Ceramic repair without hydrofluoric acid
(2016-01-01)
Purpose: To evaluate the bond strength between composite resin and feldspathic ceramic following repair protocols with and without hydrofluoric acid and aging by thermocycling. Materials and Methods: Forty-eight glass ...
Effect of Different Surface Treatments on the Bond Strength of the Hybrid Ceramic Characterization Layer
(2021-01-01)
Purpose: Using the microshear bond strength (pSBS) test, this study investigated the bond strength between a hybrid ceramic and the extrinsic characterization layer after different ceramic surface treatments. Materials and ...
Effect of ceramic surface treatment on the shear bond strength of a resin cement to different ceramic systems
(2012-09-01)
This study evaluated three surface treatments and their effects on the shear bond strength between a resin cement and one of three ceramics. The ceramic surfaces were evaluated with scanning electron microscopy (SEM ) as ...
Effect of green machining on distortion and surface finishing in advanced ceramic
(2012-11-28)
An alternative for grinding of sintered ceramic is the machining on the green state of the ceramic, which presents easy cutting without the introduction of harmful defects to its mechanical resistance. However, after ...
Surface-layer modification of hydroxyapatite ceramic with acid and heat treatments
(Japanese Society for Dental Materials and DevicesPorto Alegre, 2002)
The purpose of this study was to examine or characterize the surface layer of a calcium phosphate ceramic with a gradual compositional change from alpha-tricalcium phosphate (alpha-TCP) on the surface to hydroxyapatite ...

Biaxial flexural strength and Weilbull characteristics of adhesively luted hybrid and reinforced CAD/CAM materials to dentin: effect of self-etching ceramic primer versus hydrofluoric acid etching
(2020-06-17)
This study evaluated the influence of the surface treatment and aging on the biaxial flexural strength of ceramic materials cemented to a dentin analogue. One hundred twenty disc-shaped specimens were allocated into 12 ...
Flexural strength of a pressable lithium disilicate ceramic: influence of surface treatments
(2013-01-01)
The aim of this paper was to evaluate the influence of different surface treatments on the flexural strength of a pressable lithium disilicate ceramic. Sixteen bars (16x2x4 mm) were made, divided into subgroups (n = 10), ...
The Effect of Surface Treatment on Shear Bond Strength between Y-TZP and Veneer Ceramic: A Systematic Review and Meta-Analysis
(2018-08-01)
Purpose: The objective of this systematic review with meta-analysis was to evaluate surface treatment in yttria-stabilized tetragonal zirconia polycrystal ceramic (Y-TZP) on the shear bond strength (SBS) values between ...
Effect of alternative sonochemical treatment on zirconia surface and bond strength with veneering ceramic
(Elsevier B.V., 2020-02-01)
The morphological characterization of sonochemical treatment on bond strength of Y-TZP/veneer ceramic was evaluated. The surface topography and roughness were analyzed by Confocal Laser Scanning Microscopy, Atomic Force ...
