Method of forming a dental coping from laminated metallic layers in a single heat treatment |
摘要 |
A method for forming a dental coping from a base material composition containing high fusing temperature metal particles and a wax binder and a filler material composition containing low fusing temperature metal particles and a wax binder wherein the two materials are molded over the surface of a die either separately or as a laminate into a shape conforming to the shape of a tooth to be restored and heat treated in a a furnace in a single heat treatment operation from a temperature to cause the high fusing temperature metal particles to form a stable porous structure of high fusing temperature metal to an elevated temperature not to exceed about 1130° C. but preferably between about 1075° C. and 1100° C. so as to melt and densify the low fusing particles into the porous structure.
