Three-dimensional printing is a rapidly developing area of technology and manufacturing in the field of oral surgery. The aim of this study was comparison of presurgical models made by two different types of three-dimensional (3D) printing technology. Digital reference models were printed 10 times using fused deposition modelling (FDM) and digital light processing (DLP) techniques. All 3D printed models were scanned using a technical scanner. The trueness, linear measurements, and printing time were evaluated. The diagnostic models were compared with the reference models using linear and mean deviation for trueness measurements with computer software. Paired -tests were performed to compare the two types of 3D printing technology. A value < 0.05 was considered statistically significant. For FDM printing, all average distances between the reference points were smaller than the corresponding distances measured on the reference model. For the DLP models, the average distances in the three measurements were smaller than the original. Only one average distance measurement was greater. The mean deviation for trueness was 0.1775 mm for the FDM group and 0.0861 mm for the DLP group. Mean printing time for a single model was 517.6 minutes in FDM technology and 285.3 minutes in DLP. This study confirms that presurgical models manufactured with FDM and DLP technologies are usable in oral surgery. Our findings will facilitate clinical decision-making regarding the best 3D printing technology to use when planning a surgical procedure.
三维打印是口腔外科学领域中技术和制造的快速发展领域。本研究的目的是比较两种不同类型的三维（3D）打印技术制作的术前模型。使用熔丝制造（FDM）和数字光处理（DLP）技术打印数字参考模型 10 次。使用技术扫描仪扫描所有 3D 打印模型。评估准确性、线性测量和打印时间。使用计算机软件对诊断模型与参考模型进行线性和均值偏差比较，以评估准确性。进行配对检验以比较两种 3D 打印技术。认为 值<0.05 具有统计学意义。对于 FDM 打印，所有参考点之间的平均距离都小于参考模型上测量的相应距离。对于 DLP 模型，三个测量中的平均距离都小于原始距离。只有一个平均距离测量值较大。FDM 组的准确性均值偏差为 0.1775 毫米，DLP 组的准确性均值偏差为 0.0861 毫米。FDM 技术中单模型的平均打印时间为 517.6 分钟，DLP 技术的平均打印时间为 285.3 分钟。本研究证实，使用 FDM 和 DLP 技术制造的术前模型可用于口腔外科学。我们的发现将有助于临床决策，即在计划手术程序时使用哪种 3D 打印技术最佳。
