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 maxillary skeletal expander (MSE) will be illustrated. Clinical cases involving nonsurgical 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. Secondly, other advantages of utilizing MSE will be demonstrated. 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, the 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.

This course will cover a comprehensive overview of current usage of MSE and will also provide more thought-provoking possibilities for those who are seeking more advanced applications of MSE, suggested by the latest findings from the UCLA research team
