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 UCLA 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
  • Differences between various designs of micro-implant assisted rapid palatal expanders (MARPE), and MSE (a particular type of MARPE)
  • How to produce parallel expansion of maxilla in occlusal and frontal planes with MSE
  • Indications for the use of MSE in children and nonsurgical orthopedic expansion in adults with MSE
  • Stability of orthopedic transverse correction
  • Proper fabrication of MSE and expansion protocols based on skeletal maturity and biotype
  • Orthopedic protraction in Class III cases with MSE and FM
  • Improving an obstructive nasal/pharyngeal airway with MSE
  • Proper fabrication of MSE and Expansion protocols based on skeletal maturity & biotype
  • Contraindications
  • Overcoming difficult cases and troubleshooting
  • Digital Workflow and MSE Customization
  • Future direction in utilization of MSE
Hands-on Workshop

This workshop is for those who previously took the basic MSE course and want a hands-on experience.

  • OverviewOverview of MSE fabrication and clinical tips through case studies
  • Proper placement of MSE and contouring of the supporting arms on the typodont
  • Inserting Micro-Implants into the synthetic bone using both the mini-hand-driver and Ratchet Wrench
  • MSE Activation
  • Removing Micro-Implants with the mini hand driver
