Bone Grafting For Implants

Why Bone Grafting?

Today, bone grafting procedures have become almost an integral part of implant reconstruction at our office in Dallas. In many instances, a potential implant site in the upper or lower jaw does not offer enough bone volume or quantity to accommodate a root form implant of proper size or in the proper place. This is usually a result of bone resorption (shrinkage) that has taken place since the loss of the tooth. Bone grafting procedures are utilizes to re-establish bone dimension. We now have the ability to grow bone where it is needed. This not only gives us the opportunity to place implants of proper length and width, it also gives us a chance to restore function and a pleasing esthetic appearance. The bone graft procedures are divided into two classes: ridge bone augmentation and sinus augmentation.

Bone augmentation is a grafting procedure used to repair implant sites with inadequate bone structure due to previous extractions, gum disease or injuries. The bone is obtained from the patient’s mouth or artificial bone substitutes. Special membranes are utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. These special membranes help guide bone regeneration. Grafting is performed in the office either in conjunction with the implant placement or as separate procedure. Dr. Orth will discuss these options with you.

In extremely rare cases major bone grafts are necessary to repair larger defects of the jaws. These defects may arise as a result of severe traumatic injuries (auto accidents etc.), tumor surgery, or congenital defects. Large defects are repaired using the patient’s own bone. The bone is harvested from different parts of the body outside of the mouth. The hip (iliac crest), and lateral knee (tibia), are common donor sites. These procedures are routinely performed in an operating room and require a hospital stay.

Dr. Orth will refer you to an oral surgeon if these procedure are necessary.

Sinus Augmentation

The maxillary sinuses are behind your cheeks and on top of the upper teeth. Sinuses are like empty rooms that have nothing in them. Some of the roots of the natural upper teeth extend up into the maxillary sinuses. When these upper teeth are removed, there is often just a thin wall of bone separating the maxillary sinus and the mouth. Dental implants need bone to hold them in place. When the sinus wall is very thin, it is impossible to place dental implants in this bone.

There is a solution and it’s called a sinus augmentation graft or sinus lift graft. The dental implant surgeon enters the sinus from where the upper teeth used to be. The sinus membrane is then lifted upward and donor bone is inserted into the floor of the sinus. Keep in mind that the floor of the sinus is the roof of the upper jaw. After several months of healing, the bone becomes part of the patient’s jaw and dental implants can be inserted and stabilized in this new sinus bone.

The sinus graft makes it possible for many patients to have dental implants when years ago there was no other option other than wearing loose dentures.

If enough bone between the upper jaw ridge and the bottom of the sinus is available to stabilize the implant well, sinus augmentations and implant placement can sometimes be performed as a single procedure. If not enough bone is available, the sinus augmentation will have to be performed first, then the graft will have to mature for several months, depending upon the type of graft material used. Once the graft has matured, the implants can be placed.
