MARPE (Miniscrew-Assisted Rapid Palatal Expansion)
MARPE is an advanced orthodontic technique used to expand the upper jaw and create space without immediately relying on tooth extractions. At Beaverton Orthodontics, Dr. Tarim Song takes a personalized, evidence-based approach to determine when expansion, extractions, or a combination of both will provide the best long-term results.
This approach focuses on achieving proper alignment, healthy bite function, and long-term stability based on each patient’s unique needs.
What Is MARPE?
MARPE (Miniscrew-Assisted Rapid Palatal Expansion) is a form of non-surgical palatal expansion designed to widen the upper jaw using a specialized appliance supported by small temporary anchors.
Unlike traditional expanders that primarily move teeth, MARPE applies controlled force to the bone, allowing for true skeletal expansion. This makes it an effective option for teens and adults who may no longer be growing.
When Is MARPE Recommended?
MARPE may be considered for patients who need additional space or improved jaw alignment, including:
- Narrow upper jaw
- Moderate to severe crowding
- Crossbite or bite imbalance
- Adults or teens who need expansion beyond traditional methods
Each case is carefully evaluated to determine if MARPE is the most appropriate solution.
Why Not Always Avoid Extractions?
There is a common belief that orthodontic treatment should always avoid extractions. While expansion techniques like MARPE can be highly effective, they are not the right solution for every case.
In some situations, extractions may be the best option to achieve:
- Proper bite alignment
- Long-term stability
- Balanced positioning of the teeth within the jaw
Treatment decisions should always be based on clinical needs, not a one-size-fits-all philosophy.
A Personalized Approach to Treatment
You may hear different orthodontic approaches presented as universal solutions, but every smile is different.
At Beaverton Orthodontics, Dr. Song bases every recommendation on:
- Detailed clinical evaluation
- Jaw structure and available space
- Bite function and alignment
- Long-term stability and health
The goal is to choose the approach that delivers the most predictable, healthy outcome.
What to Expect with MARPE Treatment
MARPE treatment involves placing a customized expander and gradually activating it to widen the upper jaw over time.
Patients can expect:
- A personalized treatment plan
- Gradual, controlled expansion
- Regular monitoring to track progress
