“…Of those, two were clinical (Eachempati et al., ; Luk, Pow, Li & Chow, ) and 20 ex vivo investigations. The ex vivo studies included 14 studies on dry jaws/skulls (Al‐Ekrish, ; Al‐Ekrish & Ekram, ; Al‐Ekrish, Ekram, Al Faleh, Alkhader & Al‐Sadhan, ; Alkan, Aral, Aral, Acer & Şişman, ; Freire‐Maia et al., ; Kamburoglu, Kilic, Ozen & Yuksel, ; Luangchana, Pornprasertsuk‐Damrongsri, Kiattavorncharoen & Jirajariyavej, ; Neves, Vasconcelos, Campos, Haiter‐Neto & Freitas, ; Pena de Andrade, Valerio, de Oliveira Monteiro, de Carvalho Machado & Manzi, ; Sheikhi, Dakhil‐Alian & Bahreinian, ; Torres, Campos, Segundo, Navarro & Crusoe‐Rebello, ; Vasconcelos, Neves, Moraes & Freitas, ; Veyre‐Goulet, Fortin & Thierry, ; Waltrick et al., ) and six cadaver studies (Ganguly et al., ; Gerlach et al., , ; Kobayashi, Shimoda, Nakagawa & Yamamoto, ; Loubele et al., ; Santana et al., ).…”

“…The two included clinical studies assessed edentulous sites of patients prior to dental implant treatment (Eachempati et al., ; Luk et al., ). The majority of the selected studies used dry human mandibles as the sample (Al‐Ekrish, ; Alkan et al., ; Freire‐Maia et al., ; Kamburoglu et al., ; Kobayashi et al., ; Neves et al., ; Pena de Andrade et al., ; Sheikhi et al., ; Torres et al., ; Vasconcelos et al., ; Waltrick et al., ). Two studies used both the maxilla and mandible of dry skulls (Abboud et al., ; Al‐Ekrish & Ekram, ; Luangchana et al., ), and one study used only three dry maxillae (Veyre‐Goulet et al., ).…”

“…Seven of the ex vivo studies placed the dry jaws/skulls in a container with water to simulate the effects of soft tissue for CBCT imaging (Alkan et al., ; Freire‐Maia et al., ; Neves et al., ; Sheikhi et al., ; Torres et al., ; Vasconcelos et al., ; Veyre‐Goulet et al., ), while Luangchana et al. covered the jaws entirely in acrylic resin for that purpose (Luangchana et al., ).…”

“…Of the authors that aimed solely to evaluate the accuracy of CBCT, some used one single machine and fixed acquisition parameters (Gerlach et al., , ; Kamburoglu et al., ; Kobayashi et al., ; Veyre‐Goulet et al., ), while others evaluated the effect of different scan parameters (Al‐Ekrish, ; Ganguly et al., ; Neves et al., ; Torres et al., ; Waltrick et al., ), different reconstruction software (Vasconcelos et al., ), or different monitors (Al‐Ekrish et al., ) on linear accuracy. Furthermore, in several studies the authors’ primary objective was to compare the accuracy of CBCT with other radiographic or clinical diagnostic tests (Al‐Ekrish & Ekram, ; Alkan et al., ; Eachempati et al., ; Freire‐Maia et al., ; Loubele et al., ; Luangchana et al., ; Luk et al., ; Pena de Andrade et al., ; Santana et al., ; Sheikhi et al., ).…”

Objective: The aim of this systematic review was to identify, review, analyze, and summarize available evidence on the accuracy of linear measurements when using maxillofacial cone beam computed tomography (CBCT) specifically in the field of implant dentistry. Material and methods:The search was undertaken in April 2017 in the National Library of Medicine database (Medline) through its online site (PubMed), followed by searches in the Cochrane, EMBASE, ScienceDirect, and ProQuest Dissertation and Thesis databases. The main inclusion criterion for studies was that linear CBCT measurements were performed for quantitative assessment (e.g., height, width) of the alveolar bone at edentulous sites or measuring distances from anatomical structures related to implant dentistry. The studies should compare these values to clinical data (humans) or ex vivo and/or experimental (animal) findings from a "gold standard." Results:The initial search yielded 2,516 titles. In total, 22 studies were included in the final analysis. Of those, two were clinical and 20 ex vivo investigations. The major findings of the review indicate that CBCT provides cross-sectional images that demonstrate high accuracy and reliability for bony linear measurements on crosssectional images related to implant treatment. A wide range of error has been reported when performing linear measurements on CBCT images, with both overand underestimation of dimensions in comparison with a gold standard. A voxel size of 0.3 to 0.4 mm is adequate to provide CBCT images of acceptable diagnostic quality for implant treatment planning.Conclusions: CBCT can be considered as an appropriate diagnostic tool for 3D preoperative planning. Nevertheless, a 2 mm safety margin to adjacent anatomic structures should be considered when using CBCT. In clinical practice, the measurement accuracy and reliability of linear measurements on CBCT images are most likely reduced through factors such as patient motion, metallic artefacts, device-specific exposure parameters, the software used, and manual vs. automated procedures.

Purpose The shape and position of the inferior alveolar canal (IAC) are analyzed to effectively reduce the risk of iatrogenic injury based on cone‐beam computer tomography (CBCT). To assist dental clinicians to make better use of the IAC information, we propose an IAC segmentation method based on CBCT images. Methods In this paper, CBCT images are first preprocessed by the Hounsfield unit values clipping and gray normalization. Secondly, based on the multi‐plane reconstruction (MPR) and curved surface reconstruction, the curved MPR image sets are generated by the smooth dental arch curve with a sampling distance of 1.00 pixels. Then, the K‐means clustering algorithm is used to cluster the texture parameters of the gray level‐gradient co‐occurrence matrix enhanced by the gradient directions to improve the image contrast of the IAC. Finally, the IAC edges are roughly segmented by the 2D line‐tracking method, and smoothed by the fourth‐order polynomial to obtain the final segmentation result. Results Twenty‐one real clinical dental CBCT datasets were used to test the proposed method. The manual segmentation results of two specialized dental clinicians were used as quantitative evaluation criteria. The dice similarity index (DSI), average symmetric surface distance (ASSD), and mean curve distance (MCD) of the left IAC are 0.93 (SD = 0.01), 0.16 mm (SD = 0.05 mm), and 1.59 mm (SD = 0.25 mm), respectively; the DSI, ASSD, and MCD of the right IAC are 0.93 (SD = 0.02), 0.16 mm (SD = 0.05 mm), and 1.60 mm (SD = 0.30 mm), respectively. Conclusions The proposed method provides an effective image enhancement and segmentation solution to analyze the shape and position of the IAC. Experimental results show that the relationships between the IAC and other structures can be accurately reflected in the panoramic images without superimposition and geometric distortion, and the smooth edges of the IAC can be segmented.
