The validity of different display monitors in the assessment of dental implant site dimensions in cone beam computed tomography images

Abstract

No differences in the reliability or accuracy of measurements of implant site dimensions were obtained using color LCD monitors with different contrast resolution capabilities.

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., ).…”

“…For many studies, the stated objectives were often at variance from the methodology and results presented. 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., ).…”

“…() used a combination of an analogue and a digital caliper on cadaver dissections to establish to extension of the anterior loop of the mental branch relative to the mental foramen. The accuracy of these measuring instruments was specified in only seven studies: Three studies described a 0.01 mm accuracy of the caliper used (Loubele et al., ; Sheikhi et al., ; Waltrick et al., ) and four described an accuracy of 0.02 mm (Al‐Ekrish, ; Al‐Ekrish & Ekram, ; Al‐Ekrish et al., ; Luangchana et al., ). The two studies by Gerlach et al.…”

“…The correlation between CBCT and the reference standard used was presented in six of the included studies (Alkan et al., ; Eachempati et al., ; Kamburoglu et al., ; Luangchana et al., ; Neves et al., ; Waltrick et al., ), and two assessed agreement (Eachempati et al., ; Sheikhi et al., ). The mean measurement error in millimeters between the two values was calculated in two studies (Kobayashi et al., ; Sheikhi et al., ), one study presented the absolute error of the measurements in millimeters (Luangchana et al., ), four studies evaluated the mean absolute error in millimeters (Al‐Ekrish, ; Al‐Ekrish & Ekram, ; Al‐Ekrish et al., ; Waltrick et al., ), and three studies reported on the absolute percentage error (Kobayashi et al., ; Luangchana et al., ; Torres et al., ).…”

“…In studies that assessed absolute error (millimeters) between the two measurements, most authors reported low values ranging from 0.04 mm (Sheikhi et al., ) to 0.68 mm (Al‐Ekrish et al., ) with the exception of Luangchana et al. (), who reported errors of 1.14 to 1.27 mm for the maxilla (Luangchana et al., ).…”
