Intraobserver and interobserver reproducibility in linear measurements on axial images obtained by cone-beam computed tomography
PURPOSE This study was performed to investigate the intra- and inter-observer variability in linear measurements with axial images obtained by PreXion (PreXion Inc., San Mateo, USA) and i-CAT (Imaging Sciences International, Xoran Technologies Inc., Hatfield, USA) CBCT scanners, with different voxel sizes. MATERIALS AND METHODS A cylindrical object made from nylon with radiopaque markers (pha...
متن کاملAssessment of Accessory Mental Foramen by Cone-Beam Computed Tomography
Introduction: Any foramen in the buccal surface of mandibular body that transfers mental nerve and vessels except mental foramen, is called Accessory Mental Foramen (AMF). The objective of this study was the determination of the AMF using cone-beam computed tomography (CBCT). Materials and Methods: this descriptive study was done on 180 CBCT projections which were selected by convenience samp...
متن کاملEvaluation of digital dental models obtained from dental cone-beam computed tomography scan of alginate impressions
OBJECTIVE To investigate the dimensional accuracy of digital dental models obtained from the dental cone-beam computed tomography (CBCT) scan of alginate impressions according to the time elapse when the impressions are stored under ambient conditions. METHODS Alginate impressions were obtained from 20 adults using 3 different alginate materials, 2 traditional alginate materials (Alginoplast ...
متن کاملComparative study of mandibular linear measurements obtained by cone beam computed tomography and digital calipers
OBJECTIVES Cone beam computed tomography (CBCT) is an innovative dental of imaging system characterized by rapid volumetric imaging with patient exposure to a single dose of radiation. The present study was carried out to compare the linear measurements obtained with CBCT and digital caliper in 20 mandibles from human cadavers. STUDY DESIGN A total of 4800 linear measurements were measured be...
متن کاملArtifacts of Titanium, Zirconium, and Binary Titanium-Zirconium Abutments in Compute Tomography, Cone Beam Computed Tomography, and Magnetic Resonance Imaging
Aim: The aim of this in vitro study was to evaluate imaging artifacts induced by Titanium, Zirconium, Titanium-Zirconium abutments in CT, MRI and CBCT imaging modalities.Methods: A 4×8mm titanium fixture was inserted in a dry human mandible. Titanium, Zirconium and Titanium–Zirconium abutments measuring 10.5 mm in height are located on the fixture, one by one. Each abutment was scan...
