Can Glass Replace Bone? Chinese Scientists 3D-Print Bone-like Bioglass

Healthcare, Medicine /

Chinese researchers have developed 3D-printed bioglass that matches bone strength, supports cell survival for weeks, and could transform customized dental implants. Glass is rarely thought of as a replacement for human bone, but Chinese scientists suggest it may be possible. They have created a bioactive, 3D-printable glass that replicates bone strength. Tests showed it supports […]
