Expansion & Arch Development
MARPE / MSE Expander
Expansion for the patient whose suture is no longer going to open on a tooth-borne screw.
3D bands available
Printed bands. Same appliance.
Send a scan instead of impressions and the bands are laser sintered to fit from the file, with the rest of the appliance built as usual. No separators, no band-fitting appointment, and the bands seat first time.

A MARPE carries the expansion screw on a body that is anchored to the palate with mini-screws, so the force goes into bone rather than tipping the molars. That is what makes skeletal expansion possible in late adolescents and adults without surgery.
We build to your screw system and placement plan. Send the cone beam so the body can be designed to the palatal vault and the intended screw sites, and tell us the number of eyelets. Bands or a bonded body, and a tongue crib if you want one, are all options.
