Preparation of fully-ceramic molded parts (preferably dental molded parts e.g. crowns) comprises contacting ceramic particles into a model (preferably a tooth-technical model); and optionally sintering the obtained ceramic green body

摘要

Preparation of fully-ceramic molded parts (I) (preferably fully-ceramic dental molded parts such as crowns, bridges, etc) comprises contacting ceramic particles into a model (preferably a tooth-technical model); and obtaining ceramic green body, which is optionally sintered after removing from the model, where the model is at least partly (preferably completely) formed as hollow body. Preparation of fully-ceramic molded parts (I) (preferably fully-ceramic dental molded parts such as crowns, bridges or such a thing) comprises contacting ceramic particles into a model (preferably a tooth-technical model), which is made of sinter-shrink of the ceramic particle compensating expandable material; and obtaining ceramic green body, which is optionally sintered after removing from the model, where the model is at least partly (preferably completely) formed as hollow body. Independent claims are also included for: (1) a preparation of a model (preferably a tooth-technical model) for the production of (I) comprising contacting an expandable model material into a negative form (that represents the basic structure for the molded part), distributing the expandable material at the inner wall of the negative form and releasing the obtained model through negative form; and (2) a model (preferably tooth-technical model) for the production of full-ceramic dental molding parts such as crowns, bridges or such a thing) is obtained by the above method.
