Important Technical Tips

When casting the male burn out pattern, ensure that the alloy has a minimum Vikers hardness of 300
Use a surveyor rod when positioning 2 or more Micro 2 GM
Using high fusing wax, carefully seal the space between the male/female assembled attachment parts and the model. This will prevent any acrylic from penetrating the housing
Before processing the acrylic denture, it is extremely advisable to coal all parts affixed to the model with a tick and supple varnish. (Varnish available)
