BONE GRAFTING AND GUIDED TISSUE REGENERATION
Since periodontal disease is the leading cause of bone loss in the oral cavity, bone grafting is a useful procedure to replace lost bone tissue and to stimulate natural bone growth. Bone grafts may be needed to create a stable foundation for the placement of a dental implant, to arrest the progression of periodontal disease, or to create a more esthetic smile. Bone graft materials can come from the person receiving the graft (Autogenous bone graft), from synthetic bone made in a laboratory (Allograft), or from another animal (Xenograft). Freeze dried demineralized bone (FDDMB), which has been irradiated to completely sterilize it, can also be used as a graft material. Biologic modifiers that aid in regeneration such as bone morphogenic protein, enamel matrix protein, and platelet derived growth factor are also available. All of these grafting materials are safe and have been used with success for many years. After your gum tissue has been lifted back and the disease causing bacteria has been removed from the teeth and roots, bone grafting material is used to fill the voids in the bone surrounding the teeth. Often the bone graft is also combined with tissue-stimulating proteins which help the body to regenerate bone and tissue. Tissue regenerative membranes may also be placed over the bone graft to stabilize the graft and further stimulate bone and tissue regeneration. Removing bacteria and toxins and regenerating bone and tissue helps to reduce pocket depths and repair damage caused by periodontal disease.
