Abstract:
The dentine materials of the metal ceramic systems VMK 68 and Biodent as well as the ceramics of all ceramic systems Duceram, Cosmotech, Optec, IPS-Empress and Corum were tested for their leucite content. The structure analysed in the scanning electron microscope showed leucite in the dendritic and idiomorphic form. X-ray diffraction analyses verified the leucite content in metal ceramic systems and ceramics of the nonbonded systems. Comparing the metal ceramic systems with the nonbonded systems, an increase in leucite content was observed in the nonbonded systems.
