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).
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.

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,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. 2. A non-customized dental treatment tray as in claim 1, wherein the non-silicone, silicone-like thermoplastic elastomer comprises styrene-ethylene-butylene-styrene thermoplastic elastomer. 3. A non-customized dental treatment tray as in claim 1, wherein the non-silicone, silicone-like thermoplastic elastomer is a thermoplastic elastomer alloy. 4. A non-customized dental treatment tray as in claim 3, wherein the thermoplastic elastomer alloy has a shore A hardness of 43 or below. 5. A non-customized dental treatment tray as in claim 1, wherein the non-customized barrier layer has a thickness of less than about 1.5 mm. 6. A non-customized dental treatment tray as in claim 1, wherein the non-customized barrier layer has a thickness of less than about 1 mm. 7. A non-customized dental treatment tray as in claim 1, wherein the non-customized barrier layer has a thickness of less than about 0.5 mm. 8. A non-customized dental treatment tray as in claim 1, wherein the moisture-resistant elastomeric material of the barrier layer is blended with at least one auxiliary component selected from the group consisting of elastomers, latexes, water, plasticizers, and nitriles. 9. A non-customized dental treatment tray as in claim 1, wherein the moisture-resistant elastomeric material has an elasticity between about 2% and about 2000%. 10. A non-customized dental treatment tray as in claim 1, wherein the moisture-resistant elastomeric material has an elasticity between about 100% and about 1000%. 11. A non-customized dental treatment tray as in claim 1, wherein the elastomeric material further includes more than 0% and up to about 10% by weight of an auxiliary component.
