Abstract

Clinical treatments employing a 3-dimensional computer-assisted endodontic access technique (CEAT-3D) to remove fiber posts from posterior teeth in a minimally invasive manner using computer-aided design and computer-aided manufacturing (CAD-CAM) technology are described. Three patients with symptomatic molars and periapical radiolucency and with different treatment complexities had been referred for endodontic retreatment. For the removal of the fiber posts and endodontic retreatment, 3-dimensionally printed guides were designed from intraoral and cone beam computed tomography (CBCT) scans with a digital planning software program. In each patient, the fiber posts were removed with a 1.3×20-mm drill through the 3-dimensionally printed guide under constant irrigation with saline solution.
