(NOTE: For this post, I will not discuss how prenatal maxillar development affects postnatal maxillar development. Given that most babies experience relatively similar forces inside the womb, we will generalise this circumstance, and, ignoring abnormal cases, suppose a common starting postnatal point)
TL
R for lazy people:
Thumpulling alone is not powerful enough to be the substitute of the natural forces that develop the maxillary bones, but thumpulling can be a very good tool to maximise your development so long as your sutures are still malleable and you are following all the other needed habits (proper hormones, sleeping well, tongue and overall posture, mouth breathing, correct swallowing and proper chewing.)
Thumpulling alone won't ascend you, but I was thinking about this topic and the last post curse got me so I posted again after deciding not to touch this forum again.
Apart from retarded takes, the most common issues with thumpulling, are summed up in two criticisms:
1) That thumpulling doesn't cause enough strain to trigger bone remodeling
2) That thumpulling isn't a constant force with ancorage and direction, thus, if won't remodel the bone.
The thing is, I do agree with both criticisms but I don't understand how is it a problem if we put a bit of though into it:
1) The maxillar develops by both constant forces (like proper tongue posture), and by rapid, fleeting forces (like chewing)
2) A pulling motion is actually needed for the development of the maxillar since your ancestors used to chew food with their hands, thus, upon tearing the food they would press it forwardly and, since it was hard and raw it would signal the forward growth of the maxilla.
Therefore, the mistake is in seeing thumpulling as a constant force that needs anchorage, rather than seeing it as a complement to the repetitive, regular forces.
3) The strain needed to activate osteocytes and other bone-remodeling mechanisms does not need to be given in one outburst of force.
Elaborating this third point, the minimum threshold for bone remodeling is a strain of 1000-1500 µε, and it is said that mewing and swallowing can't reach that.
This is true, because if you use the " ε=σ/E " formula used to calculate strain levels on the bone, you will see that mewing (aka proper tongue posture) causes ~0.4 µε and that swallowing will cause ~1µε.
This is thousands of times less that the needed force, indeed, but the thing is, by calculating it thus we are only taking into account the force that the tongue exerts against the palate in one specific measure of time. It doesn't calculate, however, the strain caused by constant application of that force over time (ideally, 24/7). We swallow at least 900 times a day (probably much more( and we should mew 24/7.
This is directed force, especially if the posture of the body is proper, so that the angle between the maxillar and the spine is low (otherwise it will cause downgrowth), this would optimise the vector of the force.
If we then take into account that each chewing motion exerts around 150 newtons (although many people can reach up to 500 and 700 people), we could use thumbpulling as an complementary force of the same quality as chewing, so long as we push in a very clear direction for a long amount of time at full strength, and not behind the teeth to avoid mallocusions but above.
Bones react to repetitive strains over time. This doesn't mean that the straing "builds up" (for example, it would be a mistake to say that having a microstrain of 1 µε 1000 times a day is enough to reach that 1000 µε threshold, in fact doing the maths if we supposed that the strain was cummulative it would give you a total of 801.790µε a day which is pure and utter bullshit.) but that it reacts from a pattern of constant, high frequency-high magnitude.
Let's suppose you can do 30N of force for intervals of let's say, twenty seconds. You do this repeatedly until you reach 10 minutes a day, split into session in the morning, evening, afternoon and night.
This is literally an artificial stimulation of the cyclical, repetitive fores that cause the intermittent strain that bone responds to.
Four smalls notes before we finish:
- In reality, the strain force generated will be absorved through the flesh and soft tissue of the mouth to the strain that gets to the bone is going to be lower. Not significantly lower, but lower indeed.
- The 1000-1500µε strain level that we spoke off earlier were based on adult bones.
Children and teeangers whose bones still developing bones respond to lower thresholds of strain.
- "Muh unless you're three monthes old you can't change anything" Your biological age is far more important than your chronological one in these matters. If you are 18 but you were a late bloomer at 16, your biological age is like 15-16 so you still operate under lower thresholds of strain.
- "Muh your maxillary sutures are close at 15" On average, some studies define closure as the start of the bony fusion which does indeed start around 15 for the average person. Average meaning, a generalisation without taking into account sex (women mature faster than men), biological age (not the same thing to be an early bloomer than to be a late one), and other circumstances. Lots of other studies show that the full closure of the suture happens around your 20's, and that many other sutures remain open far more time.
Bye retards.
