Fracture Behavior of Dental Composite Resins

Bio-Medical Materials and Engineering, 1991
Fracture toughness (KIC) critical stress intensity factor, and bending strength of 3 types of commercially available dental composite resins (macrofilled. hybrid and microfilled type) were determined using three point bend specimens. Acoustic Emission (AE), which is the generation of elastic wave due to the release of energy from the localized sources ...

Nanomechanical properties of dental resin-composites

Dental Materials, 2012
To determine by nanoindentation the hardness and elastic modulus of resin-composites, including a series with systematically varied filler loading, plus other representative materials that fall into the categories of flowable, bulk-fill and conventional nano-hybrid types.Ten dental resin-composites: three flowable, three bulk-fill and four conventional

Repair of dental resin-based composites

Clinical Oral Investigations, 2012
The study analyzed the reparability and compatibility of light-curing resin-based composites (RBCs) of the categories "microhybrid," "nanohybrid," and "packable."Six RBCs with different matrix and filler formulation--purely methacrylate-based composites (MBCs), ormocer-based composites (OBCs), and silorane-based composites (SBCs)--were used for the ...

Antibacterial dental resin composites

Reactive and Functional Polymers, 2014
Abstract Resin composite materials exhibit good esthetic properties and strength, making them the most commonly used materials for restoring hard tissue, i.e., enamel and dentin. In the last 30 years these restorative materials have been widely used for both anterior and posterior restorations.

The ultrastructure of a dental composite resin

Proceedings, annual meeting, Electron Microscopy Society of America, 1988
Methacrylate has been used as a resin with exceptional cutting quality for electron microscopy, but suffers from problems of stability in the electron beam. On the other hand, one of the areas it is used is as a synthetic resin where it is increasingly becoming a factor in the restoration of missing tooth structure in dentistry.

Composite resins as a dental restorative material

Journal of Biomedical Materials Research, 1971
AbstractThe objective of this study was to assess the finished surfaces of various dental composite resin restorative materials using common rotating abrasive devices and diamond and iron‐carbide dental burs. The “finished” surfaces were compared with surfaces created by a polyester matrix band.

Curing Dental Resins and Composites by Photopolymerization

Journal of Esthetic and Restorative Dentistry, 2000
ABSTRACTThe development and continued evolution of photopolymerizable dental materials, particularly dental composite restoratives, represent a significant, practical advance for dentistry. The highly successful integration of the light‐activated curing process for dental applications is described in this review.

Hypersensitivity to dental composites and resin-bonding agents

Dental Update, 2016
Adverse reactions to dental materials are not an uncommon occurrence, although hypersensitivity has gained much renewed interest in light of public concerns over the safety of dental materials. Hypersensitivity can affect both patients and dental professionals and may manifest as either allergic contact dermatitis or stomatitis.

Initiation of Polymerization with Ultrasound in Dental Composite Resin

Biomaterials, Artificial Cells and Immobilization Biotechnology, 1992
A single paste composite resin comprising methacrylate monomers, inorganic fillers, activators and an ultrasonic generator assembled by a piezoceramic transducer and a working tip was developed. The resin can polymerize and harden under irradiation with ultrasound having frequencies from 20 to 50 KHz and intensity from 12 to 40 W/cm2.
