Moldable dental material and method |
摘要 |
A moldable dental composition for use in forming or repairing dental restorations composed of a mixture of high- and low-fusing temperature metal particles and a volatile binder, composed substantially or entirely of wax, with the binder having a concentration of between thirty (30%) to eighty percent (80%) by volume of the mixture. The average particle size of the high-fusing metal particles are above one micron, and preferably between four microns and eighty microns in size. The composition is heat treated at a temperature to melt the low-fusing temperature metal particles and to eliminate the binder, leaving a porous metal structure with a void volume above thirty percent (30%). The voids are filled using a filler material of metal or ceramic.
