Bone Grafting for Dental Implants: What to Expect

Why Bone Grafting Is Sometimes Necessary

When you lose a tooth, the bone that supported it begins to resorb. Your jawbone resorbs relatively quickly in the first year after tooth loss and then continues to decrease over years. If you’ve had a missing tooth for several years, significant bone loss has likely occurred.

Dental implants require adequate bone height and width to be placed successfully. If your bone is insufficient, a graft can rebuild it. This additional step takes time and adds cost, but it enables many patients who wouldn’t otherwise be candidates for implants to receive them successfully.

Bone might also be lacking if you’ve had gum disease that destroyed bone, if you’ve had a tooth extraction that was traumatic, or if you’ve worn dentures for years. Dentures don’t stimulate bone the way tooth roots do, so bone loss accelerates under dentures.

Types of Bone Grafts

Autogenous bone (bone from your own body) is ideal for grafting. It has the best success rates because your body recognizes it as your own and integrates it readily. Bone can be harvested from your own jaw, your hip, or another area of your body. However, this requires an additional surgical site, which adds time and discomfort to the procedure.

Allogeneic bone is bone from a human donor. This bone has been processed and sterilized. Your body doesn’t recognize it as foreign if it’s been properly processed, and it integrates well. Using donor bone eliminates the need for a second surgical site to harvest bone.

Xenogeneic bone comes from an animal source, typically bovine (cow) bone. This bone has been processed to remove the organic components, leaving behind the mineral structure. Your body replaces it with your own bone over time. Xenogeneic bone is widely available and successful.

Synthetic bone substitutes are engineered materials designed to mimic natural bone. These materials are biocompatible and support new bone formation. They might be used alone or combined with other graft materials.

Your oral surgeon selects the material best suited to your case, and Dr. Bonin reviews that choice with you as part of the overall plan. All have good success rates. The choice depends on the amount of bone needed, your preferences, and your situation.

The Bone Grafting Procedure

Bone grafting is oral surgery, so it is not done at our Windsor office. Dr. Bonin is a general dentist. He takes the imaging, identifies how much bone is missing and where, and refers the graft to a trusted oral surgeon or periodontist. He then coordinates the timing against your restorative plan so the graft, the implant, and the final crown all line up. You get a surgeon who does this work every day, and one office keeping the whole case on track.

Before the graft, imaging studies determine exactly how much bone is needed and where it should be placed. This planning ensures the graft is placed precisely where it’s needed.

Your oral surgeon places the graft. If using your own bone, a second surgical site is created to harvest it. If using donor bone or synthetic material, no second surgery is needed. The graft material is placed in the area where bone is lacking, then the area is covered with a membrane that holds the graft in place and keeps it protected while new bone forms.

The procedure is usually done under local anesthesia, though some patients choose sedation to be more comfortable. The procedure typically takes 1 to 2 hours depending on the extent of grafting needed.

Healing and Timeline

Initial healing takes about 1 to 2 weeks. You’ll have some swelling, bruising, and mild discomfort during this time. Your oral surgeon prescribes pain medication and provides detailed post-care instructions.

During the first couple weeks, you’ll want to avoid strenuous activity and eat soft foods. You’ll need to be careful around the graft site when brushing and flossing. Some special rinses might be recommended to keep the area clean.

Bone integration takes longer. The grafted material acts as a scaffold that your body uses to build new bone. This process typically takes 4 to 6 months. After this healing period, imaging studies are taken to confirm that the bone has integrated and is ready for implant placement.

Some cases require longer healing times. Your surgeon assesses how the graft is healing, and Dr. Bonin tells you what that means for the rest of your timeline.

Success Rates

Bone grafts have high success rates, typically 85 to 95 percent or higher. Autogenous bone has the highest success rates. Allogeneic and xenogeneic bone grafts also have excellent success rates.

Multiple factors affect success. Your overall health, your commitment to post-operative care, and your bone healing ability all matter. Smoking and poor oral hygiene decrease success rates.

If a graft doesn’t integrate successfully, another grafting attempt is usually possible. Implant placement might be delayed, but alternatives remain available.

Implant Placement After Grafting

After bone grafting, you wait for integration and healing. Once imaging confirms that bone has adequately regenerated, your oral surgeon can place the implant. This is a separate procedure done after the graft has healed.

The surgeon might place the implant soon after bone integration is confirmed, or wait a bit longer depending on the specifics. Dr. Bonin coordinates that timing against your restorative plan so nothing sits idle.

After implant placement, another healing period occurs while bone integrates around the implant. This typically takes 3 to 6 months. Once osseointegration is complete, the implant is ready for restoration, and Dr. Bonin designs and seats the final crown at our Windsor office.

Managing Pain and Discomfort

Most patients report that bone grafting is less uncomfortable than they anticipated. Post-operative discomfort is usually mild to moderate and managed well with over-the-counter or prescribed pain medication.

Swelling is normal and peaks around day 2 to 3. Ice helps reduce swelling during the first 48 hours. Elevation and rest help as well.

Most patients return to light activity within a few days and regular activity within a couple weeks. Strenuous exercise and contact sports should be avoided for about 4 to 6 weeks.

Cost Considerations

Bone grafting adds cost to the overall implant process. The amount depends on the type of graft material used and the extent of grafting needed. Your dentist provides a cost estimate during your consultation.

While grafting adds upfront cost, it enables implant placement in situations where it wouldn’t otherwise be possible. Implants are a long-term investment that restores function and prevents continued bone loss.

Is Grafting Right for You?

If you’re missing teeth and bone loss has made you ineligible for implants, grafting might make implant placement possible. During your consultation, Dr. Bonin at Bonin Dental Care evaluates your bone and discusses whether grafting would benefit you.

Not every patient needs grafting. Some have adequate bone without it. Others decide to pursue alternative restorative options like dentures or bridges. The goal is helping you understand your options and make the decision that’s best for your situation.

Dr. Bonin can evaluate your bone, walk you through the full process, timeline, and cost involved, coordinate the graft and the implant placement with a trusted oral surgeon, and restore the implant with your final crown.
