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. 11,857,230.

Summary of the Inventive Concept

A maxillary expander and protraction device designed for high-security needs, disaster relief, extreme weather conditions, remote or isolated areas, and high-altitude environments, providing a reliable and adaptable solution for treating patients with transverse maxillary deficiency in various operational environments.

Background and Problem Solved

Current maxillary skeletal anchorage expanders are limited in their applicability to specific operational environments, such as high-security settings, disaster relief situations, or extreme weather conditions. The original patent does not address these unique challenges, leaving a gap in the market for a maxillary expander and protraction device that can effectively treat patients in these specialized environments.

Detailed Description of the Inventive Concept

The inventive concept comprises a maxillary expander and protraction device with at least two bodies configured to be coupled to a maxilla of a patient and/or to an appliance that is at least in part extra-oral. The device applies forces to the maxilla without any coupling of the device to the teeth of a patient, ensuring adaptability to various operational environments. The device further includes features such as tamper-evident mechanisms, weather-resistant coatings, self-contained power sources, and pressure-compensating mechanisms, depending on the specific environment it is designed to operate in.

Novelty and Inventive Step

The inventive concept introduces novel features and combinations of features that are specifically designed to address the unique challenges of high-security needs, disaster relief, extreme weather conditions, remote or isolated areas, and high-altitude environments. The inventive concept's adaptability to various operational environments and its ability to apply forces to the maxilla without coupling to the teeth of a patient represent a significant departure from the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include devices with adjustable or removable components, devices with integrated sensors for monitoring patient progress, or devices with modular designs for easy customization to specific environments. Variations of the inventive concept could also include devices designed for specific age groups or patient populations, such as pediatric or geriatric patients.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the orthodontic and dental industries, particularly in niche markets such as high-security facilities, disaster relief organizations, and remote or isolated areas. The device's adaptability to various operational environments and its ability to treat patients with transverse maxillary deficiency in these settings make it an attractive solution for healthcare providers and patients alike.

Field of Art

Medical Device Engineering, specifically Orthodontic and Maxillofacial Surgical Devices, focusing on maxillary expansion and skeletal anchorage technologies

Person of Ordinary Skill (PHOSITA) Profile

A biomedical engineer or orthodontic device specialist with advanced degree, expertise in medical device design, understanding of biomechanical principles, and knowledge of surgical intervention techniques for maxillary correction

Obviousness Rationale

A PHOSITA would recognize that the PTD represents predictable variations of the source patent's core maxillary expander technology by adapting the fundamental mechanical design to specialized environmental contexts. The core mechanical principles of bone screw attachment, expansion mechanisms, and force application remain consistent, with the PTD merely introducing contextual modifications that would be considered routine engineering adaptations. The variations represent logical extensions of the original patent's core technological concept, applying known design principles to address specific operational environments.

Obvious Combinations & Variations

Source Patent Element
Bone screws configured to screw into hard palate with first and second apertures
PTD Variation
Adding tamper-evident mechanisms to prevent unauthorized adjustments of bone screw configurations
Obviousness Reasoning

Source Patent Element
First bodies with multiple aperture configurations for bone screw and fastener attachment
PTD Variation
Adding weather-resistant coatings to prevent corrosion and maintain structural integrity in extreme environmental conditions
Obviousness Reasoning
Applying protective coatings to medical devices to enhance durability is a well-known technique that would be obvious to a PHOSITA seeking to improve device performance
Source Patent Element
Maxillary expander designed for transverse arch expansion
PTD Variation
Implementing pressure-compensating mechanisms for high-altitude medical interventions
Obviousness Reasoning
Adapting medical devices to account for environmental pressure variations is a predictable engineering solution for maintaining device performance across different operational contexts
35 U.S.C. § 103 Summary: Pursuant to 35 U.S.C. ยง 103, the variations disclosed in this Published Technical Disclosure (PTD) would be considered obvious extensions of US Patent 11857230, as they represent routine engineering adaptations of the source patent's core maxillary expander technology. A Person Having Ordinary Skill In The Art would recognize these modifications as predictable variations that do not constitute non-obvious innovation, thereby rendering potential derivative patent claims anticipated and obvious in light of the existing technological disclosure.
