• 3D-Printed Piezoelectric Tooth Implant Restores Chewing Sensation in 90% of Trial Patients July 6
Additional Context
Scientists in China have developed a 3D-printed tooth implant that restores the sense of chewing — a capability that conventional dental implants don’t offer — with 90% of trial patients reporting recovered masticatory perception after receiving the device.
The implant, developed by researchers at Huazhong University of Science and Technology, uses piezoelectric materials to convert the mechanical forces of chewing into electrical signals, which are then sent to the brain via the tooth nerve. The core is made from barium calcium zirconate, a material known to be safe for humans, and is surrounded by a 3D-printed ceramic crown that mimics natural tooth enamel. Both components are customized and assembled to match the exact size and shape required for each patient.
The clinical problem the
