Methods of forming antimicrobial resin compositions comprising silver nanoparticles are disclosed, wherein the resin compositions that are generated exhibit lower initial color, reduced color shift upon storage and reduced levels of spontaneous polymerization. Such methods generally comprise: combining a silver-containing material with a self-cure and dual-cure base resin in situ wherein the base resin does not contain a catalytic amine; and adding a catalytic resin to the mixture of the resin and silver-containing material in order to form the final cured resin. Antimicrobial polymeric materials formed by said methods are also disclosed.

Shelf life and color profile of resin compositions with silver nanoparticles

Embodiments of the invention are directed to dental compositions comprising: (1) at least one cationically reactive compound; (2) at least one cationic photoinitiator; (3) at least one compound which is: an organic monomer, oligomer or polymer, said compound comprising at least one reactive oxirane, oxetane, or alkenyl ether, (4) at least one compound which is: an organic monomer, oligomer or polymer, said compound comprising at least one reactive acrylate that is capable of forming an interpenetrating network; (5) at least one free radical initiator; and (6) at least one compound which is: an organic monomer, oligomer or polymer, said compound comprising at least one reactive acrylate or methacrylate and at least one oxirane, oxetane, or alkenyl ether.

Restorative resin compositions and methods of use

Improving shelf life and color profile of resin compositions with silver nanoparticles

Methods of forming antimicrobial resin compositions comprising silver nanoparticles are disclosed. Such methods generally comprise: combining a silver-containing material with a resin in situ in the presence of a silver-binding compound; and curing the resin. Antimicrobial polymeric resin compositions formed by said methods have a lighter color than control compositions and also display a slower release of silver ions over time.

Improving color and release profile of resin compositions comprising silver nanoparticles

Methods of forming antimicrobial polymeric materials comprising metallic nanoparticles are disclosed. Such methods generally comprise: combining a metal-containing material with a resin in situ; and curing the resin in the presence of a metal-containing material. Antimicrobial polymeric materials formed by said methods are also disclosed.

Acrylic polymers containing metallic nanoparticles

Various embodiments of the present invention generally relate to a light-cure and dual-cure resin that have low color and is color stable over conventional light, self and dual-cured resins. Additionally, the light-cure resin has enhanced degree of cure over conventional light-cure resins. Finally, due to the low color and enhanced color stability of the dual-cure resins, their inherent property of having lower shrinkage stress as compared to light-cure resins can now be utilized in various dental applications and other resin applications.
