For older teens and adults with a narrow upper jaw, traditional palatal expanders often aren't effective because the midpalatal suture has fused. The Maxillary Skeletal Expander (MSE) offers a groundbreaking solution. At Bar Orthodontics in Rockwall, TX, Dr. Bar uses MSE technology to achieve true skeletal expansion—often avoiding the need for invasive surgical procedures.

The Maxillary Skeletal Expander (MSE) is an advanced orthodontic appliance that uses four small temporary implants (TADs) anchored directly into the palatal bone.

Unlike traditional expanders that push on teeth, the MSE applies expansion force directly to the bone, allowing it to separate the fused midpalatal suture in older patients.

This bone-borne approach makes true skeletal expansion possible for patients who were previously told surgery was their only option.

MSE is ideal for:

• Teens (typically 14+) whose palatal sutures have begun fusing
• Adults of any age with narrow upper jaws
• Patients with crossbites who want to avoid surgery
• Those with breathing issues related to a narrow palate
• Patients with sleep apnea who may benefit from expanded airways
• Anyone seeking a non-surgical alternative to SARPE (Surgically Assisted Rapid Palatal Expansion)

The MSE procedure involves:

1. Placement of four mini-implants into the palatal bone (under local anesthesia)
2. Attachment of the MSE appliance to these implants
3. Daily activation with a special key, similar to traditional expanders
4. Gradual separation of the midpalatal suture over 2-4 weeks
5. Stabilization period while new bone fills the expanded area
6. Removal of the appliance once expansion is complete and stable

The direct bone anchorage allows the MSE to generate enough force to split the fused suture without relying on tooth movement.

Traditional Expanders:

• Rely on teeth for anchorage
• May tip teeth rather than expand bone
• Ineffective after suture fusion

MSE:

• Anchored directly to bone
• Achieves true skeletal expansion
• Effective even in fully mature adults

For patients over 14-16 years old, MSE typically produces better, more stable results with fewer dental side effects.

Patients who undergo MSE expansion often experience:

• True skeletal expansion of the upper jaw
• Improved nasal breathing and airway capacity
• Correction of crossbite without surgery
• More space for crowded teeth
• Broader, more aesthetic smile
• Potential improvement in sleep-disordered breathing
• Stable, long-lasting results
• Avoidance of invasive surgical procedures

MSE treatment typically takes 4-6 months total:

• Mini-implant placement takes about 30 minutes
• Active expansion phase lasts 2-4 weeks with daily turns
• You may feel pressure across the palate and nose during expansion
• A gap between front teeth is normal and expected—it will close
• Stabilization phase allows new bone to form (3-4 months)
• The appliance is then removed, and orthodontic treatment continues

If you've been told you need surgery to correct a narrow jaw, contact Bar Orthodontics for a second opinion. MSE may offer a less invasive path to the results you're looking for.
