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. }
