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

An advanced maxillary expander and protraction device that improves treatment outcomes by incorporating real-time feedback from sensors to adjust the distance between the maxilla and the hard palate, ensuring optimal bone density and minimizing potential complications.

Background and Problem Solved

Current maxillary skeletal anchorage expanders have limitations in terms of precision, efficiency, and safety. The original patent, 'Maxillary expander and protraction device', addressed transverse maxillary deficiency, but it lacked real-time feedback and customization capabilities. The new inventive concept overcomes these limitations by integrating sensors and advanced adjustment mechanisms to provide more effective and personalized treatments.

Detailed Description of the Inventive Concept

The enhanced maxillary expander and protraction device comprises at least two bodies configured to apply forces to the maxilla without any coupling to the teeth of a patient. The device features an integrated sensor to detect changes in maxillary bone density, providing real-time feedback to adjust the distance between the maxilla and the hard palate. The adjustment mechanism is powered by a rechargeable battery and can be configured to provide a customizable treatment profile based on individual patient needs. The device can be used to treat transverse maxillary deficiency and other related conditions, ensuring optimal treatment outcomes and minimizing potential complications.

Novelty and Inventive Step

The new inventive concept introduces the integration of sensors and advanced adjustment mechanisms, enabling real-time feedback and customization capabilities that are not present in the original patent. These features provide a significant improvement in treatment outcomes, precision, and safety, making the new concept novel and non-obvious compared to the prior art.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include different types of sensors, such as ultrasound or X-ray sensors, to detect changes in maxillary bone density. The device could also be designed for use in other orthodontic or orthognathic treatments, such as mandibular advancement or craniofacial reconstruction. Additionally, the device could be integrated with artificial intelligence or machine learning algorithms to optimize treatment plans and predict outcomes.

Potential Commercial Applications and Market

The enhanced maxillary expander and protraction device has significant commercial potential in the orthodontic and orthognathic markets. The device could be marketed to orthodontists, oral surgeons, and other healthcare professionals, offering a more effective and efficient treatment option for patients with transverse maxillary deficiency and related conditions. The device could also be used in research settings to advance the understanding of maxillary bone density and its relationship to orthodontic treatments.
