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.

The invention relates to a coated glass substrate or glass ceramic substrate with resistant, multi-functional surface properties, including a combination of anti-microbial, anti-reflective and anti-fingerprint properties, or a combination of anti-microbial, anti-reflective and anti-fingerprint properties where the substrate is chemically pre-stressed, or a combination of anti-microbial and anti-reflective properties where the substrate is chemically pre-stressed. The coated glass substrate or glass ceramic substrate exhibits a unique combination of functions which are permanently present and do not exert a negative effect on each other.
