PAOO™ vs. Traditional Orthodontics

For patients, the greatest benefit to PAOO™ is the shortened treatment time from years to months. There are also many additional benefits to PAOO™ over traditional orthodontics:
PAOO™vs.
 		Traditional Orthodontics
  • Treatment duration: less than 1 year 
  • Treatment duration: 18-36 months
  • Lesser need for tooth extractions
  • Greater need for tooth extractions
  • Chances for relapse are low
  • Chances for relapse are high
  • Lesser need for additional appliances
  • May need additional appliances
  • Additional marginal orthognathic surgery may be avoided
  • Additional surgery may be required
  • Less appearance of "white spots" (decalcification) on teeth
  • Appearance of white spots on the teeth
  •  Likelihood for root resorption low
  • Root resorption chances possible

    Sorry Colin but a lot of the assertions above are nonsense. eg. appearance of white spots on teeth is an oral hygiene issue and has nothing to do with traditional ortho vs PAOO. Why should relapse be any less with PAOO? You are not cutting the periodontal ligament!! Also, why should there be a GREATER need for extractions with traditional ortho? I see value min PAOO in selected cases but these assertions are pure conjecture

    Hi David,
    Thanks for your comments. The following are responses:
    White spot lesions: Studies from U Michigan show, the longer in appliances the greater the number of white spots. Of course, I agree that white spots and decay are OH issues, but the sooner one is out of an appliance the less the risk of white spots. Also, I have not seen any gingival hyperplasia in my PAOO cases - another factor linked to limited OH efficiency, and thus precarious lesions.
    Relapse: PAOO most definitely severs the supra-gingival fibers (Fiberotomy of Edwards) minimizes relapse (Data from Ferguson (at BU)
    Less extractions in the marginal case: due to greater expansion of arch - twice Profit's 3mm for arch expansion from 3mm to 6mm without the risk of recession (I have many cases to demonstrate this effect, with long-term follow up)
    David, to me the primary value of this procedure is substantial suppolemental grafting of ultra-thin facial alveolar bony cortices. The speed and other factors are secondary. This grafting will minimize the risk of gingival recession, so frequently see following decrowding of the crowded arch (see Renkema et. al last year).
    The evidence is here, not is the time to start thinking differently, although I have been doing so for 11 years. Tonight I had a meeting with my primary orthodontist. I am starting to review my cases for publication - we collectively agree, that without exception, our cases have done amazingly well - stable, no recession, happy patients and beautiful muco-gingival complexes. I hope you will let me share some with you if you are attending symposium in January.
    Very best wishes to you and your family and your club members
    Colin
