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 after MSE in both adolescent and adult patients will be closely evaluated. Furthermore, 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 research team will be presented in order to enhance depth of understanding in impact of MSE.

Lecture Learning Objectives

  • Differences in expansion by RPE, SARPE, MARPE and MSE

  • Nonsurgical orthopedic expansion in adults with MSE
  • Stability of orthopedic transverse correction
  • Proper fabrication of MSE and optimal activation protocol based on mechanical and biological considerations
  • Craniofacial structural changes with MSE
  • Orthopedic protraction in Class III cases
  • Improving an obstructive nasal/pharyngeal airway with MSE
  • Contraindications and troubleshooting
  • Overcoming difficult cases
  • Combining minor surgical procedure with MSE
