Abstract
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 (RxBL) were determined at the mesial and distal aspects. Intra-operatively, the peri-implant bone level (SurgBL) 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 RxBL and SurgBL. ANOVA was used to compare SurgBL at different circumferential positions. RESULTS: The mean inter-proximal RxBL was 4.0 ± 2.2 mm and the mean inter-proximal SurgBL was 5.3 ± 2.3 mm. The difference between RxBL and SurgBL was statistically significant (p = 0.014). There were no significant differences in SurgBL 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 (SurgBL) were similar at all the circumferential positions around the implant.
