Filter by:The aim of this study was to evaluate the effects of a dentifrice containing 0.3% triclosan on periodontal and peri-implant parameters in patients, with or without periodontitis, treated for peri-implantitis and that were enrolled in a maintenance phase for two years.
The aim of this randomized controlled study is to evaluate the outcome of surgical treatment of peri-implantitis with and without the use of a bone substitute graft covered by a collagen membrane. There will be a follow up period of 12 months. Outcome measures will include assessments of inflammation, probing depth, recession, radiological parameters and PROMs.
The effect of the hyaluronic acid treatment on peri-implantitis has not been tested. The aim was to analyze the effect of a hyaluronic acid-containing gel on the clinical variables and the expression of biochemical inflammatory markers in the crevicular fluid of implants receiving perimplantitis treatment.
The aim of this study was to evaluate the influence of a triclosan-containing toothpaste in the profile of osteo-immunoinflammatory mediators in the peri-implant crevicular fluid (PICF) and in the clinical parameters during the progression of experimental peri-implant mucositis.
The work hyposesis is based on the application of a chlorhexidine gel against the non-application on the healing abutments in patients who have received a submerged titanium implant to check its effect on healing and prevention of bacterial plaque accumulation during a period of 1 month.
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.
Peri-implantitis represents a major biological complication of implant dentistry with reported prevalence of up to 47% of implants. The disease is characterized by inflammatory response to the biofilm inhabiting the implant surface. To treat this inflammatory disease, surgical and non-surgical therapies have been proposed, all of which entail biofilm removal through implant surface decontamination. Systematic review of various surface decontamination protocols has failed to demonstrate superiority of any of the protocols. One possible explanation is that most studies have examined decontamination of implant surfaces following experimentally-induced peri-implantitis, where implant surfaces lack the tenacious mineralized biofilm often found in clinical peri-implantitis and are therefore easily decontaminated. The investigators have hypothesized that control of inflammation and repair of pathologically damaged peri-implant tissues requires a comprehensive mechanical plus chemical surface decontamination therapy. The aims of this study are to 1) determine the most effective surface decontamination protocol that can lead to control of peri-implant inflammation and 2) delineate the microbial and immunological mediators that are associated with the changes in peri-implant inflammation. The investigators propose to compare conventional implant surface contamination techniques to a comprehensive mechanical plus chemical protocol. This randomized controlled clinical trial seeks to enroll 68 participants with at least one implant diagnosed with moderate to severe peri-implantitis. Pre-op parameters to be assessed include: probing pocket depth, bleeding on probing, suppuration, plaque index, marginal inflammation, recession, clinical attachment level, inflammatory biomarkers and microbial sampling, and digital intra-oral peri-apical radiograph. Subjects will be randomly assigned to one of the four surgical debridement intervention groups: (A) gauzes soaked in sterile saline and chlorhexidine; (B) Titanium brush; (C) Air power abrasion; (D) comprehensive surface decontamination, including titanium brush, air powder abrasion and surface etching with 9.6% hydrofluoric acid gel. At 3-months post-operative, the initial clinical assessment will be repeated. The clinical examination will be used to analyze the efficacy of each treatment in controlling peri-implant mucosal inflammation. The ultimate objective of this research is not only to identify an effective method for control of peri-implant inflammation, but also to lay the foundation to detect biomarkers of peri-implantitis that can potentially be helpful in future studies as risk factors of this disease.
The American Association of Oral and Maxillofacial Surgeons estimated that 69% of adults ages 35 to 44 have lost at least one permanent tooth. Dental implants have revolutionized dentistry by providing tooth-like replacement for missing teeth and a solution that is predictable with long-term success.. After the implant is placed, natural bacteria from the mouth can develop around implants just like around natural teeth. Studies have shown that bacterial contamination can cause peri-implantitis- gum disease or inflammation around the implant, eventually leading to bone loss. Removing bacteria from dental implant surfaces can prevent peri-implantitis, and surface debridement constitutes the basis of treatment of peri-implant disease. Typically, mechanical hand instrumentation using curettes to remove biofilm and calculus is the main basis for periodontal therapy. However, total debridement is difficult, and the hand tools may damage the surface of the implant and making it more plaque retentive. Studies have shown that mechanical non-surgical therapy alone is not sufficient to treat peri-implantitis. There is evidence that a dental laser may be an effective method to remove bacteria from implant surfaces, with less damage to the surface. One type of dental laser, Er:YAG, appears optimal for implant decontamination as the Er:YAG laser energy is primarily absorbed by water, resulting in vaporization of bacteria and minimal surface alterations on the implant surface.The aim of this study is to evaluate the efficiency of biofilm decontamination of Er:YAG laser compared to carbon fiber curette.
The project will evaluate the potential benefit of the use of bone replacement graft as an adjunct to surgical therapy of peri-implantitis. The project will be conducted as a two-armed randomized controlled clinical trial of 5-year duration in 7 clinical centers. 140 systemically healthy patients diagnosed with peri-implantitis will randomly assigned to be treated with or without bone replacement graft. Outcome measures include assessments of inflammation, probing depth, recession, radiological parameters and PROMs.
Evaluate clinically and microbiologically the effect of the oral probiotic Lactobacillus reuteri Prodentis (PerioBalance®, Sunstar, Switzerland) on implants with mucositis or periimplantitis, as a coadjuvant treatment of mechanical therapy.
