Scientists have recently printed a highly elastic biomaterial 3D into artificial bones, successfully stimulating the animal to damage the spine and the skull to generate new bones and repair the wound. This technology is expected to be tested in humans within 5 years, and personalized bone grafting is just around the corner.
The Northwestern University research team published a report on the biomaterial "Hyper-Elastic Bone" (HB) in Science Translational Medicine. According to the report, “superelastic bones†are mostly made of ceramics, containing minerals and polymers found in teeth and bones. Unlike bone grafts that are generally expensive, too fragile, difficult to mold, and fear of rejection, "super-elastic bones" are inexpensive, can print many shapes, and are cut, folded, joined, elastic, and tough, as needed. The room can also be used simply and quickly.
The research team transplanted “super-elastic bones†into the injured spine of mice, and found that “super-elastic bones†quickly merged with surrounding cell tissue to regenerate bones, thus promoting the fusion of rat spine. This result is quite impressive.
Subsequently, the team printed a larger piece of bone and repaired a macaque's skull hole. After 4 weeks, the macaques recovered and there were no signs of infection or side effects, and new bone growth was evident.
Researchers hope to use this artificial bone in spinal, dental, reconstruction, and bone cancer surgery to provide tailor-made bone grafts for patients.
