Accuracy of linear measurements on CBCT images related to presurgical implant treatment planning: A systematic review

“…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., ).…”

“…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., ).…”

“…The mean difference was used in 12 studies (Alkan et al., ; Eachempati et al., ; Freire‐Maia et al., ; Gerlach et al., ; Loubele et al., ; Luangchana et al., ; Luk et al., ; Pena de Andrade et al., ; Santana et al., ; Torres et al., ; Vasconcelos et al., ; Veyre‐Goulet et al., ), two studies presented the mean absolute difference (Ganguly et al., ; Gerlach et al., ), and one study also presented the mean relative difference as a percentage (Gerlach et al., ).…”

“…No clear trend in measurement error is apparent as authors report both overestimation (Al‐Ekrish, ; Al‐Ekrish & Ekram, ; Al‐Ekrish et al., ; Freire‐Maia et al., ; Gerlach et al., , ; Kobayashi et al., ; Loubele et al., ; Luk et al., ; Pena de Andrade et al., ; Vasconcelos et al., ; Waltrick et al., ) and underestimation (Alkan et al., ; Eachempati et al., ; Freire‐Maia et al., ; Ganguly et al., ; Luangchana et al., ; Pena de Andrade et al., ; Santana et al., ; Sheikhi et al., ; Torres et al., ; Vasconcelos et al., ; Veyre‐Goulet et al., ; Waltrick et al., ) between CBCT and the “gold standard” measurements.…”
