A new technique allows to create 3D custom bone implants to measure. The implants fuse with the original bone until they degrade completely.
Danish company Particle3D is revolutionizing the lives of patients in need of reconstructive surgery. A pioneer in the field, the company is using a new method for the 3D printing of light and personalized bone implants that merge with the skeleton until it slowly disappears.
Typically, implants are made from non-degradable materials, such as polymer or titanium. This new alternative offers a lower risk of infection and may even be used in astronauts traveling to space, writes the SingularityHub.
The process used by Particle 3D begins with an x-ray of the patient's bones. Subsequently, the data is inserted into a computer program that allows to optimize the implant design. Finally, the implant is personalized, printed and sent by the Danish company to the respective hospital.
The implants created with this technique are porous, which allows the bones to grow naturally, with the implant degrading over time. Tests on pigs and rats were successful and showed that blood vessels and bone marrow developed in the implants as early as eight weeks later.
3D printing has been quite beneficial in healthcare. Surgeons can view and practice with 3D models of bones, body parts and organs before an operation.
The advantages of this innovation include lower costs, the possibility of customization, shorter time to market and distributed production.
