Its funny because bruxism decreases with ageThis bone grows and becomes visible under the soft tissue. They are commonly seen in patients who clench or grind their teeth. Exostosis of the maxilla and/or mandible may be the result of bruxism.

An exostosis, also known as bone spur, is the formation of new bone on the surface of a bone
yeah sure
yes but imagine the extremely little amount of force their using to hit a fucking tennis ball, it doesn't take much
I am talking about children
you still cant go back in time
"little amount of force"
exactly lol, proves her muscles had a great effect on her bone and the importance of jaw muscles and how it can influence bone
yes nigga lol, okay i was capping with "little amount of force" but chew for 15 minutes with mastic gum, your jaw will fucking ache
I am still saying, that you can help children to achieve great results.
It’s starting to become inheritable, a weak jaw, but it’s the environment and diet that still plays a factor in having good teeth and a good jaw without any need for orthodontics
op meant decrease, fuck 120 degrees is so sexy
her gonial angle wasnt even low
Fuck i cant edit my post anymore
im pretty sure you had a point where u said that with chewing you can achieve fucking primitive tribe like facial structure
pretty much
Environmental changes to body are like 100,000 years or possibly more
Yeah, if you start with a young age...
oh my god

A significant association was found between mandibular shape and muscle CSAs(masseter muscles), i.e. larger CSAs are associated with a wider more trapezoidal ramus, more massive coronoid, more rectangular body and a more curved basal arch
you are utterly retarded
how is that related to adult chewing changing bone?
i didn't say it was just letting you know lol in case you were curious, some ppl thought the study was a simulation when it was first posted here but it was actual head ct scans
do you know that it can be because of genetics/testosterone levels(which is genetic too) right?lol
like the wollfs law says maybe you can get a change where the muscle attaches to the bone aka gonial angle
Of course but it doesn’t mean it looks good
you're gonna tell me he's 20 in the left
its not the ones I was thinking of but it says the same thing.
of course, those people over did it jfl
I dont understand how no one sees how bloated his face looks
yes either way some curry had a good ascension from chewing
you cant expect us to show studies where they feed children exclusively soft or hard diets like rats and shit
so? are u seriously gonna argue he lost weight?
yes of course there are studies showing testosterone can increase ramus length, im not denying that but your greatly downplaying the importance of chewing/mechanical loading
"in rat studies"its not the ones I was thinking of but it says the same thing.
“In the present study we found that a period of 7 months with low masticatory demands in the hypofunctional group during adolescence and early adulthood had a significant effect on the lateral shape of the rat mandible”
“In vivo micro-computed tomography (micro-CT) analysis showed that mechanical load onto the jawbone by the HD affected its shape, in the way that predicted by the computer simulation. The simulation also indicated that these morphological changes redistributed the mechanical stress generated in the bone by the HD, indicating that jawbone is able to adapt its shape to changes in mechanical force.”
Global human mandibular variation reflects differences in agricultural and hunter-gatherer subsistence strategies
Variation in the masticatory behavior of hunter-gatherer and agricultural populations is hypothesized to be one of the major forces affecting the form of the human mandible. However, this has yet to be analyzed at a global level. Here, the relationship between global mandibular shape variation...www.pnas.org
“Here, the relationship between global mandibular shape variation and subsistence economy is tested, while controlling for the potentially confounding effects of shared population history, geography, and climate. The results demonstrate that the mandible, in contrast to the cranium, significantly reflects subsistence strategy rather than neutral genetic patterns, with hunter-gatherers having consistently longer and narrower mandibles than agriculturalists. These results support notions that a decrease in masticatory stress among agriculturalists causes the mandible to grow and develop differently.”
this goes exactly against what you were saying about the changes between hunter gatherer jaws and agriculturalist jaws being genetic
She looks waaaaaaaaaay better on the first pic.
Nah he just chewed and his jaw muscles are bigger
The results demonstrate that the mandible, in contrast to the cranium, significantly reflects subsistence strategy rather than neutral genetic patterns
LOL
They over did it but the guy still looks better on the right than on the left.
Like I say there aren’t any studies where they give children control diets and shit you can’t expect there to be.
then ur first research is irrelevant i already said that you can expect little changes in children
like i said, the bottom guy over did it
Man but he over did it. And that pic is frauded, with a little bit less and he would look good.
Those changes likely came from diet, as previous studies have suggested. Hunter-gatherers needed big, strong jaws to chew the uncooked vegetables and meat that often made up their menu. Early farmers, on the other hand, had a softer diet, consuming cooked foods like beans and cereals that didn’t demand such a high level of mouth strength. Over time, as jaws became smaller in response to these dietary changes, teeth didn’t follow suit, remaining around the same size. This likely directly led to the problem of adequate mouth real estate so common today. We've got modern jaws but a potentially outdated number of teeth.
he
"Our analysis shows that the lower jaws of the world's earliest farmers in the Levant, are not simply smaller versions of those of the predecessor hunter-gatherers, but that the lower jaw underwent a complex series of shape changes commensurate with the transition to agriculture."
i can send u 10-20 studies which concludes that jaws become weaker due to human evolution btw
