Research on interfaces between two kinds of veneer porcelains and pre-sintered dental Zirconia framework material

Objective To evaluate the interfaces between two kinds of veneer porcelains and dental Zirconia framework material. Methods X-ray diffraction analysis (XRD) was used to examine the components of two kinds of veneer porcelains after sintering. Veneer porcelains were sintered on the surface of pre-sintered Zirconia ceramic plate under respective procedure. Scanning electron microscope (SEM) was applied to observe the interfaces between two kinds of veneer porcelains and dental Zirconia framework material. Results XRD patterns of veneer porcelains showed that some kinds of crystals such as Nephelina, Anorthoclase and Wollastonite were separated out after sintering. SEM result showed that the interfaces between 3YPSZ and two kinds of veneer porcelains were clear and smooth. Conclusion Further research could be carried out on G-1 and G-2 as veneer porcelains combined with 3YPSZ ceramic framework.
