Translucency of a Dental Porcelain Mixed by Two Ceramic Slurry Methods: A Bayesian Comparison [PDF]

International Journal of Dentistry, 2022
Background. The ceramics industry produces porcelain pastes using a controlled ratio of water and porcelain powder. Two methods are used to produce a dental porcelain paste: one-step mixing or incremental mixing. Objective.

Long-Term Survival Rates of Dental Implants in Patients With Disabilities: A Retrospective Clinical Study With up to 10 Years Follow-Up. [PDF]

J Oral Rehabil
Dental implants in patients with disabilities show high 10‐year survival (98.3%) when supported by principled screening and structured maintenance. This study reveals that while biological failure is rare post‐loading, frequent mechanical complications—predominantly decementation—remain a significant clinical challenge requiring vigilant long‐term ...

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.

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.
