Restoration of the integrity of the dentition with endosseous implants is a treatment option made available to patients not only by specialists but increasingly also by non-specialist dental practitioners. Properly done implants at well-selected sites in suitable persons remain functionally and biologically sound for many years.

Therefore, the implant placement protocol and the restorative protocol should be designed to favour the formation and maintenance of the peri-implant soft tissue unit. The purpose of this short review is to refresh the reader's knowledge of some important factors with regard to establishing and maintaining the integrity of the peri-implant soft tissue.
