Abstract Objective To evaluate the accuracy between the intra‐surgical and the peri‐apical radiographic measurements of bone loss at implant with peri‐implantitis. Materials and methods A total of 46 Brånemark implants in 24 patients with diagnosis of peri‐implantitis were included in the study. The amount of peri‐implant bone loss occurred at those implants was measured during peri‐implant surgery and compared to the radiographic bone loss measured by three independent examiners. Results The mean bone loss measured on radiographs underestimated the intra‐surgical bone loss at the correspondent sites (0.7 mm at the mesial and 0.6 mm at the distal sites); this underestimation was found to be a consistent finding in all the three examiners. Only 21% of the radiographic measurements corresponded to the clinical bone loss assessments, while an over‐ and underestimation within a range of ± 1–2 mm was recorded in 57% of the cases. There was a moderate positive linear correlation between the radiographic measurements and the clinical bone loss for mesial and distal sites ( r = range 0.58–0.65). The variability between the three examiners in the radiographic measurements was frequently on the range of ± 1–2 mm. Conclusion The radiographic measurements of bone loss at implant affected by peri‐implantitis often underestimated the clinical bone loss occurred at the implants. A difference of about ± 1–2 mm in the estimation of radiographic bone loss could be merely assigned as inter‐examiner different assessments.
