Contraction stress related to composite inorganic content
(ELSEVIER SCI LTD, 2010)
Objectives. The role of inorganic content on physical properties of resin composites is well known. However, its influence on polymerization stress development has not been established. The aim of this investigation was ...
Alternative photoinitiator system reduces the rate of stress development without compromising the final properties of the dental composite
(Elsevier Sci LtdOxfordInglaterra, 2009)
Factors Affecting Photopolymerization Stress in Dental Composites
(INT AMER ASSOC DENTAL RESEARCHI A D R/A A D R, 2008)
Polymerization stress development results from the complex interplay of volumetric shrinkage, reaction kinetics, and viscoelastic properties. The objective of this study was to examine the relationships among volumetric ...
Polymerization kinetics and polymerization stress in resin composites after accelerated aging as a function of the expiration date
(Elsevier B. V., 2015)
To determine the effect of material condition (new, aged, and expired) on the polymerization kinetics and polymerization stress of different classifications of dental composites. Specimens were obtained according to the ...
Effect of light-curing units and activation mode on polymerization shrinkage and shrinkage stress of composite resins
(Faculdade De Odontologia De Bauru - USP, 2008)
The aim of this study was to evaluate the polymerization shrinkage and shrinkage stress of composites polymerized with a LED and a quartz tungsten halogen (QTH) light sources. The LED was used in a conventional mode (CM) ...
Polymerization stress, shrinkage and elastic modulus of current low-shrinkage restorative composites
(ELSEVIER SCI LTD, 2010)
Objective. To compare currently available low-shrinkage composites with others regarding polymerization stress, volumetric shrinkage (total and post-gel), shrinkage rate and elastic modulus. Methods. Seven BisGMA-based ...
Contraction stress determinants in dimethacrylate composites
(INT AMER ASSOC DENTAL RESEARCHI A D R/A A D R, 2008)
The influence of composite organic content on polymerization stress development remains unclear. It was hypothesized that stress was directly related to differences in degree of conversion, volumetric shrinkage, elastic ...
Association of photoactivation methods and low modulus liners on marginal adaptation of composite restorations
(Taylor & Francis AsOsloNoruega, 2004)
Influence of filling techniques on shrinkage stress in dental composite restorations
(Elsevier TaiwanTaipeiTaiwan, 2013)
Polymerization Shrinkage and Push-out Bond Strength of Different Composite Resins for Sealing the Screw-access Hole on Implant-supported Crowns
(2020-01-01)
Purpose: To evaluate the effect of composite resin polymerization shrinkage stress on the stress distribution in the implant-supported crown-access hole, and on the bond strength between the ceramic and composite resin. ...
