US Patent:

43245498, Apr 13, 1982

Filed:

Sep 26, 1980

Appl. No.:

6/191019

Inventors:

George W. Madray - Brunswick GA

International Classification:

A61C 1328

US Classification:

433169

Abstract:

The invention has two main parts. First, there is an assembly of elements including a prefabricated precision stud, or male element, preferably made of metal, as stainless steel for example, securely anchored by a specially designed cap fitting onto a prepared matching outer end of a tooth, and a second assembly of elements including a prefabricated thimble, or female part, preferably made of plastic material. The thimble element is provided, at its outer upper region, with burrs, or projections, so that the thimble element may be rigidly held in the denture material, but the skirt or lower region of the thimble element does not contact the denture material and may thus flex, or stretch, circumferentially, and thus expand radially, to receive the stud element with a snap action, so that the two main parts are snap retained to each other. The thimble element should be made available in a tissue-resilient type, and somewhat more non-resilient type, to match the need, for example, in the tissue-resilient type it would be used when the denture is supported more by the gum than by the teeth, whereas in the non-resilient type it would be used when the denture is supported more by the teeth than by the gum. The anchor provided by this invention creates a favorable crown-root ratio where there is minimal inter-occlusal space, approximately 3 mm.

Abstract:

A method for manufacturing molecular chlorine dioxide, by the addition of potassium iodide to a solution of alkali metal chlorite. The metal chlorite and the potassium iodide are kept separate, until the need for the generation of chlorine dioxide arises--to ensure long-shelf life. After initiation or activation of the chlorite anion to form chlorine dioxide, the beneficial properties of chlorine dioxide can be used, for different health and cosmetic purposes. Such uses include the treatment of herpes, dandruff, acne, skin rashes (e. g. poison ivy), ulcers, bed sores, warts, nail fungus, athletes foot, sun burn and gum disease; and as an antiseptic, disinfectant, and general deodorant form refrigerator sprays to oral mouthrinses.

US Classification:

Abstract:

An improved method for bleaching teeth using a pre-formed stock tray of a thermoplastic material with a low-heat melt-index, and a peroxide gel. The tray is custom fitted at home by the wearer, instead of having to go to a dentist. It is placed in boiling water a few seconds to soften, and is adapted snugly over the teeth in one arch. An oxidizing gel of an over-the-counter oral antiseptic is placed inside the tray, which in turn is placed over the teeth. After a period of time the gel is replenished again. This is done several times throughout the day, and continued for 2-3 weeks. The end result being whiter teeth and a new smile.
