摘要：
The invention relates to a method to produce a dental structure with a cavity having a negative form of the structure, which is formed in an investment material, wherein flowable lithium silicate glass ceramic is pressed into the cavity. Thereby a compressive surface stress is created in the ceramic structure through the replacement of lithium ions by alkali ions, in that the model is enriched with alkali compounds and/or the model is covered with a layer of a material containing alkali ions.
