After a dental extraction, the bone surrounding the now missing tooth will slowly begin to resorb (i.e., shrink), resulting in a loss of both bone height and width. As bone resorbs the overlying gum tissue also tends to lose both volume and its normal anatomic form. This loss of bone and gum tissue following tooth extraction often results in both functional and cosmetic defects, leaving an unsightly collapsed appearance.
At Peak Oral and Maxillofacial Surgery & Implant Center, we take a proactive stance on bone preservation. Bone and gum tissue loss following tooth removal can either be greatly reduced or completely eliminated thanks to advances in grafting procedures and bioengineering. Following the removal of a tooth, a specially bioengineered graft material is placed within the extraction socket. The bone graft material not only supports new bone growth, but also has been shown to preserve bone and overlying soft tissue following tooth removal.
For those patients that have had teeth missing for some time with typical resultant bone loss, Dr. Noori employs several bone grafting techniques to restore deficient areas, thereby creating implant placement possibilities that would otherwise be absent.
One of the areas of the mouth where such bone grafting is most commonly needed and performed is the maxillary sinus cavity. This is usually a concern when placing implants into the posterior aspect of the upper jaw, an area that naturally has much softer bone than the rest of the upper jaw or lower jaw. More importantly, if there has been a lot of bone loss in this area of the jaw than placing an implant into the jaw bone may lead to a significant portion of the implant protruding into the sinus cavity in addition to potentially loosening and failing all together.
In these specific situations of bone deficiency in the posterior portion of the maxilla, Dr. Noori will first perform a sinus lift. This will help increase the height of bone in the Maxilla by either packing in bone directly from the extraction site where the tooth used to be or through a small, thumbnail size hole that is made in the side of the upper jaw. Sometimes this process can be done at the same time as the placement of the dental implant; at other times, it will then need to be followed by a healing phase of several months to allow the grafted bone to solidify prior to proceeding with implant placement.
