The following case definitions and characteristics of peri‐implant health, peri‐implant mucositis, and peri‐implantitis should be viewed within context of several potential confounding factors.

It is known that there is no generic implant and that there are numerous implant designs with different surface characteristics, surgical and loading protocols. The degree of physiological remodeling after implant placement may vary and will determine the crestal level of bone expected in peri‐implant health. The amount of remodeling will also be influenced by a number of local and systemic factors. Clinicians should be aware that extensive peri‐implant bone loss may also be reflective of the development of peri‐implantitis during the remodeling phase.

It is recommended that the clinician obtain baseline radiographic and probing measurements following the completion of the implant‐supported prosthesis. An additional radiograph after a loading period should be taken to establish a bone level reference following physiological remodeling. If the patient presents for the first time with an implant‐supported prosthesis the clinician should try to obtain clinical records and previous radiographs in order to assess changes in bone levels.

How do we define a case of peri‐implant health in day‐to‐day clinical practice and teaching situations?

It should be noted that probing depths depend on the height of the soft tissue at the location of the implant. Furthermore, peri‐implant tissue health can exist around implants with variable levels of bone support.

How do we define a case of peri‐implant mucositis in day‐to‐day clinical practice and teaching situations?

It should be noted that visual signs of inflammation can vary and that peri‐implant mucositis can exist around implants with variable levels of bone support.
