How do I get Bimax or BSSO covered by public health?

[s43q]

I am 14 years old and live in Spain so I cant get cosmetic surgery, but I have a terrible overbite, its so bad I genuinely look like a little kid if I don't perma-jut, but it still looks slightly wrong and could develop TMJ, I don't think I have sleep apnea, what I want to know is what could I lie about to get a free bimax.

Lying won't do shit... You should physically fool the sleep study...
