INTRODUCTIONDental implant is a highly anticipated therapy with widespread use. He has become embedded within a large number of dental practices around the world and has grown and evolved rapidly, driven by consumer demand for immediate fixed tooth replacements (1).However, various cases of implant complications have been reported, in particular peri-implantitis. It is featured by progressive bone loss that results from the inflammation evoked by the colonization of the peri-implant sulcus by pathogenic bacteria (2). The diagnosisis based on composite criteria, including radiographic and clinical features such as progressive bone loss (plus/minus 0.5 mm), increased probing pocket depth, erythema, and bleeding on gentle probing with or without suppuration (3).Various surgical and nonsurgical modalities have been proposed in order to resolve soft tissue inflammation and to halt progressive bone loss. It was noted that when implants with ≥50% of bone loss, the most reasonable therapy to eradicate the disease is to remove the implant.
