With the growing awareness of the implant concept, the clinical application of dental implants has made a great success. Dental implants take long-term physiological function in the oral complex environment, not only relying on stable osseointegration which can withstand long-term occlusal load between the implant and bone but also the close attachment in soft tissue around the implant neck which plays a role of crucial barrier.

The attachment of soft tissue around the implant neck has attracted widespread attention. The attachment of soft tissue around the implant neck and the influencing factors were reviewed.
