Aim The aim of this study was to assess the accuracy of periapical radiography in measuring peri‐implant bone levels. Materials and Methods Twenty‐five subjects with 46 implants in need of surgical treatment for peri‐implantitis were included in this cross‐sectional study. Prior to surgery, periapical radiographs were taken, a prediction of type of defect was made and radiographic peri‐implant bone levels ( R x BL ) were determined at the mesial and distal aspects. Intra‐operatively, the peri‐implant bone level ( S urg BL ) was assessed mesially, distally, buccally and orally and the type of defect was recorded. A paired t ‐test was applied to detect differences between inter‐proximal R x BL and Surg BL . ANOVA was used to compare Surg BL at different circumferential positions. Results The mean inter‐proximal Rx BL was 4.0 ± 2.2 mm and the mean inter‐proximal Surg BL was 5.3 ± 2.3 mm. The difference between Rx BL and Surg BL was statistically significant ( p = 0.014). There were no significant differences in Surg BL at the mesial, distal, buccal and oral aspects ( p > 0.05). Conclusions The intra‐operatively measured peri‐implant bone levels were more apical than the radiographic bone levels. The intra‐operatively assessed peri‐implant bone levels ( S urg BL ) were similar at all the circumferential positions around the implant.
