Filter by:This pilot study is an interventional clinical study on the supportive peri-implant treatment (SPiT) necessary to maintain/ improve the clinical conditions surrounding a dental implant following surgical treatment of peri-implantitis. The focus of this pilot, double arm, split-mouth, single centre, controlled, randomised clinical study is to examine the effect of short-term increased frequency of a SPiT-protocol.
Surgical treatment of peri-implantitis can be regenerative or resective, depending on defect configuration. The aim of resective therapy of peri-implantitis is to reduce the severity of soft tissue inflammation and stabilize crestal bone levels whilst reducing probing depths.This will be a multicenter randomized controlled trial in which two resective peri-implantitis protocols will be assessed. The aim of this trial is to compare a resective approach in the surgical treatment of peri-implantitis (decontamination performed with titanium brushes and sterile saline) with a resective approach combined with implantoplasty.
The study will aim to compare two modalities in the reconstructive treatment of peri-implantitis defects. More specifically, the control group will be a reconstructive approach (xenograft bone graft granules and collagen membrane, BioOss and BioGide, Geistlich, Wolhusen). The test group will be the same with the exception of an autologous sub-epithelial connective tissue palatal graft, sutured beneath the flap, which will be used in addition to grafting materials. Outcomes will include CAL, PD, MR, defect resolution, PI, BoP, SUPP, patient-reported outcome measures including an aesthetic self-evaluation.
The study aims to assess the efficacy of Calprotectin and cross-linked N-telopeptides of type I collagen levels in crevicular fluid as a biomarker in patients with peri-implantitis.
Objective: the objective of the present randomized clinical trial is to compare changes in radiographic peri-implant bone defect fill after regeneration of peri-implant intrabony defects with a submerged versus a non-submerged protocol. Material and Methods: this project is a randomized controlled clinical trial, double blind, with a parallel groups design. Thirty-six patients presenting with peri-implantitis subsidiary of regenerative treatment will be recruited. After subjects have been given informed consent, they will be randomized to test or control group. All patients will undergo a session of non-surgical peri-implantitis therapy consisting on prostheses removal and implant debridement with ultrasounds, curettes and air-abrasive under local anaesthesia. Patients in test group will have their prostheses removed and the mucosa surrounding the affected implants will be let heal covering the implants, while patients in control group will have their prostheses installed again after the non-surgical therapy. Six to eight weeks later, all subjects will undergo regenerative treatment with the use of a bone substitute, a collagen membrane and fixation pins, and in control group tissues will heal following the non-submerged protocol, meanwhile subjects in test group will undergo submerged healing. Six months later, subjects in test group will have their prostheses reconnected to the regenerated implants. All patients will undergo periodontal and peri-implant maintenance therapy every three months during follow-up. Radiographic assessment of vertical bone level changes (primary outcome), clinical status of peri-implant tissues, changes in soft tissues margin, patient related outcomes and adverse events will be assessed at 3, 6 and 12 months after peri-implantitis regenerative surgery.
The elimination of pathogenic microorganisms from the muco-gingival tissue and implant pockets system is one of the main aspects for success in the treatment of peri-implantitis. The purpose of this study is to conduct a blinded and randomized clinical trial to evaluate the effectiveness of photodynamic therapy in the treatment of peri-implantitis. Twenty implants with peri-implantitis will be selected. Implants will be randomly divided into two groups (n = 10), Group 1: control - conventional treatment and Group 2: conventional treatment and antimicrobial photodynamic therapy (aPDT). aPDT will be performed after the purse removal service in sites with pockets greater than or equal to 5 mm. The photosensitizer will be PapaMblue®, which will be deposited in the peri-implant pockets, with pre-irradiation time of 1 min. Next, the laser emitting a wavelength of 660 nm, with power of 100 mW, for 2 min, radiant exposure of 30 J/cm2 and power density of 250 mW/cm2 in the buccal and mesial regions will be applied. The distribution of the data within each group will be evaluated and the variances will be checked to choose a more appropriate statistical analysis. The sample calculation is based on the literature and the significance level of 5% will be adopted.
