Verfahren zur Erzeugung einer Zahnrestauration sowie eine Substruktur dafür.

摘要

A method of making a substructure for a dental restoration which comprises a substructure of a dental metal and a fired on coating of a dental ceramics, which method comprises applying a powder-form mixture of a dental metal powder (1) and a thermoplastic polymeric material having a melting point above 50 DEG C, in the shape of the dental restoration to be made, to a porous refractory model (4), by means of a heated instrument, heating the assembly so obtained to a temperature at which the thermoplastic polymeric material liquefies and is sucked from the coating into the model (4), followed by raising the temperature of the assembly to a temperature at which the thermoplastic polymeric material disappears, and raising the temperature further to a sintering temperature at which the dental metal powder (1) is sintered into a solid metal mass. The substructure so formed can be provided with a fired on coating of dental ceramics.
