The phosphate bonded investment materials are used for casting porcelain-fused-to-metal castings, because the alloys used in these constructions are melted at higher temperatures than the traditional gold alloys. The silicate bonded investment materials are primarily used for casting partial denture frameworks in base metal alloys.5 Investments and Refractory Dies Pocket DentistryJan 01, 2015The investment mould used for casting alloys and some castable ceramics needs to be constructed from a material which retains its integrity at the casting temperature. Unmodified dental plasters or stones are not suitable for this purpose. A group of materials which are closely related to the investment materials are the refractory die materials.

The effects of different types of investments on the alpha dental casting investment materials

CONCLUSIONS The type of investment affects the microstructure and microhardness of the alpha-case layer of titanium castings. Based on the thickness of the surface reaction layer and the surface microhardness of titanium castings, MgO-based investment materials may be the best choice for casting these materials.
