Application of Industrial Computed Tomography (ICT) in Dentistry on 3D Printed Co-Cr Dental Bridge

Quality control of dental bridges in dentistry is an important area for several key reasons such as meeting high quality standards, identification of imperfections and volume defects (e.g. microcracks, porosity, irregularities), dimensional accuracy, etc. In this paper, tests were performed on additively manufactured 3D-printed and cast Co-Cr dental bridges. Surface comparison of Co-Cr dental bridges (3D-printed and cast) was carried out by checking the possibility of dimensional accuracy determination. Precise analysis of the 3D-printed Co-Cr dental bridge internal structure was performed using industrial computed tomography (iCT). The iCT analyzes were carried out from different observing perspectives of the 3D-printed Co-Cr dental bridges. The results from this study showed different applications of iCT and 3D scanning in quality control of dental bridges. The importance of iCT application in the field of dental bridges quality control was established.
