Resin composite restorative materials [PDF]

Australian Dental Journal, 2011
AbstractThis paper surveys the most important developments in resin‐based dental composites and focuses on the deficits (e.g. polymerization shrinkage) and strengths of the materials and their clinical implications. Moreover, differences between composite categories, such as hybrid, nanohybrid, microfilled, packable, ormocer‐based, silorane‐based ...

Development of polymer network of phenolic and epoxies resins mixed with linseed oil: pilot study [PDF]

, 2010
Epoxy resin was mixed with phenolic resins in different percentages by weight. Composite 40/60 means the proportion by weight of epoxy resin is 40 percent. It was found that only composites 50/50 and 40/60 could be cured in ambient conditions. Dynamic

Interfacial microscopic examination and chemical analysis of resin-dentin interface of self-adhering flowable resin composite [version 4; referees: 2 approved]

F1000Research, 2018
Background: The newly introduced self-adhering flowable resin-composites decrease the required time for application by incorporation of an acidic adhesive monomer, thus reducing the number of steps, but its bonding is still uncertain.

Properties of electrical tree resistance of silicone‐modified epoxy resin matrix composites

IET Science, Measurement & Technology, 2023
In order to improve the electrical tree resistance of epoxy resin, composites were prepared using dihydroxydiphenylsilane and a novel silicone modifier modified epoxy resin and micron silica, and the composites were subjected to accelerated thermal aging
