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 adapts the original method of providing oral care benefits using poorly-soluble calcium compounds and fluoride for specific, high-need markets, including high-altitude environments, emergency response situations, extreme cold weather environments, high-security environments, and disaster relief situations.

Background and Problem Solved

The original patent disclosed a method for providing oral care benefits using poorly-soluble calcium compounds and fluoride. However, this method may not be effective in extreme environments where users face unique challenges, such as low atmospheric pressure, limited access to clean water, or high-security risks. The new inventive concept addresses these limitations by introducing specialized variations of the original method tailored to these specific niches.

Detailed Description of the Inventive Concept

The inventive concept comprises a system, method, or composition for providing oral care benefits in extreme environments. In the high-altitude environment embodiment, the poorly-soluble calcium compound is adapted for low atmospheric pressure. In the emergency response situation embodiment, the oral care kit is portable and self-contained. In the extreme cold weather environment embodiment, the composition is adapted for low temperatures and administered in a single, unitary dose. In the high-security environment embodiment, the oral care delivery system is secure and tamper-evident. In the disaster relief situation embodiment, the oral care solution is water-purified. In each embodiment, the poorly-soluble calcium compound is administered prior to introducing fluoride to the oral cavity, forming calcium-bound fluoride deposits in plaque, on teeth, and in oral tissue.

Novelty and Inventive Step

The new inventive concept introduces novel adaptations of the original method, including specialized formulations, delivery systems, and administration protocols tailored to specific extreme environments. These adaptations are non-obvious and provide a significant improvement over the original patent.

Alternative Embodiments and Variations

Other embodiments of the inventive concept could include oral care solutions for space exploration, tropical environments, or areas with limited access to dental care. Variations could include using different types of poorly-soluble calcium compounds, alternative fluoride sources, or incorporating additional oral care ingredients.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the oral care industry, particularly in niche markets such as high-altitude tourism, emergency response services, extreme weather gear, high-security facilities, and disaster relief organizations. The market for specialized oral care solutions is growing, driven by increasing awareness of oral health and the need for tailored solutions in unique environments.

Field of Art

Oral care chemistry and pharmaceutical compositions, specifically focused on dental remineralization techniques involving calcium compounds and fluoride delivery systems

Person of Ordinary Skill (PHOSITA) Profile

A dental materials scientist or pharmaceutical formulation expert with advanced degree, knowledge of oral chemistry, experience in developing dental care products, and understanding of material adaptation for different environmental conditions

Obviousness Rationale

A skilled practitioner would recognize that the core oral care mechanism from the source patent can be readily adapted to specialized environments by modifying delivery systems, formulation parameters, and administration protocols while maintaining the fundamental chemical interaction between poorly-soluble calcium compounds and fluoride. The PTD's variations represent predictable engineering solutions that extend the original patent's core method to address specific use cases with routine modifications well within a PHOSITA's capabilities.
