Bone loss in the jaw bone is common when one or more teeth have been lost due to injury, decay, or trauma. Without the tooth in place to stimulate the jaw bone, the bone around the missing tooth will begin to deteriorate. Over time, the jaw bone may deteriorate to such an extent that facial aesthetics change and there may not be enough bone to place dental implants. In cases such as these, Dr. Danielle Wehle may recommend a bone grafting procedure in Santa Clara, CA. Bone grafting is the replacement or augmentation of missing bone around the teeth and in areas where teeth have been lost. It is often recommended prior to certain treatments, such as a dental implant procedure.
Depending on how much bone is lost and where the bone loss has occurred, the particular treatment may vary. We offer a variety of bone grafting options depending on your unique situation.
Bone grafting is the replacement or augmentation of missing bone around the teeth and in areas where teeth have been lost. There are three choices for bone grafting materials, autogenous grafts take bone from one area of the patient’s body and transplant it to the location in the mouth being restored. Allografts use donated human bone transplanted to the area in the mouth being restored. Xenografts usually take bone from a non-human source such as a cow. During the procedure Dr. Wehle will place the bone grafting materials in areas where natural jaw bone has resorbed. By regenerating new bone from the graft, proper density and strength is rebuilt to accommodate one or more implants, along with restoring the natural contours of the face.
Ridge, or socket, preservation procedures are ideally performed immediately following a tooth extraction, as it helps to promote the esthetics of the ridge and avoid bony defects. Dr. Wehle will perform the extraction carefully so as to not disturb existing bone in the socket. Next, she will place a specialized bone grafting product either from another area of your body of a safe donor source. The bone grafting material is designed to replace bone and stimulate bone growth in the socket. After it has been placed, the grafting material will be stabilized with sutures and possibly a collagen membrane. Healing time is approximately three to five months before a dental implant can be placed.
Guided tissue bone regeneration helps the body to regenerate lost bone and does not always require the removal of bone from any other part of the body. Instead, we may use membrane barriers, tissue stimulating proteins, or bioactive growth factor gels to encouraging the ligament fibers and bone to grow.
Patients who have lost teeth in the upper premolar or molar areas of the jaw often require a sinus lift, or sinus augmentation, in order to have dental implants placed. There are two forms of sinus lift procedures. In one type, our doctor will create a small opening in the bone to access the sinus cavity. Using a small instrument, she will gently lift the sinus into a more favorable position. This procedure helps to encourage natural bone growth to fill the space created, but a bone grafting material is often placed beneath the newly raised sinus cavity along the existing bone. This grafting material will then mesh with your existing bone, thus creating more bone. The second type involves gaining access to the sinus cavity through an opening created in the bone. Bone is grafted to the floor of the sinus to increase the bone height. The sinus is not actually lifted in this case, but rather filled in a bit to increase the bone to a sufficient thickness that can support an implant.
Often, after a tooth is removed, the bone in the jaw will begin to deteriorate and recede. The height and width of the socket, which was supported by the tooth, will begin to shrink after the tooth is removed.
