Comparative Analysis of Artifact Expression in Zirconia and Graphene Crowns in CBCT Images From Different Systems. [PDF]

Int J Dent
Introduction Comparing artifact expression in emerging materials, like zirconia, known for high artifact generation, to lower‐density materials like graphene is essential to find ways to minimize it. Evaluating these materials across cone‐beam computed tomography (CBCT) systems and acquisition protocols provides a comprehensive performance assessment ...
