What This Patent Covers

This patent protects a free-end denture and its attachment mechanism, specifically detailing a spherical protrusion on the dental crown and an elastic, comb-shaped engaging part on the denture base. The claims define the elastic engagement and disengagement mechanism, ensuring stable attachment during chewing and easy removal. The patent successfully navigated a rejection, indicating clear and robust claim scope.

Competitive White Space

This patent primarily covers the mechanical engagement of the denture. White space exists in areas such as advanced material science for enhanced biocompatibility, smart sensing for real-time fit adjustments, or integration with digital dentistry workflows like intraoral scanning and AI-driven design.

Economic Impact

ROI Calculation Logic

Implementing this technology could reduce annual labor for denture adjustments and repairs by ~20%. For a clinic with 5 dentists/technicians, this represents annual personnel cost savings of ~$40K (AI est.). Furthermore, enhanced patient satisfaction could generate ~$40K (AI est.) in new patient revenue (assuming 10 new patients/year at ~$4K/treatment). This totals over ~$80K (AI est.) in annual economic impact.

Speed to Market
6× faster than in-house development
Implementing this technology could shorten time-to-market by approximately 2.5 years compared to developing a similar denture attachment system in-house. The patent details the precise structure of the spherical protrusion and elastic comb-shaped engaging part, along with its elastic engagement mechanism. This clear documentation allows for significant acceleration of the R&D phase by establishing manufacturing processes based on the patent, enabling early product commercialization and market leadership.
