How do we define a case of peri‐implantitis in day‐to‐day clinical practice and teaching situations?
Diagnosis of peri‐implantitis requires:
Presence of bleeding and/or suppuration on gentle probing.
Increased probing depth compared to previous examinations.
Presence of bone loss beyond crestal bone level changes resulting from initial bone remodeling.
In the a...
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 remodeli...
What are the main factors associated with hard‐ and soft‐tissue deficiencies at potential implant sites?
The healing process following tooth loss leads to diminished dimensions of the alveolar process/ridge representing hard‐ and soft‐tissue deficiencies. Larger deficiencies may occur at sites exposed to the following factors: loss of periodontal support, endodontic in...
What is peri‐implantitis?
Peri‐implantitis is a plaque‐associated pathological condition occurring in tissues around dental implants, characterized by inflammation in the peri‐implant mucosa and subsequent progressive loss of supporting bone.
What is the evidence for plaque/biofilm as a principal etiological factor for peri‐implantitis?
There is evidence ...
What are the clinical characteristics of peri‐implant mucositis?
The main clinical characteristic of peri‐implant mucositis is bleeding on gentle probing. Erythema, swelling and/or suppuration may also be present.
Does peri‐implant mucositis exist in the absence of clinical signs of inflammation?
Clinical signs of inflammation are necessary for a diagnosis of peri...
What are the clinical characteristics of a healthy peri‐implant site?
In health, the peri‐implant site is characterized by absence of erythema, bleeding on probing, swelling and suppuration.
What are the main clinical differences between healthy peri‐implant and periodontal tissues?
In health, there are no visual differences between peri‐implant and periodontal t...
The objective of Workgroup 4 was to present a classification on peri‐implant diseases and conditions. Five position papers describing the characteristics of peri‐implant health, peri‐implant mucositis, peri‐implantitis, soft and hard tissue deficiencies and case definitions and diagnostic considerations were prepared prior to the workshop.
In preparing this consensus report regarding...
Consensus report of workgroup 4 of the 2017 World Workshop on the Classification of Periodontal and Peri‐Implant Diseases and Conditions
Abstract
A classification for peri‐implant diseases and conditions was presented. Focused questions on the characteristics of peri‐implant health, peri‐implant mucositis, peri‐implantitis, and soft‐ and hard‐tissue deficiencies were addressed.
