If anybody else is interest, I should also say that the problem is that there is a stretching phase if you need more than 1,5 cm. You have to be like 2 months (I think), with a goofy looking thing in your head, stretching the skin of your skull daily. Once it's strecthed, they insert the implant. If you need the stretch, the price was 8.000, and it would take around 3 months, since the first intervention to the final one, plus 2 extra months for total recovery. I didn't want to do that knowing that if I get a direct hit, the implant may break. I like boxing and football, so I was not a good option for me.
