Gum recession wants to repair the soft tissue, there are two types of restorations with different rates. The first one is to perform a periodontal GBR procedure, which requires the flap of our gums, then the implantation of bone powder, then the placement of the osteochondral membrane, and finally the suturing of the gums. With a later review, a certain height of the alveolar bone can be restored and the gum recession can be improved at the same time. The cost is charged according to the amount of bone powder implanted. 6,000 yuan of bone powder is usually about 5 grams, and if more bone powder is implanted, it will take tens to tens of thousands of yuan. The second type is suitable for patients with mild gum atrophy, and can take periodontal tunnel technology, by taking part of the soft tissue of the upper palate to fill the part of our missing gums, and cushion it up, which can restore a certain aesthetic effect, and the general charge is between 1000-3000 yuan.
