If your chin looks recessed, possibly the maxilla is *rotated* in the wrong direction. I found a thread about this on a another forum just yesterday! It is the same what I was talking about recently on this forum, so i'm glad he looks at it the same way, which increases the chance of this being right information. (after all, this forum is like people exprimenting on themself and sharing knowledge) ...
If anything, you should focus on pushing the forward part of the maxilla upwards...because the more your frontal palate is down, the more your mandible is rotated in such a way that your chin seems ("is") recessed. This means that you might have enough bone in your chin that your chin bone itself is good enough, but its rotated wrongly, making it , concretely speaking, look recessed
read this one...and ignore the last few posts. That forum has interesting points sometimes, but 90% of it is purely negative or actual nonsense
http://sluthate.com/viewtopic.php?f=2&t=1006203at the moment I use belt facepulling and before this I used normal facepulling from plato's site (if you know it?) with the hockey helmet. When i started facepulling wit hteh helmet i attached elastics and made the direction of pushing upwards and forward (as it should!). However, since I had 4 attachement points on my custom made retainer, I attached 4 elastics to all of them. However, what I did not realise enough is that the elastics attached to the backside of the retainer (meaning deepest in my mouth) were stretched the most, since the distance from the pulling helmet was longer but the elastics just hte same length. so basciaclly I was pulling the back side of my palate (deep in mouth) *more* than the forward part of maxilla. This way of facepulling improved alot of things in my face, especially my eye area. While My eyes were roundish before, they are very horizontally shaped now (whichis good). However, by pulling that part of my maxilla up and not as much the front (because the elastics of the back had much more pressure of them) I made my maxilla come forward and upward, but rotated it accidentally a bit the wrong way too. Meaning, my overjet/overbite is slightly worse than it was before facepulling. At first I did not notice, because my face just looks alot better, and wider and such. When I found out I was kinda shocked, because i didnt understand why that seemed worse, but my face seems better. My jaw looks better too. However, then I found out that I was just focussing too much on the back of my maxilla but not the front..so recently i've deciced i should focus most on getting the front of my palate upwards, so my mandible will rotate, and my chin will look more prominent and less recessed....
I currenly use a belt that I bite on with the molars closest to my lips, and then basically pull the belt upwards as much as possible. After that I put my thumb right behind my 2 most frontal teeth, and push and push as hard as I can for a few seconds. I hear alot of cracking, whcih is in cranial restructuring often a good sign. At least something is changing!
The thing I have not focussed on the most is keeping tounge posture right. It's the thing I know i will have most difficulty with too. My nose is often a bit clocked, making it seem like ican not get enough air this way..Also, I am a pretty absend minded person, so thinking about something in th background,like keeping my tongue in the right position, will for sure be hard for me . I hardly remember were I put things i nmy house! Often looking for where I leave stuff..!
Hope this helps you a bit..If you need help, just say so!
So yeah that's just my 2 cents !
