Prosthetic device for temporomandibular joint and corresponding prosthetic assembly

Overview This patented invention introduces a patient-specific temporomandibular joint (TMJ) prosthetic assembly designed to revolutionize TMJ replacement surgeries. By combining a customized condylar component with an dedicated surgical guide template, the system enables precise, minimally invasive joint reconstruction.

Key Features & Technological Advantages

• Latero-Medial Insertion: Features an innovative anchoring element (lamella) designed for latero-medial insertion, drastically simplifying surgical delivery via a single pre-auricular incision.

• Maximum Bone Preservation: Requires minimal bone resection compared to bulky traditional TMJ prostheses, preserving maximum natural condylar structure.

• Patient-Specific Precision: Custom-manufactured (via additive manufacturing/3D printing in biocompatible materials such as titanium and UHMWPE) to perfectly match the patient's anatomy.

• Superior Osseointegration: The anchoring lamella features structured surface treatments (such as comb-like macro-grooves, micro-grooves, or trabecular lattice structures) to promote cancellous bone growth and primary mechanical stability.

• Dedicated Piezoelectric Surgical Guide: Included custom surgical template guarantees accurate osteotomy contours and precise seating preparation, reducing surgical risks and procedure times.

Target Applications & Market Opportunity

• Ideal first-line treatment for non-extensive TMJ pathologies: osteoarthrosis, condylar resorption, and benign neoplasms.

• Suitable for patients with failed previous functional arthroplasties.

• Expands implant eligibility to a broader patient base by offering shorter recovery times and reduced surgical invasiveness.

Licensing Opportunity We are seeking qualified industrial partners, medical device manufacturers, and distributors interested in licensing this technology to commercialize next-generation TMJ surgical solutions.
