When most people think of orthodontic expanders, they imagine children or young teens. However, modern advancements in orthodontics have brought innovative solutions like the MARPE (Mini-Screw Assisted Rapid Palatal Expander) to the forefront, making it possible for adults to address issues like crossbites, crowding, and breathing problems effectively.

In this blog, we’ll explore how MARPE works, who it’s best suited for, its success rate, whether it causes pain, and what happens if it doesn’t work.

How MARPE Works

MARPE is a type of palatal expander specifically designed for adults whose palatal sutures (the seams in the roof of the mouth) have fused, typically after adolescence. Traditional expanders rely on the flexibility of these sutures, which diminishes with age. MARPE overcomes this limitation by using Temporary Anchorage Devices (TADs)—small titanium screws placed into the palatal bone.

These TADs anchor the expander securely, allowing controlled force to separate the palatal bones. This creates space in the upper jaw, correcting dental crowding, crossbites, and even improving nasal airflow. The process is non-surgical, although it may serve as a less invasive alternative to surgery in some cases.

Who Is MARPE For?

While MARPE is primarily designed for adults, it can also be effective in older teenagers whose palatal sutures are beginning to fuse. The ideal age group for MARPE is late teens to adults in their 20s and 30s. However, it has also been successfully used in older patients when the conditions are right.

Success Rate of MARPE

The success rate of MARPE depends on factors like the patient’s age, bone density, and the severity of their condition. Research shows that MARPE achieves its goals in 80-90% of cases when placed in the right candidates. Success rates are highest in patients with less severe palatal suture fusion.

For patients in their 40s or older, or for those with very dense bone, MARPE may be less effective, and alternative treatments, such as surgically assisted rapid palatal expansion (SARPE), may be considered.

Does MARPE Hurt?

Patients often worry about pain, but MARPE is generally well-tolerated. You may feel slight pressure or discomfort when the expander is first activated or during adjustments, but this usually subsides within a few days. Local anesthesia is used when placing the TADs, so the procedure itself is painless. Any post-procedure discomfort is typically mild and can be managed with over-the-counter pain relievers.

What Happens If MARPE Is Not Successful?

In cases where MARPE does not achieve the desired expansion, other options can be explored. The most common alternative is SARPE, which combines orthodontics with a minor surgical procedure to separate the palatal sutures.

Failure to expand with MARPE is rare when patients are properly selected. That’s why it’s crucial to work with an experienced orthodontist who can assess your unique needs and determine the best treatment plan.

Why MARPE Is Worth Considering

Aside from fixing crossbites and crowding, MARPE offers a significant benefit for many adults: improved nasal breathing. By widening the upper jaw, the nasal passages also expand, which can help alleviate breathing issues, reduce snoring, and enhance overall quality of life.
