Influence of the level of compliance with preventive maintenance therapy upon the prevalence of peri‐implant diseases

Abstract

Background: A study was made to evaluate peri‐implant conditions in compliers and erratic compliers with peri‐implant maintenance therapy (PIMT), and to assess the role of site‐specific confounders.Methods: Erratic PIMT compliers (EC) were defined as presenting attendance < 2x/year, while regular compliers (RC) attended ≥ 2x/year. Generalized estimating equations (GEE) were employed to perform a multivariable multilevel analysis in which the peri‐implant condition was established as dependent variable.Results: Overall, 86 non‐smoker patients (42 RC and 44 EC) attending the department of periodontology of the Universitat Internacional de Catalunya were recruited consecutively on a cross‐sectional basis. The mean period of loading was 9.5y. An implant placed in an erratic patient has 88% higher probability of presenting peri‐implant diseases versus RC. Furthermore, the probability of diagnosis of peri‐implantitis was significantly higher in EC vs RC (OR 5.26; 95% CI: 1.51 – 18.29) (p = 0.009). Among other factors, history of periodontitis, non‐hygienic prosthesis, period of implant loading and Modified Plaque Index (MPI) at implant level were shown to significantly increase the risk of peri‐implantitis diagnosis. Although not associated with peri‐implantitis diagnosis risk, keratinized mucosa (KM) width and vestibular depth (VD) were significantly associated to plaque accumulation (mPI).Conclusions: Compliance with PIMT was found to be significantly associated with peri‐implant status. In this sense, attending PIMT < 2x/year may not be sufficient to prevent peri‐implantitis. These outcomes should be limited to a non‐smokers population.This article is protected by copyright.

The Role of Salivary Biomarkers in Monitoring Oral Health in Patients with Implants and Periodontitis

“…In order to ensure the long-term success of dental implant rehabilitation, it is essential to maintain a healthy oral environment, including correct oral hygiene, regular dental control visits, and the avoidance of adverse factors such as smoking. Adequate planning, the control of disease conditions, and the observation of good oral hygiene are crucial for success [20,31].…”

“…It is therefore important to address this problem and minimize the factors contributing to oxidative stress in order to ensure long-term implant rehabilitation success [4,10]. Given the variability between patients and the broad range of host response modulating factors, the identification of a unifying pathogenic mechanism could contribute to improve our understanding of the progression of the disorder and develop new therapeutic options [17,18,31].…”

Supportive therapy following peri‐implantitis treatment: A retrospective study on compliance

“…If our data were adjusted to such a case definition, the RC rate would be about 80%. However, in the context of implant therapy, a minimum recall frequency of once every 5-6 months has been suggested to be critical in order to prevent peri-implantitis (Costa et al, 2023;Leone et al, 2023).…”

“…. However, it is interesting to note that a recall frequency of once every 5-6 months in low-risk profile patients was found to be five times more effective in protecting from peri-implantitis than a single maintenance appointment every 12 months (Leone et al, 2023;Monje et al, 2017).…”

Long‐term outcomes and prognostic factors of surgical treatment of peri‐implantitis – A retrospective study

“…While one patient cohort was prospectively collected based on specific inclusion criteria, the other was based on a retrospective selection of patients with an inherent risk of selection bias. Also inherent to the retrospective nature of this study is the obvious lack of standardization in terms of clinical and radiographic evaluations, and the absence of information on frequency/quality of supportive peri-implant care which may have led to confounding bias (Leone et al, 2023).…”
