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 novel orthognathic treatment system utilizing maxillary expanders to treat various craniofacial disorders, including sleep apnea, snoring, temporomandibular joint disorders, facial asymmetry, and craniosynostosis.

Background and Problem Solved

Current maxillary skeletal anchorage expanders are limited to treating transverse maxillary and anterior-posterior deficiencies. However, there is a growing need to address craniofacial disorders that require innovative solutions. The new inventive concept leverages the core technology of the original patent to expand its applications to entirely new industries and fields.

Detailed Description of the Inventive Concept

The inventive concept comprises a maxillary expander, an adjustment mechanism, and a cranial anchor. The maxillary expander is configured to apply forces to the maxilla without coupling to the teeth, allowing for lateral movement to increase airway volume, relieve pressure on the temporomandibular joint, or correct facial asymmetry. The adjustment mechanism variably maintains a distance between the maxillary expander and the cranial anchor, ensuring precise control over the treatment process. The system can be integrated with sensors and guidance systems to provide real-time feedback and optimize treatment outcomes.

Novelty and Inventive Step

The new inventive concept introduces a paradigm shift in orthognathic treatment by applying the core technology of maxillary expanders to a broad range of craniofacial disorders. The novel combination of components and operation enables a non-obvious expansion of the original patent's scope, providing a unique solution to address unmet clinical needs.

Alternative Embodiments and Variations

Alternative embodiments may include customizable maxillary expanders, adjustable cranial anchors, and integrated sensors for real-time monitoring. Variations may also involve adapting the system for pediatric or adult patients, or incorporating AI-powered guidance systems for personalized treatment planning.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the orthognathic treatment market, with applications in sleep medicine, oral surgery, orthodontics, and craniofacial reconstruction. The system's versatility and adaptability make it an attractive solution for clinicians and patients seeking innovative treatments for craniofacial disorders.
