I see alot of people talking about MARPE,
But imo i think it would more harm than good in the vast majority of people
But first of all what is MARPE?
MARPE (short for Miniscrew-Assisted Rapid Palatal Expansion.) is a orthodonic technique used to widen the upper jaw (maxilla) by applying expansion forces through bone-anchored screws to separate the midpalatal suture.
I could see MARPE as a good option if you have a very narrow maxilla resulting in posterior crossbite, dental crowding, and airway compromise.
But i belive it isn’t beneficial aesthetically in most people and here is why
1.
MARPE isn't really beneficial aesthetically for most people, because it only expands the upper jaw, not the lower jaw. The lower jaw can't be widened with expansion since it has no suture (widening it would require implants). Expanding only the upper jaw increases bizygomatic width while bigonial width stays the same, lowering the bigonial-to-bizygomatic ratio. For most people, this makes the jaw look too narrow, especially if it already is.
The only time this could look good is if your bigonial-to-bizygomatic ratio is already too high (= >1.0).
It can also disrupt facial harmony by widening the nasal bridge and altering the ESR (eye separation ratio).
Also, if FWHR is already high (ideal for males = 1.85-2.0), expanding to the point where FWHR exceeds 2.0 can make the face look too wide, hurting overall aesthetics rather than improving them.
The only time I could see MARPE being aesthetically useful is in a case with a very narrow maxilla, low FWHR, and very wide bigonial width.
If anyone can refute or challenge these points, feel free to do so, open to discussion.
