| research 06 implants 1 2016 Basic evaluation of an antimicrobial gel for peri-implantitis treatment Authors: Dr Georg Bach & Christian Müller, Germany Figs. 1a–e: Peri-implant defect— Simulated model: Crater-shaped defects were prepared in plastic jaws typically used for insertion exercises. Brand-new implants were placed in the middle of these defects in a way that at least three threads were ex- posed (a–c). The jaws were divided into smaller units (d & e) and autoclaved before conducting phase II examinations (bacterial cultivation —Perisolv application—Microbio- logical diagnostics etc.) in order to allow better fit into the furnace as well as in vials containing culture medium. Introduction Early complications, which have been regarded as the major dread in the initial phase of oral im- plantology, have become a rare phenomenon for a fairly long time. Reasons for this positive develop- ment can be found in significant improvements of the implant surfaces, improved insertion tech- niques as well as in new ways to improve the pro- spective implant site. Nevertheless, with the enormously increased number of inserted implants, a significant in- crease of late complications has meanwhile been recorded.1,4,12 These complications typically man- ifest themselves many years after installation of the superstructure by means of peri-implant bone loss around artificial tooth pillars.17,20,21,25 Often associated with an insufficient or declining oral hygiene of the patient, these peri-implant lesions lead to the loss of the artificial tooth pillar and the corresponding suprastructure in case they are not treated.5,11,13,14 Many authors regard the development of peri-implantitis therapies as one of the current key challenges of implantol- ogy.15,18–20,26 Cleaning and disinfection of the exposed im- plant areas represents an undeniable requirement. For the latter step the term "decontamination" has been generally established.3,16 For decontamina- tion, various methods are indicated for their ­suitability.3,6,8,16,21-24 The aim of this study was to evaluate the suitability of using an antimicrobial gel for peri-implantitis treatment in an in-vitro experiment.
