Objectives
The aim of this study was to assess the accuracy of detecting and measuring buccal
bone thickness (BBT) adjacent to titanium implants in cone beam computed tomography
(CBCT) images.
Study Design
Titanium implants (1, 2, or 3), abutments, and metal–ceramic crowns were inserted
into 40 bone blocks with various BBTs. CBCT images were acquired in various settings:
Voxel sizes (0.2 and 0.13 mm) and reconstruction section thicknesses (2.0 and 5.0
mm) were assessed by 3 examiners. True BBT was measured in digital photographs of
the bone blocks. Buccal bone detection was evaluated by sensitivity and specificity.
BBT was evaluated by 1-way analysis of variance (ANOVA) between the true and the CBCT
measurements and by calculating the difference between the true measurement and the
CBCT measurement (Di-BBT).
Results
Detection of buccal bone exhibited high sensitivity (0.86–1) and low specificity (0.14–1).
More implants in the field of view, large voxel size, and thick image reconstruction
sections had a negative impact on buccal bone detection. ANOVA showed statistically
significantly larger BBT for the CBCT measurements in all settings (1.07–1.21 mm)
compared with the true measurements (0.85 mm). Di-BBT was mostly within 0.5 mm.
Conclusions
BBT adjacent to titanium implants is overestimated when evaluated on CBCT cross-sectional
images.
