ROI Calculation Logic

Assuming 1% of domestic denture wearers (approx. 100,000 patients) adopt this technology. Annual savings per patient from residual root preservation and halved denture replacement costs: $10/person (AI est.). Total annual healthcare cost and patient burden reduction: $10/person × 100,000 patients = ~$1M (AI est.).

Speed to Market
6× faster than in-house development
The technology's concept is clear and relatively easy to apply to existing dental material processing techniques and denture manufacturing processes. The magnet housing and keeper structures described in the patent claims and detailed specifications can be realized using general-purpose CAD/CAM technology, precision casting, or resin molding techniques, suggesting a low need for new fundamental technology development. Therefore, adopting companies could achieve rapid product commercialization and market entry by integrating into existing manufacturing lines and optimizing designs, without requiring significant R&D investment or long development periods.

Technical Feasibility
This technology is estimated to have high compatibility with existing dental material processing techniques and denture manufacturing processes, involving the formation of a magnet housing in the denture base and keeper fixation to residual roots. The components described in the patent claims, such as the 'housing recess,' 'magnet storage space,' 'inward flange,' and 'keeper insertion hole,' can be realized through general-purpose CAD/CAM design, 3D printing, or precision casting/resin molding techniques, making it highly probable for integration into existing denture manufacturing lines without significant capital investment.
Success Scenario
Adopting this technology could enable companies to offer innovative products that address two major needs of denture wearers: 'improved meal quality' and 'long-term oral health maintenance.' Compared to conventional dentures, patient satisfaction may increase by 20%, and extending the average denture replacement cycle from 2 to 4 years could strengthen long-term customer engagement. This could establish a clear differentiation factor against competitors and build market advantage.
