Should you go back and re tighten implant screws?

Farina 2012 from JOMI recommends re-tightening screws at 6 month post insertion.  With my protocol found here I am comfortable with just replacing them at 1 year.

Update on that.  Don’t mess with them unless a problem.  When delivering it is a good idea to tighten everything down, wait 15 minutes and re-tighten 4/26/14.
