Active clinical trials for "Peri-Implantitis"

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.

The primary objective of the study is to proof the successful use of Geistlich Bio-Oss® and Geistlich Bio-Gide® (already registered medical devices) in bony peri-implant defects due to peri-implantitis disease.

Lack of keratinised mucosa around dental implants and teeth is associated with plaque accumulation and worse tissue conditions. However, there is lack of data on the influence of the presence/lack of keratinised mucosa on the periodontal condition. Hence, soft tissue conditioning by grafting with a gingival graft is aimed at improving the quality of the peri-implant conditions

Objective: The objective of this study was to evaluate a new mechanical method (Ti-Brush, Straumann, AG, Basel, Switzerland) of implant surface decontamination. Material and methods: A randomized double-blinded controlled clinical trial with a 1-year follow-up it is being carried out. After a hygienic phase, defects were randomly assigned to a control (n=18) or to a test group (n=18). In control group, implant surface was decontaminated both mechanically and chemically with 3% H2O2 and plastic ultrasonic scalers, respectively, while in test group Ti-Brush was added. Infrabony defects in both groups were regenerated with BoneCeramic (Straumann, AG, Basel Switzerland) and collagen barrier membrane Cytoplast (Osteogenics, Lubbock, United States). Clinical and radiographic parameters were measured at baseline, 6, and 12 months after surgery.

In this study genomic, proteomic and histological technologies for the search and characterization of epigenetic modifications and molecular or protein markers, useful in the diagnosis and progression of peri-implant diseases and prevention of implant failure will be used.

The purpose of the study is to evaluate if using Erbium-doped yttrium aluminium garnet laser, Erbium YAG laser (Er:YAG) laser could have adjunctive benefits to the conventional standard mechanical debridement to ablate the infected tissue around the dental implant and detoxify the contaminated implant surface for resolving peri-implant infection and enhance bone regeneration of peri-implant defects.

20 consecutive adult implant patients, presenting the signs of peri-implant mucositis (probing depth ≥4 mm combined with bleeding and/or pus on probing) or initial peri-implantitis (probing depth ≥4 mm, bleeding and suppuration plus radiographic loss of supporting bone ≤30% compared with the situation after implant placement) will be included. Sites will be treated by ultrasonic debridement of the pocket, performed using a piezoceramic ultrasonic device. For the purpose, a Tip will be connected to the Handpiece Led (5 minutes/pocket) . Then, it will be followed by the subgingival use of erythritol powder applied by the use of Handpiece connected to an airflow unit 2x5 seconds/pocket. At this time the subgingival delivery of metronidazole gel will be provided. After instrumentation, patients will rinse with chlorhexidine 0.20% 3 times/day for 2 weeks. At baseline, 1 month, 3 months and 6 months the following parameters will be evaluated: Probing Pocket depth (PPD), Bleeding on Probing (BoP), Clinical Attachment Level (CAL).

The primary purpose of this study is to determine what effect, if any, do different dental materials used to seal the prosthetic screw channels of implant supported restorations have on dental implant health parameters and microbiology.

Communication strategies are encouraged to enhance patients´ understanding of potential events related to implant therapy such as peri-implantitis. Moreover, it is key to provide accurate information to patients receiving dental implants to reduce false expectations and to minimize the alterations concerning satisfaction. Information leaflets based in the "health-belief model" proved efficiency in improving health judgments, decisions and behaviors, in particular when supplemented with visual aids. Hence, it was the purpose of the present study to test the effectiveness of different communication strategies to enhance and modulate the understanding and memorization of risk indicators associated to peri-implantitis. A prospective randomized controlled three-arm study is being conducted in accordance with the Declaration of Helsinki on human studies. Three groups are defined to test the hypothesis that visual aids improve the understanding, modulation and memorization of peri-implantitis and related indicators as follows: Test group1 - Leaflet with visual aid (L-VA): Information concerning etiology, prevalence, risk indicators and preventive measures of peri-implantitis were included (supplementary figure 1). Relevant scientific bibliography supported the statements. Along, pictograms were supplemented to display the prevalence of disease with and without the known indicator. Test group2 - Leaflet with visual aid (L-NVA): Information concerning etiology, prevalence, risk indicators and preventive measures of peri-implantitis were included (supplementary figure 2). Relevant scientific bibliography supported the statements. No pictograms were supplemented. Control group - No leaflet (NL): Only verbal information was provided to the patient during initial interview. Patients will be randomly assigned to the tests or control groups according to the last digit of their chart number. As such, patients with records ending 1-4, 4-7 and 8-0 were included in test group1, test group2 and control group, respectively. When reached the total sample size of any of the groups, patients were only recruited for the remaining groups to complete the total sample size. A questionnaire based on the "health-belief model" will be collected from every eligible patient at baseline, 3- and 6-month follow-up

Objective: This study aimed to evaluate the total amounts of tumor necrosis factor α (TNF-α), prostaglandin E2 (PGE2), receptor activator of nuclear factor kappa B ligand (RANKL), receptor activator of nuclear factor kappa B (RANK), and osteoprotegerin (OPG) and the abundance of putative oral pathogens Fusobacterium nucleatum, Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, Prevotella intermedia, and Streptococcus oralis in extra short and standard dental implants functioning in the posterior mandible. Methodology: The implants were divided into two groups according to their lengths: standard (intrabony length ≥8 mm) and extra short (intrabony length ≤ 6 mm). A total of 60 implants were researched in 30 patients. Probing depth (PD), clinical attachment level (CAL), presence of bleeding on probing (BOP), 3-year survival rate (CSR), and bone loss (BL) were measured.
