Non-Surgical Palatal Expansion for Teens and Adults in Arvada, CO
MARPE stands for miniscrew-assisted rapid palatal expansion. It is the reason an adult in Arvada with a narrow upper jaw no longer has to choose between jaw surgery and living with the problem.
A traditional expander pushes against the teeth and depends on the midpalatal suture — the seam running down the roof of the mouth — still being open. That seam typically fuses somewhere between ages 12 and 15. MARPE anchors directly into the bone of the palate with several small titanium miniscrews (TADs), so the expansion force is applied to the skeleton rather than borrowed from the teeth. That single change is what makes real widening possible in patients whose suture has already closed.
Dr. Michael Berger, a member of the American Association of Orthodontists, plans and places these cases personally at our Arvada practice.
Who MARPE Is For
We evaluate patients for MARPE when the upper jaw is too narrow for the face and bite it has to serve. Common reasons include:
- A crossbite where upper teeth sit inside the lower teeth
- Crowding caused by an arch with too little width, where the alternative is extractions
- Nasal obstruction, chronic mouth breathing or a high, vaulted palate
- Airway concerns where more nasal volume and tongue space would help
- Adults told years ago that surgical expansion was their only option
MARPE is not right for everyone. Palatal bone thickness, screw position and the pattern of the suture all matter, which is why we plan every case from 3D imaging rather than an impression alone.
MARPE and MSE — the same idea
You may also see this treatment called MSE, for maxillary skeletal expander. Both describe bone-anchored expansion in a patient whose suture has fused; MSE is simply the name of one widely used design.
What to Expect, Step by Step
1. Records and planning
We take 3D imaging to measure your palate and place the miniscrews where the bone will actually hold them. You see the plan before you agree to it.
2. Appliance placement
The custom expander is fitted and four to six miniscrews are placed through it into the palate. The area is numbed; most patients describe pressure rather than pain and return to normal activity the same day.
3. Turning the screw
You or a parent turn the expansion screw at home on a schedule we give you. Over the following weeks a gap opens between the upper front teeth. That gap is the point — it is visible proof the bones separated instead of the teeth tipping.
4. Holding while bone forms
The expander stays in place, unturned, for roughly six months while new bone fills in along the suture. Removing it early is how expansion relapses.
5. Closing the space
Braces or Invisalign then close the midline gap and settle the bite. For many patients this phase is where the smile they came in for actually appears.
Why Patients Choose It
- No jaw surgery. Skeletal expansion without an operating room, general anesthesia or surgical recovery.
- Predictable movement. Anchoring in bone keeps the force where it belongs instead of tipping molars outward.
- More room to breathe. Widening the maxilla increases nasal volume and gives the tongue space to sit forward and up.
- Room without extractions. Added arch width can resolve crowding that would otherwise cost you permanent teeth.
- Works after the suture fuses. Age is a factor in planning, not an automatic disqualification.
Common Questions
Does getting the miniscrews hurt?
Placement is done with local anesthetic. Expect pressure during the appointment and some tenderness for a day or two afterward, usually managed with over-the-counter pain relief.
Will I have a gap between my front teeth?
Yes, temporarily, and it means the appliance is working. Braces or aligners close it in the next phase.
How long is the whole process?
Active turning takes a few weeks. The appliance then stays in for about six months while bone forms, and alignment follows. We give you a case-specific timeline at your consultation.
Can I speak and eat normally?
The first few days take adjustment, particularly with speech. Nearly everyone adapts within a week.
