Getting there would require probably ~5mm of upward growth and ~15mm of forward growth. This means ever year you need to move across the hypotenuse (15.81mm) and equal amount, so approx. 2.6 mm of hypotenuse movement or 0.2 mm per month. Or 0.007mm a day.

Would it be possible? Yes if you were a baby. Probably not as an adult, but there is no evidence at which speed the sutures grow when pressured in an adult.

Imagine braces in an adult. Braces move the teeth ~1-2 mm each month. "Depending on the type of adjustments made, teeth usually move between 1 and 2 millimeters each month." However this number seems to be in 10-12 year olds. Braces apply ~50 grams of force which is comparable to the amount of force fully mewing can give. (tongue maximum force is 500, lip maximum force is 300 - 100 g) so the tongue can achieve this force. However the tongue may not apply this force while sleeping, or consistently throughout the day.

The RPE generates between 2000-5000 grams of force per quarter turn with accumulated loads of more than 9000 grams. Most RPE expanders can acieve 11-13 mm of growth in ~ 3 weeks. Or 0.2 mm of lateral expansion per screw turn (you turn twice). So assuming linear translation to lesser forces. If 0.4 mm = 2000-5000 grams then 50 grams = 0.01 mm - 0.004 mm. Which means to to reach 15 mm of hypotenuse growth would require 1500 days to 3750 days. Or ~ 4 years to ~ 10 years. This assumes linear translation. In fact, it makes a lot of assumptions.

I will do some more math again this time with SME expansion. "For SME, 10 to 20 newtons of force should be applied to the maxillary region only 450 to 900 gm of force is generated, which may be insufficient to separate a progressively maturing suture. Maxillary arch-width increases ranged from 3.8 to 8.7 mm with slow expansion of as much as 1 mm per week using 900 gm of force." So that says. 1 mm per week or 0.142 mm per day using 900 grams of force. Well the tongue cannot generate 900 grams of force.. So we need to convert this down. I imagine subconscious mewing generates 50 grams of force at the absolute minimum. As 50 grams of force is roughly the amount of force it takes to hold up a golf ball. ..... converting this down. 0.142mm by 900 grams gives ~0.008 mm per day at 50 grams a day. Which means to move 15 mm of hypotenuse distance would require 1875 days or ~ 5 years of mewing. Again this is assuming linear growth which is impossible to assume because everything about the body is curved or constantly fluctuating.

Let me just write out all the assumptions I made in my math. 

• Tongue applies the same directional force as a pallate expander (it doesn't, tongue is upwards force, pallate expander is sideways)
• The maxilla moves the same as the pallate
• Complex 3D movement is the same as 2D palatine movement
• An average mewer is using 50 g of force daily
• 50 mm of force achieves a proportional growth that 900 and 2000-5000 grams achieves.
• 15 mm of hyptonesual growth is what your picture entails
• Growth is constant as the maxilla begins straightening out

BUT TLDR; Assuming all those things then 6 years seems like a not to foolish timeframe to expect realistic results in facial aesthetics.

I'm actually kind of blown away with my math. As far as I'm aware. No poster has ever done this sort of math, and I never really expected me to be the one, but this post really inspired me.

I'm actually kind of interested in being a little more specific in my math because I really did not expect to get such a reasonable number of 5 years. First thing I'm going to do is go measure my own face and see how much maxilla growth I need to be satisfied. In the meantime here is a picture of my face, as I imagine this post is going to be pretty popular here, and I would like someone to photoshop me with correct facial posture. https://imgur.com/dsNYpZd

I swear that I am literally moved by your answer. I'll try to respond better later.

Thank you

I need about 5-7mm of upwards growth of the maxilla, and between 7 and 12 mm of forwards growth. I don't really know how much palantine growth I need probably about 10-12 mm.

I also would like to know estimates on just how much pressure the tongue is exerting on the pallate during mewing. And the average. Roughly measuring with my scale, here's how. I close my eyes and focus on connecting my tongue and finger and try my hardest to push down with my finger the same as which I push UP with my tongue. Just barely touching the tip of my tongue to the roof of my mouth, I was pressing down on the scale an average of ~10 g, half way mewing (soft mewing) NO POSTERIOR THIRD I got between ~40-86 g, and then with the posterior third, fully mewing without pushing in excess I got ~100 - 180g. 

This is very very rough estimating. Sceintifically we would someone to wear a pressure sensitive device on their palate a full 24 hours then find the average force. I feel like my current average of 50g is a fairly reasonable estimate for posterior third mewing. Sometimes the person is going to be putting 180 g and sometimes they will be sleeping and putting 0 g. So I feel like 50 g is the "person who is serious at mewing" estimate as of right now. Until someone gives me solid logic otherwise. 

Another issue is the movement of the maxilla movement. When you mew, most of the force is going upwards. Which means you should see much quicker upwards movement of the maxilla than palantine expansion... In a closed system. But we are not in a closed system. The maxilla has 12 sutures and is anchored by almost every bone in the skull. 

We know the rate at which the palatine suture can expand when a directly perpendicular force is brought upon it (like that of an appliance). But the expansion rate is going to be much slower when being expanded at a non perpendicular angle (like that of a tongue). Which basically means I have no clue if my estimate is even logical. I have no clue if translating the perpendicular expansion of the palate can be directly applied to the messy, diagonal, and multifactoral correction of the entire face.

Obviously there is a difference between 50g of forms being brought against one suture, and 50g of force being spread over 12 sutures and various angles. This leads me to believe that the first thing that will be corrected from mewing as one suture is most likely going to be taking the brunt of the force from the tongue until it corrects with its symmetrical suture. This leads me to believe the first thing mewing should correct is the most critical asymmetry.

And actually the more I think about it the more I've realized the mistakes of my math. But i'm too tired tonight and will think more about this tomorrow...

Yes,

Those answers are mindblowing. In particular the fact that your math matches to my realistic/rational expectations  when It comes to estimate the time It requires.

Another point that I took in count Is that my right jaw joint clicks if I open and close my mouth keeping It relaxed, but if I jut It a very few mms ( 5 at very most) It stops. So It may be an indicator of the forward growth I require

In addition the look I got photoshopping my pic kinda SUITS ME and It make me look way more similar to my mother and sister rather than my father and my brother who SUFFER OF ALLERGIES. 

I mouthbreathed for other childhood reasons...

If you wonder about my phenotype... I am North Italian

I am absolutely not aware how braces work and how much force they apply.

" time of more important than force" cit. Mike Mew

@mewmouse500 ... If you Wish, I'll send you my two separated pics so you can take more accurate mesurements

Thank you, your very kind. But I would much prefer getting your measurements. 

It's been a day since I made that post and I realized a lot of the flaws of my math in coordination with mewing.

I don't believe hard mewing is the correct way to achieve results. I believe hard mewing recess the mandible and the eye sockets. Soft mewing is the only truth.

If this is the case then the forces generated by the tongue is completely dependent on the level of recession in the maxilla. IE the more recessed the maxilla, the less space for the tongue, so the more force the tongue will subconsciously generate. This means that it is currently impossible for me to estimate the Time To Mew. Also I did not calculate swallowing. Swallowing generates way more force then mewing ever could. We swallow around 500 times a day. I also did not factor in chewing.

I also made a huge mistake. 50g of upward force on the maxilla, is not the same as 50g of force perpendicular to all 12 sutures of the skull.

This is obviously, a huge mistake. I need to rethink just where the forces are going, figure out which sutures need growing, and estimate just how much force is applied per 24h cycle.

This is going to take me a while. I'll probably be working on this for a while. But I still think 6 years is a reasonable time frame. But I'm looking at ways to optimize mewing so the end results are a balanced face. 

My immiediete goal is figuring out which suture of the maxilla gets the most perpendicular force from mewing.

Take your time, I would be glad if you can provide even further considerations. What kind of measurements do you require? 

what is your face length @Kyte?

The direction you are applying force when mewing is very important, recently I've been trying to direct my tongue forward more as previously I was only noticing the effect in my cheek bones not my nose and mid face, greater forward force rectify that and in my case I need more forward growth to allow proper expansion
