Three-dimensional (3D) printing is relatively a new technology with clinical applications, which enable us to create rapid accurate prototype of the selected anatomic region, making it possible to plan complex surgery and pre-bend hardware for individual surgical cases. This study aimed to express our experience with the use of medical rapid prototype (MRP) of the maxillofacial region created by desktop 3D printer and its application in maxillofacial reconstructive surgeries.
Three patients with benign mandible tumors were included in this study after obtaining informed consent. All patient's maxillofacial CT scan data was processed by segmentation and isolation software and mandible MRP was printed using our desktop 3D printer. These models were used for preoperative surgical planning and prebending of the reconstruction plate.
MRP created by desktop 3D printer is a cost-efficient, quick and easily produced appliance for the planning of reconstructive surgery. It can contribute in patient orientation and helping them in a better understanding of their condition and proposed surgical treatment. It helps surgeons for pre-operative planning in the resection or reconstruction cases and represent an excellent tool in academic setting for residents training. The pre-bended reconstruction plate based on MRP, resulted in decreased surgery time, cost and anesthesia risks on the patients. 3D printing, medical modeling, rapid prototype, mandibular reconstruction, ameloblastoma.
三维（3D）打印是一项相对较新的临床应用技术，它使我们能够创建所选解剖区域的快速精确原型，从而有可能为复杂手术制定计划并为个别手术病例预弯硬件。本研究旨在分享我们使用桌面3D打印机创建的颌面区域医学快速原型（MRP）的经验及其在颌面重建手术中的应用。
在获得知情同意后，本研究纳入了3例下颌骨良性肿瘤患者。所有患者的颌面CT扫描数据均通过分割和隔离软件进行处理，并使用我们的桌面3D打印机打印下颌骨MRP。这些模型用于术前手术规划和重建钢板的预弯。
桌面3D打印机创建的MRP是一种经济高效、快速且易于制作的重建手术规划工具。它有助于患者了解自身情况，更好地理解病情和拟行的手术治疗。它有助于外科医生在切除或重建病例中进行术前规划，是学术环境中住院医师培训的优秀工具。基于MRP预弯的重建钢板可减少手术时间、成本和患者的麻醉风险。3D打印、医学建模、快速原型、下颌骨重建、成釉细胞瘤。
