A robot dentist is carrying out successful autonomous implant surgery, fitting new teeth into patients in China. Although there are currently human medical staff present during the operations, they do not play an active role while it is being carried out. The implants are fitted to within a margin of error of 0.2-0.3mm, reaching the required standard for this kind of operation, experts said. The technology was designed to overcome mainland China’s shortage of qualified dentists and frequent surgical errors. The robot conducts the surgery by itself so it can avoid faults caused by human error. Moreover, the artificial teeth it implants are created by 3D printing.
