I've had a Haas expander in for almost a month now. I initially had a Hyrax but had nothing but problems with it. (I went through two of them because they both broke before my ortho decided to try something new and go with the Haas).
Since I don't do anything with the Haas (no turning a key), my question is, how does this expander work? I used to notice changes when I had the Hyrax in but I haven't seen any movement whatsoever since getting the Haas expander in. I'm wondering if this is a much slower working expander. Does the ortho do something with it to make it expand?
Forgive me if this has been asked before. I did a search but couldn't find anything.
Any help or personal stories would be very appreciated.
I found a description from the maker of what it is and how it works:
"A fixed maxillary expander that uses acrylic pads and heavy lingual wires to apply pressure to both the teeth and the palatal tissue during expansion."
You can google in "Haas expander" and find more information on it.
