If that got your attention, you may find this article posted on the Align Tech site interesting:
Dr. Doug Brandt discusses "Guidelines for Retention in the 21st Century". You can download the .PDF or just listen to it from the links posted here:

His most important/enlightening points:
~ Relapse in orthodontics is universal
~ Your most stable tooth position is pretreatment
~ Genetics affect tooth position; lower lip & tongue both exert enough pressure to move teeth
~ excellent oral hygiene maintains supporting tissues so is most important during retention
~ Vivera can provide a re-alignment of up to .25 mm with full time wear in future relapse, so it's a "safety net"
~ the way Vivera is manufactured with a new set every 3 months, it's stronger than other clear appliances
With a scientific study of materials, a wear time schedule for Vivera Rx is:
1) 1st Retainer: day & night for 3 months
(going directly to overnight just won't work - & that makes TOTAL sense)
2) 2nd Retainer: day & night again for 3 months!
3) 3rd Retainer: nights only for 9 months
4) 4th Retainer: no less than 3 nights/week for 1 yr. 9 months
FINALLY - a definitive plan for retention...Gah! A bit too late in my own case, but my question posted over a year ago here is answered at last:
"With even the minimal shifting that will occur after wearing the Invisalign (or Essix) Retainers for a few months, once a new set is inserted your teeth are forced to "self correct" each time & go back to the way they were with your very last aligner in your treatment. How will this allow your roots to heal sufficiently & permanently if they are constantly getting shifted about - even if it is minimal shifting???"
Take heed all of you who are still in your treatment phase:
It is absolutely vital that your clinician's retention plan is fully discussed at the beginning of your treatment - no surprises in the end that way & you're going into Invisalign with both eyes wide open!
Which will ultimately keep you SMILING wide open for evermore...
it is YOUR responsibility.
