Clinical Advisor
DR. Kee-Joon Lee
Professor Keejoon Lee is a highly distinguished faculty member and leading clinical researcher in the Department of Orthodontics at Yonsei University College of Dentistry. Renowned globally for his contributions to advanced orthodontics, his academic and clinical focus centers heavily on biomechanics, innovative therapeutic procedures, and complex multi-disciplinary treatments. A significant portion of his landmark work revolves around pioneering techniques in bone-anchored maxillary expansion and non-surgical approaches to severe skeletal discrepancies, providing alternatives to conventional orthognathic surgery for complex patient cases. His extensive research portfolio spans over 150 peer-reviewed scientific publications, establishing him as a foremost authority in dental materials and advanced digital orthodontics.
His recent investigations heavily feature the evolution of 3D-printed clear aligner technology, focusing closely on the material's surface topography, hardness, and biological safety. Additionally, Professor Lee is at the forefront of incorporating modern diagnostic imaging into orthodontic planning, publishing critical studies on the accuracy and error reduction of 3D landmark annotations using cone-beam computed tomography (CBCT). Beyond material science and digital technology, his clinical research addresses some of the most challenging scenarios in modern dentistry. He frequently publishes case studies and clinical trials on treating adult patients presenting with skeletal class III malocclusions coupled with severe alveolar bone loss. Through his focus on specialized tooth movement and advanced biomechanical anchorage, his work consistently demonstrates how strategic orthodontic management can be used to successfully preserve and rehabilitate periodontally compromised teeth.
