Over a period of time, the jaw bone associated with missing teeth atrophies or is reabsorbed. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates 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, it also gives us a chance to restore functionality and aesthetic appearance.
Major Bone Grafting
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.
Major bone grafts are typically performed to repair defects of the jaws. These defects may arise as a result of traumatic injuries, tumor surgery, or congenital defects. Large defects are repaired using the patient’s own bone. This bone is harvested from a number of different sites depending on the size of the defect. The skull (cranium), 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.
PRF THERAPY (platelet rich fibrin)
FOR REGENERATING ORAL TISSUES AND IMPROVED HEALING
L-PRF™ is basically a bioactive “band-aid” that is created from your own blood and then placed in your surgery sites to promote healing. A sample of your blood is collected in a tube, just as it would be for a blood test. Your doctor then uses the unique IntraSpin™ System to separate and concentrate certain important cells and active proteins by spinning your own blood in a dedicated centrifuge. After a fast preparation the bioactive concentrate, created just from your own blood, is now ideal for your procedure.
L-PRF™ is currently being used in our office for bone grafting, extraction socket bone preservation, sinus lifting, and some gum grafting procedures.
When placed in surgery sites, L-PRF releases your body’s own natural healing proteins, creating a more efficient network for cells to enhance the healing process. Depending on your situation, we may elect to supplement your periodontal surgical treatment with L-PRF membranes or plugs.
L-PRF™is a 3-dimensional combination of Platelet Rich Fibrin derived from the patient’s blood. A simplified chairside procedure results in the production of a thin, compressed layer of platelet rich fibrin membrane or plugs that are strong, pliable and suitable for suturing. This natural fibrin network is rich in platelets, growth factors and cytokines (cellular messaging molecules) that are derived from the blood platelets and leukocytes.
Clinically, Leukocyte-Platelet Rich Fibrin displays excellent working properties. This biomaterial from you is resilient, strong and pliable, making it easy to manipulate. It can be cut to size, and is supple enough for adapting to many anatomical areas. It is adhesive in nature and very receptive to suturing. In addition, there is ample working time since L-PRF™ is stable at room temperature for several hours.
