Ridge augmentation is a surgical procedure that rebuilds the jawbone ridge after it has resorbed due to tooth loss, trauma, or infection. Bone graft material is placed along the deficient ridge and secured with a membrane. Over four to six months, the graft integrates and creates enough bone volume for dental implant placement.

After tooth loss, the alveolar bone resorbs naturally because it no longer receives stimulation from tooth roots. Without socket preservation at the time of extraction, the ridge can lose 50 percent of its width within a year. Ridge augmentation restores this lost volume so the ridge can support an implant.

Graft maturation takes four to six months. Soft tissue heals within two to three weeks. The bone graft needs this time to vascularize, integrate with your native bone, and achieve adequate density. A CBCT scan at four to six months confirms the site is ready for implant placement.

The procedure is performed under local anesthesia or IV sedation, so you feel nothing during surgery. Post-operative discomfort is moderate — similar to a tooth extraction — and is managed with prescribed or over-the-counter pain medications for three to five days. Swelling peaks at day two or three and resolves within a week.

Options include autograft (your own bone), allograft (donor human bone), xenograft (bovine-derived mineral), and synthetic bone substitutes. Each has advantages: autograft has the highest osteogenic potential, allograft and xenograft provide excellent scaffolds without a donor site. Dr. Ostovar selects the material based on the defect size and your specific needs.

Ridge augmentation typically costs $1,500 to $4,000 per site, depending on the defect size, graft material, and membrane type. Large defects requiring block grafts or titanium-reinforced membranes cost more than small particulate grafts with collagen membranes. Exact costs are provided in your treatment plan.

In some cases, yes. If the existing bone can provide primary stability for the implant and the graft is supplemental (filling a gap or thickening the buccal plate), both can be done simultaneously. If the bone is too deficient for any implant stability, staged grafting first is safer.

The most common complication is membrane exposure, which occurs when the gum tissue opens over the graft. This can compromise the graft if not managed promptly. Infection, graft loss, and incomplete bone fill are also possible but uncommon with proper surgical technique. Smoking significantly increases all complication risks.

A titanium-reinforced membrane is a non-resorbable barrier that maintains its shape under soft-tissue pressure, preventing the gum from collapsing into the graft space. It is used for large defects where space maintenance is critical. It requires a second minor procedure for removal at four to six months, but it provides the most predictable results for significant augmentation.

Socket preservation fills a fresh extraction socket to prevent bone loss. Ridge augmentation rebuilds bone that has already been lost. Socket preservation is simpler, less expensive, and heals faster. Ridge augmentation is more invasive but can restore significant bone volume. Socket preservation at the time of extraction often prevents the need for ridge augmentation later.

Yes, though failure rates are low (5 to 10 percent) with experienced surgeons. Failure typically manifests as membrane exposure with subsequent graft infection or incomplete bone fill. If failure occurs, the site is debrided, allowed to heal, and a second grafting attempt can be made. Smoking is the single greatest risk factor for failure.

Some dental insurance plans cover bone grafting when it is part of an implant treatment plan, typically at 50 percent. Medical insurance may cover grafting if it is related to trauma or pathology. Coverage varies significantly by plan. Our team verifies your benefits before treatment.

Avoid chewing on the grafted side, do not smoke, and eat soft foods for two to three weeks. Gentle rinsing with chlorhexidine mouthwash is recommended starting 24 hours after surgery. Do not brush directly over the surgical site for one week. Take all prescribed medications, including antibiotics if provided.

No. The graft is placed beneath the gum tissue and covered with sutures. You may feel some firmness under the tissue as the graft heals, but nothing is visible. Once healing is complete and the implant and crown are in place, there is no outward indication that grafting was performed.

Ridge augmentation can typically add 3 to 6 mm of horizontal width and 2 to 4 mm of vertical height. For larger defects, block grafts or staged augmentation procedures may be needed. The achievable volume depends on the defect geometry, blood supply to the area, and the graft technique used.
