ObjectivesWe investigated and compared the errors generated by multislice computed tomography (MSCT), cone-beam computed tomography (CBCT), and digital dental casts when used to provide digital data about dental structures.MethodsTen A20 skull models were scanned with MSCT and CBCT, and dental plaster cast models were optically scanned in three dimensions. The maxillary dental area was then compared. The distance between the three-dimensional scan data of the skull and each set of digital… Expand
Accuracy and eligibility of CBCT to digitize dental plaster casts
Most CBCT systems enabled digitization of plaster casts, and accuracy was found sufficient for digital planning and storage purposes, but within the limits of the study, accuracy appeared to be sufficient fordigital planning and forensic purposes. Expand

Dental image replacement on cone beam computed tomography with three-dimensional optical scanning of a dental cast, occlusal bite, or bite tray impression.
Although producing a dental cast can be laborious, the study results indicate that it is the preferred method and an occlusal bite is recommended when bite impression materials are used. Expand
Reproducibility and accuracy of linear measurements on dental models derived from cone-beam computed tomography compared with digital dental casts.
With the CBCT settings used in this study, measurements made directly on CBCT images and Anatomodels are not as accurate as measurements on Digimodels, and the random errors were relatively large compared with corresponding measurements reported in the literature, and might be clinically important.

Fusion of computed tomography data and optical 3D images of the dentition for streak artefact correction in the simulation of orthognathic surgery.
The accuracy of the fusion of 3D CT surface data and optical 3D imaging is significantly reduced by metal artefacts, however, it seems appropriate for virtual orthognathic surgery simulation, as post-operative orthodontics are performed frequently. Expand
Impact of the number of registration points for replacement of three-dimensional computed tomography images in dental areas using three-dimensional light-scanned images of dental models
Investigating the accuracy and reliability of registration methods for replacing dental areas of three-dimensional computed tomography images with 3D light-scanned dental images using tooth cusp tips and the occlusal surface found surface-based image registration giving less error than reference point- based image registration with dental cusp Tips.

A comparative study of the accuracy and reliability of multidetector computed tomography and cone beam computed tomography in the assessment of dental implant site dimensions.
Investigation of linear measurements of edentulous ridges recorded from 16-row multidetector CT images and cone beam CT (CBCT) images acquired using a flat panel detector with a large field of view found CBCT measurements were significantly more accurate than those of MDCT. Expand
A comparison between dental measurements taken from CBCT models and those taken from a digital method.
CBCT digital models are as accurate and reliable as the digital models obtained from plaster casts, and the differences existing between both methods are clinically acceptable. Expand

CBCT renders anatomic measures reliably and is an appropriate tool for linear measurements, but even the 0.125-mm voxel protocol does not depict the thin buccal alveolar bone covering reliably, and there is a risk of overestimating fenestrations and dehiscences. Expand
Comparison of space analysis evaluations with digital models and plaster dental casts.
The accuracy of the software for space analysis evaluation on digital models is clinically acceptable and reproducible when compared with traditional plaster study model analyses. Expand
A comparative evaluation of Cone Beam Computed Tomography (CBCT) and Multi-Slice CT (MSCT). Part II: On 3D model accuracy.
The results show that the accuracy of CBCT 3D surface model reconstructions is somewhat lower but acceptable comparing to MSCT from the gold standard. Expand
Comparative study of reproducibility and accuracy in measuring mesiodistal tooth sizes using three different methods: 2D digital, 3D CBCT, and 3D CBCT segmented
A 3D CBCT method has been developed that presented good accuracy for the intercanine width, intermolar width, and arch length, but not for the mesiodistal tooth sizes. Expand
