Bone Graft Failure: Three months ago my dentist extracted two upper molars and did two sinus lifts and bone grafting.
She called me in early this month for a check-up and said both sinus lifts and bone grafting would have to be repeated because bone growth was insufficient.
Is 14 weeks time enough to ascertain whether bone growth is proceeding satisfactorily? I expected to wait four to six months before evaluating bone growth. ...Visitor from TX
Three months is sufficient time to determine if there is enough volume of bone to place implants where the bone grafts and sinus lifts were done.
Waiting longer might improve the density of the bone but would not increase the amount of bone present.
For example, an implant may be ten millimeters long and after your last treatment maybe there is only seven millimeters of bone height so more will be needed.
It is unfortunate that you may need another procedure to be able to place implants, but to put them in when there is not enough volume of bone present would only lead to other problems and the implants most likely will fail.
