“…Cone-beam computed tomography correlates well with histomorphometrical measurements of peri-implant bone (Ritter et al, 2014). It has been shown that the precision and reproducibility of alveolar bone-level measurements are high for various voxel sizes (Menezes, Janson, da Silveira Massaro, Cambiaghi, & Garib, 2016). High-definition cone-beam computed tomography has been described as an accurate technique for millimeter-range measurements of bone structures in the direct vicinity of titanium implants (Gröbe et al, 2017).…”

Objectives To investigate the in vitro diagnostic accuracy of low‐dose cone‐beam computed tomography (LD‐CBCT) for the detection, classification, and measurement of peri‐implant bone lesions. Material and methods Titanium dental implants with all‐ceramic single crowns (n = 24) were inserted into bovine bone. At twelve implants, four types of peri‐implant bone lesions were created. Radiographic imaging was performed using three techniques: LD‐CBCT, high‐definition CBCT (HD‐CBCT), and intraoral radiography (IR). The datasets were presented twice to four observers in a random order. Diagnostic accuracy was measured by calculating sensitivity and specificity, and analyzed using the McNemar's test at a significance level of 0.05. Absolute agreement between the defect sizes was assessed by means of intraclass correlation coefficients (ICC). Results For all three techniques, diagnostic accuracy and reliability for the detection of defects were almost perfect. The following order was found for classification of the different defect types (sensitivity/specificity): HD‐CBCT (0.96/0.99) > LD‐CBCT (0.93/0.98) > IR (0.71/0.95). No significant difference was found between the two CBCT techniques. Their performance was superior to that of IR. With regard to absolute agreement of defect size, LD‐CBCT agreement with HD‐CBCT (ICC, 95% confidence interval) was slight for defect depth (0.342, 0.181–0.625) and substantial for defect width (0.911, 0.775–0.963). Conclusion Intraoral radiography is useful for detecting peri‐implant bone lesions. LD‐CBCT provides additional information regarding the geometry of defects. The even higher diagnostic accuracy of the HD‐CBCT protocol tested needs to be carefully weighed against its radiation dose, which is 14 times higher than that of LD‐CBCT.

“…25 It is well known that the smaller the voxel size, the richer the imaging details. [16][17][18]25,26 Menezes et al 26 suggested that there was adequate precision for crestal bone measurements only when the voxel size was 0.3 mm or smaller. Also it is well known that the smaller the voxel size, the higher the ionizing radiation.…”

Objectives: To test the null hypothesis that there is no difference in bone dehiscence formation before and after orthodontic tooth movement through an atrophic alveolar ridge. Material and Methods: This longitudinal retrospective study evaluated pretreatment and posttreatment cone-beam computed tomography imaging of 15 adult patients. Twenty-five teeth were moved through the atrophic alveolar bone, whereas 25 teeth not subjected to translational movement were considered controls. The distances between the cementoenamel junction and the alveolar bone crest were assessed at the mesial, distal, buccal, and lingual surfaces of all of these teeth. Data were compared using the Wilcoxon test. The Spearman correlation test and multivariate linear regression analysis were also performed. Results: In general, crestal bone height was reduced around 0.5 mm in all groups in every direction. Median buccal dehiscence increased significantly (þ2.25 mm) (P , .05) in teeth moved through the atrophic ridge. Control teeth also had buccal crest loss (þ0.83 mm), but this was not statistically different from that of the experimental teeth. Lingual dehiscence increased significantly for the experimental (þ0.17 mm) and control (þ0.65 mm) groups. Mesial bone height decreased more in the control group (-0.44mm) than in the experimental group (-0.14mm). There was moderate correlation between amount of tooth movement and alveolar bone loss. Conclusions: The null hypothesis was rejected as dehiscence increased after tooth movement through an atrophic alveolar ridge, mainly in the buccal plate. (Angle Orthod. 2020;90:321-329.)

“…Although this setting may impact on the quality of the images, it was selected to obtain the superimposition of CBCT images based on craniofacial anatomic landmarks(Alsufyani et al, 2014). Nevertheless, as regards image resolution,Menezes, Janson, da Silveira Massaro, Cambiaghi, and Garib (2016) found comparable accuracy in linear measurements of alveolar bone crest levels on dried human mandibles comparing to anatomic measurements for voxel dimensions of 0.2, 0.3, and 0.4 mm. Similar results were obtained by de Rezende Barbosa, Wood, Pimenta, Maria de Almeida, and Tyndall (2016) in the calculation of jaw cleft volume and byMaret et al (2012) for tooth volumetric measurements (using micro-CBCT) using different FOVs and voxel sizes Kamburoğlu et al (2015).…”

Three‐dimensional analysis of bone remodeling following ridge augmentation of compromised extraction sockets in periodontitis patients: A randomized controlled study

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.
