Accuracy of Bolton analysis measured in laser scanned digital models compared with plaster models (gold standard) and cone-beam computer tomography images.
OBJECTIVE The aim of this study was to compare the accuracy of Bolton analysis obtained from digital models scanned with the Ortho Insight three-dimensional (3D) laser scanner system to those obtained from cone-beam computed tomography (CBCT) images and traditional plaster models. METHODS CBCT scans and plaster models were obtained from 50 patients. Plaster models were scanned using the Ortho...
متن کاملVolumetric accuracy of cone-beam computed tomography
PURPOSE This study was performed to investigate the influence of object shape and distance from the center of the image on the volumetric accuracy of cone-beam computed tomography (CBCT) scans, according to different parameters of tube voltage and current. MATERIALS AND METHODS Four geometric objects (cylinder, cube, pyramid, and hexagon) with predefined dimensions were fabricated. The object...
متن کاملAccuracy and reliability of stitched cone-beam computed tomography images
PURPOSE This study was performed to evaluate the linear distance accuracy and reliability of stitched small field of view (FOV) cone-beam computed tomography (CBCT) reconstructed images for the fabrication of implant surgical guides. MATERIALS AND METHODS Three gutta percha points were fixed on the inferior border of a cadaveric mandible to serve as control reference points. Ten additional gu...
متن کاملAccuracy of craniofacial measurements: computed tomography and three-dimensional computed tomography compared with stereolithographic models.
In a retrospective study, distance measurements of nine children with craniofacial malformation were analyzed. The accuracy of measurements was compared when measured on a workstation using a 16-slice multidetector spiral computed tomography and on a stereolithographic model. Three different methods of defining distances were investigated: 1) on the stereolithographic plastic models, 14 distanc...
متن کاملA Comparative Evaluation of Mixed Dentition Analysis on Reliability of Cone Beam Computed Tomography Image Compared to Plaster Model
AIMS AND OBJECTIVE The aim of the study was to evaluate the reliability of cone beam computed tomography (CBCT) obtained image over plaster model for the assessment of mixed dentition analysis. MATERIALS AND METHODS Thirty CBCT-derived images and thirty plaster models were derived from the dental archives, and Moyer's and Tanaka-Johnston analyses were performed. The data obtained were interpr...
