- Why Angle Society? (Part 1.)
I am often asked many questions about my techniques and opinions about treatments, but recently I was asked to share my thoughts about the Angle Society.
I am a member of the Angle Midwest Component and it took me five grueling years of preparation before being accepted into this prestigious society. In retrospect, I feel the process of qualifying is the real magic, as one learns so much during the process and I appreciate this process just as much as I do rubbing shoulders with the world’s best Orthodontists at the Angle Society's meetings.
Ever since I became interested in Orthodontics I have been obsessed with Dr. Angle’s life, technologies and ideas, which have proven to be a great way of learning our profession. This started 30 years ago and when asked recently why there should continue to be an Angle Society I came up with a threefold answer.
Firstly, to be a beacon to all the young doctors so that they can also aspire to become members.
Secondly, to act as an anchor, to prevent us from drifting aimlessly through this ocean full of fascination, mystery and challenges.
Thirdly, to function as a port in which members can dock, mingle and return laden with information to their practices.
I sincerely hope that these three aids, beacon, anchor and port can also help facilitate your professional life as we march together on the path to glory.

Dear Dr, why plan B cause less torq loss of ant teeth than plan A. Both are extraction plans and I think the only differences here are the amount of extraction space and the correction of X-bite in tooth no 7. When retracting the front teeth, we both expect the torq loss and more retroclination of L insicors.
Pls explain it for me. Looking forward to hear from u soon. Thank u Dr.
What an excellent, detailed video! I loved it!
I don't see the need for extraction of 7s as opposed to U5s, L4s. With PM extraction, miniscrews can be used as an adjunct, if necessary, rather than being a requirement.
I guess the main problem would have been to correct the 7s' scissors bite, using cross elastics to solve it is prone to open the bite even more-especially in a high md' angle case like this one... Besides extracting the 7's free space for the impacted 8's without the burdon of a fixed amount of space you must close.. Not to mention the biggest advantage of it all... No need to bond 7's... Yeeey :)))
kfzofa this is a good question. You can get the same result and achieve it more easily (as you have more posterior Anchorage) with the typical CIII extraction pattern. but then you have a typical extraction case where four premolar are missing. If you extract 7’s and supplement the Anchorage to correct the malocclusion with labial segment in same place as premolar ext case, then you have essentially an intact arch similar to a non ext 7-7 arch and don’t have to deal with impacted 8’s. Remember 7’s give more space than premolars so it is possible to disimpact 8’s and correct the labial segments- but you need to supplement your posterior Anchorage with screws. Another way to look at it is that if you extracted premolars you are very unlikely/definitely not going to disimpact 8’s. So this case presents a really good argument for alternative treatment planning. Unfortunately this not done often in the UK where I am based, as tend people go for simple treatment and not worry about 8’s - until later. I’m interested to know how you and colleagues approach such a case.
amit goldwaser I agree extraction of 7’s will disimpact 8’s. I recommend molar extractions in case where the prognosis is poor. Often 7’s is a really good option and should be done - but be warned the 8’ esp lower ones often come through at a mesio- angular position and you must be prepared to upright them - which is always a welcome challenge and worth doing!
Also you can address scissor bite correction with premolars but the advantage of 7’s is not to deal with removal of 8’s.
