Just seen that I completely ignored your question, the SARPE device, the RPE, come in different variants with different arm types of how many teeth they anchor on to. Usually they anchor onto the 2nd molar on each side and one of the premolars like this,@Silver Just to be sure, when you mention posterior expansion with SARPE, you mean more expansion to the very last molars than the intermediate ones? I've always thought that SARPE expanded the entire smile, like this:
Lots of of posterior expansion would be needed for a smile like Rodrigo Guirao's from what I can understand, it seems very wide in every direction, posterior and anteriorly, very full and not "flat" like mine or most people's smile:
My goal is to have that kind of full and wide, not just wide but flat smile. Again thanks for the help bro.
Since it's anchored in the middle/posterior part of the maxilla, you will still see expansion here but since the SARPE design is flawed which Dr. Kasey Li has proven several times you will fail to see the PNS expansion that you are looking for to get that desired 12 teeth smile, imo. Obviously I could be wrong but from what I know this would be the outcome.
