I'm considering the VLC implant from Implantech. I'm wondering which size would be best for me, small or medium. I'm a bit confused on the dimensions for this particular implant style. The sizing guide seems to indicate that the VLC-M provides 1cm of forward projection. And the VLC-M sizing chart shows that dimension C (the thickness) is 1cm. But since it extends out at a 45 deg angle, wouldn't the forward projection would be <1cm? I'd think it'd be 1/√2 cm because of the angle. Thanks!
