Socket Grafting to Preserve Bone
The dimensions of your jaw bone are maintained by the presence of your teeth. This "alveolar" bone is generally softer and more vascular than most of your supporting bone such as the femur (leg) or the radius (arm). When a tooth is extracted the alveolar bone which hosed the root literally melts away through a process called resorption. It is a universal process that occurs following all extractions. In severe cases, it will even affect the contours of the face. Notice the pictures below.
The following illustrations show steps that are taken to prevent the collapse of the alveolar bone following extractions.
