The rise of 3D printing in surgical planning and implant design has allowed for greater customization and precision in modern surgery. Surgeons now use 3D-printed models to simulate complex procedures, gaining better understanding of patient-specific anatomy before operating. This technology also allows for the creation of patient-tailored implants, prosthetics, and even anatomical scaffolds for tissue regeneration. In orthopedics, maxillofacial surgery, and reconstructive procedures, 3D printing has enabled the development of more precise, personalized implants that better fit the unique geometry of each patient’s body. Surgeons can now perform preoperative planning using detailed, patient-specific replicas of tissues and organs, enhancing outcomes while reducing operative time and risk. As the technology matures, 3D printing is expected to further revolutionize surgical fields, making surgeries more effective, less invasive, and more patient-centered.
