Diagnosis of peri‐implant status after peri‐implantitis treatment: Proposal of a new classification

Abstract

Background

The 2017 World Workshop classified peri‐implant diseases into health, peri‐implant mucositis, and peri‐implantitis. The aim of this article is to build upon this recent classification and propose a framework for the diagnosis of peri‐implant status after resective or regenerative surgical treatment for peri‐implantitis.

Methods

A literature review was conducted to discuss the relevant diagnostic clinical and radiographic parameters, including probing depth (PD), bleeding on probing (BOP), visual inspection, and radiographic bone loss. Case definitions of possible treatment outcomes were discussed, and a flowchart was constructed to guide post‐treatment diagnosis according to all the possible clinical scenarios which can be encountered in daily practice.

Results

Three possible treatment outcomes were identified after resective treatment of peri‐implantitis: 1) healthy implant with a reduced support, 2) peri‐implant mucositis with a reduced support, and 3) recurrent/refractory peri‐implantitis. After regenerative treatment for peri‐implantitis, the peri‐implant condition was classified according to the same diagnoses with the addition of healthy implant or peri‐implant mucositis after complete regeneration for cases where complete regeneration was attained. Criteria for successful treatment of peri‐implantitis were proposed. After resective therapy, a successful treatment outcome was defined as healthy implant with a reduced support, whereas, after regenerative therapy, a successful outcome was described as either peri‐implant health after complete regeneration or healthy implant with a reduced support.

Conclusions

The proposed classification system of peri‐implant status after treatment for peri‐implantitis provides a framework for diagnosing the various forms of peri‐implant stability or disease in order to guide clinical decision‐making post‐treatment.
