When you lose a tooth, the bone beneath it can begin to shrink over time. A thin or soft ridge may not hold an implant securely, which is worth knowing if you are considering a replacement.
A bone graft is a procedure that adds material to the jaw, helping restore enough strength and shape for your dentist to place an implant there.
How Bone Loss Can Affect Dental Implant Placement
An implant relies on osseointegration, the process by which bone tissue grows around a titanium post and secures it. When there isn’t enough bone volume or density, that fusion may not fully occur, and the implant can become loose or fail over time, which may mean discomfort while chewing or the need for further treatment later on.
Not everyone needs a graft before treatment. Many dentists include imaging as part of implant planning to check jaw volume beforehand, and they may recommend a graft when the bone doesn’t appear sufficient to support an implant.
7 Common Reasons You Might Need a Bone Graft
Bone loss often develops without any visible sign or sensation. Several factors can contribute to it. The following is what a dentist generally evaluates, and why each factor can shape the treatment plan.
Insufficient Jawbone Volume or Density
Some patients have less available bone mass, shaped by genetics, age, or years spent without a tooth in that area. An implant generally needs a certain amount of solid bone around it to stay anchored, so a graft may help add bone volume where it is insufficient.
Gum Disease–Related Bone Loss
Advanced gum disease can affect the bone beneath the gums, frequently without obvious symptoms in its early stages. Many patients do not realize how much bone support they have lost until an evaluation for a dental implant. In general, dentists address active gum disease before planning any grafting, since treating it first supports a more predictable healing outcome.
Bone Deterioration From Tooth Loss or Extraction
Bone usually stays dense partly because of the pressure it receives from chewing, and a missing tooth removes that stimulation. This can contribute to bone loss in that area over time, which is one reason a dentist sometimes recommends grafting after an extraction.
Long-Term Denture-Related Bone Resorption
Dentures rest on the gums rather than engaging the bone the way a natural tooth root does. Over years of wear, this can result in gradual bone loss beneath the denture. Patients who have worn dentures for a long time and are considering implants may need grafting to rebuild that area first.
Naturally Thin or Shallow Jawbone Anatomy
Some patients naturally have a narrow or shallow ridge, leaving insufficient bone volume for the planned implant. A dentist usually identifies this through imaging completed before treatment.
Jawbone Damage From Previous Trauma
A fracture, injury, or past oral surgery can sometimes leave the jawbone uneven or reduced in that area, even after the injury has fully healed. Grafting can help correct these irregularities when necessary.
Limited Bone Height Near the Upper-Jaw Sinuses
In the upper back jaw, the sinus cavity lies close to where a dentist would place an implant. When there isn’t enough bone between the ridge and the sinus floor, a dentist may perform a sinus lift procedure alongside the graft.
This procedure raises the floor of the sinus and adds bone in that space, helping create enough height to support an implant safely.
How Bone Grafting Supports a Long-Term Result
Bone grafting adds new material to the jaw, so the missing volume has a chance to rebuild. Where that material comes from depends on the case. Some bone grafts use bone taken from elsewhere in the patient’s own body; others use donor material or synthetic substitutes.
Healing takes time, and it looks different for every patient. Some mild swelling or discomfort in the days after the procedure is common, and most patients can resume normal activities within a few days.
Full healing generally takes several months before a dentist can place an implant, since the graft needs time to fully integrate with the existing bone before it can offer a sturdier base.
