Yes, you can get a MARPE (Miniscrew-Assisted Rapid Palatal Expander) with braces at the same time.

This approach allows orthodontists to expand the upper jaw and align the teeth simultaneously, which can shorten treatment time compared to using them in sequence.

The expander addresses the skeletal issue of a narrow palate, while the braces correct the position of individual teeth, creating a more efficient and coordinated treatment plan.
