Peri-implantitis causing bone loss, exposition of dental implant, and biofilm formation. A Schematic illustration of bone loss around implant (red arrow). B Red arrow correspond to implant exposition for bacterial colonization, after bone loss. The area around implant resulting from bone loss is filled by complex biofilm community (green) formed by diversity bacterial, fungal, and virous species, distributed according to nutritional and biochemical needs. Bacterial species described in higher proportion of peri-implantitis are responsible for initiation of community formation and, in an opportunistic way in the infectious process, other species of bacteria, fungi and viruses are also part of this biofilm complex
