Dr. Won Moon is the Founder/CEO of the Moon Principles Institute (“the MoonLab”) and a Co founder/Chief Innovations Officer of BioTech Innovations. He served as the Thomas R. Bales  Endowed Chair in Orthodontics for the orthodontic residency program at UCLA School of Dentistry  (2013-2020), and he currently holds two academic positions: Full-Professorship at Ajou University  School of Medicine, and Adjunct Professorship at the Forsyth Institute. He has been a Diplomate of the American Board of Orthodontics since 2002. He completed his dental education at Harvard and  orthodontic education at UCLA. He studied mathematics prior to dentistry, and his research topics  include 3D image analysis utilizing surface mapping functions and Elliptical Fourier’s Descriptors,  Genomewide Association Study of Craniofacial Phenotypes, Finite Element Model (FEM)  Development and Simulation, Applications of 3D Printing in Orthodontics, Orthopedic Correction,  Airway Changes with Orthopedic Corrections, Accelerated Tooth Movement, Micro-implant (MI)  Design study, Digital Workflow, and Aligner System Development. His work has been published in  various journals, not necessarily limited to orthodontics because of his physical science background,  and he is a co-author of six textbooks. He has presented these findings in 42 countries, totaling over  500 presentations. He received multiple research grants during his tenure at UCLA, including the  Groundbreaking Research Project Grant Award in 2014. Besides the numerous research and  presentation awards over the years, he has received the “Faculty of the Year Award” multiple times at UCLA Orthodontic Program, and he was the recipient of the “Lifetime Achievement and Faculty  Dedication/Excellence Award” in 2019. His current focus has been establishing protocols for  orthopedic corrections with MI, improving the airway for patients with nasal obstruction, creating  virtual patients utilizing image analysis and FEM, and developing a novel Moon Aligner System. 

His interest in aligner systems began in 2010 as the aligner systems became popular, but they had  countless shortcomings and could not achieve optimal orthodontic results. He has won the Center  Award Grant from the American Association of Orthodontic Foundation (AAOF) in 2018 as a Co-PI of  the research project, “Standard Characterization of Clear Orthodontic Aligner”, and the goal of the  project was to develop protocols that can be used to evaluate the mechanical properties of clear  aligners. He was also invited as a keynote speaker for the Congress of the Spanish Society of Aligners (SEDA) and National Congress of Italian Aligner Society (SIALIGN) in 2021. He is currently involved  in multiple aligner research projects in collaboration with national and international colleagues. He  holds multiple patents, three of which are aligner related, and more patents are on the way.  

His interest in mid-facial expansion began in 2004 as micro-implant became available in the USA, and  he is responsible for developing Maxillary Skeletal Expander (MSE), a unique micro-implant assisted  rapid palatal expander (MARPE). He has been active in advocating non-surgical skeletal expansion in  both children and adult patients, especially for those who may suffer from airway restrictions. His  presentation in MSE has been widely accepted internationally, and numerous peer-reviewed  publications are available.
