ROI Calculation Logic

This technology could improve patient satisfaction, leading to increased repeat visits and new patient referrals for dental clinics. For example, assuming 500 new denture patients annually, a reduction of ~$350/patient/year (AI est.) in adjustment/maintenance costs, plus 20 new patients acquired via referrals at an average treatment cost of ~$1,350/patient (AI est.), the estimated economic impact is ($350 imes 500) + ($1,350 imes 20) = $175,000 + $27,000 = ~$200K/year (AI est.).

Speed to Market
6× faster than in-house development
This technology's fundamental denture and attachment structure is already established by the patent, significantly reducing the need for new basic research and mechanical design. Key insights regarding magnetic material selection, precision-machined fitting part design, and the occlusal sliding mechanism are detailed in the patent specification. This allows licensees to efficiently integrate the technology into existing denture manufacturing lines and accelerate clinical trials for medical device approval.

Technology Evaluation & Design Optimization
Duration: 3 months
Conduct a detailed evaluation of the patented technology, verifying compatibility with the licensee's existing denture manufacturing processes and materials. Optimize attachment component design using CAD/CAM and define specifications for prototype production.
Prototyping & Pre-clinical Validation
Duration: 6 months
Produce prototypes of the attachment components based on the optimized design. Conduct pre-clinical trials, including lab-level durability tests, functional evaluations, and biocompatibility assessments, to confirm safety and efficacy as a medical device.
Clinical Trials & Mass Production Preparation
Duration: 9 months
Conduct clinical trials for medical device approval. Based on the results, establish manufacturing processes, build quality control systems, and prepare for mass production. Final adjustments for market launch will be made.
Technical Feasibility
This technology, centered on magnetic materials and precision-machined fitting parts, is highly compatible with existing dental material manufacturing techniques and CAD/CAM systems. The denture-side attachment is embedded within the denture, and the abutment-side attachment is secured to a metal crown, suggesting relatively easy integration into current dental laboratory processes. The patent claims clearly define the specific structure, providing clear design guidelines and thus a low technical barrier for adoption.
Success Scenario
Upon adopting this technology, licensees could dramatically improve patient denture experiences by resolving traditional issues such as occlusal instability and difficulty in attachment/detachment. This could lead to enhanced patient satisfaction, increased repeat visits to dental clinics, and a rise in new patient referrals. Consequently, licensees may achieve significant differentiation from competitors and establish a premium product position in the market.
