Filter by:The current study aimed to investigate the effect of the combined Nd-Er: YAG laser on the surgical treatment of peri-implantitis by evaluating clinical markers and biomarkers of bone loss (RANKL/OPG). Twenty (20) patients having at least 1 implant diagnosed with peri-implantitis were randomly assigned to two groups for surgical treatment. In the test group (n=10), Er: YAG laser was used for granulation tissue removal and implant surface decontamination, while Nd: YAG laser was employed for deep tissue decontamination and biomodulation. In the control group (n=10), an access flap was applied, and mechanical instrumentation of the implant surface was performed by using titanium curettes. The following clinical parameters were evaluated at baseline and six months after treatment: Full-mouth Plaque Score (FMPS), Probing Pocket Depth (PPD), Probing Attachment Levels (PAL), recession (REC), and Bleeding on probing (BoP). Peri-implant crevicular fluid (PICF) was collected at baseline and six months for the evaluation of soluble RANKL and OPG utilizing enzyme-linked immunosorbent assay (ELISA).
Objectives: Inflammatory lesions develop in the tissues surrounding implants are referred to as peri-implant diseases. Oxidants, play a role in inflammatory lesions. The study aimed to determine oxidant and antioxidant levels in the saliva of patients with various levels of peri-implant diseases and the relationship between oxidative stress and peri-implant diseases. Material and methods: Sixty-seven patients with at least one dental implant applied in our clinic were included in the study. The patients were divided into 3 groups; with peri-implantitis (PI), with marginal bone loss (MBL) and with healthy peri-implant (HI) tissues. Twenty-one individuals who didn't have any dental implants were included the study as a healthy control group (HC). For oxidant concentration, total oxidant status (TOS), advanced oxidation protein products (AOPP), and for antioxidant concentration, total antioxidant status (TAS), were investigated.
The goal of this observational study is to compare the prevalence of peri-implantitis between periodontitis and nonperiodontitis sites treated with alveolar ridge preservation. The main question it aims to answer is: • whether the occurrence of PI is associated with reasons for dental extraction because of periodontitis and nonperiodontitis after alveolar ridge preservation. Researchers will compare the prevalence of peri-implantitis between periodontitis and nonperiodontitis sites treated with alveolar ridge preservation.
Peri-implantitis is defined as the pathological condition around dental implants characterized by inflammation in the peri-implant mucosa and progressive bone loss, eventually leading to implant loss. Peri-implantitis is thought to be a disease analogous to periodontitis with a prevalence reaching 22%. Though peri-implantitis is readily recognized as a part of modern dentistry, the exact etiology or an effective treatment regimen hasn't been established yet. Thus, contemporary research is orientating toward acknowledging the aetiologic and risk factors of the disease and of course establishing prognostic markers for disease prevention. Microbiota residing in the subgingival plaque are considered the main etiologic factor of the disease, however, current literature has not concluded on the exact microbial composition of peri-implant lesions. In addition, genetic predisposition has been recognized as a risk factor for disease initiation and progression and several observational studies have addressed the potential association between various gene polymorphisms and the occurrence of peri-implantitis. Lastly, to establish effective preventive measures, several biomarkers have been evaluated as potential diagnostic and prognostic markers of disease progression. Objectives: 1. To identify the relationship of peri-implantitis with Cycloxygenase-2 (COX-2) and MMP-8 gene polymorphisms. Cyclooxygenase catalyzes the production of prostaglandins (PGs) which are an important inflammatory mediator participating in the pathogenesis of peri-implantitis. In addition, PGE2 expression in the peri-implant crevicular fluid will be assessed. 2. To characterize the microbiota associated with peri-implantitis lesions, using novel identification techniques enabling the identification of specific opportunistic bacteria associated with the disease. 3. To test the diagnostic accuracy of a modern chairside test, using metalloproteinase-8 (MMP-8), an enzyme implicated in the pathogenesis of the disease, as a biomarker of disease progression.
The objective of the present randomized clinical trial will be to compare two surgical methods of treating peri-implantitis. This study will determine if surgical debridement of peri-implantitis bone defects, including air decontamination of implant surfaces, in combination with the placement of a bone graft, differs in treatment outcomes compared to placing the same bone graft material with a resorbable collagen membrane placed over the bone graft.
The goal of this clinical trial is to compare non-surgical treatment by mechanical debridement with air-polishing in peri-implantitis. The main question it aims to answer is: • Does non-surgical treatment of peri-implantitis with an air-polishing devise (Perioflow® EMS, Nyon Switzerlad) provide a better treatment result than conventional cleaning with mechanical instruments? Participants will receive non-surgical treatment of peri-implantitis either with mechanical debridement and with an air-polishing devise. Researchers will compare pocket depth and bleeding/suppuration on probing in implants treated with the two methods to see if either of them is more efficient in treatment of peri-implantitis.
To report the clinical and radiographic outcomes of implant-supported fixed dental prostheses with full-ceramic cantilever extensions (FDPCs) after a function time ≥ 12 months.
The use of titanium dental implants has become a common modern treatment to restore teeth. Although the success rate of dental implants is high, inflammation around the dental implant still occurs. The current study will investigate if the inflammation around the implant is due to bacterial infection, hypersensitivity or both. The goal of this cross-sectional study is to (1) Establish the levels of cytokines in peri-implant crevicular fluid associated with bacterial infection and hypersensitivity reaction; (2) Compare the levels of cytokines associated with hypersensitivity and bacterial infection between healthy implants and inflamed implants (peri-mucositis and peri-implantitis); (3) Determine whether the difference in the levels of cytokines, if they exist, reflects the clinical diagnosis of healthy implants and inflamed implants.
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.
