Need A Dental Implant but Not Enough Bone?

  • Bone grafting is often closely associated with dental restorations such as bridge work and dental implants.
  • In the majority of cases, the success of a restoration procedure can hinge on the height, depth, and width of the jawbone at the implant site.
  • When the jawbone associated with missing teeth shrinks, or has sustained significant damage, the implant(s) cannot be supported on this unstable foundation and bone grafting is usually recommended.

Causes for Jaw Bone Volume Shrinkage

  • Periodontal Disease Periodontal disease can affect and permanently damage the jaw bone that supports the teeth. Affected areas progressively worsen until the teeth become unstable.
  • Tooth Extraction Studies have shown that patients who have experienced a tooth extraction subsequently lose 40-60% of the bone surrounding the extraction site during the following three years. Loss of bone results in what is called a “bone defect”.
  • Injuries and Infections Dental injuries and other physical injuries resulting from a blow to the jaw can cause the bone to recede. Infections can also cause the jaw bone to recede in a similar way.

Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease or injuries. The bone is either obtained from a tissue bank or your own bone is taken from the jaw, hip or tibia (below the knee.)

Sinus Lift (Graft)

Sinus Lift is a surgical method by which we can increase the amount of bone tissue of the upper jaw, above the molars and premolars, and are also performed to replace bone in the posterior upper jaw.

The maxillary sinuses are behind your cheeks and on top of the upper teeth and 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.

To address this problem our dentist enters the sinus from where the upper teeth used to be. The sinus membrane is then lifted upward and donor’s bone is inserted into the floor of the sinus. After healing, the bone becomes part of the patient’s jaw and dental implants can be inserted and stabilized in this new sinus bone.

A dentist can perform a single procedure for sinus augmentations and implant placement when there is enough bone between the upper jaw ridge and the bottom of the sinus is available to stabilize the implant well. 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. The dentist then places an implant once the graft is mature.

The Benefits

Getting dental implants is a wonderful solution for many individuals. Implants are placed in your facial bone, and they remain there permanently. The implants, which are tiny titanium screws, serve as prosthetic roots. Crowns are placed over the implants, so you also have prosthetic teeth.

Unfortunately, not everyone has enough bone to support the placement of implants. This usually indicates bone loss due to advanced gum disease, or periodontitis. If you do not have enough bone to support implants, don’t worry. Your local Oviedo prosthodontist can provide a solution to this common problem.

The solution is to implement a bone grafting/sinus lift procedure. Bone is grafted from the sinus area to produce the necessary bone. Ultimately, the bone becomes your natural bone in the affected area. Then, implants can be successfully screwed into the new bone tissue.

Talk to your dentist about the possibility of getting dental implants. Even if you have much bone loss, getting implants is still possible. Dr. Amit Kamat is a board-certified prosthodontist, and he is highly qualified. He will help you determine how to proceed with getting dental implants.

Why Bone Loss Affects the Implant Process

A dental implant restoration procedure relies on the bone as an anchor. The depth, width, and height of that bone affect the treatment’s outcome. The bone near the missing teeth can shrink or become damaged. The problem is that the unstable bone as a foundation does not support the implant.

How Bone Loss Occurs

Losing bone tissue in your jaw is not abnormal with periodontal disease. If you have already lost teeth, you probably have lost bone elsewhere. Gum disease can cause damage to the bone that supports the teeth. This condition gets worse over time until the teeth ultimately become loose.

You may experience a bone loss if you choose to remove a tooth. You could lose up to 60 percent of the surrounding bone tissue. This issue might progress for approximately three years after the tooth extraction. This kind of bone loss is what dentist refer to as a bone defect.

Other factors can also cause your bone tissue to shrink or recede. You can lose bone due to an infection or an injury. A blow to the jaw could result in bone loss. An infection can lead to bone loss in your jaw, too. Bone grafting and a sinus lift could help to restore your smile.

How a Dentist Can Help

Bone grafting is a solution to an implant site with insufficient bone. A bone graft can be done from a few different areas of your body. The dentist can take bone from your hip or below the knee. Bone can also be extracted from a different part of your jaw.

A bone graft can replace the lost bone in your upper jaw. This is done via a sinus bone graft. The new bone replaces missing bone in the posterior upper jaw region.

The bone between your mouth and your maxillary sinus may diminish. Then, you will require a sinus lift to counteract the lost tissue. The dentist goes into the sinus and lifts the sinus membrane. The dentist then places the new bone in the sinus floor.

Talk to Dr. Amit Kamat about bone grafting and sinus lift. If you have bone loss but want implants, Dr. Kamat can help. By grafting donor bone onto your existing tissue, he creates new tissue. That tissue will be the anchor for your prosthetic teeth.

You do not need to suffer from diminishing bone and missing teeth. Dental implants are a popular treatment in Oviedo, FL.
