The MSE has evolved since 2004, and its application has been steadily growing globally. With a proliferation of MSE related publications by multiple authors, there is clear evidence to support its impact.
The dental and skeletal effects of maxillary expansion using the conventional rapid palatal expander (RPE), the surgically-assisted rapid palatal expander (SARPE), and the micro-implant assisted midfacial skeletal expander (MSE) will be illustrated. Clinical cases involving non-surgical midfacial expansion in both adolescent and adult patients will be examined in detail. Through these clinical examples, a proper MSE fabrication and expansion protocols will be illustrated.
Many patients requiring maxillary expansion often have narrow nasal airways, and positive changes in nasal airway with application of MSE are common. Clinical cases and research findings illustrating the profound enlargement of nasal airways and functional improvements, MSE can also aid in orthopedic correction of Class III cases when combined with a face-mask (FM). Clinical cases combining MSE and FM in both growing and mature patients will be discussed, and orthopedic effects will be illustrated.
Lastly, unknown skeletal impacts will be further explored. Changes in the facial dimension and surrounding structure will be demonstrated through clinical cases. The latest findings from the UCLA research team will be presented in order to enhance depth of understanding in impact of MSE.
Course instruction by Prof. Won Moon
Dr. Won Moon is the Thomas R. Bales Endowed Chair in orthodontic residency program at UCLA School of Dentistry. 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 utilising surface mapping functions and Elliptical Fourier's Descriptors, Finite Element Model (FEM) Development and Simulation, and other quantitative methods. His work has been published in various journals, and he is also co-author of three textbooks. He has presented these findings in 33 countries, totalling over 400 presentations.
His interest in mid-facial expansion began in 2004 as micro-implant became available in USA, 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.
