I was recently reminded about this technological advancement! Epithelial cells are part of the Periodontum, which includes the Periodontal Ligament. Being able to print these biological materials (and a scaffold) opens up new possibilities in functionality for regenerative and prosthetic products.
How far away could a 3D printed gingiva implant be? Hazard a guess in the comments!
