DENTAL TREATMENT DEVICES COMPRISING SILICONE-LIKE ELASTOMERIC MATERIAL

摘要

Non-customized dental treatment trays used to provide a desired treatment are formed from elastomeric silicone or silicone-like material. They may be molded from a two-part liquid silicone composition or a silicone-like TPE material (e.g., preferably SEBS and/or VERSAflex thermoplastic elastomer). The dental treatment trays possess high adaptability, flexibility, softness, and elastic elongation while also exhibiting resiliency in order to readily conform to the ridges, depressions and contours of a person's teeth during use. The trays possess a greater ability to adhere to a person's teeth compared to non-elastomeric thermoplastic materials. Due to their high adaptability and conformability, the non-customized dental trays behave like a semi-custom dental tray when placed over conformed to a person's teeth, particularly when used in combination with a sticky, viscous treatment composition.

主权项

1. A non-customized dental treatment tray for use in applying a dental treatment composition to a person's teeth and/or gums and which is highly adaptable in order to approximate the comfort and fit of a customized dental tray, comprising:
a non-customized barrier layer formed from a moisture-resistant elastomeric material in the shape of a dental tray, wherein the non-customized barrier layer is devoid of structures corresponding to a size and shape of a person's unique dentition so as to comfortably fit over a plurality of differently-sized and shaped teeth and dental arches corresponding to different people, wherein the elastomeric material consists essentially of a non-silicone, silicone-like thermoplastic elastomer having a Shore A hardness of 45 or below, and optionally less than about 10% by weight of an auxiliary component, wherein the non-customized barrier layer is soft, flexible and elastically deformable in order to be highly adaptable so that, when placed over a person's teeth during use, the non-customized barrier layer adapts and at least partially conforms to unique ridges, depressions and contours of the person's teeth.
