Accuracy of linear measurement using cone-beam computed tomography at different reconstruction angles
PURPOSE This study was performed to evaluate the effect of changing the orientation of a reconstructed image on the accuracy of linear measurements using cone-beam computed tomography (CBCT). MATERIALS AND METHODS Forty-two titanium pins were inserted in seven dry sheep mandibles. The length of these pins was measured using a digital caliper with readability of 0.01 mm. Mandibles were radiogr...
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 of linear measurements using cone beam computed tomography in comparison with clinical measurements
objectives: this study sought to evaluate the accuracy and errors of linear measurements of mesiodistal dimensions of kennedy class iii edentulous space using cone beam computed tomography (cbct) in comparison with clinical measurements. materials and methods: nineteen kennedy class iii dental arches were evaluated. an impression was made of each dental arch and poured with dental stone. the di...
متن کاملaccuracy and reliability of linear measurements using tangential projection and cone beam computed tomography
background: providing a cross-sectional image is essential for preimplant assessments. computed tomography (ct) and cone beam ct (cbct) images are very expensive and provide high radiation dose. tangential projection is a very simple, available, and low-dose technique that can be used in the anterior portion of mandible. the purpose of this study was to evaluate the accuracy of tangential proje...
متن کاملAnalysis of linear measurement accuracy obtained by cone beam computed tomography (CBCT-NewTom VG)
BACKGROUND One of the major uses of cone beam computed tomography (CBCT) is presurgical implant planning. Linear measurement is used for the determination of the quantity of alveolar bone (height and width). Linear measurements are used in orthodontic analysis and definition of jaw tumor size. The objective of this study is to evaluate the accuracy of the linear measurement of CBCT (Newtom VG) ...
