Related Implant Procedures
A key to implant success is the quantity and quality of the bone where the implant is to be placed. Implants often require related procedures to prepare the site to receive the implant fixture or to enhance the mouth’s ability to heal. The following information has been prepared to help you better understand possible procedures that Dr. Keller has recommended to assure the most desirable outcome. Please feel free to discuss further any questions you may have after reading the following material.
Sinus Lift (Augmentation)
The upper back jaw has traditionally been one of the most difficult areas to successfully place dental implants due to insufficient bone quantity and quality and close proximity to the sinus. Bone is often lost in this area due to periodontal disease, tooth loss, or denture wear and tear, not leaving enough bone in this area to receive an implant fixture. The sinus floor can be lifted and bone graft materials can be placed to regenerate lost bone and tissue. The bone can be allowed to develop for about four to six months before the implant or implants can be placed. Dr. Keller can readily diagnosis those who are candidates for immediate placement of implants.
Careful management of extraction sockets after tooth extraction prevents unsightly bone loss and a better cosmetic outcome of tooth replacement. Research shows that once a tooth is extracted the bone around the socket will shrink upwards to 25% the first six months and up to 45% over a five year period. By the use of socket augmentation (the use of advanced bioactive materials to retain tissue height) we can eliminate this resorption process. Ideally this should be done at the time of tooth extraction. (See ridge augmentation)
These procedures are recommended to correct concavities in the jawbone where natural teeth are missing. Also used in cases where the jawbone has collapsed following tooth extraction and can help even out replacement teeth that seem too long compared to adjacent teeth.
Over a period of time, the jawbone 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.
We now have the ability to grow bone where needed. This gives us the opportunity to place implants of proper length and width, and it also gives us a chance to more effectively restore esthetic appearance and functionality.
Platelet Rich Plasma (PRP Therapy)
Platelet Rich Plasma is exactly what its name suggests. The substance is a by-product of blood (plasma) that is rich in platelets. Until now, its use has been confined to the hospital setting. This was due to mainly to the cost of separating the platelets from the blood (thousands) and the large amount of blood needed (one unit) to produce a suitable quantity of platelets. New technology permits the doctor to harvest and produce a sufficient quantity of platelets from only 25 cc of blood drawn from the patientprior to surgery.
PRP therapy 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 (GF) into the wound. These growth factors function to assist the body in repairing itself by stimulating stem cells to regenerate new tissue. The more growth factors released/sequestered into the wound, the more stem cells stimulated to produce new host tissue. Thus, one can easily see the PRP permits the body to heal faster and more efficiently.
