Hi BF ... this is a topic that would be better posted in the Traditional Braces forum, so that more people would see it. This section of the forum is for new members to introduce themselves.
I'm not sure that the doubling of powerchains is very common, but some ortho's may use this to help close gaps. There are other ways to do this, like making closing loops in the archwire. Talk to your ortho about the progress of your gaps and what your options are.
Good luck!![]()
