3D Printing and Patient-Specific Implant Geometry
Additive manufacturing, or 3D printing, has moved from a prototyping tool to a primary manufacturing method for complex implants. Using high-resolution imaging, surgeons can now order implants that are a perfect geometric match for a patient's unique skeletal structure.
This is particularly transformative for complex spinal surgeries and maxillofacial reconstructions where standardized sizes often fall short. Beyond the shape, 3D printing allows for the creation of "lattice" structures—internal porous architectures that are impossible to create with traditional milling. These pores act as a scaffold, allowing the patient's natural bone to grow through the implant itself. This biological integration provides far superior stability compared to traditional mechanical fixations and reduces the "stress shielding" effect that can lead to bone loss over time.
