Purpose
This is a pilot study which aims to evaluate the accuracy of cone-beam computed tomography (CBCT) to assess the configuration and extent of ligature-induced peri-implantitis defects.
Materials and methods
Radiographic evaluation of advanced ligature-induced peri-implantitis defects (n = 9) in canine was performed using CBCT (central cross-sections) and compared with the corresponding histomorphometrical measurements of the respective site serving as a validation method. Deviations were calculated for the supracrestal (SC), and intrabony (IC) defect components, as well as defect width (DW) assessed at both vestibular (v) and oral (o) aspects.
Results
Mean differences between CBCT and histological analyses were −0.53 ± 1.48 mm (SC), +0.49 ± 1.18 mm (IC), and +0.18 ± 0.54 mm (DW) at vestibular aspects, and −0.13 ± 0.44 mm (SC), −0.05 ± 0.62 mm (IC), and +0.15 ± 0.48 mm (DW) at the oral aspects (P > 0.05; paired t test, respectively).
Conclusion
CBCT may represent an accurate diagnostic tool to estimate the histological extent of advanced peri-implantitis defects.
