Texas A&M: 3D Printed Bone the Future of Facial Surgery

Posted by Rebecca Partridge on Wed, Jan 11, 2017

Currently, doctors have two options when a patient needs a facial bone replaced due to injury or illness, such as cancer. They can take a bone from another part of the body and graft it into place. However, implant morbidity and complications caused by the trauma of multiple surgeries make this option less than ideal. The second option is to graft synthetic materials to the site. However, from time of injury to delivery of the custom implant takes about three to four weeks, which reduces the chances of the patient healing properly. But now a new technology being developed by researchers at Texas A&M’s College of Dentistry may revolutionize the treatment process.

In 3-D live printing, substances such as bioactive biopolymers are integrated with bioceramic materials. The material is then literally printed onto the affected area, thus forming a scaffolding rich in blood to assists new bone growth.

In an article for Texas A&M's research news, Venu Varanasi, assistant professor in the Department of Biomedical Sciences, their College of Dentistry, explains, “Our bioceramics are biodegradable... The intent in the end is to rapidly deliver the therapeutic, induce the healing at an earlier point, and then allow the cells and the tissue to overtake the material, consume the material, and allow for full restoration of natural bone.”

Varanasi’s process has had promising results in animal models. The chemical make up of the new bone has proved to be comparable to the bone in the surrounding area. Researchers in Varanasi’s lab can complete the entire printing process within 45 minutes. In the future 3-D bone printing could give oral and maxillofacial surgeons a better option for reconstructing facial defects.

Dr. Likith Reddy, associate professor in oral and maxillofacial surgery and director of residency training at Texas A&M University College of Dentistry, says that, “The gold standard for reconstruction of such defects involves carving of the cranial bone, hip bone or the leg bone to recreate the missing structures. This is technically impossible for large facial defects.” Dr. Reddy believes that if this technology works as anticipated, “Reconstruction of such complex facial bony defects would become less of an art and more of a science.” According to Reddy, in vivo printing holds the potential for substantial strides in patient rehabilitation.   

Dr. Varanasi’s hope is to apply 3-D printing to other parts of the body as well. “That’s the holy grail,” Varanasi says. “You can just take off-the-shelf components in the OR, print them directly into the bone defect, and the patient’s own bone is doing the healing. There are a lot of possibilities. That’s the beautiful thing about it.”

This research is currently funded by the National Institutes of Health-National Institute of Dental and Craniofacial Research and Texas A&M University intramural grants.  To help advance this technology to that next level, Varanasi and the Texas A&M Office of Technology Commercialization have been in talks with potential investors. Research grants with National Institutes of Health, National Science Foundation, the Department of Defense are also being pursued. Meanwhile, researchers at the College of Dentistry continue to develop the technology to enhance reproducibility.
