The periodontal and the peri-implant pocket potentially share similar microenvironmental conditions (e.g. anaerobic). The initial form of peri-implant infection is peri-implant mucositis, characterised by inflammation of the soft peri-implant mucosa, but with no evidence of destruction of the supporting bone. Progression of inflammation deeper into the implant-supporting bone manifests as peri-implantitis. Peri-implant mucositis and peri-implantitis are considered as the peri-implant variants of gingivitis and periodontitis. Yet, the clinical features of peri-implantitis are much more aggressive, rapidly progressing and difficult to treat, compared to periodontitis. In this sense, the patho-mechanisms of peri-implantitis may be distinct to those of periodontitis, even though they display qualitative similarities [40]. A good description of the relationship between peri-implantitis and periodontitis is that they are ‘fraternal’ infections [41].
Dental Implant Infection: Typical Causes and Control
Published in Huiliang Cao, Silver Nanoparticles for Antibacterial Devices, 2017
Peri-implant mucositis is a reversible inflammation that occurs in the soft tissue around dental implants. Mechanical debridement, supplemented with or without chlorhexidine, resulted in a reduction of plaque and inflammation, and was effective in suppressing or eradicating the pathogenic bacteria that are often associated with peri-implant inflammation (Porras et al. 2002). Since the transmucosal part of implants are designed with a smooth surface, which controls the plaque more easily, mechanical debridement with plastic instruments, which are softer than implant materials and will not jeopardise the smooth surface, is effective and could lead to the reduction in peri-implant mucosal inflammation. Furthermore, a positive effect was documented when antimicrobial mouth rinses were used as an adjunct to the mechanical intervention (Ji et al. 2014; Warreth et al. 2015).

Reason for missing teeth is reported in Table 2. Of the patients, 24 had FDPs with one pontic and six patients had two pontics. One patient was diagnosed with periodontal health, three with gingivitis and 26 with periodontitis. Three of the periodontitis—patients were stable cases of periodontal health (BoP <10% and no site ≥4 mm + BoP). Of the implants evaluated, six presented peri-implant health, 23 peri-implant mucositis and one with peri-implantitis. Measurements of plaque index, BoP and PPDs are provided in Table 3. All 30 FDPs and 26 of the ISCs had occlusal contact. Technical and biological complications recorded at the clinical examination revealed one caries lesion in an FDP abutment tooth, two were endodontically treated through the restoration and four had porcelain fracture. Two ISCs had porcelain fracture and one had a loose occlusal screw.

All patients with periodontitis had stage 3 grade B generalised disease involvement. Patients with peri-implant mucositis were untreated patients. Peri-implantitis and peri-implant mucositis patients were periodontitis patients who had previously generalised periodontitis involvement but had not received any treatment in the last six months. In peri-implantitis patients, the implant with peri-implantitis lesion had never been treated before. Peri-implant mucositis and peri-implantitis patients had two or more implants. Regardless of how many implants were affected in the patient's mouth, the sample was taken from the mucosa around one implant placed only in the maxillary posterior region. Peri-implant mucositis and peri-implantitis patients were partially edentulous patients, and patients who received full-mouth implant rehabilitation were not included. Patients had been using implant-supported fixed prostheses for a period of 2–7 years.
Radiographic peri-implant bone loss after a function time up to 15 years

The definitions of peri-implantitis vary between studies partly due to the different thresholds for peri-implant bone loss. In the present study, the criteria for the diagnosis peri-implant mucositis and peri-implantitis are in accordance with the Consensus report on peri-implant diseases and conditions of the 2017 World Workshop [1]. The prevalence of moderate/severe peri-implantitis was 17% at patient level in the present study compared to 14.5% up to 37% in other studies with at least 5 years of follow-up [5,7,20–22].
