Publication number: 20050154081Abstract: Polymerizable compositions are described containing colored polymerization indicators which confer a visible color on the unpolymerized compositions. Upon polymerization, the compositions exhibit reduced or eliminated color. The compositions can also change their opacity during polymerization. The compositions provide easy visual differentiation between the unpolymerized compositions and substrates on which the compositions are placed. The compositions are useful in clinical and laboratory applications such as those involving teeth, dental implants, orthodontic materials, artificial teeth and bones.Type: ApplicationFiled: January 9, 2004Publication date: July 14, 2005Applicant: BISCO, INC.Inventors: Rui YIN, Byoung SUH, Oanh MAI, Keith HAYES, Louis SHARP

Patent number: 6709271Abstract: Dental composite compositions, restorative compositions, and methods for their use are provided. The compositions can contain (a) from about 1 to about 35 weight percent of a monomer portion containing at least one monomer having a functional group capable of undergoing polymerization; (b) from about 75 to about 95 weight percent of a filler portion, the filler portion containing at least a spherical filler portion having at least one spherical filler particle component; and (c) from about 0.01 to about 10 weight percent of a polymerization catalyst portion containing at least one catalyst capable of assisting in the polymerization of the functional group of the monomer portion and hardening of the composite after application of the composite to a tooth surface or other dental surface. The spherical filler portion is present in an amount sufficient to reduce shrinkage of the composite after polymerization to about 1.8 percent or less.Type: GrantFiled: November 20, 2001Date of Patent: March 23, 2004Assignee: Bisco, Inc.Inventors: Rui Yin, Byoung In Suh, Louis Sharp, Amer Tiba
