Benefits & Contraindications

Benefits
  • Vertical Control in High Angle Cases
  • Significant Increase in Upper Airway Volume: Nasal Obstruction, Sleep Apnea
  • Mostly Skeletal Expansion: Less Bone Bending and Dental Tipping Compared to RPE and SARPE
  • Less Invasive than SARPE and Orthognathic Surgery
  • FM and MSE for Class III Correction
  • MSE Causes Expansion of the Surrounding Structures
  • MSE Can Be Used for Mature Patients

Contraindications

  • Extremely narrow palatal vault
  • Patients with previous mid-facial trauma
