Patent number: 6783810Abstract: A photopolymerizable material is exposed to light to effect curing. A portion of the material is exposed to light in a conventional manner, while at least one other portion of the material is masked from direct exposure to the light by use of a mask (10) having at least one mask segment (11) which either completely or at least partially blocks the light. In this manner, the polymerization stress associated with the cured materials is limited or minimized due to extended molecular relaxation promoted by this controlled or hybrid curing technique. Also according to the invention, different segments (30, 31) of a material to be cured (22) are exposed to different wavelengths of light energy (21) or one such segment (30, 31) is exposed to light energy while another such segment is not.Type: GrantFiled: March 15, 2001Date of Patent: August 31, 2004Assignee: Dentsply Research & Development Corp.Inventors: Xiaoming Jin, Paul D.

Patent number: RE38721Abstract: The polymerizable dental isolation barrier has a monomer and an initiator. The barrier composition has at least one additive including a polymer strength reducer, a wet tissue adherence accentuator, and a reflective material. The polymer strength reducer is an organic compound that prevents complete polymerization. The tissue adherence accentuator enables the barrier to adhere to a dental substrate even after polymerization. The reflective material lowers the reaction rate and lowers the production of excess heat to reduce patient discomfort and to avoid tissue damage.Type: GrantFiled: December 19, 2001Date of Patent: April 12, 2005Assignee: Ultradent Products, Inc.Inventors: Steven D. Jensen, Dan E. Fischer
