Evaluation of the Safety, Feasibility, and Early Clinical Outcomes of Patient-Specific Bone Defect Implants Fabricated From Titanium Alloy (Ti-6Al-4V) Using 3D Printing Technology
Sponsor: VinUniversity
Summary
The goal of this clinical trial is to evaluate the safety and feasibility of patient-specific bone defect implants fabricated from Ti-6Al-4V using 3D printing technology and to assess early clinical outcomes within the first 12 months following implantation of these customized devices. The main question it aims to answer is: "In patients with bone defects requiring surgical reconstruction, are patient-specific bone defect implants fabricated from titanium alloy (Ti-6Al-4V) using 3D printing technology - designed and produced at VinUni, safe and feasible for clinical use, and do they result in favorable early clinical outcomes within the first 12 months following implantation?"

Patient-specific 3D-printed Ti-6Al-4V bone implant
The investigational device is a patient-specific bone implant manufactured from titanium alloy Ti-6Al-4V using metal additive manufacturing technology. The implant is designed individually for each patient based on medical imaging data (CT or MRI), which are converted from DICOM format into three-dimensional digital models for anatomical reconstruction and implant design. The device is fabricated using selective laser melting (SLM) technology, in which high-power laser beams selectively fuse layers of Ti-6Al-4V powder to produce the final implant geometry. The manufacturing process is performed on a metal additive manufacturing system under an inert gas environment to prevent oxidation and ensure material integrity. Titanium powder feedstock complies with ASTM F2924 specifications for medical-grade Ti-6Al-4V used in powder bed fusion processes. Following printing, implants undergo standardized post-processing procedures including support removal, surface cleaning and finishing, stress-
