Conventional mandibular fixation relies on rigid titanium plates that are significantly stiffer than bone. This mismatch disrupts natural load transfer.
Despite advances in geometry and customization, surgeons still lack tools to evaluate how fixation will perform in a specific patient.
RegenFix is developing a biomechanics-driven fixation platform that combines:
Addressing the fundamental mismatch between implant stiffness and bone — a key driver of stress shielding and long-term device failure. RegenFix pairs stiffness-matched Nitinol implants with patient-specific biomechanical simulation to restore physiologic loading, improve healing outcomes, and reduce revision risk.

Large-animal preclinical validation completed. Results demonstrated alignment between predicted and observed biomechanical performance and supported successful healing using personalized porous NiTi fixation hardware.

Porous NiTi fixation plates achieved bone-like mechanical properties. Engineered porous architectures reduced implant stiffness into the cortical bone range while maintaining structural integrity and fatigue resistance under cyclic loading. The study demonstrated that engineered porosity can be used to create fixation devices that better match the mechanical behavior of bone while reducing stress shielding and stress concentration.

Virtual Surgical Planning enables optimization before surgery. Computational models can evaluate implant location, material selection, and geometry to help reduce stress shielding and stress concentration while supporting personalized stiffness-matched reconstruction strategies. This work establishes the foundation for biomechanics-driven treatment planning and future personalized implant optimization workflows.
