This article presents a digital technique for the fabrication of an immediate surgical obturator for a patient with decreased mouth opening planned for maxillectomy. The amalgamation of pre-operative Cone Beam Computed Tomography (CBCT) data and 3D printing allowed for the fabrication of the immediate surgical obturator without conventional pre-surgical diagnostic impression. The surgical obturator was placed in position intraorally post tumor resection to complete the obturation. The procedure followed led to an accurate fit of the prosthesis without any need for relining during surgery.
本文介绍了一种数字技术,用于为计划进行上颌骨切除术且张口受限的患者制作即刻外科阻塞器。术前锥形束计算机断层扫描(CBCT)数据与3D打印相结合,无需传统的术前诊断印模即可制作即刻外科阻塞器。肿瘤切除术后,将外科阻塞器经口放置到位以完成封闭。后续步骤使假体贴合准确,手术过程中无需重衬。
