One of the major factors that directly affects dental implant success is the quality and quantity of bone that is available. As soon as a tooth is lost, either from gum disease or from a surgical procedure, the supporting bone starts to recede and shrink. The loss of a tooth affects the major structures of the face, making a replacement an urgent matter. Dental implants are one such option, which are anchored in the bone after being surgically placed. If there is a small amount of bone, or if the bone present is fragile and weak (poor quality), placing implants firmly will be problematic. Luckily, modern oral medicine offers many innovative procedures that enable growing new bone in your jaw. Bone grafting, the most common solution, takes bone from one area in your mouth and moves it to another, creating a fresh base for implants. With this strong, abundant bone restored, placing a long-lasting implant is a relatively easy and predictable treatment for our skilled Glen Ellyn, IL dentists, Drs. Thomas and Jessica Gibbs.
It is important to replace missing teeth as soon as they are lost. This will retain as much of the original, healthy bone as possible in the areas where there are no teeth. The innovations in dental implant design, combined with improvements in bone grafting materials and surgical techniques, has made the placement of dental implants possible in areas which, half a generation ago, would have been totally off-limits to any practical repair. To accurately assess the amount of bone available, the most advanced technology currently used by our office is the CT cone beam scan that provides an extremely useful, highly detailed assessment of the bone quality and shape. For bone grafting procedures, we use autogenous bone (the bone of the individual patient themselves) whenever possible to ensure the successful integration of new and existing bone. Bone grafting prevents additional bone loss and helps people chew and speak more comfortably with restorative dental implants.
A block of bone is removed from another area of the body and screwed into the position where the dental implant will ultimately be placed. The bone graft must remain in place for 2 to 6 months before the implant is inserted.
The sinus membrane is lifted upward to facilitate insertion of donor bone into the floor of the sinus cavity. This is usually done in the area of the upper back molars, when either the sinus has expanded on its own to the area where the lost tooth once was, or the bone has withered away in height and width, or both.
When teeth fall out or are removed, bone in the remaining socket often degenerates between 40 and 60 percent, both in terms of width and height, within the first year! Socket preservation grafting reduces such bone loss by adding bone grafting material to the space after tooth loss or extraction.
Multiple teeth lost or extracted in a row can cause a whole ridge section to resorb and shrink. Ridge augmentation grafts replace the height, width, and natural contours of the jawline to create a strong foundation for dental implants.
Gum tissues grow quickly. To prevent gum tissues from growing over bone grafts, a membrane barrier is often used to cover surgical spaces. This membrane blocks gum tissues from growing into these areas.
Plasma rich growth factors (PRGF) are derived from the patient’s own blood and are placed at the bone grafting site PRGF jumpstarts the healing process by stimulating the regeneration of new bone and tissue growth.
