Mechanical and physical properties of silorane and methacrylate-based composites

Journal of Dentistry, 2013
This study measured the degree of conversion (DC), sorption, solubility and microhardness of methacrylate (Filtek Z250 and Filtek Z350XT) and silorane-based composites (Filtek P90).DC was measured using near infrared spectroscopy immediately and 24h after the photoactivation. Sorption and solubility measurements were performed after 24h, 4 weeks and 12

Three‐Year Clinical Evaluation of a Silorane Composite Resin

Journal of Esthetic and Restorative Dentistry, 2013
AbstractStatement of ProblemComposite resins are still outperformed by amalgams in the clinical practice with secondary caries and fractures being their most common failures. A material that suffers less polymerization shrinkage might improve the clinical performance of composite resins.PurposeTo evaluate the clinical performance of a low‐shrink ...

Model of Silorane Composite for Bone Stabilization Application

ASME 2010 Summer Bioengineering Conference, Parts A and B, 2010
Improvements in body armor and battlefield medical care have resulted in an increase in survival rates but also an increase in survivable battlefield extremity injuries (Covey 2002; Covey 2006; Owens, Kragh et al. 2007). It is well known that these traumatic extremity injuries require adequate stabilization to achieve an optimal healing outcome ...

Microtomographic evaluation of the bone–cell interactions with a silorane‐based composite

Microscopy Research and Technique, 2012
AbstractThe low‐shrink Silorane‐based composite could bond effectively to bone and showed the potential be used as a bone cement. Bone organ culture maintains the anatomical order, natural cell‐to‐cell and cell‐to‐matrix relationship. The purpose of this study was to evaluate the responses of bone cells to a Silorane‐based composite which was compared ...

Degree of conversion and Knoop microhardness of a silorane composite

Dental Materials, 2014
Purpose: To evaluate the relationship between degree of conversion and microhardness of a composite based on silorane monomers (Filtek P90-3M ESPE). Methods andmaterials: The specimens (n=10/gp, cylindrical 5mm× 2mm, light-cured 1100mW/cm2) were divided into 5 groups according to the energy amount obtained by the variation in the irradiation time (8 ...

Silorane adhesive system: a case report.

Journal (Canadian Dental Association), 2015
Silorane-based composite resin requires a specific adhesive system: a 2-step self-etching adhesive. Clinical protocols are well established and are based on the principles of adhesion to mineralized dental tissues. In this paper, we present a clinical application of the silorane adhesive system in a class-II restoration using silorane-based composite ...

Mutagenic activity of structurally related oxiranes and siloranes in Salmonella typhimurium

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2002
Ring-opening molecules like oxiranes (epoxides) maybe suitable for the development of non-shrinking dental composite materials. Since oxiranes are reactive molecules, they can cause adverse biological effects in living organisms. The introduction of siloranes, a merger of silane and oxirane, may solve this problem. Here, new oxiranes and siloranes were

Low Shrinkage Silorane Composites.

Northwest dentistry, 2019
Polymerization shrinkage of methacrylate composites utilizing bisphenol-A glycidal methacylate or urethane dimethacrylate has typically been about 3-3.5% by volume. Though adjustments have been made to filler loading, filler size, filler particle distribution, and improved silanization, the polymerization contraction still creates some significant ...

Effect of preheating and shade on surface microhardness of silorane‐based composites

Journal of Investigative and Clinical Dentistry, 2016
AbstractAimThe aim of the present study was to evaluate the effect of preheating and shade on the surface microhardness of silorane‐based composites.MethodsThree shades of two different types of composites were evaluated: a silorane‐based composite and a methacrylate‐based composite.

Bond strengths of a silorane composite to various substrates.

American journal of dentistry, 2011
To evaluate the shear bond strength (SBS) of a novel low-shrink posterior resin composite (Filtek LS) to various substrates.The dedicated LS System Adhesive was used to bond Filtek LS to bovine dentin, ground bovine enamel, resin-modified glass-ionomer liner (Vitrebond Plus), conventional glass-ionomer restorative material (Fuji IX GP Extra), and ...
