I thought I'd expand on my thoughts regarding locking brackets. I suspect that some surgeons do not like these because, perhaps, they're a pain to deal with should a wire pop out during surgery. Maybe they have the tools to open these locks on hand, but they'd have to have tools from all the different manufacturers.
Post-surgical wire changes are another reason I don't feel confident with these. I had a type that required much downward pressure in order to "lock" the wire in place. This really jolted the tooth and my entire jaw with every bracket engagement. The thicker the wire, the greater the jolt. Intuitively, this is dangerous for barely healed bone, but it's just my take. I cannot comment on other brands and whether or not application of wires create the same pressure shock to the jaw. Ask your surgeon.
