Maxillary Skeletal Expansion (MSE) is an advanced orthodontic technique designed to widen the upper jaw at the skeletal level. Unlike conventional expanders that primarily move teeth, MSE works by directly expanding the palatal bone using temporary anchorage devices (TADs). This makes it an effective option for both adolescents and adults seeking non-surgical jaw expansion. At Mars Orthodontics, we use the latest digital technology to ensure precise, evidence-based results tailored to your unique needs.

Is Maxillary Skeletal Expansion (MSE) Right for You?

MSE may be suitable if you have:

• A narrow upper jaw, causing crowding, crossbites, or bite issues
• A high-arched palate that affects proper tooth alignment
• Jaw size mismatch impacting bite function and facial balance
• Skeletal discrepancies requiring expansion beyond traditional orthodontics

At Mars Orthodontics, we perform a thorough assessment, including advanced 3D imaging, to determine if MSE is the right option for you.

How Does MSE Work? Step-by-Step Guide

1. Comprehensive Evaluation – We conduct a CBCT scan and digital imaging to assess jaw structure and expansion potential.
2. Custom Expander Placement – The MSE appliance is anchored with TADs in the palatal suture to ensure stable skeletal movement.
3. Gradual Expansion Process – Patients adjust the device over time, following our guidance, to stimulate controlled widening of the jaw.
4. Retention & Orthodontic Alignment – Once expansion is achieved, the jaw stabilizes, allowing for final alignment with braces or aligners to optimize bite function and aesthetics.

What to Expect: The Midline Gap

One of the most noticeable changes during MSE treatment is the temporary gap that may form between the upper front teeth.

Temporary midline diastema during MSE treatment: This image shows the characteristic gap between upper central incisors that develops during active expansion. This space is a positive indicator that skeletal expansion is occurring at the midpalatal suture. At Mars Orthodontics, we explain to patients that this temporary gap is an expected part of successful MSE treatment and will be closed using braces or aligners following the expansion phase.

Why does MSE create a gap?
As the upper jaw expands, the natural connection between the two halves of the palate separates slightly, leading to a space between the front teeth. This is a normal and positive sign that skeletal expansion is occurring correctly.

Will the gap close on its own?
Unlike some orthodontic treatments, the gap from MSE typically requires orthodontic intervention to close completely. Once expansion is achieved, braces or aligners will be used to bring the front teeth back together, creating a seamless smile.

How long does gap closure take?
Research suggests that gap closure after MSE typically takes 6-8 months with orthodontic treatment. However, individual factors such as age, bone density, and biological response can influence this timeframe. At Mars Orthodontics, we closely monitor your progress and adjust your treatment plan as needed.

MSE vs. Palatal Expanders: Which One is Better?

Traditional expanders primarily move teeth, while MSE expands the jaw itself. MSE’s bone-anchored design provides a more stable, predictable outcome, making it ideal for non-growing patients and reducing the risk of relapse.

Scientific Insights: MSE and Airway Improvement

Some research suggests that MSE may contribute to increased airway volume and improved nasal airflow, potentially benefiting patients with airway constriction.* However, these outcomes vary among individuals and should not be considered a guaranteed solution for all breathing concerns. At Mars Orthodontics, we assess each case individually to determine the potential benefits of MSE based on the latest scientific findings.

Understanding the Risks and Considerations

All orthodontic treatments carry some risks. With MSE, patients may experience:

• Mild pressure or discomfort during activation
• Temporary speech changes as the tongue adapts to the appliance
• Possible TAD loosening, which may require minor adjustments
