The Maxillary Skeletal Expander (MSE) has evolved since 2004, and its applications have been steadily growing. With a proliferation of MSE related publications, there is clear evidence to support its utility in orthodontic therapy.

In his lecture, Dr. Moon will illustrate 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 MSE. Dental expansion, bone bending, and true skeletal expansion will be compared with these three treatment modalities. The adverse clinical consequences of RPE and SARPE in high-angle cases will be explored, and a new evidence-based approach in mitigating these problems by the use of MSE will be presented. Clinical cases involving non-surgical midfacial expansion in both adolescent and adult patients will be examined in detail, and optimal MSE fabrication and expansion protocols will be illustrated. Additional indications and uses of MSE including enlargement of narrow nasal airways and function as well as orthopedic correction of Class III combined with face mask (FM) treatment will also be presented. Finally, as yet unknown skeletal impact of MSE including changes in the facial dimension and surrounding structure will be demonstrated through clinical cases and 3D morphometrics.

In summary, this course will cover a comprehensive overview of current uses of MSE and will also provide more thought-provoking possibilities for those who are seeking more advanced applications of MSE.

Course Benefits:

  • Acquire knowledge in non-surgical expansion protocol using the bone-borne expander, and possibly reduce the number of invasive surgical procedures.
  • Understand the differences in expansion resulting from RPE, SARPE and micro-implant supported expander for use in patient-specific selection of expansion device.
  • Understand the positive consequences of skeletal expansion in patients with upper airway obstruction, and be able to work with the specialist in other disciplines (ENT, Sleep Medicine, etc.)
  • Comprehend novel concepts in Class III treatments in both growing and mature patients by combining MSE and face mask for effective Class III orthopedic correction.

Educational Objectives:

  • Improve obstructive nasal/pharyngeal airways with Maxillary Skeletal Expander (MSE)
  • Understand the expansion protocols based on skeletal maturity and biotype
  • Understand the stability of orthopedic transverse correction associated with various expanders

Intended Audience:
This course will be most beneficial for orthodontists, but many oral surgeons, ENT specialists and Sleep Medicine specialists have attended this course in the past.

Instructors:

Won Moon, DMD

Dr. Moon is serving as the chairman of the Section of Orthodontics, Program Director for an orthodontic residency program, the director of international affairs, and the Thomas R. Bales Endowed Chair in Orthodontics, 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 work has been published in various journals, not necessarily limited to orthodontics because of his background.
