Evaluation of the accuracy of cone beam computed tomography (CBCT) generated tooth replicas with application in autotransplantation.

Objectives: The primary aim of this study was to assess the linear and geometric accuracy of 3-dimensional (3D) printed tooth replicas when compared to the actual tooth. The secondary aims were to compare the accuracy of three different 3D printers and to evaluate dimensional changes of tooth replicas after sterilization.

Methods: A sample of 16 teeth were selected from recruited patients.
