Abstract: Insufficient width of peri-implant keratinized tissue is a common problem of implant restoration. Previous studies have shown that sufficient keratinized tissue width is not only conducive to the control of plaque, but also can improve the long-term stability of implants. At present, the main approaches for increasing the width of keratinized tissue in clinical practice are: apically repositioned flap, autologous tissue transplantation, allogeneic tissue transplantation, etc. This review summarized the significance of peri-implant keratinized tissue width and the research progress on various methods of keratinized tissue, providing reference for clinical diagnosis and treatment.

Key words: implant, the width of keratinized tissue, apically repositioned flap, autologous tissue transplantation, allogeneic tissue transplantation
