This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,652.

Summary of the Inventive Concept

The present invention relates to an improved dental wrap system, comprising a novel adhesive layer and a backing layer, for efficient teeth whitening. The system provides a controlled release of whitening agents, improved retention on teeth, and reduced production costs.

Background and Problem Solved

The original patent described a dental wrap without active ingredients, which had limitations in terms of whitening efficiency and retention on teeth. The present inventive concept addresses these limitations by introducing a novel combination of PVP, Pullulan, and HPMC in the adhesive layer, and a thin layer of whitening agent on the backing layer, ensuring a controlled release of the whitening agent and improved retention on teeth.

Detailed Description of the Inventive Concept

The enhanced dental wrap system comprises an adhesive layer formulated with a novel combination of PVP, Pullulan, and HPMC, which provides improved viscosity and retention on teeth. The backing layer is coated with a thin layer of whitening agent, which is released in a controlled manner over a predetermined period of time. The system can be used in conjunction with a gel containing hydrogen peroxide and glycerin, applied to the dental wrap prior to use. The manufacturing process involves a novel roll-to-roll process, resulting in improved uniformity and reduced production costs.

Novelty and Inventive Step

The present inventive concept introduces a novel combination of PVP, Pullulan, and HPMC in the adhesive layer, and a thin layer of whitening agent on the backing layer, which provides a controlled release of the whitening agent and improved retention on teeth. This is a significant improvement over the original patent, which did not contain active ingredients and had limitations in terms of whitening efficiency and retention on teeth.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the composition of the adhesive layer, using different whitening agents, or modifying the manufacturing process to achieve improved uniformity and reduced production costs. Additionally, the system could be adapted for use with different types of dental wraps or oral care products.

Potential Commercial Applications and Market

The enhanced dental wrap system has significant commercial potential in the oral care industry, particularly in the teeth whitening market. The system's improved efficiency, convenience, and cost-effectiveness make it an attractive solution for consumers and dental professionals alike. The target market includes dental clinics, pharmacies, and online retailers, with potential for expansion into other oral care product categories.
