Dental Implant Bone Graft

A bone graft rebuilds jawbone that has been lost — either to long-term tooth absence, periodontal disease, or trauma — so that an implant can be placed in adequate bone. About 40% of implant cases at our practice need some form of grafting.

Grafting adds 3–6 months to the timeline and $1,500–$4,000 to the cost depending on the volume and technique. It makes implants possible for patients who would otherwise be told no.

The moment a tooth root leaves the jaw, the surrounding bone begins to resorb. CT studies show 25% width loss in the first year alone and another 5–10% over the next four years. After 5+ years without a replacement, the bone at that site is often too thin or too short for a standard implant.

Periodontal (gum) disease actively destroys bone around still-present teeth. Patients who lose teeth to gum disease arrive with both missing teeth and missing bone in the surrounding ridge.

Long-term denture wear accelerates ridge atrophy because dentures load bone in the wrong pattern. Decade-long denture wearers often have severe bone loss.

Ground bone particles — either from a tissue bank (allograft) or synthetic (alloplast) — packed into the deficient area and covered with a resorbable membrane. The graft acts as a scaffold for your own bone cells to regrow into.

Healing takes 4–6 months. During that window, your body remodels the graft into living bone. We image the site at the 4-month mark to confirm adequate bone volume, then place the implant.

About 70% of our bone-loss patients are restored with particulate grafts alone. Cost is $1,500–$3,000 per site depending on volume.

When the ridge is severely deficient (more than 5–6 mm of vertical or horizontal loss), a particulate graft alone may not rebuild enough volume. A block graft takes a thin slice of bone — usually from the back of the lower jaw (ramus) — and screws it onto the deficient site.

Block grafting requires two surgical sites and a longer recovery (5–7 days of moderate discomfort). Healing takes 6 months before implant placement is possible. Cost is $3,000–$5,000 per block site.

We perform block grafting when particulate grafts won't deliver the needed volume. For most cases, particulate is the first choice.

When the ridge is too thin (less than 4 mm wide) but tall enough for an implant, ridge expansion uses specialized chisels to gently split the thin ridge in half, creating a channel that accommodates the implant immediately. Bone graft material is packed around it.

The advantage is that implant placement can happen at the same surgery as the expansion — no separate healing period. Recovery is similar to standard implant placement.

Ridge expansion adds $800–$1,500 to the implant cost and adds 30–45 minutes to the procedure.

Particulate grafting recovery is similar to implant surgery alone: 48 hours of mild discomfort, controlled with ibuprofen and Tylenol. Most patients return to a desk job at 48 hours and to the gym at one week.

Block grafting recovery is longer because of the donor site (where bone was harvested). Plan on 5–7 days of moderate discomfort and 2 weeks before returning to vigorous physical activity. The donor site is sometimes more sensitive than the recipient site.

For both, avoid touching the surgical site, rinse gently with warm salt water, and avoid hard or crunchy foods for at least 2 weeks. Smoking dramatically reduces graft success — we strongly recommend stopping during the healing window.

Particulate graft success rate is 90–95%. Block graft success rate is 85–90%. When a graft fails to take, the site is allowed to heal for 3–6 months and a second graft is attempted. Second-attempt success is in the same range as first-attempt.

The biggest single predictor of graft success is smoking status. Non-smokers see the high end of success ranges; heavy smokers see the low end. Stopping for the healing window matters.
