Bone Grafting in Lafayette, LA

Bone loss in the jawbone is common when one or more teeth have been lost due to injury, decay, or trauma.  Without the tooth in place to stimulate the jawbone, the bone around the missing tooth will begin to deteriorate.  Over time, the jawbone may deteriorate to such an extent that there may not be enough bone to place dental implants.  In cases such as these, your dentist may recommend having a bone grafting procedure. 

Bone grafting is the replacement or augmentation of missing bone around the teeth. 

There are three types of bone graft procedures: autogenous, allograft, and xenograft. 

Autogenous grafts take bone from one area of the patient’s body and transplant it to the location in the mouth being restored.  The bone is usually taken from non-essential bones such as the chin area.  The benefit of an autogenous bone graft is that the bone used comes solely from the patient thus reducing the likelihood of rejection and infection.  The bone is also still “live”, meaning it still has active cellular material.

Allografts also use human bone transplanted to the area in the mouth being restored.  However, allografts do not use the patient’s own bone.  Instead, the bone usually comes from cadavers who have donated their bone to bone-banks.  All allograft bone material is carefully screened and is considered very safe.  Xenografts also replace bone in the area requiring treatment, however the bone comes from a non-human source.  Usually the non-human source is bovine (cow).   Allografts and Xenografts are used because they do not require a second surgical site to harvest bone and ample amounts of bone can be easily attained.

The Procedure

There are multiple types of bone grafting procedures. Your doctor will help determine which type of bone grafting procedure you will need. In all bone grafting procedures, you will first be numbed or sedated so that you are comfortable during the procedure.


Block Grafting

A local anesthetic is first used to numb the area where the bone will be removed as well as the location where the bone will be augmented.  An incision is made in the gums around where the bone will be augmented.  This is done so that the dentist can see exactly how much bone will be need before harvesting it from the patient (if an autogenous graft is being performed).

Next, the dentist will make a cut in the gums below the lower front teeth in order to expose the chin bone.  The dentist will then remove a part of the bone along with any bone marrow. This incision is then closed with stitches. 

The bone removed from the chin will then be anchored in place in the jawbone with small titanium screws. 

The dentist may place a mixture of your bone marrow and some bone-grafting material around the bone graft to help speed healing. The incision is then closed with stitches.


Sinus Grafting


Before the procedure begins, a local anesthetic is applied to the site.  The doctor will then create a small opening in the bone to access the sinus cavity.  Using a small instrument, the doctor will then gently lift the sinus back to its original position.  A grafting material is then placed beneath the newly raised sinus cavity along the existing bone.  This grafting material will then mesh with your bone, thus creating more bone.


Guided Bone Regeneration

During guided bone regeneration (GBR) procedures, the gum is lifted in the affected area, exposing the deficient bone in the jaw. Regenerative membranes are then placed between the gums and the bone. This membrane is designed to encourage natural bone tissue to grow and heal by blocking fast-growing gum tissue from filling in the area where the bone is lost. Once the membrane is placed, the area is sutured closed.

After the Procedure

After the procedure you will likely be given antibiotics as well as pain medication. You’ll be asked to follow a restricted diet of soft foods such as pastas and Jell-O. Bone grafts usually take three to six months, and sometimes as much as nine months, to heal completely. Dental implants will not be placed until your mouth has healed completely.
