Retrognathia and an underbite

[x]

This seems to be what I have, yet you don't see cases of it too often. Anyone know what sort of abnormal growth can cause this?

With retrognathia I mean the lower jaw not the upper

kinda like this?

NEREA (PAMPLONA): CLASE III

man this is tough. i dont think you'll find a comprehensive explanation as to why your jaw and face grew the way it did from a specialist. it is helpful to look at pictures when you were younger and see the changes during the duration of key growth periods. but the ship has sailed as far as a complete reversible goes so it might not be worth thinking about.

my guess is something prevented your upper jaw from growing horizontally, if the tongue fails to form the palate then you have a problem.  it can lead to many many problems. poor oral posture, hyperactive swallowing, mouth breathing, etc..etc. all issues that disrupt growth.

So basically when the palate doesn't form the tongue doesn't have a proper resting space and disrupts growth with it's unnatural positioning?

I had my tonsils removed when I was 10 that could've porentially been the cause. I'll look at my family photos over the weekend, I know my teeth were f**ked up as far back as when I was 8 at least.

if the tongue successfully forms the palate (and this occurs early in childhood, before 6) then a tongue thrust later on won't be too harmful. not sure about the tonsils, if anything that would help open the airway.

the teeth don't matter that much by themselves. but if the upper jaw is denied the opportunity to grow forward early in childhood the risk of developing long face syndrome increases exponentially.

it really depends on a case by case basis, since abnormal growth varies depending on the individual. plenty of research has been done on upper jaw growth and its relationship with the mid and upper face. there just isn't much incentive to incorporate the analysis into treatment plans because once the bones hardened it can't be reversed.

only a few identified genetic diseases cause the upper jaw to grow vertically, such as adenoid facies.

consider extractions. no one thought extractions would influence facial growth, but you know it does now.

any doctor will tell you the environment can influence body growth. if you dont sit up sit up straight will you not develop poor posture later in life? most features are programmed genetically but it isn't set in stone.  headgear for example can interact with growth. does anyone seriously think genetics is going to trump the force of the appliance on the jaw?

you have to look at cause and affect relations. the evidence is too overwhelmingly in this case.

Yeah that's what I mean. And likewise a woman drinking or eating in poor nutrition during pregnancy can have a profound effect on the fetus and set it up for future jaw issues.

But I think analysis can be important, like I said if part of the issue was my ramus not growing to it's proper length, wouldn't it be of greater benefit to extend the length of it, thereby flattening the occlusal plane properly? It seems like standard jaw surgery would only compensate in some ways but still not fix the overarching issue. That's just an example I can think of off the top of my head.

jaw surgery is just that - compensation. at least in your case it would be since the abnormal growth extended beyond the jaw

not sure what you mean by extending the length of your ramus. growth cannot be reproduced.
