ROI Calculation Logic

Traditional denture manufacturing relies heavily on skilled manual labor, taking approximately 10 hours per set with an estimated labor cost of ~$330 (AI est.). This technology could reduce manufacturing time to 3 hours and labor costs to ~$130 (AI est.) per set. For a company producing 3,000 denture sets annually, this translates to ~$600K (AI est.) in labor cost reduction. Furthermore, reducing material loss from 20% to 5% could save an additional ~$400K (AI est.) in material costs annually, leading to a total estimated annual cost savings of ~$1M (AI est.).

Speed to Market
4× faster than in-house development
This technology fully digitizes the removable partial denture manufacturing process, with established proprietary 3D data processing algorithms and cutting equipment integration. The claimed steps—data creation, block creation, and cutting—are highly compatible with existing CAD/CAM systems and dental cutting devices, suggesting low barriers to new manufacturing line integration. This allows licensees to significantly shorten time-to-market compared to developing equivalent technology in-house, enabling rapid business launch.
