About

K. Ohtsuki is a pioneering researcher at the intersection of robotics and dental rehabilitation, with a body of work that has fundamentally advanced the field of dental robotics and jaw movement therapy. Best known for developing sophisticated 6-degrees-of-freedom (6-DOF) parallel robot systems designed to assist patients suffering from temporomandibular joint (TMJ) disorders and related jaw dysfunctions, Ohtsuki's research has transformed traditionally subjective, experience-dependent therapies into quantifiable, reproducible clinical procedures. Among Ohtsuki's most influential contributions is the development of integrated dental robot systems that simultaneously model both the patient and the clinician — a dual-model framework that brought unprecedented precision to mouth opening and closing training, accumulating over 50 citations apiece. Equally notable is pioneering work on mastication robots capable of quantifying masticatory efficiency, cited nearly 50 times, which established a mechanical basis for evaluating human chewing performance. Ohtsuki also extended clinical applications to lateral jaw movement training and intermaxillary traction therapy, while exploring remote robotic treatment delivery across distances of 120 km — remarkably forward-thinking work for its era. With a cumulative citation count exceeding 230, Ohtsuki's research remains an essential reference for engineers and clinicians advancing rehabilitative dental robotics.
