Improving 3d-printed Patient-matched Implants with Digital Twin Technology for Metrology

Additive manufacturing allows for highly customizable patient-specific design with morphologies optimal for osteogenesis. Control of the lattice structure has been demonstrated to improve patient outcomes post-surgery. However, the osseointegration process is highly dependent upon proper geometric characteristics and porosity of the 3D-printed lattice structure. Individualized medical approaches like these are prone to high variability in production, making the implementation of quality control checks a challenge. Using industrial CT technology to produce a digital twin of the component, it’s possible to evaluate structural integrity, porosity, roughness of internal surfaces, internal defects, and impurities to ensure adequate quality to promote osseointegration successfully. This session will explain how to use CT technology to digitize 3D-printed medical implants for the measurement of geometry, porosity, trabeculation patterns, and surface roughness, resulting in benefits like improved fit, enhanced functionality, reduced surgical time, faster recovery, reduced risk of complications, minimized bone loss, and higher patient satisfaction.
