About

Peijun Lyu is a pioneering dental researcher whose work sits at the intersection of robotics, laser technology, and clinical dentistry, with a particular focus on revolutionizing tooth preparation techniques. His most significant contribution has been the development and validation of an automatic tooth preparation system that harnesses ultrashort pulse laser (USPL) technology — including femtosecond and picosecond lasers — controlled by precision robotic devices and three-dimensional motion planning software. This innovative approach directly addresses the limitations of traditional manual tooth preparation, offering enhanced accuracy, consistency, and clinical efficacy. Lyu's most cited work, a 2016 preliminary study with 38 citations, established the foundational feasibility of this automated technique, while subsequent research refined critical parameters such as cutting depth, taper control, and heat regulation in confined spaces — the latter being a crucial patient safety consideration. His 2019 study on robotic ultrashort pulse laser systems further cemented this body of work with 20 citations. Beyond technical development, Lyu has contributed broader perspectives through his review of dental robotics history and future directions. Collectively, his research has garnered nearly 100 citations, marking him as a leading voice in the emerging field of robotic-assisted dentistry.
