Determination of quantitative leucite content in pressable ceramics compared to conventional dental porcelains.
In the present study, the leucite content of two different veneering porcelains and one pressable ceramic have been determined by X-ray diffraction after establishing a standard, using artificial leucite. The results are directly linked to the microstructure and mechanical properties of the materials. The most homogeneous glass-ceramic exhibits the highest relative leucite content and the highest fracture strength.
