    摘要: Chelating monomers and fluoride-releasing compositions are disclosed that may be incorporated into dental composite restorative materials or other dental materials, to produce materials with high fluoride release rates, and high fluoride recharge capability. Such resins may be used in dental restorative materials to help reduce the level of dental caries in patients, particularly the level of caries occurring on the margins of the restorative materials.

    摘要: The present invention relates to polymer-brush modified fillers and methods, compositions and processes of modification of fillers and more particularly fillers useful in dental materials and other compositions that exhibit higher mechanical strength, longer hydrolytic stability, lower polymerization stress and improved wear and abrasion resistance. The present invention provides a method for making a polymer-brush modified filler comprising: providing a filler material; silanizing the filler material with a silane; and reacting the silanized filler with a telechelic oligomer. The present invention further provides a method of preparing a shaped dental prosthetic device for use in a human mouth comprising: dispensing a mixture having at least one monomer and a polymer brush modified filler; shaping the mixture; and photopolymerizing the mixture.
