A research team at Northwestern University in Evanston, Ill., has developed a 3-D synthetic bone implant ink to be used in 3-D printers. The biomaterial in the ink creates an implant that not only acts as a synthetic bone, but also induces bone growth and regeneration.
Here's what you need to know:
1. The biomaterial is made with hydroxyapatite (a calcium mineral found in human bone, which induces bone regeneration) and a biodegradable polymer.
2. Physicians are able to scan the patient's body to 3-D print an individualized implant. The implant would also be able to be trimmed during the procedure, due to the elasticity of the product.
3. The researchers have been able to add other substances to the ink, such as antibiotics that would reduce the risk of postoperative infection.
4. The researchers hope that this development will help pediatric patients with bone defects. At present, it is difficult for children to receive permanent implants, since their bodies continue to grow.
While research on the product is ongoing, the synthetic bone implant ink has shown successful results in two animal models.
