Bone Grafting for Dental Implants

If your dentist recommends a dental implant to replace missing teeth, you may need a bone graft before your procedure. In this post, our Edmonton dentists explain bone grafting for dental implants.

Bone Grafts & Dental Implants

If you are generally healthy and lose a tooth to trauma, infection, periodontal disease or something else, your dentist may recommend a dental implant to replace the lost tooth. 

This artificial tooth root will be surgically placed in your jawbone so a tooth replacement such as a crown or bridge can be attached. Once the procedure is complete, your implant will look and feel similar to your natural teeth. 

Nevertheless, if your jawbone is too soft or thin to support a dental implant, you may require a bone grafting procedure to preserve your oral health and strengthen your jawbone. A bone graft may also be required to regenerate bone loss caused by severe periodontal disease in order to prevent teeth from becoming loose or falling out.

The Dental Implant Procedure

Typically, dentists perform the dental implant procedure in stages, beginning with tooth extraction before preparing the jawbone for surgery. If a bone graft is necessary, the dentist will add tissue to your jawbone to strengthen it and restore areas where the bone has deteriorated. A bone graft can also restore the proper facial contour.

For the dental implant, a titanium rod is placed underneath gum tissue into the jawbone, before the gum tissue is stitched back into place. The implant will then begin to bond to the bone through a process called osseointegration. As the area heals, the implant attaches to the gum tissue.

During another appointment, the dentist will attach the abutment to the rod, before using a tooth replacement to cap the abutment, leaving you with a functional, natural-looking tooth.

Bone Grafting

Bone graft material can be obtained from the patient's own body (autogenous), a human tissue bank (allograft), or an animal tissue bank (xenograft) (xenograft). On occasion, synthetic material is employed (alloplast). The tissue is then implanted into the jawbone.

It may take several months after a bone grafting procedure for the transplanted bone to generate enough new bone to support the placement of a dental implant. 

Once the jawbone has healed, your dentist can surgically place the implant into the jawbone. This stage may also take up to several months to heal. 

The next step is to place the abutment (an extension of the implant's metal post) into the jaw. After another period to allow the soft tissue to heal, the dentist will take moulds or impressions of the teeth and jawbone before inserting the tooth replacement. 

A Healthier Smile

While bone grafting and dental implant procedures can be time-consuming, they can result in healthier teeth and protect your oral and overall health from the effects of bone deterioration and tooth loss.
