Abstract：
:Retrograde (or apical/periapical) peri-implantitis (RPI) presents with radiographic signs of bone loss at the periapical area of endosteal implants and may also present with clinical signs of abscess formation or a sinus tract traceable to the implant periapex. The lesion may form days up to several years after the initial implant placement. In contrast to marginal peri-implantitis, which has a prevalence of 19.83%, RPI may be underreported because many clinicians are currently not aware of this type of lesion. The etiology, although not fully understood, may be attributed to endodontic infection of an adjacent tooth or residual microorganisms present after the extraction of an infected tooth at the implant site. There are several treatment modalities available for the management of RPI. Nonsurgical root canal treatment may be an option if the implant RPI etiology is suspected to be related to an adjacent endodontically involved tooth. In a previous report, surgical treatment modalities to correct RPI were described. This current case series presents 2 cases of RPI in which nonsurgical treatment of the necrotic adjacent teeth resulted in full radiographic and clinical resolution of the adjacent apical peri-implant lesions with 18-month and 2-year follow-ups, respectively. RPI may be prevented by evaluating the endodontic status of natural teeth adjacent to the implants and by addressing endodontic infections near the implant sites. Certain types of implant RPI may successfully be resolved nonsurgically by addressing adjacent endodontic infections as shown by this case series.
