Bone Grafting & Sinus Lift
Over a period of time, the jawbone associated with missing teeth is reabsorbed and is lost. 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 function and appearance.
Bone grafting can repair and replace the missing bone from dental implant sites when bone loss is due to:
- previous extractions
- tooth infections
- gum disease
- or injuries and trauma to the bone
Depending upon the amount and location of the bone loss we use different materials to achieve adequate bone for dental implant placement. These materials include using your own bone (autogenic) harvested from another area, bone from a different species (xenogenic) usually bovine (cow) derived (this bone is processed at very high temperatures to avoid the potential for immune rejection and contamination), or synthetic bone constituents.
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.
Once the dentist has accessed the future implant site they will be able to determine which type of bone graft material and technique is right for you.
The sinuses are located behind your cheeks and on top of the upper teeth. Some of the roots of the natural upper teeth extend up into the sinuses. When these upper teeth are removed, there is often just a thin wall of bone separating the 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.
Luckily there is a solution and it’s called a sinus 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 bone is inserted into the floor of the sinus. After several months of healing, the bone becomes part of the patient’s jaw and dental implants can be inserted into this new sinus bone.
If there's enough bone between the upper jaw and the bottom of the sinus to stabilize the implant well, sinus augmentations and implant placement can sometimes be performed as a single procedure. If there's not enough bone available, the sinus augmentation will have to be performed first. After several months, when the graft is integrated into bone, the dental implant can be placed.
Platelet- Rich Plasma (PRP)
Platelet rich plasma (PRP) is exactly what the name suggests. The substance is a one of the by-products of blood (plasma) that is rich in platelets. Until now, its use has been confined to the hospital setting. This was due mainly to the cost of separating the platelets from the blood and the large amount of blood needed to produce a suitable quantity of platelets. New technology permits us to harvest and produce a sufficient quantity of platelets from only a small blood drawn from the patient in our clinic.
Platelet Rich Plasma permits the body to take advantage of the normal healing pathways at a greatly accelerated rate. During the healing process, the body rushes many cells and cell-types to the wound in order to initiate the healing process. One of those cell types is platelets. Platelets perform many functions, including formation of a blood clot and release of growth factors into the wound. These growth factors (platelet derived growth factors, transforming growth factor beta, and insulin-like growth factor) function to assist the body in repairing itself by stimulating stem cells to regenerate new tissue. The more concentrated growth factors released into the wound, the more stem cells stimulated to produce new tissue. Thus, one can easily see that Platelet Rich Plasma permits the body to heal faster and more efficiently.
A subfamily of transforming growth factor beta, is bone morphogenic protein. This protein has been shown to induce the formation of new bone in research studies in animals and humans. By adding Platelet Rich Plasma, and thus bone morphogenic protein, to the implant site with bone substitute particles, we can now grow bone more predictably and faster than ever before.
The process works by taking a small amount of your blood and placing it in a centrifuge to separate the platelet rich plasma from the red blood cells. They are then mixed with the grafting material and added to grafting site. This greatly reduces the time between receiving your dental implant and placement of the crown or bridge.
Why Boutique Dental Bondi?
We understand that undergoing bone grafting and sinus lifting can sound daunting, which is we make every effort to keep you at ease and to give your grafting procedure the greatest chance of success. Some of our differences include:
Individualised and planned approach- everyone's bone heals and integrates with the graft at a different rate, which is why we use our 3D CBCT to produce a high definition view of your bone prior to the graft and prior to any implant placement to ensure that the graft placement is accurately planned beforehand and is ready for the ideal dental implant placement.
More than just clean- All of the equipment used during the procedure is 100% sterile and tracked. Any materials that cannot be sterilised are disposed of immediately at the end of your treatment. Our centrifuge also has a UV steriliser to prevent any unlikely contamination of the blood whilst it is in the centrifuge.
Your Safety- All of the bone grafting materials that we use are 100% TGA approved. They are Swiss-made and are all completely safe and are of the highest quality.
Convenience- Since Platelet-Rich Plasma harvesting is done with only a small amount of blood in our clinic, you don't need to incur the added expense and inconvenience of having the harvesting procedure done in the hospital or at the blood bank.
