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. 11,857,654.

Summary of the Inventive Concept

A next-generation oral care system utilizing nanohydroxyapatite in a biodegradable polymer matrix, integrated with sensors and bioactive molecules, providing personalized oral care and real-time monitoring of oral health.

Background and Problem Solved

The original patent disclosed an alkaline dental composition containing nanohydroxyapatite, but it had limitations in terms of controlled release, bioavailability, and personalized oral care. The new inventive concept addresses these limitations by introducing a biodegradable polymer matrix, bioactive molecules, and sensors to create a more effective and personalized oral care system.

Detailed Description of the Inventive Concept

The inventive concept comprises a nanohydroxyapatite-based oral care composition encapsulated in a biodegradable polymer matrix, allowing for controlled release of the nanohydroxyapatite over an extended period. The composition further includes a bioactive molecule that promotes tooth remineralization. The system also incorporates a sensor for detecting changes in oral pH levels, enabling real-time monitoring of oral health. Additionally, the composition is designed to adapt to an individual's unique oral microbiome, providing personalized oral care. The system can be fabricated using a method involving forming a nanohydroxyapatite suspension, mixing it with a biodegradable polymer, and extruding the mixture into a desired shape.

Novelty and Inventive Step

The new claims introduce the concept of encapsulating nanohydroxyapatite in a biodegradable polymer matrix, integrating sensors and bioactive molecules, and adapting to individual oral microbiomes, which are novel and non-obvious compared to the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of biodegradable polymers, varying the concentration of nanohydroxyapatite, or incorporating additional bioactive molecules. The system could also be adapted for use in veterinary oral care or as a preventative measure for oral diseases.

Potential Commercial Applications and Market

The personalized nanohydroxyapatite-based oral care system has significant commercial potential in the oral care industry, particularly in the areas of preventative care, personalized medicine, and real-time health monitoring. The system could be marketed as a premium oral care product, targeting consumers seeking advanced and personalized oral health solutions.
