Exploring 3D Printed Implants With Anti-Dropout Function to Overcome Time Constraints in Acute Orbital Fractures for Patient-Specific Implants

Dong Ha Park et al. investigated rapid production of 3D-printed patient-specific implants using AVIEW software and bioactive materials (BGS-7/PCL) for orbital fracture reconstruction. The implants featured unique anti-dropout locking designs to address issues like dislocation and post-surgical implant misalignment. Using 3D printing reduced production times to 4.6 days. Involving 12 patients, they evaluated outcomes via CT scans pre- and post-surgery. Results revealed precise restoration of orbital volumes (<0.1 mL deviation) and reduction of exophthalmos (<1 mm for most). The study highlighted significant improvements over conventional methods, minimizing complications and surgical duration. Limitations included a small sample size and lack of a control group. Future directions suggest broader testing and material enhancements. This research demonstrates a groundbreaking use of rapid 3D-printed implants in acute trauma settings, contributing significantly to personalized medicine.
