As reported by News, while medical staff still recognized the system in case of an emergency, they presented pre-programmed guidance to the robot.
Position orientation material was also fit to the patient’s mouth so that the robot could move in the conventional angles and depth. The robot was also registered to adjust to unexpected movements from the patient.
While the patient gained local anesthesia, she was alert for the entire hour-long system which was for dental implant surgery.
The news outlet cites that this is the first time an android was able to perform a procedure with no control or intervention from surgeons.
The feat has been the outcome of a collaboration for four years between the Fourth Military Medical University’s affiliated Stomatological Hospital, based in Xian, and the android institute at Beihang University in Beijing.
The improvement of the robot is a response to the shortage of qualified dentists, as well as to direct surgical errors that occur inland China, reports the News.
The technology was simulated by Wuhan University Stomatological Hospital and Beihang University’s robotics institute to deal with a lack of dentists in the country and frequent surgical errors.
The dental implants, made with 3D printing, were applied within a margin of error of 0.2-0.3 millimeters, the surgical model for this type of operation.
The patient was estimated using a CT scan and the robot was drafted with the specific movements it needed to conduct the surgery, including angles and depth for the new teeth. After a test, the procedure was executed on the woman in Xi’an, the capital of Shaanxi Province, who has inflicted only a local anesthetic. The robot was able to make improvements to compensate for the patient’s own movements.
