Abstract:
Sufficient keratinized mucosa is important for ensuring the long-term stability and aesthetics of dental implants.How to ef-fectively augment the soft tissue volume at sites with insufficient keratinized mucosa width(KMW)has gradually become a hot research topic for current scholars.Apically positioned flap(APF)with free gingival graft(FGG)is recognized as the approach of choice for peri-implant keratinized mucosal augmentation,but the postoperative shrinkage and its influencing factors are not completely clear.The objective of this review is to explain the significance of keratinized mucosa to peri-implant tissue health,analyze the relevant factors af-fecting postoperative contraction of free gingival grafts,and finally propose a risk factor assessment table for postoperative shrinkage of FGG,with the aim of providing clinicians with a scientific and effective strategy for peri-implant soft tissue management.
