Oooh - not long now :)
I don't know if you've had stitches or not, but I did, so I had to go back a week or so later to have them removed; then another 2 weeks or so before the impressions were taken. (I've kept a copy of all my appointments and costs, along with squillions of photos).
When your impressions are taken, the abutments will be attached to the implant. This is a metal post that screws in to the implant and the crown will be attached to this with a "cement". These abutments will only be in place for the impression and will be removed after the impression has been taken.
Then it's a final wait of approx 2-3 weeks for the final fitting :)
I'm only going off what I went through, so your treatment may be slightly different.
Good luck ......
