Baseline periapical radiograph (at one year of follow-up) from a 59 years old female patient with no history of periodontitis who was a non-smoker, rehabilitated with a three-unit implant-supported rehabilitation [three implants of 7 mm in length, positions #44–#46; Risk points = −1 due to adjacent implants or teeth present) restored using metal–ceramic material (Risk points = 2). Bacterial plaque (Risk points = 2) and bleeding (Risk point = 2) were present, and the bone level was located on the implants’ coronal third. Due to the presence of bacterial plaque and the presence of adjacent implants or teeth, 3 risk points were added. A total score of 8 points was registered for this patient which corresponded to the very high-risk group.
