An implant is only as stable as what surrounds it. That’s why the question at a consultation isn’t just whether you want one — it’s whether the site can hold one yet, and what it takes to get there if not.
What “enough bone” means
An implant needs bone on every side of it, not simply underneath. That means adequate height and adequate width, plus safe clearance from the structures nearby — the nerve running through the lower jaw, and the sinus above the upper back teeth. A ridge can look perfectly normal from the outside and still be too narrow to hold a post, which is why this is assessed with imaging rather than by eye.
The American Association of Oral and Maxillofacial Surgeons is explicit that implant placement may require hard-tissue or soft-tissue grafting, and that both the material and the technique vary with the degree and type of the deficiency. There is no standard graft, because there is no standard defect.
The three situations that come up most
Socket preservation — graft material placed into the socket at the time the tooth comes out. It doesn’t treat a problem so much as prevent one, holding the volume that would otherwise be lost over the following months. It is by far the cheapest form of bone grafting, because it’s the one you don’t have to do twice.
Ridge augmentation — rebuilding width or height on a ridge that has already flattened. This is the common situation when a tooth has been missing for years and the site now has to be restored before it can be used.
Sinus lift — in the upper back jaw the sinus floor sits close above the tooth roots, and it tends to drop further once those teeth are gone. A sinus lift raises that floor and places graft material beneath it to create the height an implant requires.
Soft-tissue grafting is sometimes part of the picture too. Bone determines whether an implant is stable; the gum tissue around it determines a good deal of how the finished result looks and holds up.
How the sequence works
Smaller grafts can often be placed at the same appointment as the implant, or alongside an extraction. Larger reconstructions generally can’t — the graft has to heal and turn into usable bone before anything is anchored into it, which stages the treatment across months rather than weeks.
That timeline is set by biology, not scheduling. It’s worth knowing early, because it’s the part that most often surprises people who came in expecting a single procedure. The plan you leave your consultation with should tell you which pathway you’re on and roughly how long it runs.
If you’ve been told implants aren’t possible
It happens often, and it’s frequently a statement about the current state of the site rather than about you. Significant bone loss, difficult anatomy, and implants that failed in another office are a substantial share of the cases referred here. Dr. Janette is a board-certified oral and maxillofacial surgeon whose residency training covered bone grafting and implant placement together, and the surgical placement is coordinated with your own dentist for the restoration.
Whether that changes your answer depends entirely on what the imaging shows. But a second opinion is worth having before accepting that nothing can be done.
Common questions
No. Plenty of sites have enough bone already, particularly when the tooth was lost recently. Grafting becomes more likely the longer a space has been empty, or when the tooth was lost to infection, gum disease or injury.
Sometimes. Smaller grafts can be placed alongside the implant, and graft material is often placed into a socket at the time of an extraction. Larger reconstructions usually need to heal first, which stages the treatment.
In the upper back jaw the sinus sits close above the roots, and after tooth loss there’s often too little bone height beneath it. A sinus lift raises that floor and adds graft material to create the height an implant needs.
Most patients compare a smaller graft to an extraction: sore for a few days and manageable. Larger reconstructions ask more. Discomfort should ease steadily, and pain that eases then returns is a reason to call the office.
It depends on your plan, and on whether the case has a medical component. We identify your coverage before your consultation, help you navigate your dental benefits, and give you a written estimate before treatment begins.
