Brief Summary
One critical element regarded to successfully resolve peri-implantitis is to efficiently decontaminate the contaminated implant surface. Mechanical, pharmacological and chemical strategies have been proposed to eliminate bacterial plaque and remnants from the implant surface. However, evidence has not demonstrated superiority of a given detoxification agent/strategy. Recently, the electrolytic approach has been indicated for the surgical detoxification in the management of peri-implantitis. For the electrolytic approach (EA) the implant has to be loaded negatively with a voltage and a maximum current of 600 mA. This is achieved by a device (GS1000, GalvoSurge Dental AG, Widnau, Switzerland) providing the voltage and pumping a sodium formiate solution through a spray-head, which has to be pressed into the implant by finger pressure to achieve an electrical contact. Another critical aspect in the management of peri-implantitis is related to the esthetic sequelae associated with disease resolution. Sanz-Martin et al. in a systematic review demonstrated that reconstructive therapy is less prone to exhibit mucosal recession when compared to resective therapy. Nonetheless, it seems to be unavoidable no matter the surgical intervention. Aiming at attenuating these changes, Schwarz et al. noted that the adjunctive use of connective tissue grafts may enhance the height of the mucosal level, which in turn may impact upon the esthetic outcome. Therefore, the research question is the following: What is the clinical, radiographic and 3D volumetric effectiveness of dermal matrix to improve the outcome of reconstructive therapy of peri-implantitis-related bone defects? The study is to be performed in two centers: Center of Implantology, Oral and Maxillofacial in Badajoz (Spain) and Clinical PerioCentrum Ortiz-Vigon in Bilbao (Spain)
