To clinically evaluate 3D print-formed implant process, using cranioplasty as a proof of concept, to examine its effectiveness and utility as a method of intraoperative implant fabrication.
Twelve patients had a 3D print-formed template created for patient-specific implant manufacture. Of these patients, 10 received intraoperatively formed polymethylmethacrylate cranioplasty implants between 2013 and 2019. The 3D print-formed implant templates produced to manufacture these patient-specific implants were generated using patient computed tomography scans and 3D printed using fused deposition modelling technology. Cosmetic and functional results were determined by participating surgeons, in conjunction with a patient questionnaire.
The functional results and stability of the implants were deemed to be favourable by participating surgeons. Three of the 10 patients completed a post-cranioplasty survey, all of whom judged their cosmetic results as good or excellent. At time of writing, the rate of surgical revision was zero and without clinically adverse outcomes.
3D print-formed implants are an effective method of patient-specific implant formation.
以颅骨成形术作为概念验证，对3D打印成型植入物工艺进行临床评估，以检验其作为术中植入物制造方法的有效性和实用性。
为12例患者创建了用于制造定制植入物的3D打印模板。其中，10例患者在2013年至2019年间接受了术中成型的聚甲基丙烯酸甲酯颅骨成形术植入物。用于制造这些定制植入物的3D打印成型植入物模板是使用患者计算机断层扫描生成的，并采用熔融沉积建模技术进行3D打印。由参与手术的外科医生结合患者问卷来确定美容和功能结果。
参与手术的外科医生认为植入物的功能结果和稳定性良好。10例患者中有3例完成了颅骨成形术后调查，他们均认为自己的美容效果为良好或极佳。在撰写本文时，手术翻修率为零，且无临床不良后果。
3D打印成型植入物是一种有效的定制植入物成型方法。
