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. 11,857,653.

Summary of the Inventive Concept

This inventive concept discloses a system and method for providing enhanced oral care benefits through controlled delivery of a poorly-soluble calcium compound and fluoride, resulting in improved remineralization and anti-caries benefits.

Background and Problem Solved

The original patent (Method of providing an oral care benefit using a poorly-soluble calcium compound and fluoride) has limitations in terms of the timing and manner of delivering the calcium compound and fluoride. The new inventive concept addresses these limitations by introducing controlled delivery vehicles, pH buffering agents, bioadhesive polymers, and sequential release mechanisms to optimize the reaction between the calcium compound and fluoride.

Detailed Description of the Inventive Concept

The new inventive concept comprises a system for providing enhanced oral care benefits, including a poorly-soluble calcium compound delivery vehicle and a fluoride delivery vehicle. The calcium compound delivery vehicle is designed to release the poorly-soluble calcium compound in a controlled manner to optimize reaction with the fluoride. Additionally, a pH buffering agent can be introduced to the oral cavity prior to introducing the poorly-soluble calcium compound and fluoride to further enhance the reaction. The composition for providing oral care benefits includes a poorly-soluble calcium compound, fluoride, and a bioadhesive polymer, which enhances the retention of the calcium compound and fluoride in the oral cavity. The method of providing oral care benefits involves introducing a poorly-soluble calcium compound to the oral cavity via a mouthwash or mouthrinse, and subsequently introducing fluoride via a toothpaste or gel, with a delayed release profile. A device for delivering oral care benefits includes compartments for containing a poorly-soluble calcium compound and fluoride, designed to release the calcium compound and fluoride in a sequential and controlled manner.

Novelty and Inventive Step

The new claims introduce novel elements such as controlled delivery vehicles, pH buffering agents, bioadhesive polymers, and sequential release mechanisms, which are not present in the original patent. These elements provide a non-obvious solution to the limitations of the original patent, resulting in improved oral care benefits.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the type of poorly-soluble calcium compound, the formulation of the fluoride, and the design of the delivery vehicles. Additionally, the inventive concept could be adapted for use in different oral care products, such as mouthwashes, toothpastes, or dental varnishes.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the oral care industry, particularly in the development of new products that provide enhanced remineralization and anti-caries benefits. The target market includes consumers seeking improved oral health, as well as dental professionals and oral care companies looking to develop innovative products.

Field of Art

Oral care compositions and delivery systems, specifically focused on remineralization and anti-caries treatments involving calcium compounds and fluoride interactions

Person of Ordinary Skill (PHOSITA) Profile

A dental materials scientist or formulation chemist with expertise in oral care product development, familiar with dental chemistry, polymer science, and controlled release technologies

Obviousness Rationale

A PHOSITA would recognize that the PTD's variations represent predictable extensions of the source patent's core method by introducing standard formulation techniques like controlled release, bioadhesive polymers, and sequential delivery mechanisms that are well-known in oral care product development. The fundamental scientific principle of calcium compound and fluoride interaction remains unchanged, with the PTD merely proposing incremental improvements in delivery and efficacy.
