MARPE
Mini-implant Assisted Rapid Palatal Expansion for Teens & Adults
Revolutionary Jaw Expansion Without Surgery
For decades, adults needing jaw expansion were told they'd need surgery. MARPE (Micro-implant Assisted Rapid Palatal Expansion) has changed everything. This innovative technique uses mini-implants to widen the upper jaw—non-surgically—creating space, correcting crossbites, and improving airway even after the jaw has stopped growing.
Why It's a Game-Changer: MARPE makes true skeletal expansion possible for older teens and adults—avoiding surgery, saving time and cost, and delivering stable, long-term results. It's one of the most exciting advances in modern orthodontics!
What It Is
MARPE (Micro-implant Assisted Rapid Palatal Expander) is an advanced expansion technique that uses mini-implants to widen the upper jaw in teens and adults—something once thought impossible without surgery.
How It Works
Four tiny implants placed in the palate provide stable anchorage to split the midpalatal suture and widen the jaw, creating space and improving airway—even after the suture has fused.
Why It's Revolutionary
MARPE makes jaw expansion possible for adults who would otherwise need jaw surgery, offering a non-surgical solution for crowding, crossbites, and airway restrictions.
Who Benefits from MARPE?
Common scenarios where MARPE is the ideal solution
Teens & Adults with Narrow Jaws
If your palate is narrow and your midpalatal suture has fused (typically after age 16), traditional expanders won't work—but MARPE can!
Large Gaps from Extractions
When closing extraction spaces, TADs prevent back teeth from moving forward—keeping them anchored while front teeth slide back.
Avoiding Headgear
TADs eliminate the need for traditional headgear—no bulky appliances or compliance issues!

From placement to removal—demystifying the entire process
Closing Extraction Spaces
1 visit
We take 3D scans (CBCT) to assess your palatal suture, bone structure, and airway. We'll determine if MARPE is right for you.
What Happens:
Custom MARPE Fabrication
2-3 Weeks
Your MARPE appliance is custom-designed based on your scans and sent to a specialized lab for fabrication.
What Happens:
Placement of Mini-Implants
1 visit (60-90 min)
Under local anesthetic, we place four small mini-implants into your palate. This is similar to getting a filling—minimal discomfort!
What Happens:
Expansion Phase
3-6 weeks
You (or a helper) turn the expansion screw daily using a special key. You'll feel pressure as the suture gradually splits and the jaw widens.
What Happens:
Stabilization Phase
6-9 months
Expansion stops, but the appliance stays in place while new bone fills the gap. This is critical for long-term stability!
What Happens:
Removal & Continued Orthodontics
Ongoing
Once the bone has solidified, we remove the MARPE. If you're in braces or aligners, we continue aligning your teeth into the new, wider jaw.

Tips for Successful Expansion
Make your MARPE experience smooth and effective
Follow the Turning Schedule
Turn the screw exactly as prescribed—usually 1-2 times per day. Consistency is key to achieving the right amount of expansion.
Turn Toward the Back of the Throat
Always rotate the key toward the back of your throat until the next hole appears. Never turn backward!
Use Good Lighting
Use a flashlight or phone light to clearly see the screw hole. Good visibility prevents mistakes.
The Gap is a Good Sign!
As a gap appears between your front teeth, it means the expansion is working! This gap will close naturally with braces.
Manage Pressure with OTC Pain Relief
Feeling pressure for 10-15 minutes after each turn is normal. OTC pain reliever can help if needed.
Keep It Clean
Brush around the MARPE after every meal. Use a water flosser to flush debris from under the appliance.
The MARPE Advantage
Why MARPE is transforming orthodontic treatment
Non-Surgical Jaw Expansion
Achieve results that would otherwise require surgery—without the scalpel, anesthesia, or recovery time.
Improved Airway & Breathing
Widening the upper jaw increases nasal airway volume, potentially reducing or eliminating sleep apnea and snoring.
True Skeletal Expansion
Force is applied to bone (not teeth), resulting in true skeletal widening—stable and predictable.
Avoid Tooth Extractions
Creating space naturally means fewer cases requiring permanent tooth removal to fit crowded smiles.
Correct Crossbites
MARPE effectively corrects posterior crossbites, improving bite function and facial symmetry.
Enhanced Facial Aesthetics
Expansion can improve facial width and proportions, creating a more balanced, attractive appearance.

MARPE Success Stories
Real results from real patients
Adult with Severe Crowding
MARPE created the space needed to align teeth without extractions—preserving the natural smile.
Crossbite Correction
MARPE widened the upper jaw to match the lower, correcting the crossbite and improving bite function.
Sleep Apnea Improvement
Expansion increased nasal airway volume, reducing apnea episodes and eliminating the need for CPAP in some cases.
Avoiding Jaw Surgery
MARPE provided the expansion needed to avoid surgical jaw widening—saving time, cost, and recovery.
