Retrograde peri-implantitis (RPI) is defined as a clinically symptomatic periapical lesion. RPI is generally accompanied by symptoms of pain, tenderness, swelling and fistula. Several etiologic factors of RPI were possible, residual bacteria would be the main cause of RPI. Various treatment modalities have been introduced: debridement only or a combination of debridement with the grafting material accompanied by a detoxification of the infected implant surfaces, apicoectomy and so on. Although the definitive management methods remain undefined, many favorable clinical results of a treatment of RPI have been published. This case report introduces the 7-year long-term clinical result of the application the principle: implant surface detoxification using saline and chlorhexidine and guided bone regeneration with bone graft material and barrier membrane. If the implant was not mobile, it would be possible to treat RPI according to surgical approach and good results will be maintained over long term.
