In vivo low thermal degradation of monolithic zirconia restorations

Dental Materials, 2017
A 5-year clinical study was designed to evaluate the in vivo low thermal degradation (LTD) of zirconia monolithic restorations on implants and natural teeth. Additionally, general behavior of restorations and material wear were studied. This work focuses on ex vivo analysis of zirconia phase transformation and on the influence of glaze protection and ...

Monolithic zirconia gels from metal—organic solutions

Journal of Materials Science Letters, 1986
It has recently been shown by Ganguli and Kundu [1] that amorphous and transparent coatings of pure ZrO 2 could be prepared by controlled hydrolysis of zirconium propoxide and subsequent polymerization by using a non-polar solvent like cyclohexane instead of the usual alcoholic solvents employed for preparing coatings and monoliths [2-7]. The non-polar,

Optical properties of pre-colored dental monolithic zirconia ceramics

Journal of Dentistry, 2016
The purposes of this study were to evaluate the optical properties of recently marketed pre-colored monolithic zirconia ceramics and to compare with those of veneered zirconia and lithium disilicate glass ceramics.Various shades of pre-colored monolithic zirconia, veneered zirconia, and lithium disilicate glass ceramic specimens were tested (17.0×17.0 ...

Translucency of IPS e.max and cubic zirconia monolithic crowns

The Journal of Prosthetic Dentistry, 2018
Although several monolithic zirconia ceramics have recently been introduced, the need for improved optical properties remains. The newest cubic-zirconia has been claimed to have optimal translucency characteristics for esthetic restorations.This in vitro study evaluated the optical properties of novel cubic ultratranslucent (UT) and supertranslucent ...

Antagonist wear of monolithic zirconia crowns after 2 years

Clinical Oral Investigations, 2016
The aim of this study was to evaluate the amount of wear on the antagonist occlusal surfaces of clinically placed monolithic zirconia premolar and molar crowns (LAVA Plus, 3M ESPE).Fourteen in situ monolithic zirconia crowns and their opposing antagonists (n = 26) are the subject of an ongoing clinical trial and have been clinically examined at ...
