Abstract

An existing interim obturator can be reproduced as the definitive one using digital technology, with benefits for a patient with a maxillectomy. By digitally scanning the oral condition and the existing interim obturator, a definitive obturator, including a computer-aided designed and computer-aided manufactured metal framework, was fabricated and delivered to a patient with an anterior maxillectomy defect by following a combined digital and conventional workflow. This technique can hasten the adaptation of the patient to the new obturator and ensure a more comfortable and safer clinical procedure.

摘要

使用数字技术可以将现有的临时闭孔器复制为定制的最终闭孔器，这对接受上颌骨切除术的患者有益。通过对口腔状况和现有的临时闭孔器进行数字扫描，按照数字与传统相结合的工作流程，制作了一个定制的最终闭孔器，包括计算机辅助设计和计算机辅助制造的金属框架，并交付给一名患有上颌前部骨切除缺损的患者。该技术可以加快患者对新闭孔器的适应，并确保临床操作更加舒适和安全。
