Article: [The reliability and accuracy of the digital models reconstructed by cone-beam computed tomography].[show abstract] [hide abstract]
ABSTRACT: To evaluate the reliability of the digital models scanned by cone-beam computed tomography (CBCT). Forty plaster models of patients with orthodontic treatment were selected. These plaster models were scanned and measured by 3DX cone beam CT, compared with manual measurement via concordance correlation coefficient (CCC) and mean difference (MD). The CCC of all the measurement was from 0.847 to 0.993. The value of MD of all the measurement was below 0.25mm except CFF6, PWF5 and PWF6, which was 0.34mm, 0.63mm and 1.49mm, respectively. The reliability and accuracy of the digital models scanned by cone-beam CT is very high. The accuracy of measurement of the dental cusp is the highest, the dental fossa is the second, and the lowest point of palatal gingival is the third.Shanghai kou qiang yi xue = Shanghai journal of stomatology 10/2011; 20(5):512-6.
