The purpose of this paper is to outline a simple and effective digital protocol for in-house 3D-printing of orthognathic splints for use during single-jaw orthognathic surgery. Using this protocol, an intraoral scanner, and virtual planning software, computer-designed splints were fabricated by a rapid prototyping machine in-house. The protocol was utilized for 35 consecutive patients requiring single-jaw orthognathic surgery between January 2019 and March 2020. The total time from initial scan to splint fabrication for each case was between 5 and 9hours, including 3minutes for scanning of models, 4.5minutes for development of the splint, and 4-8hours for rapid prototyping and post-processing. This time varied based on the complexity of the design and the number of splints printed simultaneously. The average cost of raw materials for each splint was $0.73 Canadian dollars.
本文旨在概述一种简单有效的内部 3D 打印正颌夹板的数字方案，用于单颌正颌手术。使用该方案、口内扫描仪和虚拟规划软件，通过快速成型机在内部制作计算机设计的夹板。该方案于 2019 年 1 月至 2020 年 3 月期间用于 35 例连续的单颌正颌手术患者。每个病例从初始扫描到夹板制作的总时间在 5 到 9 小时之间，包括模型扫描 3 分钟、夹板制作 4.5 分钟和快速成型及后处理 4-8 小时。此时间取决于设计的复杂性和同时打印的夹板数量。每个夹板的原材料平均成本为 0.73 加元。
