Filter by:A clinical trial comparing laser treatment and conventional mucosal flap surgery for treatment of peri-implantitis. The main aim of the study is to evaluate if treatment of peri-implantitis with a novel blue laser (445 nm) combined with scaling and root planning (SRP) is clinically comparable to conventional mucosal flap surgery in terms of pocket probing depth reduction.
Considering the frequent occurence of peri-implantitis and mucositis, a multiple of treatment alternatives have been proposed including non-surgical and surgical procedures. However, it seems that the most effective treatment remains prevention of these diseases. The aim of this study is to emphasize on mucositis and peri-implantitis prevention using an air abrasion device the Air-Flow Master Piezon® with erythritol and chlorhexidine powder in order to eliminate and / or disorganize the biofilm responsible for peri-implant mucosa inflammation.
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.
Implant placement may trigger bone trauma, which might result in 3-dimensional bone changes. While the process of peri-implant disease is not well understood, implant position within the bony structure might play a role. However, there is no data available on this regard.
The primary objective of this study is to compare the clinical outcomes of using Er: YAG laser along with bone graft and barrier membrane to conventional mechanical debridement also with bone graft and barrier membrane in the treatment of peri-implantitis infections.
