Bone Grafts & Dental Implants
If you are missing a tooth for any number of reasons then your dentist may recommend a dental implant to replace the lost tooth and restore your smile.
This artificial tooth root will be surgically placed in your jawbone so a tooth replacement such as a crown or bridge can be attached. This artificial implant will take on the appearance of a natural tooth helping your smile
While implants can be an ideal option for many patients looking to replace missing teeth there can be situations where the jawbone is too soft or thin to support a dental implant, you may need a bone grafting procedure to help strengthen your jawbone and preserve your oral health. A bone graft might also be needed to regenerate bone loss due to severe gum disease to prevent teeth from loosening or falling out.
The Dental Implant Procedure
Dentists typically perform the dental implant procedure in stages, the first of which is extracting the damaged tooth before preparing the jawbone for surgery. If you require a bone graft, 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 proper contour to the facial area.
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 graft material can be taken from your own body (autogenous), purchased from a human tissue bank (allograft) or an animal tissue bank (xenograft). In some cases, synthetic material is used (alloplast). The material is then transplanted to the jawbone.
Transplanted bones may take a few months to generate enough new bone to support the placement of a dental implant, which contributes to making this a lengthy process.
Once the bone graft has fully healed your dentist will be able to perform the implant procedure which will also take a few months to recover from.
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 molds or impressions of the teeth and jawbone before inserting the tooth replacement.
Helping to Maintain a Healthy Smile
Bone grafting can be a long process but it can leave you with healthier teeth and help protect your oral health from future complications like bone deterioration and missing teeth.
