Effect of occlusal anatomy of CAD/CAM feldspathic posterior crowns in the stress concentration and fracture load
(2021-01-01)
Objectives: This study evaluated the effect of restoration occlusal design on the maximum fracture load and stress distribution of a feldspathic ceramic crown. Materials and Methods: Twenty dentin analogues were used to ...
Aspiration of the dental crown in an elderly patient
(2021-08-01)
The aspiration of objects and foreign bodies requires quick and systematic care. During emergent orotracheal intubation, accidental dental crown release can cause a threat to the patient's life. This paper aimed to report ...
In Vitro Study of Fracture Load and Fracture Pattern of Ceramic Crowns: A Finite Element and Fractography Analysis
(Wiley-Blackwell, 2011-08-01)
Purpose: This in vitro study investigated the null hypothesis that metal-free crowns induce fracture loads and mechanical behavior similar to metal ceramic systems and to study the fracture pattern of ceramic crowns under ...

Crown fracture: Failure load, stress distribution, and fractographic analysis
(Elsevier B.V., 2015-09-01)
Statement of problem. The outcomes from load-to-failure tests may not be applicable to clinical situations. Purpose. The purpose of this study was to critically evaluate the efficacy of load-to-failure tests in the ...
Fracture Load And Phase Transformation Of Monolithic Zirconia Crowns Submitted To Different Aging Protocols
(Operative Dentistry INCIndianapolis, 2016)
Evaluation of tensile tetention of Y-TZP crowns after long-term aging: Effect of the core substrate and crown surface conditioning
(Operative Dentistry Inc, 2014-11-01)
This study evaluated the effect of the core substrate type (dentin and composite resin) on the retention of crowns made of yttrium oxide stabilized tetragonal zirconia polycrystal (Y-TZP), submitted to three inner surface ...
Fatigue life and failure modes of crowns systems with a modified framework design
(ELSEVIER SCI LTD, 2010)
Objectives: To evaluate the effect of framework design on the fatigue life and failure modes of metal ceramic (MC, Ni-Cr alloy core, VMK 95 porcelain veneer), glass-infiltrated alumina (ICA, In-Ceram Alumina/VM7), and ...
