Introduction Video of MSE

MSE is indicated in the treatment of posterior cross bite, Class III malocclusions and it is able to improve nasal airflow and breathing. Recent publications show the positive effects also in the therapy of Obstructive Sleep Apnea (OSA).

The main difference between
The MSE and Others.

" The Maxillary Skeletal Expander (M.S.E.) can effect both dental and skeletal expansion.The adverse clinical consequences of RPE and SARPE in high-angle cases will be get solved by M.S.E. Also, many patients who requiring maxillary expansion often have narrow nasal airways, and positive changes in nasal airway with application of M.S.E. are common. "

Benefits & Contraindications

Benefits

Mostly Skeletal Expansion: less bone bending and dental tipping compared to RPE and surgically assisted maxillary expansion (SARPE)
Less invasive than SARPE and Orthognathic Surgery
Significant increase in upper airway volume: nasal obstruction, sleep apnea
MSE causes expansion of the surrounding structures
Vertical control in high angle cases
FM and MSE for Class III correction
MSE can be used for mature patients

Contraindications

Extremely narrow palatal vault
Patients with previous mid-facial trauma
Extremely thick/dense palatal bone and/or dense buttress bone
Extremely thin palate with low bone density

Components of MSE

MSE Expander (Available expansion sizes: 8mm, 10mm & 12mm)
- Choose an expander size according to a width of patient's palatal vault 􀀢
Micro lmplant(M.I) (01.8mm X 11mm & 13mm Lengths are available)
- Choose M.I length according to the thickness of patient's palatal bone
  - *For MSE type 1, M.I is 01.5mm and for MSE type 2, M.I is 01.8mm
2 Activation Keys (1 Short & 1 Long)
Mini Hand Driver
- Use with initial insertion of M.I placement
  
  The best way is to use Mini Hand Driver for initial
Ratchet Wrench Driver
- Inserting and Removing M.I
Short Engine Blade (Shaft)
- Attach to Mini Hand Driver (J)
Safety Leashes
- With ® activation key
