This study aims to observe the effects of keratinized mucosa width on peri-implant tissues by evaluating clinical and biochemical parameters. The main question it aims to answer is: Would increasing the width of the keratinized mucosa with free gingival graft (FGG) in peri-implant mucositis be beneficial in terms of clinical periodontal parameters and peri-implant crevicular fluid levels of inflammatory cytokines compared to non-surgical therapy alone? Our study consists of 4 groups: Peri-implant healthy group with sufficient keratinized mucosa (≥ 2mm) (n=16), peri-implant mucositis group with sufficient keratinized mucosa (n=16), peri-implant mucositis group with insufficient keratinized mucosa (\< 2mm) receiving only non-surgical treatment (n=16), peri-implant mucositis group with insufficient keratinized mucosa receiving FGG in addition to non-surgical treatment (n=16). Clinical and biochemical measurements will be recorded at the baseline, 1st month, 4th month and 7th month of the study. Peri-implant crevicular fluid samples will be collected at baseline, 1st month, 4th month and 7th month. IL-1β, RANKL, OPG levels, and RANKL/OPG ratio will be analyzed from collected samples. Researchers will evaluate the possible benefits of FGG application in addition to non-surgical therapy by comparing the biochemical and clinical changes in areas with and without FGG application in the treatment of peri-implant mucositis.

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.
NCT06137846
The investigators are evaluating the therapeutic outcomes of two cleaning instruments on treating peri-implant mucositis. Peri-implant mucositis is inflammation around an implant that is limited to only the gum tissue and is characterized by bleeding on probing, pus, and without any evidence of bone loss. The investigators wish to compare the amount of inflammation and bacteria through measurements (like probing depth) and by collecting fluid and plaque samples around participants' implant after using one of the two cleaning instruments.
NCT07047261
The peri-implant mucositis is an inflammatory and reversible lesion that surrounds the peri-implant mucosa without loss of supporting bone, clinically characterized by bleeding on gentle probing. It has been estimated that it affects approximately 21% to 88% of individuals and 9% to 51% of implant sites, with prevalences of 47% and 29%, respectively. Experimental clinical researches show that peri-implant mucositis can be reversed if proper biofilm management is maintained. Prevention and regression of inflammation around the implant can be achieved through proper oral hygiene and an effective supportive care protocol, which may include regular clinical check-ups, radiographic assessments, oral hygiene instructions and professional mechanical plaque removal (PMPR). Therefore, adjunctive measures such as self-administration of oral rinse antiseptics (i.e. chlorhexidine) may be considered. For examples, the use of a chlorhexidine-based gel in combination with xanthan (XanCHX), in addition to PMPR has demonstrated clinical improvements in the treatment of periodontitis. The aim of the present study was to investigate the potential benefits of XanCHX gel in adjunction to PMPR in patients affected by peri-implant mucositis, promoting a complete healing of the affected tissues.
NCT06392256
The goal of this randomized clinical study is to investigate the impact of soft tissue phenotype modification following free gingival grafting (FGG) in addition to the non-surgical mechanical therapy of peri-implant mucositis (PM) with keratinized mucosa width (KMW) \< 2 mm over a 6-month follow-up period. Therefore, the following questions related to the study are raised: • Does soft tissue modification following free gingival grafting around the implants with KMW \< 2 mm, in addition to non-surgical mechanical therapy of PM, affect the change in bleeding on probing and the rate of complete disease resolution? Patients who apply to the Department of Periodontology, Faculty of Dentistry, Gazi University, are systemically healthy, have implant-supported restorations installed at least one year prior to their enrollment, and are diagnosed with PM on these implants will be selected for the study. Patients with KMW \< 2 mm at the respective implant sites will be treated with non-surgical mechanical treatment combined with soft tissue augmentation with FGG or non-surgical mechanical treatment alone.
NCT06915623
This study aims to evaluate a gel's potential to improve gum health around dental implants when used alongside traditional cleaning methods. The central research question is: Does the gel reduce gum bleeding? Researchers will compare the effects of traditional dental cleaning alone wit those of dental cleaning combined with gel administration, focusing on overall gum health around implants. The study will enroll eight participants-some with early gum issues, such as bleeding gums, and others with healthy gums. Each participant will be randomly assigned to receive either regular dental cleaning or the cleaning paired with gel application. The study process includes the following steps: 1. Participants will visit the clinic and receive one of the two treatments randomly. 2. One week later, they will complete a printed survey detailing any symptoms or discomfort experienced . 3. After four weeks, participants will return to the clinic for checkups and tests to measure progress.
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
NCT05356806
the objective of this study is to determine the incidence of peri-implant mucositis in patients with treated periodontitis and enrolled in periodontal maintenance and to evaluate the associated risk indicators. An analytical prospective observational study will be carried out, with an initial follow-up of 12 months.
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.
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.
NCT05800795
The attachment of peri implant soft tissue to the implant serves as a biological seal that can prevent the development of inflammatory peri-implant diseases. Presence of contaminants has been suggested to be associated with tissue damaging inflammation and titanium wear microparticles were demonstrated to activate osteoclastic action. Er: YAG laser has been extensively investigated clinically for applications for treating periimplantitis either independently or in combination with other techniques, showing favorable outcomes. Plasma spray treatment can decontaminate surfaces without modifying their topography. It is also able to increase the surface energy by obtaining more hydrophilic surfaces, which may increase the capacity of the titanium oxide layer to interact with cells and proteins of surrounding tissue improving cell adhesion to the treated surface.
NCT05332327
Various types of periodontal probes (e.g., metal probes, plastic/bendable probes, electronic periodontal probes) are used for peri-implant pocket depth registration; however, depending on the shape and size of the prosthetic restoration an accurate peri-implant pocket registration might be impeded with standard metal probes. There is currently no systematic assessment of which probe is more accurate in peri-implant pocket registration. Therefore, peri-implant pocket registration of 50 patients with a screw-retained prosthetic restoration will be recorded with 3 different periodontal probes; i.e., with a metal probe, with a plastic probe, and with an automatic periodontal probe, before and after removal of the prosthetic restoration.
NCT05758103
Mechanical debridement is the traditional method for the treatment of peri-implant mucositis and its success depends on the patient's correct oral hygiene. It is believed that probiotics may help by their ability to modulate the oral biofilm, resulting in anti-inflammatory and anti-bacterial plaque action. The aim of this study is to evaluate the adjuvant effect of the probiotic Limosilactobacillus reuteri in the mechanical treatment of peri-implant mucositis. This study aims to include 32 subjects with implant-supported total rehabilitation and peri-implant mucositis, divided into test and control groups, equally subjected to professional mechanical debridement, with the administration of a daily GUM® PerioBalance® lozenge for 30 days added to the test group. Plaque Index, Bleeding Index and probing pocket depth are evaluated before the intervention (baseline) and at 6 and 10 weeks later.
