Filter by:The goal of this clinical trial to test the effect of periimplant soft tissue phenotype in the participants with implant placed and at least 1 year after implant loading. The main questions it aims to answer are: 1. Is keratinized mucosal thickness (KMT) important in early marginal bone loss and peri implant health? 2. Is keratinized gingival width (KGW) important in early marginal bone loss and and peri implant health? The researchers plan to include 80 implants in the study. These 80 implants will be divided into 2 groups in 2 different ways according to their KMT and KGW on their buccal surfaces: KMT ≥2 mm are included in the adequate KMT, and those with KMT<2 mm are in the insufficient KMT group. Those with KGW≥2 mm are adequate KGW, those with KGW<2 mm are adequate KGW. The researchers will assess marginal bone loss around the implant using radiographs and collect peri-implant crevicular fluid (PICF) using paper strips. Another researchers will measure the Receptor Activator Of Nuclear Factor-Kappa B Ligand (RANKL), Osteoprotegerin (OPG), Tumor Necrosis Factor Alpha (TNF-α), MicroRNA-223 (MiRNA-223), MicroRNA-27a (MiRNA-27a) levels in the collected PICF. They will compare radiographic bone loss and biomarker levels in groups.
Various risk factors defined in the literature should be eliminated in order for the patient to be able to use implant-supported prostheses for a longer period of time. In the literature, such a diagram for peri-implant risk factors was first described by Heitz-Mayfield in 2020. The scheme that will determine the peri-implant risk diagram is called "Implant Disease Risk Assessment (IDRA)". This tool provides evaluation of various risk factors on a single diagram. In this study, peri-implant risk diagrams will be determined by calling the patients who have previously completed implant treatment in Kütahya University of Health Sciences Faculty of Dentistry Department of Periodontology, and the change in the risk profile assessment will be re-evaluated after the risk factors that can be eliminated are eliminated. In this study, it is aimed to predict the risk of inflammation and alveolar bone loss of the tissues around the implant that may occur in the future in patients who have undergone dental implant treatment, and to evaluate the risk profiles.
One of the criteria used for long-term implant success is the evaluation of radiographic bone loss. It is known that the keratinized mucosa over the alveolar crest forms a protective barrier against inflammatory infiltration. In addition, it has been reported that the vertical mucosal thickness on the crest is important in the formation of the biological width around the implant. The aim of this study was to evaluate the effect of vertical mucosal thickness on the alveolar crest on peri-implant marginal bone loss around crestal and subcrestal placed platform-switching implants. In this study, patients will be divided into 2 main groups with vertical mucosal thickness of 2 mm and less and more than 2 mm, and both groups will consist of 2 subgroups as crestally and subcrestally according to the implant level placed. A total of 80 implants will be included, 20 implants in each group. Before starting the surgery, after anesthesia is given, the width of the patient's peri-implant keratinized mucosa and the vertical mucosal thickness over the alveolar crest will be measured. Clinical and radiological measurements will be made in all patients during the prosthetic loading session (T0), at 3rd month (T1), 6th month (T2) and 1 year after loading (T3). With standardized control periapical radiographs to be taken as a result of one-year follow-up, the marginal bone loss amount in the implants will be evaluated using soft-ware.
This study was designed as a 12-month, two arms, randomized clinical trial to evaluate the efficacy of a supportive treatment protocol (SPIT). Thirty patients were randomized, six months after access-flap surgery, in two different SPIT groups. After ultrasonic debridement, the affected implant surfaces of the test group were treated with glycine powder air-polishing, while implants in the control group a rubber cup and polishing paste was used. Maintenance visits were carried every 3 months and clinical, radiological, microbiological and biochemical variables were registered at baseline (6 months after surgery) and after a follow-up period of 12 months (18 months after surgery).
Objectives: To identify patient and implant indicators influencing the non-surgical therapeutic outcomes of peri-implantitis at 6-months follow-up. Material and methods: This prospective cohort study included patients with at least one implant diagnosed with peri-implantitis according to the 2017 World Workshop. Non-surgical therapy consisted in a mechanical debridement of the peri-implant pockets combined with the metronidazole 500 mg every 8 hours during 7 days. At baseline and at 6 months, clinical and radiographic variables were collected to calculate the success of the therapy. The influence of patient and implant/prosthetic variables on disease resolution were assessed trough simple and multiple logistic regression analysis at patient and implant level using generalized estimation equations models.
The existing records of a private practice limited to the practice of periodontology were reviewed to locate patients who had been diagnosed with peri-implantitis (failing dental implant) and had been surgically treated utilizing enamel matrix derivative (Commercially available FDA product Emdogain sold by Straumann USA). Various clinical factors were gathered from the existing records. Some of the factors recorded were: retention of the implant, presence of bleeding, presence of further damage, and presence of inflammation. All patients had signed an informed consent for treatment and the anonymous use of their data for research purposes. All HIPA requirements were followed.
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.
Smoking is a major risk factor for developing peri-implantitis so the current study is comparing inflammatory markers in smokers versus non smokers to know if they have a potential role in pathogenesis of peri-implantitis
Macrophage surface markers (CD80, CD163 and CD206) will be evaluated in periodontally healthy gingiva, healthy peri-implant mucosa, and periodontitis and peri-implantitis lesions.
Photodynamic therapy (PDT) is suggested as an adjuvant treatment method to the surgery in peri-implantitis treatment. The primary goal of peri-implantitis therapy is the removal of the causative bacteria from the implant surface and surrounding tissues in order to improve the process of re-osseointegration and achieve long term implant stability. Accordingly, the aims of the study were to evaluate clinical, immunological and microbiological outcomes after surgical therapy of peri-implantitis following PDT.
