Children usually have excellent bone growth. “Implants would be quickly replaced with their own bone, which would grow as the child grows,” he said.

The technology also has narrow holes running through the artificial bones, inviting blood vessels and cells to come and help regenerate bone.

The research team is also working on a second-generation CT Bone, which contains materials that facilitate bridging between the artificial and real bone.

Experiments with implanting it in the skulls of Beagle dogs are underway with good results, he said. The ultimate goal is to be able to construct bone from the living cells of patients, allowing them to take in larger pieces.
