Microbiological and functional traits of peri-implant mucositis and correlation with disease severity.

Osseointegrated dental implants replace missing teeth and create an artificial surface for biofilms of complex microbial communities to grow. These biofilms on implants and dental surfaces can trigger infection and inflammation in the surrounding tissue. This study investigated the microbial characteristics of peri-implant mucositis (PM) and explored the correlation between microbial ecological imbalance, community function, and disease severity by comparing the submucosal microflora from PM with those of healthy inter-subject implants and intra-subject gingivitis (G) within a group of 32 individuals. We analyzed submucosal plaques from PM, healthy implant (HI), and G sites using metagenome shotgun sequencing. The bacterial diversity of HIs was higher than that of PM, according to the Simpson index. Beta diversity revealed differences in taxonomic and functional compositions across the groups. Linear discriminant analysis of the effect size identified 15 genera and 37 species as biomarkers that distinguished PM from HIs. Pathways involving cell motility and protein processing in the endoplasmic reticulum were upregulated in PM, while pathways related to the metabolism of cofactors and vitamins were downregulated. Microbial dysbiosis correlated positively with the severity of clinical inflammation measured by the sulcus bleeding index (SBI) in PM. Prevotella and protein processing in the endoplasmic reticulum also correlated positively with the SBI. Our study revealed PM's microbiological and functional traits and suggested the importance of certain functions in disease severity.IMPORTANCEPeri-implant mucositis is an early stage in the progression of peri-implantitis. The high prevalence of it has been a threat to the widespread use of implant prosthodontics. The link between the submucosal microbiome and peri-implant mucositis was demonstrated previously. Nevertheless, the taxonomic and functional composition of the peri-implant mucositis microbiome remains controversial. In this study, we comprehensively characterize the microbial signature of peri-implant mucositis and for the first time, we investigate the correlations between microbial dysbiosis, functional potential, and disease severity. With the help of metagenomic sequencing, we find the positive correlations between microbial dysbiosis, genus Prevotella, pathway of protein processing in the endoplasmic reticulum, and more severe mucosal bleeding in the peri-implant mucositis. Our studies offer insight into the pathogenesis of peri-implant mucositis by providing information on the relationships between community function and disease severity.

Radiographic assessment of the peri-implant site.

While peri-implant mucositis relies solely on clinical parameters, radiological assessment becomes indispensable for diagnosing peri-implantitis. Intraoral radiography, with its simplicity of application, low radiation exposure, and adequate representation of peri-implant structures, stands out as the standard of care for both immediate and follow-up assessments. Standardization by custom-made radiologic splints allows for excellent comparability with previous images and allows for the determination of even small changes in contour and density of the peri-implant bone. Furthermore, other radiographic modalities like panoramic radiography and cone beam computed tomography (CBCT) may provide useful features for specific patients and clinical cases while also showing innate limitations. Beyond the assessment of the marginal peri-implant bone level as the crucial parameter of clinical relevance, radiologic assessment may reveal various other findings related to the prosthetic restoration itself, the precision of its fit to the implant, and the peri-implant soft and hard tissues. Since such findings can be crucial for the assessment of peri-implant health and the implants' prognosis, a systematic diagnostic evaluation pathway for a thorough assessment is recommended to extract all relevant information from radiologic imaging. This article also provides an overview of the clinical and chronological indications for different imaging modalities in peri-implant issues.

Indian Society of Periodontology Good Clinical Practice Recommendations for Peri-implant Care.

Current implant therapy is a frequently employed treatment for individuals who have lost teeth, as it offers functional and biological advantages over old prostheses. Concurrently, active exploration of intervention strategies aims to prevent the progression of peri-implant diseases and manage the existing peri-implant tissue damage. Indian Society of Periodontology has recognized the need for systematic documents to update the everyday clinical practice of general dental practitioners and has provided evidence-based consensus documents, namely good clinical practice recommendations from time to time to raise the oral health-related awareness and standards of oral health-care delivery across the country. The current clinical practice recommendations focused on peri-implant care to bridge the gap between academic theory and clinical practice by compiling evidence-based suggestions for preventing and treating peri-implant diseases. Twenty-eight subject experts across the country prepared these recommendations after a thorough literature review and group discussions. The document has been prepared in three sections covering peri-implant health and maintenance, peri-implant mucositis, and peri-implantitis. It will be a quick and concise reference for oral implant practitioners in patient management. The guidelines provide distinct definitions, signs, and symptoms, treatment required; recall visit specifications for plausible clinical case situations, and home-care recommendations regarding maintaining peri-implant health. The document advocates combined efforts of oral implant practitioners and the population at large with evidence-based, integrated, and comprehensive peri-implant care. By providing accessible, applicable guidance, these guidelines would empower dental professionals to uphold the well-being of implant patients and ensure the long-term success of implant therapy.

The Impact of Peri-Implant Diseases on the General Status of Patients with Cardiovascular Diseases: A Literature Review.

BACKGROUND AND OBJECTIVES: The aim of this study is to connect peri-implantitis to cardiovascular diseases, following the association found between periodontitis and cardiovascular conditions in recent years. MATERIALS AND METHODS: PubMed, Scopus, Web of Science online databases were searched up to June 2023, with the exclusion criteria being research written in a language other than English. The MeSH search items were as follows: ["peri-implant health OR peri-implantitis OR peri-implant mucositis OR peri-implant disease"] AND ["cardiovascular diseases"]. Patient/population (P), intervention (I), comparison (C), outcome (O) framework questions were followed to identify the clinical evidence for the systematic review. Only clinical studies that used a control group to compare the relationship between cardiovascular diseases and peri-implantitis were selected. RESULTS: A total of 118 studies were identified through electronic search of the keywords. After removing duplicates, there were 76 records to be screened. Upon exclusion of ineligible titles and abstracts, 27 studies remained for evaluation. Finally, 23 studies were excluded for not meeting the inclusion criteria, leaving 4 studies to be included in the qualitative analyses. CONCLUSIONS: This study found there is a linear association between mucosal/gingival inflammation and carotid intima-media thickness test (c-IMT) values. Peri-implant mucosal inflammation could be a contributor to the vascular disease burden of an individual; further specific clinical studies should be performed in order to demonstrate this connection.

Microbiota of Peri-Implant Healthy Tissues, Peri-Implant Mucositis, and Peri-Implantitis: A Comprehensive Review.

Understanding the microbiological profiles of peri-implant conditions is crucial for developing effective preventive and therapeutic strategies. This narrative review analyzes the microbial profiles associated with healthy peri-implant sites, peri-implant mucositis, and peri-implantitis, along with related microbiological sampling and analyses. Healthy peri-implant sites are predominantly colonized by Streptococcus, Rothia, Neisseria, and Corynebacterium species, in addition to Gram-positive cocci and facultatively anaerobic rods, forming a stable community that prevents pathogenic colonization and maintains microbial balance. In contrast, peri-implant mucositis shows increased microbial diversity, including both health-associated and pathogenic bacteria such as red and orange complex bacteria, contributing to early tissue inflammation. Peri-implantitis is characterized by even greater microbial diversity and a complex pathogenic biofilm. Predominant pathogens include Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Fusobacterium nucleatum, and unique species like Filifactor alocis and Fretibacterium fastidiosum. Additionally, less common species such as Staphylococcus and Enterobacteriaceae, contributing to disease progression through biofilm formation and increased inflammatory response, along with EBV and human cytomegalovirus with a still not defined role, and Candida albicans contribute to disease progression through biofilm formation, immune modulation, and synergistic inter-kingdom interactions. Future research should standardize diagnostic criteria, employ advanced molecular techniques, integrate microbial data with clinical factors, and highlight inter-kingdom interactions.

Peri-implant phenotype, calprotectin and MMP-8 levels in cases diagnosed with peri-implant disease.

OBJECTIVES: The purpose of this prospective cohort study is to evaluate the effect of peri-implant phenotype (PPh) on the severity of peri-implant diseases and the results of non-surgical mechanical treatment (NSMT), along with calprotectin (CLP) and MMP-8(matrix metalloproteinase-8) levels. MATERIALS AND METHODS: 77 implants from 39 patients were included. The implants were categorized Group-1(peri-implant mucositis), Group-2(peri-implantitis).Baseline (0. Month-PrT) clinical parameters (PD, GI, PI, BOP, CAL) and radiographic bone loss were documented, and peri-implant crevicular fluid (PICF) samples were collected. Various intruments and methodologies were employed to assess PPh components (mucosa thickness, supracrestal tissue height, keratinized mucosa) and peri-implant attached mucosa (AM). NSMT was applied to diseased implant sites. All clinical parameters were reassessed again by taking PICF samples at the 6th month-after treatment (PT). In PICF samples obtained from both groups, MMP-8 and CLP levels were evaluated using the ELISA test. RESULTS: PrT-PD,PrT-GI,PrT-CAL and PrT-BOP percentage values in Group-2 were significantly higher than Group-1.PrT-PD,PrTPI scores are significantly higher in thin biotype implants. All components of the PPh and AM were significantly lower in thin biotype. Intra-group time-dependent changes of MMP-8 and CLP were significant in both groups (p < 0.05). When the relationship between thin and thick biotype and biochemical parameters was evaluated, the change in PrT-PT didn't show a significant difference (p > 0.05). CONCLUSIONS: PPh plays a role in influencing the severity of peri-implant diseases. However, the impact of phenotype on NSMT outcomes was similar in both groups. CLINICAL RELEVANCE: The PPh should be considered when planning implant surgery.

The clinical efficacy of powder air-polishing in the non-surgical treatment of peri-implant diseases: A systematic review and meta-analysis.

Peri-implant diseases, characterized by inflammatory conditions affecting peri-implant tissues, encompass peri-implant mucositis and peri-implantitis. Peri-implant mucositis is an inflammatory lesion limited to the mucosa around an implant, while peri-implantitis extends from the mucosa to the supporting bone, causing a loss of osseointegration. For non-surgical treatments, we tested the null hypothesis that the presence or absence of air-polishing made no difference. The study focused on randomized controlled trials (RCTs) comparing air-polishing with mechanical or ultrasonic debridement, evaluating outcomes such as bleeding on probing (BOP), probing depth (PD), plaque index/plaque score (PI/PS), clinical attachment level (CAL), bone loss, and mucosal recession (MR). Two independent reviewers conducted data extraction and quality assessments, considering short-term (<6 months) and long-term (≥6 months) follow-up periods. After screening, ten articles were included in the meta-analysis. In nonsurgical peri-implant disease management, air-polishing moderately mitigated short-term PI/PS for peri-implant mucositis and showed a similar improvement in long-term BOP and bone loss for peri-implantitis compared to the control group. The Egger test found no evidence of publication bias except for the long-term PI/PS of peri-implant mucositis. Leave-one-out analysis confirmed the stability of the results. The findings highlight the need for future research with longer-term follow-up and high-quality, multi-center, large-sample RCTs.

Experimental models for peri-implant diseases: a narrative review.

OBJECTIVES: Peri-implant diseases, being the most common implant-related complications, significantly impact the normal functioning and longevity of implants. Experimental models play a crucial role in discovering potential therapeutic approaches and elucidating the mechanisms of disease progression in peri-implant diseases. This narrative review comprehensively examines animal models and common modeling methods employed in peri-implant disease research and innovatively summarizes the in vitro models of peri-implant diseases. MATERIALS AND METHODS: Articles published between 2015 and 2023 were retrieved from PubMed/Medline, Web of Science, and Embase. All studies focusing on experimental models of peri-implant diseases were included and carefully evaluated. RESULTS: Various experimental models of peri-implantitis have different applications and advantages. The dog model is currently the most widely utilized animal model in peri-implant disease research, while rodent models have unique advantages in gene knockout and systemic disease induction. In vitro models of peri-implant diseases are also continuously evolving to meet different experimental purposes. CONCLUSIONS: The utilization of experimental models helps simplify experiments, save time and resources, and promote advances in peri-implant disease research. Animal models have been proven valuable in the early stages of drug development, while technological advancements have brought about more predictive and relevant in vitro models. CLINICAL RELEVANCE: This review provides clear and comprehensive model selection strategies for researchers in the field of peri-implant diseases, thereby enhancing understanding of disease pathogenesis and providing possibilities for developing new treatment strategies.

Diagnostic value of aMMP-8 and azurocidin in peri-implant sulcular fluid as biomarkers of peri-implant health or disease.

OBJECTIVE: The objective of this study was to investigate the effectiveness of testing for active matrix metalloproteinase-8 (aMMP-8) by a quantitative point-of-care (PoC), chairside lateral flow immunotest and azurocidin, in the peri-implant sulcular fluid (PISF), as biomarkers for the presence or absence of peri-implant diseases. BACKGROUND: Current research indicates that proinflammatory cytokines and extracellular matrix-degrading enzymes may be of value to diagnose and predict peri-implant disease initiation and progression, but more data are needed. METHODS: Eighty patients with implants were recruited. PISF samples were collected and quantitatively analyzed for aMMP-8 (chairside) and azurocidin with ELISA. Radiographic assessments and clinical indices (probing depth, probing attachment level, bleeding on probing, and plaque) were recorded after sampling. Kruskal-Wallis test and pairwise post hoc Dunn-Bonferroni test were used to relate aMMP-8 levels and azurocidin levels to clinical parameters. The diagnostic ability of aMMP-8 (ng/mL) and azurocidin was analyzed by receiver operator curve analysis. Area under the curve (AUC) was calculated and the Spearman's rho, and the coefficient of determination (R2) were used to calculate the correlations between aMMP-8, azurocidin, and periodontal parameters. RESULTS: Statistically significant differences were observed for aMMP-8 levels but not for azurocidin between healthy implants, implants with mucositis, and those with peri-implantitis (13.65 ± 7.18, 32.33 ± 21.20, and 73.07 ± 43.93 ng/mL, respectively), (Kruskall-Wallis test p < .05). The aMMP-8 test with a threshold of 20 ng/mL has a sensitivity of 71.7% and a specificity of 77.8% to identify peri-implantitis and healthy implants, respectively. AUC was found to be 0.814, and the accuracy of the method reaches 73.8%. Above a cutoff value of 33.7 ng/mL of aMMP-8, the accuracy of the test to detect peri-implantitis reaches 77.5% in relation to 62.5% of BoP from the same site. CONCLUSION: Taken collectively, present data indicate that the aMMP-8 PoC lateral flow immunotest can be a beneficial, adjunctive diagnostic quantitative tool for real-time screening for peri-implant diseases.

Diagnostic potential of endothelin-1 in peri-implant diseases: a cross-sectional study.

PURPOSE: This study aimed to evaluate the potential of Endothelin-1 (ET-1), a peptide derived from vascular endothelial cells, as a biomarker for diagnosing peri-implant diseases. METHODS: A cohort of 29 patients with a total of 76 implants was included in this study and subsequently divided into three groups based on peri-implant clinical parameters and radiographic examination: healthy (peri-implant health) (n = 29), mucositis (n = 22), and peri-implantitis (n = 25) groups. The levels of ET-1 (ρg/site) and interleukin (IL)-1ß (ρg/site) in peri-implant sulcus fluid (PISF) samples were determined using enzyme immunoassay. Statistical analyses were conducted using Kruskal-Wallis and Steel-Dwass tests. Logistic regression and receiver operating characteristic (ROC) curve analyses were performed to evaluate the diagnostic performance of the biomarkers. RESULTS: ET-1 levels were significantly elevated in the peri-implantitis group compared to those in the healthy group, and were highest in the peri-implant mucositis group. Additionally, IL-1ß levels were significantly higher in the peri-implantitis group than those in the healthy group. ROC curve analysis indicated that ET-1 exhibited superior area under the curve values, sensitivity, and specificity compared to those of IL-1ß. CONCLUSIONS: Our findings suggest that the presence of ET-1 in PISF plays a role in peri-implant diseases. Its significantly increased expression in peri-implant mucositis indicates its potential for enabling earlier and more accurate assessments of peri-implant inflammation when combined with conventional examination methods.

Diagnostic methods/parameters to monitor peri-implant conditions.

The diagnostic accuracy of clinical parameters, including visual inspection and probing to monitor peri-implant conditions, has been regarded with skepticism. Scientific evidence pointed out that primary diagnostic tools (chairside) seem to be highly specific, while their sensitivity is lower compared with their use in monitoring periodontal stability. Nonetheless, given the association between pocket depth at teeth and implant sites and the aerobic/anaerobic nature of the microbiome, it seems plausible for pocket probing depth to be indicative of disease progression or tissue stability. In addition, understanding the inflammatory nature of peri-implant diseases, it seems reasonable to advocate that bleeding, erythema, ulceration, and suppuration might be reliable indicators of pathology. Nevertheless, single spots of bleeding on probing may not reflect peri-implant disease, since implants are prone to exhibit bleeding related to probing force. On the other side, bleeding in smokers lacks sensitivity owing to the decreased angiogenic activity. Hence, the use of dichotomous scales on bleeding in the general population, in contrast to indices that feature profuseness and time after probing, might lead to false positive diagnoses. The definitive distinction between peri-implant mucositis and peri-implantitis, though, relies upon the radiographic evidence of progressive bone loss that can be assessed by means of two- and three-dimensional methods. Accordingly, the objective of this review is to evaluate the existing clinical and radiographic parameters/methods to monitor peri-implant conditions.

Patient-, implant- and prosthetic-related factors on peri-implant mucositis and bone loss.

Peri-implant diseases, including peri-implant mucositis (PIM) and peri-implantitis, are a chronic inflammatory disorder triggered by bacterial biofilm in susceptible hosts. Potential risk factors for peri-implant diseases include smoking, dental plaque accumulation, poor oral hygiene, genetics, and absence of peri-implant keratinized mucosa. This cohort study aimed to evaluate the influence of patient-, implant-, and prosthetic-related factors on PIM and peri-implant bone loss (PBL) around dental implants after 1 year of loading. A total of 54 subjects (22 males and 32 females) were included in the study. Peri-implant clinical parameters were assessed and standardized periapical radiographs of each dental implant were obtained 15 days after the definitive prosthesis installation (baseline) and at 3, 6, and 12 months of follow-up. A total of 173 implants were evaluated. PIM affected 44.8% of the implants and no significant association was found between the investigated parameters and PIM incidence, except for type of implant connection. A significantly higher incidence of PIM (80.0%) was observed for implants with internal hexagon connection type after 1 year of follow-up (p = 0.015). Moreover, a mean PBL of 0.35 ± 1.89 mm was observed and no dental implant was affected by peri-implantitis after 1 year of function. No specific influence of patient, implant, or prosthetic factors on PBL was observed. No association was found between the occurrence of PIM/PBL and the patient-, implant-, and prosthetic-related factors investigated in this cohort study, except for the type of dental-implant connection.

Immediate dental rehabilitation in fibula free flaps for malignancy: Is it feasible?

BACKGROUND: Fibula free flap reconstruction has revolutionized maxillofacial reconstruction. While immediate dental rehabilitation with dental implants and teeth has shown benefits, it remains uncommon, especially for patients with malignancy. METHODS: A retrospective cohort study at a single institution explored immediate dental rehabilitation in fibula flaps for patients with malignant disease. Thirteen patients with malignancies that underwent immediate fibula free flap reconstruction with dental implants and dental prosthesis were included with a minimum of 3-month follow-up. RESULTS: Forty eight implants replaced 90 teeth in 13 patients. All implants were integrated at 3 months, with an overall success rate of 87.5%. Two patients experienced delayed (>3 months postoperatively) implant loss due to osteoradionecrosis and infection. Peri-mucositis occurred in three patients which resolved with treatment. Skin paddles were used in 11 patients and radiation therapy was not delayed for any patient. CONCLUSION: With proper patient selection, diagnosis of malignancy and the need for osteocutaneous flap reconstruction does not exclude the ability to place immediate implants and deliver an immediate dental prosthesis in head and neck reconstruction.

Stabilized oral lichen planus does not compromise dental implants survival: A systematic review and meta-analysis.

BACKGROUND: This study aimed to evaluate the incidence of implant failure in patients with oral lichen planus (OLP) and investigate the potential association between OLP and peri-implant diseases. MATERIALS AND METHODS: Embase, Web of Science, PubMed, and Scopus databases were searched for studies with no time restrictions. Meta-analysis was performed calculating pooled proportion of peri-implantitis (PI), peri-implant mucositis (PIM), and bleeding on probing (BOP) prevalence using fixed-effects model. Odds ratio and corresponding 95% CI were calculated to assess the potential risk of PI, PIM, and BOP in dental implant patients with OLP compared to healthy controls. RESULTS: Implant failure rate was 4.38% at the patient level and 4.37% at the implant level. Six patients (3.92%) from five studies were diagnosed with oral cancer after receiving implant. The prevalence of PI, PIM, and BOP at the implant level were 14.00%, 20.00%, and 40.00%, respectively. There was no significant difference in the occurrence of PI and PIM between OLP patients and healthy controls. CONCLUSIONS: Stabilized OLP is not considered a significant risk factor for peri-implant diseases. It is advised against placing implants or prostheses during the acute phase of the disease. Histopathological investigation to differentiate OLP from oral lichenoid dysplasia is crucial.

Decision-making on peri-implant mucositis management and treatment approaches.

Peri-implant mucositis is characterised by inflammation of soft tissues surrounding a dental implant without associated bone loss beyond initial remodelling. Early detection and timely intervention are critical to prevent its progression to peri-implantitis. This paper focuses on various treatment options for treating peri-implant mucositis. The cornerstone of professional treatment lies in the mechanical disruption and removal of microbial biofilms around the implant. This can be achieved through careful use of manual or powered instruments, such as ultrasonic scalers or air polishing devices. However, there is a need for further research to determine the most effective single approach for treating peri-implant mucositis. Current evidence does not support the combination of mechanical debridement with locally administered antibiotics. Contrarily, evidence strongly supports the removal, cleaning, and modifications of prostheses to improve both self-performance and professional cleanability. The use of adjunctive therapies like photodynamic therapy and diode laser, in conjunction with mechanical instrumentation, is not currently recommended due to the limited strength of available evidence. Preventive measures emphasise the importance of comprehensive oral hygiene care, encompassing professional guidance and at-home practices, to manage biofilms effectively. This encompasses oral hygiene instruction, regular debridement, and maintenance care. Supporting peri-implant therapy is also vital for ongoing implant monitoring, preventing the recurrence of mucositis, and halting its progression to peri-implantitis. This multifaceted approach is key to effectively managing and treating peri-implant mucositis.

Peri-implant diseases and systemic inflammation: A preliminary analysis from a cross-sectional survey of patients with hypertension.

BACKGROUND: The aim of this study was to investigate the association between peri-implant diseases and systemic inflammation assessed by serum C-reactive protein (CRP) levels in a sample of patients with hypertension. METHODS: A total of 151 participants with hypertension were included in a cross-sectional study. The population was divided into six groups according to their peri-implant and periodontal status (healthy controls, mucositis, peri-implantitis, periodontitis, periodontitis and mucositis, periodontitis, and peri-implantitis). Linear, logistic regression, and correlation analyses were performed. RESULTS: CRP levels were statistically significantly higher in participants with periodontitis alone (median 3.2 mg/L, interquartile range [IQR] 1.8, p = 0.012), combined with mucositis (3.10 mg/L, IQR 2.35, p < 0.001) or peri-implantitis (2.7 mg/L, IQR 2.53, p = 0.002) when compared to the healthy controls (1 mg/L, IQR 1.2). This association was independent of age, sex, smoking status, and adiposity differences. Participants with periodontitis with and without peri-implant diseases had the greatest odds of exhibiting CRP > 3 mg/L (odds ratio = 7.3, 95% confidence interval 1.6-33.9). CONCLUSIONS: Peri-implant diseases are associated with systemic inflammation, but the nature of the association should be further investigated.

Peri-implant mucositis and peri-implantitis: key features and differences.

Peri-implant diseases are frequent complications that occur around osseointegrated endosseous implants and are the result of an imbalance between the bacterial challenge and host response. Peri-implant diseases may affect the peri-implant mucosa only (peri-implant mucositis) or also involve the supporting bone (peri-implantitis). Early detection of peri-implant diseases and timely treatment is important for the success of dental implant treatment. Peri-implant probing is essential to assess the peri-implant health status and should be done at each recall visit. Dental practitioners should be familiar with the clinical and radiological features of both conditions in order to make an accurate diagnosis and determine the appropriate treatment required. This article aims to provide clinicians with an understanding of the key differences between peri-implant health, peri-implant mucositis and peri-implantitis.

BSP Implementation of Prevention and Treatment of Peri-implant Diseases - The EFP S3 Level Clinical Practice Guideline.

OBJECTIVES: to adapt the supranational European Federation of Periodontology (EFP) Prevention and Treatment of Peri-implant Diseases - The EFP S3 Level Clinical Practice Guideline for UK healthcare environment, taking into account a broad range of views from stakeholders and patients. SOURCES: This UK version, based on the supranational EFP guideline [1] published in the Journal of Clinical Periodontology, was developed using S3-level methodology, combining assessment of formal evidence from 13 systematic reviews with a moderated consensus process of a representative group of stakeholders, and accounts for health equality, environmental factors and clinical effectiveness. It encompasses 55 clinical recommendations for the Prevention and Treatment of Peri-implant Diseases, based on the classification for periodontal and peri-implant diseases and conditions [2]. METHODOLOGY: The UK version was developed from the source guideline using a formal process called the GRADE ADOLOPMENT framework. This framework allows for adoption (unmodified acceptance), adaptation (acceptance with modifications) and the de novo development of clinical recommendations. Using this framework, following the S3-process, the underlying evidence was updated and a representative guideline group of 111 delegates from 26 stakeholder organisations was assembled into four working groups. Following the formal S3-process, all clinical recommendations were formally assessed for their applicability to the UK and adoloped accordingly. RESULTS AND CONCLUSION: Using the ADOLOPMENT protocol, a UK version of the EFP S3-level clinical practice guideline for the Prevention and Treatment of Peri-implant Diseases was developed. This guideline delivers evidence- and consensus-based clinical recommendations of direct relevance to the UK healthcare community including the public. CLINICAL SIGNIFICANCE: The S3-level-guidelines combine evaluation of formal evidence, grading of recommendations and synthesis with clinical expertise of a broad range of stakeholders. The international S3-level-guideline was implemented for direct clinical applicability in the UK healthcare system, facilitating a consistent, interdisciplinary, evidence-based approach with public involvement for the prevention and treatment of peri-implant diseases.

Tratamento da periimplantite por meio da descontaminação do implante: um relato de caso / Treatment of peri-implantitis through implant decontamination: a case report

Os implantes dentários osseointegrados representam uma parte da reabilitação oral, sendo uma alternativa cada vez mais utilizada na Odontologia a fim de substituir dentes perdidos. À semelhança das doenças periodontais, o fator etiológico das doenças periimplantares é o acúmulo de biofilme ao redor dos implantes dentários. Esta patologia também é classificada de acordo com os tecidos acometidos por ela, em mucosite e periimplantite. Para um correto tratamento e sucesso na terapia periimplantar, o diagnóstico deve ser baseado na sua etiologia e, seu tratamento segue variando de acordo com cada caso e estágio da doença. O presente trabalho tem como objetivo relatar o tratamento de um caso de periimplantite por meio da descontaminação da superfície do implante através de uma cirurgia de acesso. Paciente leucoderma, com 56 anos, sexo feminino, procurou atendimento no curso de graduação em Odontologia do centro Universitário da Serra Gaúcha ­ FSG, com queixa de sangramento/supuração, dor e edema na região dos dentes 15 e 16, reabilitados com implantes, e exposição de componentes protéticos. A paciente foi diagnosticada com periimplantite. O plano de tratamento proposto foi de promover a descontaminação da superfície do implante por meio de acesso cirúrgico. Com base no caso clínico apresentado, foi possível concluir que a técnica de tratamento utilizada foi eficaz para a resolução da periimplantite, no período de acompanhamento do estudo (90 dias), demonstrando melhora nos parâmetros clínicos e radiográficos(AU)

Osseointegrated dental implants represent a part of oral rehabilitation, being an increasingly used alternative in Dentistry in order to replace lost teeth. Similar to periodontal diseases, the etiological factor of peri-implant diseases is the accumulation of biofilm around dental implants. This pathology is also classified according to the tissues affected by it, in mucositis and peri-implantitis. For a correct treatment and success in peri-implant therapy, the diagnosis must be based on its etiology, and its treatment continues to vary according to each case and stage of the disease. The present work aims to report the treatment of a case of peri-implantitis through the decontamination of the implant surface through an access surgery. Caucasian female patient, 56 years old, sought care at the graduation course in Dentistry at Centro Universitário da Serra Gaúcha ­ FSG, complaining of bleeding/suppuration, pain and edema in the region of teeth 15 and 16, rehabilitated with implants, and exposure of prosthetic components. The patient was diagnosed with peri-implantitis. The proposed treatment plan was to promote decontamination of the implant surface through surgical access. Based on the presented clinical case, it was possible to conclude that the treatment technique used was effective for the resolution of periimplantitis, in the follow-up period of the study (90 days), demonstrating improvement in clinical and radiographic parameters(AU)
