Neural tool condition estimation in the grinding of advanced ceramics
(2015-01-01)
Ceramic parts are increasingly replacing metal parts due to their excellent physical, chemical and mechanical properties, however they also make them difficult to manufacture by traditional machining methods. The developments ...
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 ...
Fatigue failure load of two resin-bonded zirconia-reinforced lithium silicate glass-ceramics: Effect of ceramic thickness
(2018-06-01)
Objectives: To evaluate the effect of ceramic thickness on the fatigue failure load of two zirconia-reinforced lithium silicate (ZLS) glass-ceramics, adhesively cemented to a dentin analogue material. Methods: Disc-shaped ...
Characterization of ceramic powders used in the inCeram systems to fixed dental Prosthesis
(ABM, ABC, ABPol, 2007-03-01)
InCeram (Vita Zahnfabrik- Germany) is known as a high strength ceramic being used for core crowns and for fixed partial denture frameworks. InCeram system consists of slip-casting technique which is used for to build the ...
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 ...
The use of FT-IR spectroscopy and SEM/EDS characterization of slips and pigments to determine the provenances of archaeological ceramics: The case of Guanacaste ceramics (Costa Rica)
(2021-03)
In this paper, the red and black pigments and slips of 63 Guanacaste ceramics were analyzed by Scanning Electronic Microscopy and infrared spectroscopy. All the pigment layers were made by dilution of a pure pigment in the ...
Effect of mechanical cycling on the flexural strength of densely sintered ceramics
(Elsevier B.V., 2014)
Factors to Achieve Aesthetics in All-Ceramic Restorations
(Lippincott Williams & Wilkins, 2010-11-01)
The demand for aesthetic restorations has increased during the last years. Dental ceramics are a successful alternative for some cases because of aesthetics and biocompatibility. Therefore, the aim of this literature review ...
