Sinus Lift & Bone Grafting

What if I dont have bones? No worries

Sinus Lift & Bone Grafting

Bone grafting and sinus lifts are commonly used techniques for preparing a site for dental implants, as implants require sufficient bone height in order to be fully integrated for maximum support. For certain procedures such as dental implants and dental bridges, it can be necessary to augment the jawbone.

Over a period of time, the jawbone associated with missing teeth atrophies or is reabsorbed. This often leaves a condition in which there are poor quality and quantity of bone suitable for placement of dental implants.

Today, we have the ability to grow bone where needed. This not only gives us the opportunity to place implants of proper length and width, but it also gives us a chance to restore functionality and aesthetic appearance.

Bone Grafting

A bone graft consists of human, bovine or synthetic bone tissue that is placed on the bone needing augmentation. Dentist uses the demineralized freeze-dried bone for grafting procedures. It is the most widely used grafting material in periodontics.

The bone graft builds up the existing jaw bone as well as stimulating the growth of new bone, making it possible for the patient to receive a dental implant.

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 bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special membranes may be utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. This is called guided bone regeneration or guided tissue regeneration.

Sinus Lift

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.

The maxillary sinuses are located just above the upper posterior teeth. If the thickness of bone from the ridge of the upper jaw to the floor of the sinus is insufficient, dental implant posts can poke through into the sinus cavity. To remedy this risk, Dentist performs a surgical procedure called a sinus lift (sometimes called sinus augmentation or sinus elevation).

The need for a sinus lift usually occurs because one or more of the back teeth are missing, causing bone loss over time. Bone loss can also sometimes happen as a result of periodontal disease as well.
