<unk>  or alveolar ridge<unk>  is a procedure to reduce bone loss after tooth extraction. After tooth extraction, the jaw bone has a natural tendency to become narrow, and lose its original shape because the bone quickly resorbs, resulting in 30–60% loss in bone volume in the first six months. Bone loss, can compromise the ability to place a dental implant (to replace the tooth), or its aesthetics and functional ability.<unk>  attempts to prevent bone loss by bone grafting the<unk>  immediately after extraction. With the procedure, the gum is retracted, the tooth is removed, material (usually a bone substitute) is placed in the tooth<unk> , it is covered with a barrier membrane, and sutured closed. Roughly 30 days after<unk> , the barrier membrane is either removed, or it resorbs, and the callous of bone covers with new gingiva. While there is good evidence that<unk>  prevents bone loss, there is no definitive proof that this leads to higher implants success or long-term health.
