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.
描述了采用三维计算机辅助牙髓治疗入路技术（CEAT-3D），利用计算机辅助设计和计算机辅助制造（CAD-CAM）技术以微创方式从后牙中取出纤维桩的临床治疗方法。三名患有症状性磨牙和根尖周透射区且治疗复杂性不同的患者被转诊进行牙髓再治疗。为了取出纤维桩并进行牙髓再治疗，使用数字规划软件程序根据口腔内和锥形束计算机断层扫描（CBCT）扫描设计了三维打印导板。在每位患者中，使用1.3×20毫米的钻头通过三维打印导板在持续用盐溶液冲洗下取出纤维桩。
