“…Using ICCs, it was found that the accuracy of the linear measurements versus the gold standard was excellent for both devices (Table 2), although all linear measurements were underestimated by the examiners, corroborating the results of several studies described in the literature 4679101123. In addition, thin bony structures of less than 0.5 mm in size are not relevant in actual clinical practice, which compromises the reliability of the CBCT images310 once areas without bone are considered.…”

“…In addition, thin bony structures of less than 0.5 mm in size are not relevant in actual clinical practice, which compromises the reliability of the CBCT images310 once areas without bone are considered. This lack of precision leading to values that underestimate the real measurements may be explained by the partial volume effect 24252627.…”

PurposeThis study was performed to investigate the intra- and inter-observer variability in linear measurements with axial images obtained by PreXion (PreXion Inc., San Mateo, USA) and i-CAT (Imaging Sciences International, Xoran Technologies Inc., Hatfield, USA) CBCT scanners, with different voxel sizes.Materials and MethodsA cylindrical object made from nylon with radiopaque markers (phantom) was scanned by i-CAT and PreXion 3D devices. For each axial image, measurements were taken twice in the horizontal (distance A-B) and vertical (distance C-D) directions, randomly, with a one-week interval between measurements, by four oral radiologists with five years or more experience in the use of these measuring tools.ResultsAll of the obtained linear measurements had lower values than those of the phantom. The statistical analysis showed high intra- and inter-observer reliability (p=0.297). Compared to the real measurements, the measurements obtained using the i-CAT device and PreXion tomography, on average, revealed absolute errors ranging from 0.22 to 0.59 mm and from 0.23 to 0.63 mm, respectively.ConclusionIt can be concluded that both scanners are accurate, although the linear measurements are underestimations, with no significant differences between the evaluators.

“…Finally, Thönissen et al. () supported the need for improved CBCT image resolution for anatomic structures less than 0.5 mm in width. However, the possibility of using smaller FOVs and smaller voxel sizes to increase image resolution and to limit the radiation dose should be considered in the 3D volumetric analysis of alveolar sockets.…”

Alveolar sockets with extensive buccal bone deficiencies undergo significant three-dimensional volumetric alterations following natural healing. The immediate application of a slow-resorbing xenograft with a covering collagen membrane seems to be effective in improving alveolar ridge shape and dimensions, thus potentially reducing the need for adjunctive regenerative procedures at the time of implant placement.

“…It is stated that mandibular fractures are often associated with other jaw fractures . Thonissen et al . found that the overall specificity for detecting thin bony structures of the human jaw in CBCT scans is low at 13.89%, and this may be a result of differences between dose and high‐resolution protocol .…”
