Bone grafting is a surgical procedure that adds bone or bone-substitute material to your jaw where bone has been lost. The graft provides a scaffold that your body gradually replaces with your own living bone. This is most commonly done to rebuild the jaw for dental implant placement, but it is also used after extractions, to repair defects from cysts or infections, and to restore ridge contour for dentures.

Four sources are used in dentistry. Autograft: your own bone, harvested from the chin, ramus, or hip. Allograft: processed human donor bone from a tissue bank. Xenograft: processed bovine or porcine bone. Synthetic: lab-manufactured calcium phosphate or hydroxyapatite. We most commonly use allograft and xenograft materials, with autogenous grafts reserved for large defects requiring living bone cells.

The procedure itself is painless — it is performed under local anesthesia, with IV sedation available. Post-operative discomfort varies by the size of the graft. Small socket grafts produce minimal additional pain beyond the extraction itself. Larger ridge augmentation or block graft procedures involve more swelling and discomfort, managed effectively with anti-inflammatory medication and, when needed, a short course of prescription pain medication.

Soft tissue healing occurs within 2-3 weeks. The bone graft itself matures over 4-6 months as your body gradually replaces the graft scaffold with living bone through a process called creeping substitution. A follow-up CBCT scan is taken before implant placement to confirm adequate bone volume and density.

Sometimes. If the bone defect is small and enough native bone exists to stabilize the implant initially, we can place the implant and graft simultaneously. This is common with socket grafts and minor GBR procedures. Larger defects — significant ridge augmentation, block grafts, sinus lifts with minimal residual bone — typically require the graft to heal first, then implant placement as a second procedure.

Bone grafting is highly predictable when performed with proper technique. Success rates for socket preservation grafts exceed 95%. Ridge augmentation and sinus lifts performed by experienced surgeons also have success rates above 90-95%. Factors that reduce success include smoking, uncontrolled diabetes, infection at the graft site, and premature loading of the graft.

The most common causes of graft failure are infection, membrane exposure (loss of primary closure), instability of the graft (micro-movement), smoking, and poor blood supply to the site. This is why surgical technique is critical — achieving tension-free primary closure, stabilizing the graft, and using PRF to enhance vascularization all reduce the risk of failure.

Not always. If you plan to replace the tooth with an implant, a socket preservation graft is strongly recommended. If you are not replacing the tooth and it is not in a cosmetically critical area, grafting may not be necessary. We discuss the pros and cons of grafting at the time of every extraction based on your individual treatment plan.

PRF (platelet-rich fibrin) is a blood concentrate made from your own blood that is rich in growth factors essential for healing. We mix PRF with the graft material and place PRF membranes over the graft site. This concentrates growth factors at the graft, improves vascularization, accelerates soft tissue closure, and enhances the biological environment for new bone formation.

Cost varies widely based on the type and size of the graft. A small socket preservation graft may cost $400-800. Ridge augmentation and GBR procedures range from $1,500-4,000. Sinus lifts range from $1,500-3,500. Block grafts are typically $2,000-5,000. Many dental insurance plans cover a portion of bone grafting when it is medically necessary. We provide exact estimates after your CBCT evaluation.

Yes, in most cases. Osteoporosis affects bone density but does not prevent bone graft healing. However, if you take bisphosphonate medications (especially IV bisphosphonates), there is an increased risk of medication-related osteonecrosis of the jaw (MRONJ). We carefully review your medication history and may consult with your physician before proceeding.

A socket graft fills the empty tooth socket at the time of extraction to prevent bone collapse — it is preventive. Ridge augmentation rebuilds bone that has already been lost — it is corrective. Socket grafts are simpler, faster, and less expensive. Ridge augmentation is a more involved surgical procedure with longer healing times.

Yes. Allograft bone from tissue banks undergoes rigorous screening, processing, and sterilization. The risk of disease transmission is estimated at less than 1 in 1.6 million — lower than many commonly accepted medical risks. The bone is freeze-dried and irradiated, removing all living cells and pathogens while preserving the mineral scaffold and growth factor proteins.

A CBCT scan is the definitive diagnostic tool. It shows the three-dimensional volume, height, and width of your available bone. If the bone is insufficient for the planned implant diameter and length — or if the ridge is too narrow or too short — bone grafting is needed. We measure this precisely during your consultation.

Yes. Even if significant bone loss has occurred over years of being without the tooth, ridge augmentation and GBR can rebuild the bone. The grafting may be more extensive than if it had been done at the time of extraction, and it may add time to the overall implant timeline, but the bone can still be rebuilt.
