Is non-surgical palate expansion in adults possible?

Yes, adult arch development is definitely possible. We have been doing it in my office for 25 years. It works, if done correctly. There are multiple appliance options for non-surgical adult arch development, including: DNA, ALF, SLDA, Schwarz, Meridian, etc. Some of these appliances are fixed (cemented into the mouth) others are removable.

If your teeth are excessively crowded you basically have two options for treatment: 1. extract teeth or 2. enlarge the space. Extracting teeth is RARELY the best option as it leads to: a constricted airway, compromised TMJ's, adverse facial changes, and unstable results. Making the arches bigger will result in: enlarged airway, healthier TMJ's, facial enhancement, wider more attractive smile, and 2-8 more teeth!

Good luck!

HiAll the palatal expasions (surgical and no surgical) make a gap. MARPE it's a new approach to resolve palatal compression, You can read the article attached and have an idea of what is .On the other hand, we have DENTAL expansion, we only modify the dental arch and most of the cases there's no gap.
