Patent number: 11219582Abstract: The present invention is a formable dental treatment tray utilizing poly(2-ethyl-2-oxazoline) and a gelatinous active. Blending of the active is accomplished by mixing the Poly(2-ethyl-2-oxazoline) with an active ingredient, such as a peroxide like hydrogen peroxide, carbamide peroxide, sodium perborate, or sodium percarbonate, usually also with water or an appropriate organic solvent. Peroxide concentrations in these new gels can reach a 30% concentration of hydrogen peroxide while maintaining a shelf life of six months at room temperature without developing peroxide decomposition. The gels are applied to an appropriate backing and dried to a gelatinous state. In use, the active is hydrated and regains adhesiveness. Then the tray is pressed and formed around a user's dental arch to form the customizable tray. Multiple active ingredients may be used, with or without peroxide, for accomplishing desired treatment regimens.Type: GrantFiled: February 7, 2020Date of Patent: January 11, 2022Assignee: CAO Group, Inc.Inventor: Steven D.

Patent number: 10285789Abstract: The addition of the Iodide ion by way of Potassium Iodide to a peroxide such as Hydrogen Peroxide in a basic medium yields Free Radical Oxygen and water; generating large amounts of heat and depleting the Hydrogen Peroxide in a matter of minutes. The Free Radical Oxygen generated in this reaction can be utilized to oxidize organic molecules that produce offending stains on select items, including teeth. Once the Free Radical Oxygen has oxidized the offending molecule the color is lost and the solubility changes allowing the colorless oxidized fragments of the offending molecule to be washed away in the solvent. The Iodide ion catalyzes the reaction allowing for precise control over the speed at which the stain is removed without the need for other expensive, cumbersome energy adding equipment such as lights, lasers, heat sources, etc.Type: GrantFiled: April 19, 2007Date of Patent: May 14, 2019Assignee: CAO Group, Inc.Inventors: Robert K.

Patent number: 9872557Abstract: A delivery tip for flowable materials with bristles or fibers extending therefrom. The tip is a cannula with a tapered outlet and features a bristle or fiber bundle with a binding restriction member that interfaces with the cannula at some point within the cannula but has a smaller cross-sectional area for flow passage than the cannula at that point. The bristle or fiber bundle extends out of the tapered outlet. The delivery tip may connect to a material reservoir with flowable material. When positive pressure is applied to the reservoir, material then will flow through the cannula, around the restriction member, into the bristles or fibers and out the outlet for distribution to a desired surface.Type: GrantFiled: January 12, 2010Date of Patent: January 23, 2018Assignee: CAO Group, Inc.Inventor: Steven D.
