If you have a narrow upper jaw, crowding, or a crossbite, jaw expansion may be the missing step before braces or clear aligners. At Elite Orthodontics Group in San Diego, we use modern expansion techniques to create space, improve bite alignment, and support long-term stability.
What Is MARPE Treatment?
MARPE stands for Miniscrew-Assisted Rapid Palatal Expansion. It is an orthodontic appliance that widens the upper jaw using small temporary anchor screws (miniscrews). This helps achieve greater skeletal expansion than traditional expanders, which mainly expand the tips of teeth.
Who Is It For?
This option is often recommended for:
- Older teens whose jaw growth is more developed
- Adults who still need upper jaw expansion
- Patients who are not ideal candidates for a traditional childhood expander
What Can It Help Correct?
Expansion may support treatment for common problems, such as:
- Crossbite correction
- Crowding caused by a narrow upper jaw
- Bite imbalance that affects chewing
- Jaw alignment treatment when the upper and lower arches do not match well
- Creating space to support teeth straightening options without extractions, in some cases
How Does It Work?
During treatment:
- The appliance is placed in the upper arch
- A small activation key is used to widen the device gradually
- Expansion occurs in a controlled way over time
- A stabilization phase follows, so the jaw can adapt
Many patients then continue with braces or clear aligners to refine tooth alignment and bite fit.
What Does It Feel Like?
Most patients notice pressure or tightness during activation, especially early on. This is normal and typically improves as your mouth adjusts. Our team will walk you through comfort tips and what to expect.
How Long Does Treatment Take?
The timeline depends on your goals and anatomy, but it usually includes:
- A short active expansion period (often measured in weeks)
- A longer stabilization period
- Follow-up orthodontic treatment as needed (braces or clear aligners)
How Is This Different From Braces or Clear Aligners?
Braces and clear aligners primarily move teeth. Jaw expansion focuses on widening the upper jaw itself, which can improve how your bite fits and create room that tooth movement alone cannot always achieve.
