Purpose

This study aims to assess the design, manufacturing and surgical implantation of three-dimensional (3D) customized implants, including surgical preoperative planning, surgery and postoperative results, for cranioplasty along with zygomatic and orbital floor implants using additive manufacturing (AM) technics for a 23-year-old female who suffered from severe craniomaxillofacial trauma.

Design/methodology/approach

The skull biomodel was produced in polyamide while implants were made of a Ti-6Al-4V alloy by AM.

Findings

The method enabled perfectly fitting implants and anatomical conformance with the craniomaxillofacial defect, providing complete healing for the patient. Surgical planning using a customized 3D polyamide biomodel was effective. This proved to be a powerful tool for medical planning and manufacturing of customized implants, as complete healing and good craniofacial aesthetic results were observed.

Originality/value

Satisfactory surgical procedures, regarding surgery time reduction and good craniofacial aesthetic results, were achieved. Furthermore, the 3D titanium customized implants represented a favorable alternate for the repair of craniomaxillofacial defects.

使用增材制造定制植入物对复杂颅颌面畸形进行骨重建手术 - 案例报告

目的

本研究旨在评估三维 (3D) 定制植入物的设计、制造和手术植入，包括使用增材制造 (AM) 技术进行颅骨成形术以及颧骨和眶底植入物的手术术前计划、手术和术后结果。 23 岁女性，颅颌面严重外伤。

设计/方法/方法

头骨生物模型由聚酰胺制成，而植入物由 AM 由 Ti-6Al-4V 合金制成。

发现

该方法使植入物与颅颌面缺损完美贴合，解剖结构符合，为患者提供完全愈合。使用定制的 3D 聚酰胺生物模型进行手术规划是有效的。这被证明是定制植入物的医疗规划和制造的强大工具，因为观察到了完全愈合和良好的颅面美学效果。

原创性/价值

在减少手术时间和良好的颅面美学效果方面取得了令人满意的手术过程。此外，3D 钛定制植入物代表了修复颅颌面缺损的有利替代方案。
