I don't think there is much difference between sell ligating braces and traditional ones. The self ligating ones take up less tooth area, so they may effect the tooth enamel less, but are thicker, so irritate the lips and cheeks more. For the record I have self ligating braces, but clear brackets only on the top 6 teeth. With a class 3, you can't see my top teeth much anyway, at least not preop. My ortho also uses Suresmile. That may make the most difference when it comes to precision and speed of moving teeth (if it works as advertised), and it's applicable to all brackets. You may also consider lingual braces. But they are typically very expensive, slower to move teeth, hard on the tongue, and surgeons tend to dislike them. My surgeon reckons they are not precise enough.
