A clear patient guide
What is MARPE?
MARPE is an upper-jaw expander supported partly by small orthodontic mini-screws. In selected cases it aims for more skeletal expansion with less reliance on the teeth.
It is not suitable for everyone. Careful assessment of bone, gums, teeth, and skeletal maturity is required, and 3D imaging may be used for safe planning.
Digital planning
Imaging may guide the dimensions and anchorage positions.
Regular review
Response, hygiene, and stability are monitored throughout expansion.

Frequently asked questions
General educational answers. A direct clinical assessment remains essential for choosing the right appliance and treatment duration.
Is MARPE suitable for every adult?
No. Suitability depends on skeletal maturity, palate anatomy, bone, and gums, and other options may be considered.
Can a gap appear between the front teeth?
A temporary gap may appear in some patients during expansion and can then be managed within the orthodontic plan.
How long does expansion take?
Activation and retention periods vary with the plan and response and are not identical for every patient.
