The aim of MSE is to expand the maxillary arch, it does that by splitting by mid palatal suture and loosen up/breaking all pre maxillary sutures, such as zygomatic sutures and pterygomaxillary suture.

using micro-implant. The floor of maxillary palate is the floor of the nose when you increase the maxillary palate you increase the width of the nasal floor.

 

BENEFITS OF MSE (MAXILLARY SKELETAL EXPANDER)

 

  • MSE is considered mid face expander rather than maxillary arch expander, giving patient aesthetic pleasing facial proportion.
  • Widen narrow maxillary upper arch in teenager and even in adult.
  • Treatment of nasal blockage, snoring and sleep apnoea. MSE can increase the nasal air passage by widening the floor of nasal cavity.
  • Treatment of Posterior Cross Bite due to narrow maxillary arch.
  • Treatment of CIII skeletal malocclusion in conjunction with reverse pull headgear.
