There are various different "styles" and techniques used in orthodontic
tooth movement. When I was in school the best known were the "edgewise"
technique and "Begg orthodontics" (some of the big names got their names
hung on their particular flavor of ortho).
I wouldn't swear to this, but I think it was Begg that had 3 stages; in
the second stage the incisors were tipped in; that was supposed to be
followed by a contrary movement accomplished by torquing the roots in.
This last stage may be more difficult to accomplish, or maybe the
orthodontist is rushed. In any case, failure to complete the third stage
of this particular style of orthodontic treatment left the incisors in
what was referred to as "rabbited inward" position. Again, this is the
detritus of my mediocre memory from over 30 years ago; I don't know if
something akin to Begg is still used. But it's definitely true that some
orthodontic patients (for whatever reason) have been left with their
incisor teeth with this inward-tipped position.

Yeah, that was kind of how Begg orthodontics worked - we were fortunate to
have a couple faculty that used it. There are some aspects of that
technique that can be used with any fixed appliance system. It's been
forever since I've seen that appliance though. I don't think hardly anyone
uses it anymore. It was all round wires with auxilliaries for tipping and
torquing.

Upper incisors can be left with inadequate torque and appear to be tipped
inwards towards the inside of the mouth. Judicious use of extractions and
proper use of the edgewise hybrids that are out there now should prevent
results such as this. Occasionally I will see a high, vaulted palate that
simply won't allow bodily retraction of the upper incisors because of the
lingual and palatal cortical plate. Not a good time to consider extractions
to reduce overjet unless you are willing to accept a result such as this.

Thanks Dan!

Thanks for all the info. I think I got most of it, except the last
paragraph by Carabelli.
Can you put it more in laymen's words: what's lingual, palatal
cortical plate?

Carabelli said that Begg's method is hardly used any more. What's the
most common method nowadays and how does it work? What's the biggest
advantage of the new method?
