Abstract

Introduction: In recent years, three-dimensional (3D) printing has emerged as a new manufacturing technique for orthoses, showing comparable stability and wearing comfort to traditional orthoses. However, the lengthy designing and printing process is assumed to take more time than the common practice of manufacturing low-temperature thermoplastic orthoses (LTTOs). The aim of this prospective cross-sectional study was to compare the production time of 3D-printed orthoses (3DPO) to LTTOs.

Methods: The active and passive time needed to manufacture the orthoses was measured in a clinical setting. 17 orthoses (8 3DPOs and 9 LTTOs) were included in the data analysis.

Results: The mean total production time of a 3DPO (12:14:50h total time; 0:44:35h active production time) was significantly longer than in LTTOs (0:14:14h; p < 0.001).

Discussion: The longer production time might be a hurdle regarding the implementation of 3DPOs in hand therapy. Although 3D-printing might become more cost- and time-efficient due to future developments in technology and growing experience, some practical advantages of LTTOs prevail, such as the fast and efficient provision of orthoses and the adaptability of the material if subsequent changes are needed. A combination of both manufacturing techniques may be a feasible solution to provide patient-centred orthosis provision in future hand therapy practice.

三维打印腕部矫形器与低温热塑腕部矫形器的生产时间和实用性对比。
简介:近年来,三维(3D)打印已成为一种新的矫形器制造技术,其稳定性和穿着舒适度与传统矫形器不相上下。然而,与制造低温热塑矫形器(LTTOs)的常见做法相比,冗长的设计和打印过程被认为需要花费更多时间。这项前瞻性横断面研究旨在比较三维打印矫形器(3DPO)与低温热塑矫形器的生产时间:方法:在临床环境中测量制造矫形器所需的主动和被动时间。数据分析包括 17 个矫形器(8 个 3DPO 和 9 个 LTTO):结果:3DPO的平均总生产时间(总时间12:14:50小时;主动生产时间0:44:35小时)明显长于LTTO(0:14:14小时;P < 0.001):讨论:较长的生产时间可能是在手部治疗中使用 3DPOs 的一个障碍。尽管随着未来技术的发展和经验的积累,3D打印技术可能会变得更加节约成本和时间,但LTTOs仍具有一些实际优势,如快速、高效地提供矫形器,以及在需要进行后续更改时材料的适应性。在未来的手部治疗实践中,两种制造技术的结合可能是一种可行的解决方案,可以提供以患者为中心的矫形器。
