The Maxillary Skeletal Expander (MSE), unique micro-implant assisted rapid palatal expander (MARPE), has evolved since 2004, and its application has been steadily growing globally. With a proliferation of MSE related publications by multiple researchers, there is clear evidence to support its impact on craniofacial structures surrounding the maxillary complex. With this concept of orthopedic expansion, MSE can also aid in orthopedic correction of Class III cases when combined with a face-mask (FM) and other protraction devices. Clinical cases combining MSE and FM in both growing and mature patients will be discussed, and orthopedic effects will be illustrated. The use of growth modification for young patients and distraction-like protraction techniques for mature patients, in conjunction with this new device, open the door to many new non-surgical possibilities. The latest findings from the research team will be presented in order to enhance depth of understanding in impact of MSE for Class III treatments, particularly with mature patients. Some groundbreaking possibilities will be presented in detail through clinical cases.
Learning Objectives:
After this session, attendees will be able to:
Outline the difference between the traditional "tooth-borne" and "bone-borne" expansion and protraction, in terms of adverse dento-alveolar side effects, magnitude of orthopedic changes, optimal force, etc.
Understand that MSE causes orthopedic expansion and profound disarticulation of the perimaxillary sutures in both children and adults, which aid in protraction of midfacial structures when combined with a protraction device.
Outline the difference between growth modification technique for children and distraction-like protraction for mature patients, and clinically accommodate for the differences, in terms of required forces, FM duration, etc.
