People shouldn't have said you're not a candidate for jaw surgery based on those pictures. Being told you're not eligible for jaw surgery when you're convinced that it would benefit you can be devastating. I was "gaslighted" that way by several incompetent surgeons until I saw Dr Gunson. You're definitely a candidate for double jaw surgery, but less experienced observers might not see it due to the compensations you have going on, like bad head posture and normal overjet. Your upper incisors are not only retroclined but they're very far from your upper lip, which shows your maxilla's quite recessed as well. At least that's what Dr Gunson called attention to in my case and I'm having my maxilla rotated and advanced 9 mm. Since you have the money I would recommend you look into this now rather than later. I'm only 22 but I still wish I'd fixed this problem around your age -- my confidence would have been better.
Wow, 9mm, that's intense.
Could I see your side profile pics and x-rays by any chance? nvm, checked your post history and saw your pics.
I might go consult with Arnett/Gunson in the spring.
Best of luck with your surgery, hope all goes well.
