MARPE
Adult palatal expansion
MARPE
For adults with a narrow palate, crowded teeth, or airway restriction, MARPE, Microimplant-Assisted Rapid Palatal Expansion, offers a non-surgical way to widen the upper jaw. At Rebis Health, MARPE is part of a comprehensive airway treatment plan guided by board-certified sleep physicians, orthodontic specialists, and airway-focused providers, with a focus on breathing and sleep quality, not just dental alignment.
MARPE is a non-surgical palatal expansion technique for adults that uses small, temporary skeletal anchors placed in the upper jaw to support a customized expansion device. Over time, the device gently widens the maxilla, which may help improve:
- Nasal airway space
- Breathing efficiency
- Jaw alignment
- Facial structure and balance
The basics
What Is MARPE?
A newer option
Why MARPE Is Changing Adult Orthodontics
Historically, adult palate expansion required surgical intervention. Advances in imaging and orthodontic technology now allow many adults to achieve skeletal expansion without surgery, offering a minimally invasive alternative for patients seeking to improve both airway health and dental alignment.
MARPE is increasingly used as part of treatment for sleep-disordered breathing and mild to moderate obstructive sleep apnea. A multi-center controlled trial found measurable improvements in daytime sleepiness and OSA-related quality of life in adult patients with a narrow upper jaw following MARPE treatment, though outcomes vary by individual anatomy and case complexity.
What patients may notice
Potential Benefits of MARPE
MARPE is often recommended for patients with airway-related concerns, narrow dental arches, or breathing dysfunction. Patients may experience improvements in:
- Nasal breathing and airflow
- Airway volume
- Snoring and sleep quality
- Dental crowding and bite alignment
- Facial symmetry and development
When incorporated into a broader airway treatment plan, MARPE may help address underlying contributors to poor sleep, mouth breathing, and airway restriction.
Before treatment
Comprehensive Airway Evaluation and Treatment Planning
Successful outcomes with MARPE depend on precise diagnostics and individualized planning. At Rebis Health, each patient undergoes a comprehensive evaluation that may include:
- CBCT imaging to assess airway structure and craniofacial anatomy
- Sleep study analysis reviewed by sleep medicine physicians
- Digital dental impressions
- Nasal breathing and airflow assessment
- Tongue posture and mobility evaluation
This approach allows our team to determine whether palatal expansion is appropriate and how it may support each patient's breathing, sleep, and long-term health.
Coordinated care
A Multidisciplinary Approach to Airway and Sleep Health
MARPE is part of a broader shift toward airway-focused and integrative orthodontics, where treatment supports respiratory function, sleep physiology, and overall wellbeing. At Rebis Health, care is delivered through a collaborative model that includes:
- Sleep medicine physicians, providing board-certified oversight
- Airway-trained orthodontic providers
- Dental and craniofacial specialists
- Integrative health practitioners
This coordinated approach allows us to address the structural and functional factors that influence breathing and sleep. For many adults, improving sleep begins with improving how they breathe, MARPE offers a pathway to support both.
Common questions
Frequently Asked Questions
-
MARPE (Miniscrew-Assisted Rapid Palatal Expansion) is a non-surgical orthodontic treatment used to widen the upper jaw in adolescents and adults. By using small temporary anchors, MARPE allows for skeletal expansion of the palate, which may improve breathing, airway space, and dental alignment.
-
Yes, many adults are candidates for non-surgical palatal expansion using MARPE. Advances in orthodontic technology now allow for expansion of the upper jaw without the need for invasive jaw surgery in select patients.
-
The upper jaw forms the floor of the nasal cavity. When the palate is expanded, it can increase nasal airway space and reduce resistance to airflow. This may support more efficient breathing during both wakefulness and sleep.
-
MARPE may be used as part of a comprehensive approach to treating sleep-disordered breathing, including mild to moderate obstructive sleep apnea. It is typically combined with medical evaluation and airway-focused care to address underlying structural contributors.
-
Patients undergoing MARPE may experience improvements in nasal breathing, airway volume, sleep quality, and snoring. Additional benefits may include improved dental alignment, reduced crowding, and enhanced facial balance.
-
Most patients experience mild pressure or discomfort during the initial phase of expansion. This is generally temporary and tends to improve as the body adapts. MARPE is considered minimally invasive compared to surgical alternatives.
-
Candidacy depends on factors such as skeletal development, airway structure, and overall health. A comprehensive evaluation, including imaging and airway assessment, is necessary to determine whether MARPE is appropriate.
-
The active expansion phase typically occurs over several weeks, followed by a stabilization period to allow the bone to adapt. Total treatment time can vary depending on the individual treatment plan and whether additional orthodontic care is needed.
-
Rebis Health offers MARPE as part of a medically guided airway and sleep health program in Colorado. Care is delivered through a collaborative team including sleep physicians, orthodontic specialists, and airway-focused providers.
