Researchers at the Krakow University of Technology are pioneering a bioactive material for 3D-printing bone implants tailored to individual patient needs, especially for facial and cranial bones. The project, led by Dagmara Słota, aims to create implants resembling natural bone tissue, stimulating bone-forming cells for regeneration.
Current Challenges in Bone Reconstruction
Traditional bone grafts involve autogenous or allogeneic transplants, presenting drawbacks such as aesthetic concerns or immunological complications. Commercial metallic implants pose corrosion risks, and personalized metal implants are costly due to the need for unique molds.
Innovative Material for 3D Printing
The team is developing a bioactive material for 3D printing, ensuring strength, porosity for blood vessel ingrowth, and a composition mimicking natural bone. The focus initially lies on facial bone implants, considering both aesthetic and functional aspects.
Advantages of 3D-Printed Implants
Słota envisions faster procedures with personalized 3D-printed implants, shortening patient wait times. The 3D printing process involves imaging the bone defect, printing the implant, and conducting surgery in a matter of days. This approach aims to accelerate patient recovery through enhanced bone cell stimulation.
The Future of Regenerative Implants
While personalized 3D-printed implants are not entirely new, Słota’s team is pushing boundaries with a unique material composition designed for bioactivity. The implant, based on modified polymers, remains confidential to the market, promising advancements in regenerative processes.
