Impact of Quantity of Resin, C-factor, and Geometry on Resin Composite Polymerization Shrinkage Stress in Class V Restorations
(Operative Dentistry Inc, 2014-03-01)
Objective: This study evaluated the effect of quantity of resin composite, C-factor, and geometry in Class V restorations on shrinkage stress after bulk fill insertion of resin using two-dimensional finite element ...
Shrinkage Stress, Long-term Adaptation And Bond Strength Of Low-shrinkage Composite Resins
(ELSEVIER SCI LTDOXFORD, 2016)
Shrinkage Stress, Long-term Adaptation And Bond Strength Of Low-shrinkage Composite Resins
(Elsevier Sci LTDOxford, 2016)
A method for calculating the compliance of bonded-interfaces under shrinkage: Validation for Class I cavities
(Elsevier B.V., 2014-08-01)
Objective. The compliance for tooth cavity preparations is not yet fully described in the literature. Thus, the objectives were to present a finite element (FE) method for calculating compliance and to apply this to peak ...
Principales tipo de contracción, efectos sobre el concreto y sus métodos de mitigación
(Escuela Colombiana de Ingeniería Julio Garavito, 2020)
The phenomenon of the shrinkage is one of the main factors that affect the durability of concrete, this is presented as a consequence of the loss of moisture generated in the processes of hydration of cement, in addition ...
A comparative evaluation of polymerization stress data obtained with four different mechanical testing systems
(ELSEVIER SCI LTDOXFORD, 2012)
Objectives. The null hypothesis was that mechanical testing systems used to determine polymerization stress (sigma(pol)) would rank a series of composites similarly. Methods. Two series of composites were tested in the ...
Influence of matrix composition on polymerization stress development of experimental composites
(ELSEVIER SCI LTD, 2010)
Objective. Stress development at the tooth/restoration interface is one of the most important reasons for failure of adhesive restorations. The aim of this study was to evaluate the influence of BisGMA/TEGDMA (B/T) and ...
Influence of the curing method on the post-polymerization shrinkage stress of a composite resin
