This multicenter, single-masked randomized controlled clinical trial evaluates the effectiveness of minimally-invasive non-surgical therapy (MINST) compared with standard non-surgical peri-implant therapy (NSPT) in patients diagnosed with peri-implantitis. The study investigates clinical outcomes, radiographic bone levels, patient-reported outcomes, and treatment time over 12 months.
NCT07391202
The aim of this single-blind, randomized controlled clinical trial is to evaluate whether removal of the prosthetic crown influences the clinical effectiveness of non-surgical mechanical therapy in implants affected by peri-implantitis. The study is designed to compare changes in several clinical and radiographic parameters between baseline and follow-up examinations at 3, 6, and 12 months. The primary outcome measure will be the mean peri-implant probing depth (PIPD). Secondary outcomes will include changes in gingival recession (REC), radiographic marginal bone level (MBL), modified bleeding index (mBI), and additional patient-related variables.
NCT06153212
The purpose of this study is to study the use of a new type of d-PTFE membrane called reinforced PTFE Mesh (RPM) with dental surgery. The regenerative outcomes of RPM membranes and collagen membrane for surgical reconstructive treatment of peri-implantitis (gum disease around implants) will be compared.
NCT06890117
A prospective, randomized clinical trial with a 3-month duration was designed to evaluate the efficacy of non-surgical treatment for peri-implantitis. Patients presenting at the Postgraduate Periodontology Clinic of the School of Dentistry, Aristotle University of Thessaloniki, with a diagnosis of peri-implantitis in at least one implant (based on the new classification of periodontal and peri-implant diseases, EFP 2018) will be included. After clinical and radiographic evaluation, patients will be randomly assigned to two groups, with each patient participating in the study with one implant. The control group will receive non-surgical treatment using ultrasonic scalers designed for implants, combined with saline irrigation. The experimental group will undergo non-surgical treatment with Er:YAG (2940nm) and Diode (808nm) laser. All patients will receive oral hygiene instructions at baseline and during each subsequent visit. Microbial plaque samples will be collected using two sterile paper cones from the deepest peri-implant pocket before treatment and three months after treatment. The presence and absolute counts of Porphyromonas gingivalis and Filifactor alocis will be assessed using quantitative polymerase chain reaction (qPCR). Additionally, peri-implant crevicular fluid will be collected from the second deepest peri-implant pocket using three sterile paper cones before treatment and three months post-treatment for metabolomic analysis. Clinical parameters, including probing pocket depth (PPD), bleeding on probing (BOP), clinical attachment level (CAL), peri-implant mucosal recession (REC), and suppuration (SUP), will be recorded at baseline and at the end of the experimental period (3 months). Treatment success will be evaluated at the 3-month mark, defined as a pocket depth ≤5 mm with no bleeding on probing at more than one of six implant sites and no suppuration, according to the EFP S3 level clinical practice guideline. Additionally, patients will complete a home questionnaire to assess pain at different time points (immediately after treatment, 24, 48, and 72 hours post-treatment). Pain levels will be evaluated using a 100-mm visual analog scale (VAS), where 0 mm indicates "no pain" and 100 mm represents "worst pain." The total number of analgesics consumed daily for one week post-treatment will also be recorded. At the end of the week, patients will answer four Yes/No/Don't Know questions to assess their satisfaction with the treatment.
NCT07295743
The study was conducted at the Division of Periodontology, Bolu Abant İzzet Baysal University Faculty of Dentistry. Participants were systemically healthy individuals aged 18 to 70 who had received dental implant prostheses within the past five years and had high-quality panoramic radiographs. The peri-implant status of the subjects was evaluated using various indices and radiographic analyses in accordance with Chicago's Classification of Periodontal and Peri-Implant Diseases and Conditions. Additionally, measurements of gingival thickness, gingival phenotype, keratinized gingival width, and emergence angle were performed.
NCT07104760
Peri-implantitis is a pathological condition characterized by the inflammation of peri-implant connective tissues and progressive alveolar bone loss. There is a global concern about the increasing prevalence of this disease, which may affect up to 43% of implants in function. This cohort study will evaluated the long term follow up of a randomized, controlled, double-blind placebo study that evaluated the regenerative treatment of peri-implant diseases with surgical debridement and Er,Cr:YSGG AG laser associated with systemic antibiotics. A total of 80 subjects with peri-implantitis (PD\>5mm, BoP and/or sup, bone loss \>3mm) will be treated reavluated after 10years follow-up. Clinical, radiographic, and microbiological parameters will be recorded at baseline and 120 months follow-up. The primary outcome variable of this trial was be the difference between groups for the change in clinical attachment level from baseline to 6 months. We did consider composite outcomes, although not as the primary outcome. We also aim to evaluate the number and percentage of patients (and implants) reaching the following clinical endpoint for treatment: Probing depth \< 5mm, absence of bleeding on probing and no further bone loss (Heitz-Mayfield and Mombelli, 2014). The secondary variables will be the differences between groups in PI, GI, BOP, SUP and PD and microbial profile.
NCT06923748
This randomized clinical trial aims to compare the efficacy of two interproximal cleaning devices-superfloss and interdental brushes- in patients diagnosed with peri-implant diseases. The study evaluates plaque control and bleeding scores. Patients will be randomly assigned to one of two oral hygiene protocols and will be monitored through clinical examinations and validated questionnaires assessing both clinical and radiographic parameters and patient-reported outcomes.
NCT07208643
This prospective study will include patients previously enrolled in the PER-ECL-2019-05 trial who attend the Department of Periodontology (CUO) for maintenance therapy or treatment of periodontal and/or peri-implant diseases, provided they meet the inclusion criteria. Initially, 36 patients with advanced peri-implantitis were enrolled in a randomized clinical trial evaluating the clinical, radiographic and patient-related outcomes of reconstructive therapy following a non-surgical phase of peri-implantitis treatment compared to non-surgical treatment alone (PER-ECL-2019-05) (10). At the study conclusion 34 patients were re-evaluated and 2 patients were excluded from the study (10). In the original study, adult patients presenting at least one titanium implant diagnosed with peri-implantitis were identified among patients referred to the Department of Periodontology of UIC between January 2020 and October 2022. Peri-implantitis was diagnosed following the case definition of the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions (11) that is, PPD ≥ 6 mm combined with bleeding on probing (BOP) and/or suppuration (SUP), together with progressive bone loss in relation to the radiographic bone level assessment. In those cases where initial radiograph was unavailable, the definition of a peri-implantitis case was based on radiographic evidence of bone level ≥3 mm apical to the most coronal portion of the intra-osseous part of the implant (12). At the outset of the original study, participants were randomly assigned to one of two groups: The first group received only non-surgical therapy for peri-implantitis, while the second group underwent a non-surgical phase followed by reconstructive surgical treatment. This design allowed for direct comparison of the clinical, radiographic, and patient-centered outcomes between the two treatment modalities. Both groups were managed and evaluated according to standardized protocols, ensuring consistency and reliability of the results at 12 months . Patients who have not returned to the Department will be contacted by telephone and invited to participate through the academic office. At 36 months, a single follow-up will be carried out including: A detailed clinical examination. A standardized radiographic assessment.
NCT07004517
The aim of the diagnostic accuracy study was to compare the diagnostic accuracy of probing depth before (PPD-1) and following (PPD-2) the removal of prothesis in identifying the presence of peri-implantitis and assess the factors influencing peri-implant probing.
NCT06863116
Peri-implant diseases, such as peri-implant mucositis and peri-implantitis, are inflammatory conditions that affect the tissues surrounding dental implants. If untreated, these diseases can lead to bone loss and implant failure. This study investigates whether low oxygen levels (hypoxia) in the peri-implant environment influence ferroptosis, a type of cell death associated with oxidative stress. The research focuses on three key biomarkers: hypoxia-inducible factor-1 alpha (HIF-1α), glutathione peroxidase-4 (GPX-4), and malondialdehyde (MDA). A total of 45 participants with 62 dental implants were included in the study. They were divided into three groups: peri-implant health, peri-implant mucositis, and peri-implantitis. Peri-implant crevicular fluid (PICF) samples were collected, and the levels of HIF-1α, GPX-4, and MDA were measured using laboratory tests. The study aims to determine whether hypoxia affects ferroptosis-related pathways by altering GPX-4 and MDA levels. Understanding these mechanisms could provide new insights into peri-implant disease progression and help develop improved treatment strategies.
NCT06761521
68 patients underwent the aMMP-8 chair-side test as well as clinical traditional measurement methods. Those who had one or more implants in their mouth were selected as patients. The condition of the attachment tissues of these implants is monitored at a control visit after five years.
NCT06288919
The aim of the study is to assess which prophylaxis methods is the most suitable for peri-implant hygiene between erythritol and ultrasonic scaler with peek inserts. A randomized clinical trial will be conducted on the patient. Patients will be randomly divided into two groups: * Erythritol group: erythritol with a particle size of \~14 µm will be used for 5 seconds (AIRFLOW® PLUS EMS) * Ultrasonic scaler group: a piezoelectric handpiece with peek inserts (Mini Piezon EMS; PI EMS) will be used. Different subgroups will be defined according to the material of the dental crown of the related implant. The oral hygiene session will be carried out every 6 months (2-years follow-up; 6 sessions), after instruction and motivation of the patient, completion of the clinical chart with the recording of the Probing Depth (evaluation in mm of the peri-implant sulcus taken by a periodontal probe; 4 surfaces of the gingival margin are detected: vestibular, palatal/lingual, mesial, distal), Bleeding on Probing and Plaque Index.
NCT06740123
To date, systemic/local antibiotics, antimicrobials, laser application, and probiotics have been used as adjuncts to improve the outcome of non-surgical periodontal treatment for both periodontitis and peri-implantitis patients. H42® hydrogel, obtained by combining a high molecular weight hydrogel with type I collagen, is a collagen paste for regenerating periodontal/peri-implant pockets caused by periodontitis/peri-implantitis. This study aimed to clinically, biochemically, and radiologically evaluate the effect and reliability of hydrogel application into the pocket in addition to non-surgical periodontal treatment in the treatment of periodontal and peri-implant pockets. Fifteen patients with stage 2 periodontitis, each with 30 teeth and 30 implants with 5-8 mm pocket depth in the contralateral quadrants, and a total of 30 patients, will be equally divided into two groups. The test group will receive non-surgical periodontal treatment followed by H42 hydrogel application (Hydrogel Oral- 3 syr 0.4 cc/syr), while the control group will receive only non-surgical periodontal treatment. All patients will undergo the same procedure of non-surgical periodontal treatment
NCT06390124
Peri-implantitis is considered a bacteria-mediated inflammatory disease that leads to a progressive loss of support. During the last decade, research has been striving to understand this entity and strategies for primary and secondary prevention of the disease; However, all of them are about the effectiveness of different therapeutic modalities for their management. In general, it was stated that surgical therapy was ineffective in resolving inflammation. Therefore, surgical strategies are usually needed to eradicate the pathology. Taking advantage of the knowledge acquired during approximately a period of time about the surgical treatment of periodontitis, if you propose several alternatives. These are mainly based on the morphology of the defect, although other factors, such as the lack of keratinized mucosa or the habit of smoking can alter the decision-making process. As such, peri-implantitis with angular defects (i.e., defects with infraosseous components) is indicated for reconstructive measurements with no barrier membranes. On the other hand, horizontal defects (i.e., defects with supra-crestal components) are more likely to resolve by resecting therapy with or without bone contouring measures. It is interesting to note that, although early data indicated that the morphology of the peri-implantitis defect often shows a well-contained circumferential defect, it has recently been shown that it often presents a 2/3 wall defect configuration, where the buccal plate is commonly missing bone wall. The reason for this characteristic may recur in the dimension of the basal alveolar bones, insufficient critical buccal bone thickness or implant positioning13 in relation to the bone envelope. In addition, it should be noted that \~ 25% of peri-implantitis diagnosed on a daily basis exhibit a combined configuration of defects (i.e., a combination of infraosseous and supra-critical components). For their reconstructive treatment, many biomaterials have been documented, among them several protocols proposed by our research group. However, the use of biological agents or growth factors has not been investigated for a long time. Platelet Derived Growth Factor (PDGF, Platelet Derived Growth Factor) is one of several Growth Factors or proteins that regulate cell growth and Cellular Division. PDGF plays a significant role, especially for Angiogenesis, which implies the growth of blood vessels from the existing vascular tissue. Uncontrolled angiogenesis is characteristic of cancer. Chemically the PDGF is a Glucoprotein chains A (-AA) or B (-BB) or composed of them (-AB). In the field of periodontics, periodontal regeneration has been shown to be successful in obtaining radiographic bone gain and tissue regeneration.
NCT03077061
The project will evaluate the potential benefit of the use of bone replacement graft as an adjunct to surgical therapy of peri-implantitis. The project will be conducted as a two-armed randomized controlled clinical trial of 5-year duration in 7 clinical centers. 140 systemically healthy patients diagnosed with peri-implantitis will randomly assigned to be treated with or without bone replacement graft. Outcome measures include assessments of inflammation, probing depth, recession, radiological parameters and PROMs.
NCT06619158
This clinical trial is being conducted to study peri-implant mucositis (inflammation in the gums around dental implant that does not extend into the implant-supporting bone). There are currently no available treatment options able to provide long-term resolution of implant gum inflammation even with our current gold standard treatment of non-surgical cleanings and oral hygiene instructions. The purpose of the study is to compare the effect of crown glaze removal and subsequent polishing in addition to mechanical debridement compared to only mechanical debridement on the implant affected by implant gum inflammation. In this study, participants will be randomized (put into a group by chance) into one of 2 study groups, groups A and B. Group A: The implant crown will be cleaned with titanium scaling instruments and powered instruments. The screw-retained crown will be removed and the remaining build-up on the crown will be photographed. The crown will then be sent to a lab technician who will remove the glaze and polish the crown only in the areas that sit under the gums. Group B: The implant crown will be cleaned with titanium scaling instruments and powered instruments. The screw-retained crown will be removed and the remaining build-up on the crown will be photographed. The crown will then be sent to a lab technician to perform a superficial cleaning only. In both groups, the crown will be placed back on the implant and customized oral hygiene instructions will be provided. The study will require four appointment. Appointment #1 is the screening appointment and will take 30-60 minutes. Appointment #2 is when treatment is delivered and will occur within 4 weeks of appointment #1. Appointment #3 is for the short-term follow-up and will occur within 60-70 days of appointment #2. Appointment #4 is for the long-term follow-up and will occur within 12-13 months of appointment #2. All these appointment will be in an outpatient setting at the institutional graduate periodontics clinic. A total of 2 x-rays will be taken of the implant. One will be taken during appointment #1 to assess the bone around the implant. One will be taken during appointment #2 to ensure that the crown is fully seated when the crown is re-inserted. The following information will be collected in appointment #1: gum measurements around the implants, how tight the implant contacts adjacent teeth, when the crown was delivered, previous cleanings around the implant, age, sex, gender, previous systemic antibiotic use in the last 2 weeks, smoking habits, presence of diabetes and HbA1C values. At appointments #2, 3, and 4, the following information will be collected: plaque around implant, gum measurements around implants, previous systemic antibiotic use in the last 2 weeks, smoking habits, presence of diabetes and HbA1C values, gum fluid samples around the implant crown. In appointment #4, additionally, information on how the implant has been cleaned throughout the year will be collected.
NCT06128850
Except for patients with referred clinical bruxism and uncontrolled medical conditions, the study included 123 implants with implanted fixed prostheses that had lasted at least six months after functional prosthetic loading. In all implant patients, the health scale ranged from implants and natural teeth to plaque, gingival index, bleeding in the probe, mouth depth, loss of clinical attachment, and dental implants. The health and illness of the implants have been determined. Patients were divided into three groups: peri-implantitis, peri-implant mucositis, and peri-implant health. Inclusion Criteria: * Patients between the ages of 18- 70 * Drugs that have a systemically healthy and controlled treatment situation * Drivers who have implant-supported fixed prostheses that have been at least six months after functional prosthetic loading Among these groups, it was checked whether periodontitis was seen in patients with peri-implantitis, gingivitis in patients with peri-implant mucositis, and whether healthy gums were seen in individuals with peri-implant health. To determine the health and disease status of individuals' implants, plaque index (Silness Loe 1964), gingival index (Loe Silness 1963), bleeding on probing (Ainoma Bay 1975), pocket depth measurements, and clinical attachment level were collected.
NCT01852253
Peri-implantitis is a infectious disease that resides in the mucosa surrounding dental implants and also affects the supporting bone. Because the number of implants placed in everyday clinical practice is continuously increasing, is it reasonable to anticipate an increasing prevalence of peri-implantitis. This underlines the necessity for a predictable therapy. However, from the literature there is very little reliable evidence suggesting which could be the most effective interventions for treating periimplantitis. The primary objective of this controlled clinical study is to evaluate the clinical effect of decontamination of the implant surface during the surgical treatment of peri-implantitis using a 2% chlorhexidine solution or a 0.12% chlorhexidine solution. The secondary objective is to assess the microbiological effect of decontamination of the implant surface during the surgical treatment of peri-implantitis using a 2% chlorhexidine solution or a 0.12% chlorhexidine solution. The primary study parameter is the change from baseline in modified bleeding index. Secondary study parameters are: change in microbial composition of the biofilm covering the dental implant surface; microbiological composition of the peri-implant sulcus; change in probing pocket depth;change in suppuration on probing; change in radiographic marginal bone level on standardized intraoral radiographs; change in modified plaque index; implant failure, defined as implant mobility of previously clinically osseointegrated implants and removal of non-mobile implants because of progressive marginal bone loss or infection; complications and adverse events. It is hypothesized that decontamination of the implant surface with 2% chlorhexidine leads to a greater decrease in modified bleeding index than decontamination with a 0.12% chlorhexidine solution.
NCT06166017
Cross-sectional study involving the measurement of the width of lingual keratinized tissue (in the implant locations) in fully edentulous patients restored with dental implants. The width of KT will be correlated with the primary outcome, diagnosis of peri-implantitis, defined as Probing depth (PPD)\>= 6 mm, inflammation/ bleeding on probing (BOP) and bone loss \>= 3 mm from the implant platform.
NCT06109701
Implants have become a popular and widely used treatment option for treating partial and total edentulism. As the number of implants placed increases, so does the incidence of peri-implant mucositis and peri-implantitis. Placing patients under SPT/maintenance care has been shown to prevent and treat such conditions. Despite SPT's importance in prevention and infection control, adherence to scheduled SPT visits have been unsatisfactory. Understanding the reasons for non-compliance can help both the clinician and research community to address them by improving patients experience to those visits thereby increasing compliance.
