AFD Expansion Protocol (MARPE)
Non-surgical palatal expansion to improve breathing, sleep, and facial development in teens and adults.
At the Center for Airway & Facial Development, we use miniscrew-assisted rapid palatal expansion (MARPE) as part of an airway-centered program to widen a narrow upper jaw, create space for crowded teeth, and reduce resistance to nasal breathing.
What Is MARPE & the AFD Expansion Protocol?
MARPE (Miniscrew-Assisted Rapid Palatal Expansion) is a way to safely widen the upper jaw using small anchors placed in bone instead of relying only on the teeth. This allows expansion in older teens and adults where traditional expanders or “childhood-only” options no longer work.
At AFD, we’ve built a complete protocol around MARPE that blends:
- 3D CBCT imaging to evaluate airway, nasal passages, and jaw structure.
- Digital scanning & CAD/CAM guides for precise appliance planning.
- Airway & sleep-focused diagnosis instead of just “crooked teeth.”
- Interdisciplinary support with ENT, sleep medicine, myofunctional therapy, and more.
The goal is not only a wider smile, but a more open airway and better foundation for breathing and sleep.
Key Benefits at a Glance
- Non-surgical alternative where many patients are told only surgery is possible.
- Potential improvements in nasal airflow and sleep quality in properly selected cases.
- Can reduce snoring, mouth breathing, and airway resistance.
- Creates room for crowded teeth, helping avoid extractions in some cases.
- Guided by imaging, software, and experienced clinicians for safety and predictability.
Who Is MARPE / the AFD Expansion Protocol For?
We segment candidates by age and symptoms, because most people do not search for “MARPE” — they search for help with breathing, snoring, or crowded teeth. If any of these sound familiar, you may be a candidate.
Teen Airway & Growth
- Crowded teeth, narrow smile, or crossbite.
- Mouth breathing, snoring, or restless sleep.
- Recommended extractions due to crowding.
- Desire to avoid more invasive treatments later.
Adult Orthodontic & Airway
- Crooked or crowded teeth never fully treated in childhood.
- Breathing issues, chronic congestion, or snoring.
- Searching for non-surgical options after being told “you’re too old to expand.”
- Often juggling budgets but very motivated to feel and sleep better.
Sleep & Snoring Worriers
- Loud snoring, mouth breathing, or mild obstructive sleep apnea.
- Fatigue despite “enough hours” of sleep.
- History of sinus or nasal obstruction, allergy, or ENT problems.
- Searching for root-cause structural solutions, not just more devices.
“There Has to Be Another Way”
- Already told they may need SARPE or orthognathic jaw surgery.
- Interested in functional / holistic approaches that work with the body.
- Highly engaged, research-oriented, investing in long-term health.
- Open to combined care with ENT, sleep, and myofunctional therapy.
Not everyone will qualify. Candidacy always depends on detailed imaging and clinical assessment of the midpalatal suture, maxillary width, and overall airway anatomy.
Why Choose MARPE at the Center for Airway & Facial Development?
1. Airway & Breathing, Not Just Straight Teeth
Our practice is built around the idea that how you breathe and sleep is just as important as how your smile looks. Expansion is used when it supports both dental alignment and airway health — not as a cosmetic add-on.
2. Non-Surgical Skeletal Expansion
MARPE uses small bone anchors to apply expansion forces directly to the skeleton. In many adults, this can create true skeletal change where tooth-borne expanders alone are not effective, and may help avoid more invasive surgery in the right cases.
3. High-Tech, Personalized Planning
We rely on CBCT, digital scans, and customized CAD/CAM insertion guides to plan exactly how the appliance is placed and activated for your anatomy.
4. Safety, Monitoring & Expertise
MARPE is powerful and must be handled carefully. We evaluate:
- Suture maturation and maxillary constriction.
- Nasal cavity and airway volume.
- Periodontal and root health.
Our team has extensive training in airway-focused orthodontics and adult expansion techniques and is attentive to potential complications and contraindications.
5. Whole-Body, Team-Based Care
Because airway issues rarely live in isolation, we collaborate with:
- ENTs and otolaryngologists
- Sleep medicine physicians
- Allergists and pulmonologists
- Myofunctional therapists and other functional providers
Your MARPE / AFD Expansion Journey
While every plan is customized, most journeys follow a similar pattern:
- Airway & Expansion Screening We review your symptoms, sleep history, and medical background, then perform or review CBCT imaging and dental records to assess your jaw, palate, and airway.
- Custom Digital Treatment Plan Using 3D data, we design a MARPE appliance and, when indicated, create insertion guides to place miniscrews in the optimal positions.
- Appliance Placement & Activation The appliance is placed and activated gradually according to your individualized protocol. Most patients feel temporary pressure and mild discomfort that typically improves as they adjust.
- Airway & Functional Support Many patients benefit from myofunctional therapy, breathing retraining, or co-management with ENT/sleep providers to maximize results and help new space function well.
- Stabilization, Retention & Follow-up We hold the new skeletal width while bone fills in, then transition to retention and, when needed, aligners or braces to refine tooth position.
MARPE Self-Assessment: Could a Narrow Jaw Be Limiting Your Airway?
This checklist is not a diagnosis, but it can help you decide if an airway-focused evaluation makes sense. Check all that apply:
If you checked 3 or more boxes, it may be worth exploring whether your upper jaw and airway structure are part of the problem.
The next step is a comprehensive Airway & Expansion Screening, including 3D imaging and a personalized review of your anatomy and goals.
For Referring Dentists, Pediatricians, ENTs & Sleep Physicians
When to Consider MARPE / Skeletal Expansion
Consider referring to AFD when you see:
- Transverse maxillary deficiency or clear maxillary constriction.
- Crossbite, dental crowding, or limited arch width.
- Chronic mouth breathing, nasal obstruction, or long-standing congestion.
- Snoring, suspected sleep-disordered breathing, or mild OSA linked to a narrow palate.
- Patients told that traditional expansion is not possible because of age.
Our Co-Management Model
We welcome collaboration. Our team shares imaging, progress notes, and outcomes with referring providers and invites co-treatment planning for complex cases.
MARPE Referral Snapshot
Ideal referring partners:
- General & pediatric dentists
- Orthodontists seeking airway-focused collaboration
- ENTs / otolaryngologists
- Sleep physicians & pulmonologists
- PCPs, concierge medicine & functional medicine providers
To refer a patient, please send relevant records and imaging and indicate “MARPE / skeletal expansion evaluation” on the referral.
Frequently Asked Questions About MARPE & Adult Expansion
Why the Center for Airway & Facial Development?
We are a specialized, interdisciplinary center dedicated to early intervention, airway-focused orthodontics, and whole-body collaboration. Our mission is to address the root cause of problems like crowded teeth, poor sleep, and breathing difficulties — and to support healthy facial development at every age.
Our providers work as a team, combining expertise in early intervention orthodontics, TMJ and sleep, tongue-tie and frenuloplasty, myofunctional therapy, osteopathic medicine, and more. MARPE and the AFD Expansion Protocol fit within this larger vision of breathe, sleep, grow, develop & thrive.
Ready to Explore Non-Surgical Jaw Expansion?
If you or your child struggles with snoring, mouth breathing, or crowded teeth — and you have been told “there is nothing else to do” or “you’re too old to expand” — a focused airway and expansion evaluation may open new options.
Start with an Airway & Expansion Screening to see if the AFD Expansion Protocol (MARPE) is right for you.
