The sufficiency of hard and soft tissue at the implant site is the guarantee of long-term function, health and the appearance of implant denture. Problem of soft tissue recession at the implant site has always been bothering dentists. Traditional methods for augmentation of soft tissue such as gingival transplantation have disadvantages of instability of the increased soft-tissue and more trauma. Lately the methods that base on tissue engineering to increase the soft tissue of peri-implant sites have drawn great attention.
