Process for the preparation of a dental prosthesis by slight solid phase fritting of a metal oxide based infrastructure

摘要

A method for manufacturing a dental prosthesis from a shaped, slightly solid phase fritted metal oxide infrastructure whose pores are impregnated with a glass by molding a tooth model from a linearly expanding molding mass and contacting the model with a slip of metal oxide particles which particles are agglomerated onto the model. The agglomerated metal oxide particles forming an infrastructure which is shaped and baked to effect dehydration and withdrawal of the model from the infrastructure before the fritting and glass impregnation of the infrastructure.
