Patent number: 6814794Abstract: Temporary dental cements used to temporarily affix a dental prosthesis or appliance to a tooth or other dental substrate includes one or more soothing agent to prevent or reduce tooth sensitivity. The temporary dental cement includes a mixture of an ion leaching agent, polycarboxylic acid, a soothing agent and water. The soothing agent (e.g., 2-ethoxybenzoic acid and 2-methoxy-4-methylphenol) is added in an amount so as to reduce or eliminate tooth sensitivity associated with the reaction between the polycarboxylic and the ion leaching agent (base). The temporary cement composition is sufficiently hydrophilic that it can be readily removed from the tooth when it is desired to permanently restore the tooth.Type: GrantFiled: November 6, 2002Date of Patent: November 9, 2004Assignee: Ultradent Products, Inc.Inventor: Peter M. Allred

Patent number: 6814801Abstract: A method is disclosed for producing high quality semi-insulating silicon carbide crystals in the absence of relevant amounts of deep level trapping elements. The invention includes the steps of heating a silicon carbide crystal having a first concentration of point defect related deep level states to a temperature above the temperatures required for CVD growth of silicon carbide from source gases, but less than the sublimation temperature of silicon carbide under the ambient conditions to thereby thermodynamically increase the number of point defects and resulting states in the crystal, and then cooling the heated crystal to approach room temperature at a sufficiently rapid rate to maintain a concentration of point defects in the cooled crystal that remains greater than the first concentration.Type: GrantFiled: June 24, 2002Date of Patent: November 9, 2004Assignee: Cree, Inc.Inventors: Jason Ronald Jenny, David Phillip Malta, Hudson McDonald Hobgood, Stephan Mueller, Valeri F.
