The combined CBCT and 3-d printing have found its endodontic application in pre-surgical planning models, endodontic access guides and localization of osteotomy preparation site. This article reports a series of three cases where this combined technology have been used. The first case report is of radicular dens invaginatus which was diagnosed by using cone-beam computed tomography (CBCT) imaging and 3D plastic models of the tooth. The case was managed successfully by the combination of both surgical and non-surgical endodontic treatment. The second case report is the guided access preparation of lower anterior teeth. A 3D printed template was designed with the CBCT scan for the guided access cavity preparation and was compared with the conventional endodontic access cavity preparation. The third case report is the surgical template guided hemisection. A 3D surgical template was designed which allowed precise angulation of the bur and minimized the excess removal of tooth structure. Thus, the combined use of CBCT and 3D printing enabled visualization of complex root canal anatomies and allowed precise and accurate treatment.
