AB - The following report presents a very unusual case of a 50-year-old man with retrograde peri-implantitis
secondary to pericoronitis of a horizontal, incompletely impacted mandibular right third molar. A conebeam computed tomography scan revealed the presence of a radiolucency at the apex of the mobile implant
at the right first molar site, which was detected one month after implant placement. The case management
involved removal of the mobile implant and arrangement of a second implant surgery as well as extraction
of the impacted third molar. The lesion gradually resolved over a 1-year period. The implant remained stable
with no evidence of recurrence over a 4-year follow-up period.
