Prevalence of peri‐implant disease and risk indicators in a Japanese population with at least 3 years in function—A multicentre retrospective study

Abstract

Objectives The aim of this study was to evaluate the prevalence of peri‐implant disease and analyze risk indicators in Japanese subjects with ≥3 years of implant function. Material and methods Five hundred and forty‐three subjects treated with 1,613 implants were evaluated. Information was collected about the patients’ physical and dental history, as well as implant details. Peri‐implant evaluation included probing depth, bleeding on probing (BoP), suppuration (Sup), and keratinized tissue width. Bone loss was calculated from intra‐oral radiographs taken after 1 year and more than 3 years of function. Implants were classified into three groups: healthy, peri‐implant mucositis (BoP without bone loss), and peri‐implantitis (BoP and/or Sup with bone loss >1 mm). These data were analyzed by multivariable multinomial logistic regression. Results The prevalence of peri‐implant mucositis and peri‐implantitis at the subject level was 23.9% and 15.8%, respectively. An association was found between peri‐implant mucositis and plaque control record (PCR) >20% and keratinized tissue width <2 mm. Peri‐implantitis was associated with PCR >20%, smoking, insertion in the maxilla, and keratinized tissue width <2 mm. Conclusions Within the limitations of this study, the prevalence of peri‐implant diseases was elucidated in a Japanese population. Peri‐implant mucositis was associated with poor oral hygiene and less keratinized tissue. Poor oral hygiene, smoking, insertion in the maxilla, and less keratinized tissue were risk indicators for peri‐implantitis.

Prevalence of peri‐implant diseases among an Italian population of patients with metabolic syndrome: A cross‐sectional study

“…On the other hand, Wada et al . reported a significant lower prevalence, with peri‐implant mucositis and peri‐implantitis being diagnosed at subject level in 23.9% and 15.8%, respectively.…”

Association of prosthetic features and peri‐implantitis: A cross‐sectional study

“…Another topic of debate is the role of smoking as a potential risk factor for peri‐implantitis. While several cross‐sectional studies reported a strong association between a current/history of smoking and peri‐implantitis (Degidi et al, ; Wada et al, ), other studies failed to confirm smoking as a relevant potential risk factor for peri‐implantitis (Marrone et al, ). This controversy is also illustrated by the conclusions reached by recent systematic reviews (Casado, Aguiar, Fernandes Pinheiro, Machodo, & Rosa Pinheiro, ; Schwarz, Derks, Monje, & Wang, ; Sgolastra, Petrucci, Severino, Gatto, & Monaco, ).…”

“…Irregular maintenance visits, poor oral hygiene and a history of periodontitis were found to increase the risk of peri‐implantitis (Derks et al, ; Roccuzzo, Bonino, Aglietta, & Dalmasso, ; Roos‐Jansåker, Lindahl, Renvert, & Renvert, ; Roos‐Jansåker, Renvert, Lindahl, & Renvert, ). Smoking (Degidi, Nardi, & Piattelli, ; Wada et al, ) and systemic diseases, such as diabetes (Daubert, Weinstein, Bordin, Leroux, & Flemmig, ) had been identified to be associated with a higher prevalence of peri‐implantitis. Some studies have reported a relationship between prosthetic factors and peri‐implantitis.…”

Analysis of risk indicators for prevalence of peri-implant diseases in Turkish population

“…Knowledge of the factors that lead to peri-implant disease is crucial for maintaining the dental implants to function properly. Several patient-and implant-related risk indicators including poor oral hygiene, smoking, history of periodontal disease, and compliance of maintenance have been reported [2][3][4]7]. On the other hand, the necessity of keratinized tissue around implant is controversial.…”
