Translucency of Dental Porcelains [PDF]

Journal of Dental Research, 1980
The translucency of comparable shades of five dental porcelains was determined. Both direct transmittance and total transmittance were measured at wavelengths of 400 - 700 nm. For 1 mm of porcelain, the values for direct transmittance were low and averaged 0.13 percent, whereas the values for total transmittance averaged 26.8 percent.

Pre-oxidation of selective-laser-melted titanium dental alloy: effects on surface characteristics and porcelain bonding

Journal of Adhesion Science and Technology, 2021
The heat treatment of dental alloys prior to porcelain application/veneering has been proposed as a way to ensure sufficient oxide scale and to promote the porcelain’s adherence in porcelain-fused-to-metal (PFM) fixed dental prostheses. The present study

Influence of repeated porcelain firing cycles on the microstructure, marginal and internal fit of implant-cemented Co-Cr frameworks. [PDF]

Eur J Oral Sci
Abstract This study investigated the effect of porcelain firing cycles and fabrication techniques on the microstructure, marginal, and internal fit of implant‐cemented cobalt‐chromium alloys (Co‐Cr) frameworks. Two groups of Co‐Cr specimens were prepared: one using selective laser melting (SLM) and the other through the lost wax‐casting technique (C ...

Sintering of Dental Porcelain Enamels [PDF]

Journal of Dental Research, 1976
This study showed the effects of sintering temperature and atmospheric pressure on the density, tensile strength, and microstructure of porcelain enamels. Although the densities of the opaque porcelains were higher, they were weaker than the gingival porcelains.
