Active clinical trials for "Peri-Implantitis"

The key objective of the study is to compare the effects of soft tissue augmentation using a volume stable collagen matrix or autogenous connective tissue graft or no soft tissue augmentation in addition to bone grafting/implantoplasty in patients who undergo surgical therapy of peri-implantitis with respect to clinical resolution of the infection.

This randomized clinical trial evaluates the clinical and microbiological (microbial complexes and changes in the diversity of the submucosal biofilm) effects of MTZ+AMX as adjuncts to anti-infectious surgical treatment plus Er: YAG in the treatment of peri-implantitis.

This double arm, split-mouth, single centre, controlled, randomised clinical study is designed to examine the effect of implantoplasty in treatment of peri-implantitis. Peri-implantitis will be treated with open flap debridement, with or without implantoplasty.

To investigate the effects of peri-implantitis (a disease around dental implants) and its treatment at both local and systemic levels using clinical and biological parameters. One study with two parts which will run simultaneously. An initial observational study comparing cases and controls and a subsequent interventional study in which the cases will proceed to treatments and all participants will be followed up for 6 months.

The purpose of this study is to evaluate the clinical efficacy of ultrasonic instrumentation versus the use of an erythritol jet in the treatment of peri-implantitis.

Peri-implantitis is a pathological condition associated with plaque that develops around dental implants, characterized by inflammation and progressive bone loss in the peri-implant area. Bleeding on probing, suppuration, increased pathological pocket depths and/or mucosal recessions are seen with radiographic bone loss in peri-implantitis. When evaluated histologically, the lesion extends to the apical part of the pocket epithelium and contains a large amount of plasma cells, macrophages and neutrophils. In the Peri-implant crevicular fluid analysis, which is one of the most important parameters that enable the biochemical and immunological evaluation of the inflammatory state in the peri-implant region, information about the current inflammatory situation can be obtained by evaluating the content of an osmotic inflammatory exudate originating from the vessels in the gingival plexus. Many surgical and non-surgical methods have been proposed for the treatment of peri-implantitis. Mechanical surface debridement, laser application and air abrasives are a part of non-surgical treatment of peri-implantitis. In this study, we examined the effectiveness of diode laser in addition to mechanical debridement with titanium curettes. In our study, we aimed to compare these two treatments biochemically by determining the changes in interleukin-1β, Interleukin-10, Interleukin-17, RANKL, osteoprotegerin, TWEAK and sclerostin biomarkers in Peri-implant crevicular fluid and clinically.

The aim of this randomized clinical trial is to evaluate the effectiveness, in terms of clinical and radiographic changes, of non-surgical peri-implant therapy (mechanical/chemical) versus regenerative surgical therapy (xenograft and collagen membrane), after a follow-up period of 12 months.

Keratinized mucosa, which is composed of free gingiva and attached gingiva, is a barrier against bacterial invasion in oral cavity and provides good tissue sealing for periodontal environment. When the keratinized mucosa is insufficient, it is difficult to maintain the long-term stability of the implant, which is not conducive to the peri-implant health. It is generally believed that enough keratinized mucosa width is beneficial to reduce plaque accumulation and reduce the incidence rate of peri-implant diseases. In recent years, clinicians have gradually recognized that the thickness of keratinized mucosa plays an important role in maintaining the peri-implant health. Some researchers found that the thickness of mucosa is very important to maintain the aesthetic effect of implant restoration, and when the thickness of mucosa around the implant is less than 2mm, alveolar bone absorption will occur to maintain a stable biological width. A meta-analysis showed that when the thickness of the keratinized mucosa around the implant was greater than 2mm, the amount of marginal bone loss was significantly reduced (- 0.8mm, P < 0.0001). It is considered that autogenous soft tissue graft is the most reliable technology to augment keratinized mucosa. Subepithelial connective tissue graft (SCTG) is a mucogingival surgery that transplant autologous free connective tissue under the pedicled semi thick flap to augment keratinized mucosa. It can effectively increase the thickness of soft tissue, cover the exposed implant, and reconstruct the interdental papilla. It is the gold standard for peri-implant soft tissue agumentation. Keratinized mucosal thickening surgery may be done prior to the surgical phase, after the surgical phase, before loading, or even after loading. It is believed that keratinized mucosal thickening at the same time of implantation can effectively reduce the possibility of mucosal recession after implantation, reduce the amount of marginal bone absorption in the process of osseointegration, which is conducive to maintaining the long-term stability of the implant. For the sake of clear clinical vision and convenient operation, clinicians often choose to thicken the keratinized mucosa during the secondary operation, and also obtain good postoperative effect. However, after the completion of the final repair, the keratinized mucosa thickening surgery increases the difficulty of operation and the technical requirements for the operator. In clinical practice, it is rarely selected to perform keratinized mucosal thickening at this time. At present, the effectiveness of timing on the outcome of soft tissue augmentation is still debated, and, most importantly, a direct comparison between simultaneous and staged procedures remains underexplored. Therefore, this clinical trial is to prospectively compare the clinical efficacy of simultaneous versus delayed timing of soft tissue augmentation by SCTG placement around single implants, by evaluating the peri-implant marginal bone level change and soft tissue change, so as to provide reference for the formulation of clinical treatment plan and the selection of the best operation time.

Soldiers operate in environments that are more likely to lead to oral trauma, risking poor dentition which can directly impact military readiness. Dental restoration can often be accomplished via dental implant insertion. Microbiome-associated complications that result in bone loss, including the micro-leakage of bacterial species proliferating in the dental implant internal cavity, frequently lead to implant failure. Reduction in implant bacterial load may result in a shift of the composition of the microbiome in favor of less pathogenic species, potentially improving dental implant success rates, reducing surgical revisions, and associated cost savings. This study aims to determine how disinfectant gel (hydrogen peroxide or chlorhexidine) insertion into dental implant internal cavities affects implant failure rates, bacterial load and microbiome composition.

Peri-implantitis is a high prevalence disease that affects Dental Implants, and can lead to the implant loss if untreated. This condition isn't really well known, and treatments can't provide predictable results. The aim of this study will be to establish a link between the Epstein Barr Virus and the Peri-implantitis, as suggested by recent studies.
