Investment Materials

Dental investment materials are used to encase the wax designed for the lost wax casting technique. These materials are usually available as a powder that is mixed with water and then used to encase the wax design. These materials solidify and can withstand the heat of the casting furnace to hold the precise shape left behind when the wax is burned out. Different gypsums are designed for use with different dental alloys or other materials, so be sure to select the proper gypsum for the case at hand.

DescriptionPC15 is a fine grained phosphate bonded investment for pressable ceramics. Its creamy consistency pours easily when investing and produces smooth CERA-FINA is a carbon-free phosphate investment developed for professionals who demand a more finely grained investment. It is designed for use with The principal ingredient, CRISTOBALITE, gives high thermal expansion, even at comparatively low temperatures. It is possible to use the same creamy FASTFIRE 15 is a fine grain phosphate investment which requires only a 15 minute benchset before placing molds into a hot oven for rapid burnout. It POLYVEST Refractory Die Material is formulated with a coefficient of thermal expansion to closely match today's newer porcelains. With its controlled
