Background As the anatomical three-dimensional (3D) posi- using a 3D printer, showed favorable anatomical reproducibil- tional relationship around the anterior clinoid process (ACP) ity, including reproduction of the intraosseous region.

The objective of this study was to evaluate anatomical reproduction of the 3D synthetic image and intraosseous re- gion after AC in the RP model.
