Adding to the time of doing an implant: If the in-jaw portion cannot be done at the same time as the extraction, you have to wait a few months for the bone to heal enough to accept the implant. With my first, I didn’t even decide which approach to do until a year or more after the tooth was yanked; the advantage there was I did not require any kind of bone graft as I had plenty of my own. With the second, I planned on an implant right off the bat before the extraction, so the discussion with the oral surgeon was something like this:
“Can you place the implant at the same time you yank it?”
“Maybe… won’t know for sure until I get in there; if I do, you’ll need some bone grafting”
“OK - you use your judgment and tell me what you did when I come out of the sedation”
I was lucky; he WAS able to do both at the same time, though as I recall it meant there were a lot more of those annoying-as-hell dissolvable stitches in my gum. And, the post of the implant stuck above the gumline (with the first one, it was all covered; he then had to uncover it before the crown was made).
As a hint for anyone considering an implant: Once that part is done, your regular dentist makes a crown - which is as expensive as having an existing tooth crowned. If your dental insurance has a maximum yearly benefit, time things so that the implant is done in one year and the crown in another.
