Bone grafting rebuilds jawbone that has thinned or shrunk so that a dental implant has enough healthy bone to anchor into. When a tooth has been missing for a while, the bone that once held its root gradually resorbs, and the site may no longer be wide or tall enough to hold an implant securely. A graft restores that volume, giving the implant a stable foundation that supports long-term function.
At Legacy Oral Surgery & Implants, our oral and maxillofacial surgeons provide bone grafting as part of a complete oral surgery and implant treatment plan, so the same team that evaluates your bone also plans and places your implants. This guide focuses on a question patients often ask once they hear the word “graft”: where does grafting fit in the implant timeline, and how does it change the schedule for your new teeth? Our surgical team plans these steps for patients at our Union City, Elizabeth, and Staten Island offices.
Why Jawbone Loss Happens After Tooth Loss
The jawbone depends on stimulation from tooth roots to maintain its shape and density. When a tooth is extracted or lost to disease, the bone that surrounded that root no longer receives this stimulation and begins to resorb. A 12-month prospective study of extraction sites by Schropp and colleagues found that the major changes to the bone and gum contour happen during the first year after extraction, which is why the timing of grafting and implant placement matters so much.
Bone loss is also accelerated by periodontal disease, which erodes the bone supporting teeth from within. Facial trauma, infection, and long-term denture wear contribute as well. In each of these situations, a bone graft may be recommended before or during implant placement to restore the volume and density needed to hold an implant securely.
Types of Bone Graft Materials
Several types of grafting material may be used depending on the size of the defect, its location in the jaw, and your overall health. Your oral surgeon will explain which material is most appropriate for your situation.
Autografts use bone taken from another location in your own body, most often another area of the jaw. Because the material is your own, autografts have excellent biological compatibility and may be preferred for larger defects. They do require a second surgical site, which can add some recovery time.
Allografts use processed bone from a tissue bank. The material is sterilized and processed to reduce disease risk while preserving the mineral structure that guides new bone growth. Allografts are widely used and avoid the need for a second harvest site.
Xenografts are derived from animal sources, most commonly bovine (cow) bone, and are processed in a similar way. They act as a scaffold that your own bone cells grow into over time.
Alloplasts are synthetic bone substitutes made from materials such as calcium phosphate compounds or bioactive glass. Because they are man-made, they carry no risk of disease transmission. Alloplasts are often used for smaller defects or combined with other materials.
When Grafting Happens in Your Implant Timeline
Grafting is not a single event that always happens at the same point. Depending on your bone, your surgeon may graft at the time of extraction, in a separate procedure months before the implant, or during the same appointment as implant placement. Each approach changes how long your overall treatment takes.
At the Time of Extraction
When a tooth is removed, the empty socket begins to change shape as it heals. Socket preservation places grafting material directly into the extraction site right after the tooth comes out to help maintain the socket’s dimensions. This proactive step can keep the ridge in better condition for a future implant and may reduce the need for more extensive grafting later. If you know a tooth needs to come out and you are considering an implant, ask about socket preservation before the extraction is scheduled.
A Staged Graft Before the Implant
When bone loss has already occurred and the ridge has narrowed or flattened, your surgeon may rebuild it first and place the implant later. Ridge augmentation adds grafting material along the deficient area, usually covered by a membrane that guides new bone growth. In the upper back jaw, where the sinus can sit close to the ridge, a sinus lift gently raises the sinus membrane and places graft material beneath it to add height for implants. Staged grafting adds months to the timeline, but it can make implant placement possible in sites that would otherwise be too thin.
Grafting at the Same Time as Implant Placement
When the implant can still be anchored firmly in existing bone but a small area needs reinforcement, the surgeon may place graft material around the implant during the same procedure. This can save a separate surgery and shorten treatment. Whether it is an option depends on how much stable bone is available at the site, which is assessed on three-dimensional imaging during your consultation.
Recovery and Healing Timeline
The healing period after a bone graft is an important phase of the implant process, and knowing what to expect helps you protect the result.
Most patients experience mild to moderate discomfort for several days after bone graft surgery, which is usually manageable with prescribed or over-the-counter pain relief as directed by your surgeon. Swelling and bruising are normal and generally peak around two to three days before subsiding. A soft-food diet and rest during the first week support early healing.
According to the Cleveland Clinic, initial recovery takes about a week, but the graft itself needs at least three months to heal, and a large graft may take nine to 12 months. Your oral surgeon will confirm readiness through a clinical exam and imaging rather than a fixed calendar date. Avoiding smoking and following your aftercare instructions directly affects how well the graft integrates.
Timing matters on the other end of the process as well. The Cleveland Clinic advises that once a bone graft heals, it is best to place the implant within six to 12 months, because the new bone can otherwise begin to shrink and lose density. If you are planning around work, travel, or other procedures, discuss the full schedule with your surgeon before grafting begins. Once the implant is placed, the next phase is covered in our guide to the stages of dental implant healing.
Success Rates and What Affects Them
Bone grafting for implant preparation has a strong track record. The Cleveland Clinic reports success rates of up to 100%, depending on the type of graft, while noting that failure is possible, especially among people who smoke or have certain medical conditions. Several factors influence outcomes:
- Patient health: Smoking and poorly controlled conditions such as diabetes can impair healing and raise the risk of graft failure
- Surgical technique: Careful graft placement and stabilization support integration with your own bone
- Graft material selection: Matching the material to the size and location of the defect affects how well the graft incorporates
- Postoperative care: Following instructions and attending follow-up visits allows your surgeon to monitor and protect the graft site
Patients who do not smoke, keep chronic conditions under control, and follow their care instructions give the graft the best chance to succeed. If any of these factors apply to you, tell your surgeon during the consultation so the plan can account for them.
When a Graft May Not Be the Only Option
Not every implant candidate needs a bone graft. Patients who pursue implant placement soon after tooth loss, or who still have adequate bone volume, may be able to proceed directly to implant placement. During your consultation, our surgeons review three-dimensional imaging of your jaw to assess bone volume at each planned implant site.
When bone loss is significant, there may also be alternatives or companions to grafting. In the lower back jaw, nerve repositioning is one option our practice offers for selected cases with limited bone above the nerve. Full-arch approaches such as All-on-4 can sometimes use angled implants to make use of the bone that remains. Our article on whether you can still get dental implants with severe bone loss walks through these options in more detail, and our post on the benefits of bone grafting explains why preserving bone matters even beyond implants.

Frequently Asked Questions About Bone Grafts for Dental Implants
How long does a bone graft take to heal before implant placement?
Initial recovery usually takes about a week, but the graft itself generally needs at least three months to heal, and larger grafts may take nine to 12 months. The exact time depends on the type of graft, the size of the defect, and your overall health. Your oral surgeon will confirm readiness with an exam and imaging rather than assuming a fixed date.
Can a bone graft and a dental implant be done at the same time?
Sometimes. When the implant can still be anchored firmly in existing bone and only a small area needs reinforcement, graft material can be placed around the implant during the same procedure. When bone loss is more extensive, a staged approach is usually safer, with the graft healing for several months before the implant is placed. Three-dimensional imaging at your consultation helps determine which approach fits your situation.
Is a bone graft always required before getting dental implants?
No. Patients who have enough bone volume at the implant site can often proceed directly to implant placement. A graft is recommended when imaging shows the jawbone has resorbed to the point where it cannot reliably support an implant. The need for grafting is decided case by case during your consultation.
What are the different types of bone graft materials?
The four main types are autografts, which use your own bone, allografts, which use processed donor bone from a tissue bank, xenografts, which use processed animal bone, most commonly bovine, and alloplasts, which are synthetic materials such as calcium phosphate. Each has specific uses depending on the size and location of the defect, and your surgeon will recommend the most appropriate material for your case.
Does a bone graft hurt?
The procedure is performed with local anesthesia, so you should not feel pain during surgery, and sedation options are available for patients who prefer them. Afterward, mild to moderate discomfort for several days is normal and is usually manageable with the pain relief your surgeon recommends. Swelling and bruising typically peak around two to three days and then subside.
What happens if I wait too long after a bone graft to get my implant?
Grafted bone needs the stimulation of an implant to stay healthy. The Cleveland Clinic advises placing the implant within six to 12 months after the graft heals, because the new bone can otherwise begin to shrink and lose density. If your plans change, talk with your surgeon about timing so the volume gained from the graft is not lost.
