Major & Minor Bone Grafting
Over time, a patient who is missing one or more teeth will experience bone loss as bone tissue from the jaw atrophies or is reabsorbed. This can result in a jaw that’s too weak to support dental implants. But with a special bone grafting procedure, our team can revitalize a patient’s poor bone structure. This not only gives Dr. Rynar the opportunity to place implants, it also allows him to restore functionality and appearance.
The bone in a bone grafting procedure is obtained from either a tissue bank or from the patient’s own jaw, hip, or tibia. Sinus bone grafts can also be performed to replace bone in the posterior upper jaw. What’s more, we may insert dissolvable membranes under the gums to protect the bone graft and encourage regeneration. This is called guided bone regeneration or guided tissue regeneration.
Your maxillary sinuses are located behind your cheeks and on top of your upper teeth. Some of the roots from these upper teeth extend into the sinuses, which are otherwise like empty rooms. When any of these teeth are removed, there is often just a thin wall of bone separating the maxillary sinus from the mouth. Because dental implants need a strong foundation, it’s impossible to place them when this sinus wall is too thin.
If enough bone between the upper jaw ridge and the bottom of the sinus is available, sinus augmentation and implant placement can be completed in a single procedure. But if not enough bone is available, we’ll have to perform the sinus augmentation first, and then give it time to mature. Once the graft has matured, the implant(s) can be placed.
If a patient’s ridge becomes reabsorbed, a special procedure known as a ridge expansion may be necessary to increase ridge height and/or width. In this procedure, the bony ridge of the jaw is literally expanded by mechanical means. Bone grafting material can be placed and matured for a few months before the patient’s new implant is placed.
