If you have been told that you do not have enough bone for a dental implant, a bone graft may help make treatment possible. Although the term can sound daunting, bone grafting is a routine procedure that helps rebuild the jawbone and create a stable foundation for dental implants.
Understanding how a missing tooth can affect your oral health may help you make informed decisions about how to replace it and what the best option is.
What Is a Bone Graft?
A bone graft is a procedure used to rebuild or increase the volume of bone in the jaw, especially in implant cases where there is not sufficient bone quality to support implant placement.
The grafting material is placed in an area where bone has been lost or where additional support is needed. Over time, the body incorporates the graft material and develops new bone around it.
Think of it as the foundation needed before building a house. Without adequate support underneath, even the best structure above may not perform as intended.
Why Is Bone Needed for Dental Implants?
Almost every dental implant is placed directly into the jawbone, where it acts as an artificial roots.
For an implant to be successful, there must be sufficient bone height, width and density to hold it securely. If bone levels are inadequate, implant placement may be difficult or impossible without additional treatment. Therefore, a bone graft helps restore the lost bone and improve the long-term stability of the implant.
Why Does Bone Loss Happen?
The roots of natural teeth stimulate the jawbone whenever you chew. Once a tooth is lost, that stimulation disappears, and the body gradually begins to resorb the bone in that area. Also, the longer a tooth has been missing, the more likely it is that bone loss has occurred.
Other causes of bone loss include:
Gum disease
Dental infections
Trauma or injury
Denture wear
Certain medical conditions
How Do Dentists Determine If a Bone Graft Is Needed?
Before every dental treatment, our team will carry out a detailed assessment of your mouth.
This appointment usually includes a full clinical assessment, digital X-rays, and 3D CBCT scanning. All this information allows our team to accurately measure the available bone and determine whether additional grafting is required.
In consequence, many patients who are told they have insufficient bone volume or density for dental implant placement are still able to proceed with the treatment after the appropriate grafting techniques.
What Materials Are Used for Bone Grafts?
Several different grafting materials may be used depending on the clinical situation. Some of them are:
Synthetic Bone Materials
Many modern bone grafts use highly biocompatible synthetic materials designed to support natural bone growth.
Donor Bone
Processed donor bone may be used in some situations. This material is carefully prepared and sterilised to meet strict safety standards.
Animal-Derived Bone Grafts
Certain grafting materials are derived from natural sources and act as a scaffold to encourage new bone formation.
Either way, our specialists will explain which material is most appropriate for your individual treatment plan.
What Happens During the Procedure?
The exact procedure depends on the amount of bone required and the location being treated:
In most cases, the area is thoroughly numbed with a local anaesthetic.
The grafting material is then carefully placed into the deficient area and protected with the specialised membranes whenever necessary
Once completed, the gum tissue is closed using sutures
Many patients are relieved to discover that the procedure is often more straightforward than they expected.
Can Bone Grafting Be Done at the Same Time as Implant Placement?
Sometimes, yes. If only a small amount of additional bone is required, the dentist may be able to place the implant and bone graft during the same procedure.
However, in most complex cases, the graft may need to heal first before the implant can be placed. This decision depends on multiple factors, such as bone volume, implant stability and location of the missing tooth.
Recovery After Bone Grafting?
The recovery after this procedure is usually manageable for most patients. However, there are also some common temporary side effects that include:
Mild swelling
Bruising
Tenderness
Minor bleeding
These symptoms generally improve over a few days, and most patients can return to normal daily activities in a short time.
Are There Any Risks?
As with any surgical procedure, bone grafting carries some potential risks, which may include infection, delayed healing, swelling, discomfort or graft failure.
Fortunately, severe complications are uncommon, particularly when treatment is carried out by experienced clinicians and patients follow aftercare advice carefully.
