Consult your oral surgeon
2nd opinions are
never a bad thing, but your oral surgeon is one of the best people to ask when
it comes to anything about bone structure around an implant. You would hate to
invest in your implant and have it fail, simply because there isn’t enough bone
in the area. You might also ask your dentist about how much bone was placed,
although it is possible that the graft just didn’t take as he expected it
With that amount
of money, you can even get an implant, and yes there are some times where bone
will necessarily need to be added, as long as the doctor and patient are
satisfied with the goals and results. It can happen, depends on each specific case.
Depending on the KIND of graft, there is often some shrinkage. This means we often build out a large volume of bone so that what remains is "enough". If we place "just enough" the shrinkage/healing leaves us shy of what is needed. Without seeing what we have to work with, I can't say if you do or don't need another graft. Second opinions are never a bad idea, but odds are you are in good hands.
