers on fuel gypsum. Initial MC is part of a larger system that makes it possible to build a crown / bridge on several types of substructures with the same selection of porcelain masses and the same layer technique.
