Latest Patents

One of her latest patents is focused on a chain-extended urethane diacrylate. This invention discloses a new urethane polyacrylate that features at least one terminal isocyanato acrylic pendent radical. The molecular chain within the acrylate caps is extended with a polyhydroxy compound before final end capping with isocyanato acrylic. The isocyanato acrylic is preferably isocyanato ethyl methacrylate, and the urethane is diisocyanate capped polyether. The method for producing this urethane polyacrylate involves end capping a polyol with diisocyanate, yielding a reaction product with two reactive equivalents of isocyanate. This is followed by capping less than all of the isocyanate with a hydroxyacrylate, after which the remaining isocyanate is reacted with polyol to provide chain extension. Additionally, she has developed a new impression material for application to mammalian tissue, which includes a free radical polymerizable resin, alkyl benzensulfonyl titanate, polymerization initiator, and filler.

Another significant patent is for a pre-loaded dental impression package. This package is designed for taking accurate impressions of a patient's teeth and/or gums by professional personnel. The impression material used is flowable to a desired degree and has a viscosity of substantially one million centipoises. The packaging process involves quickly immersing the loaded tray in a solution of natural latex, followed by a coagulating solution of acetic acid to stabilize the latex coating.
