Recently, fibroblast growth factor-2 (FGF-2) agents for periodontal tissue regeneration have been increasingly applied to the treatment of periodontal disease. Our current challenge for resident dentists with little clinical experience is to enhance instruction in the handling of new medicine in addition to teaching conventional procedures in periodontal tissue regeneration. This report describes using case-specific, cost-effective three-dimensional (3D) models for dentists' lectures and periodontal surgical training. As an educational and training aid, preoperative and postoperative cone-beam computed tomography images were superimposed to enable three-dimensional observation of postoperative bone regeneration. A three-dimensional anatomical model was fabricated based on these images. Dental laboratory materials were used to reproduce the periosteum and gum. The fabrication time per 3D model was about 2 hours and the cost per model was about $0.5. These models were used for lectures to resident dentists and periodontal surgery training, and their feedback was obtained. The resident's response to surgical training using these 3D models was generally positive. The use of FGF-2 represents a new direction in the treatment of periodontal disease. This being new, however, means that inexperienced periodontists require training in its application and how this will affect prognosis, as this will differ from that with more conventional techniques aimed at tissue regeneration. The low-cost 3D model presented in this report can be a valuable tool to help accomplish this in teaching inexperienced dentists, such as resident dentists.
近年来，用于牙周组织再生的成纤维细胞生长因子-2（FGF-2）制剂已越来越多地应用于牙周疾病的治疗。对于临床经验不足的住院牙医来说，我们目前面临的挑战是，除了教授牙周组织再生的传统程序外，还要加强新药使用方面的指导。本报告描述了如何使用针对具体病例、成本效益高的三维（3D）模型进行牙医讲座和牙周手术培训。作为一种教育和培训辅助工具，术前和术后的锥形束计算机断层扫描图像被叠加在一起，以便对术后骨再生进行三维观察。基于这些图像制作了一个三维解剖模型。牙科实验室材料被用于重现骨膜和牙龈。每个3D模型的制作时间约为2小时，每个模型的成本约为0.5美元。这些模型被用于对住院牙医的讲座和牙周手术培训，并获得了他们的反馈。住院医生对使用这些3D模型进行手术培训的反应总体上是积极的。FGF-2的使用代表了牙周疾病治疗的一个新方向。然而，由于这是新的治疗方法，缺乏经验的牙周病医生需要接受关于其应用以及这将如何影响预后的培训，因为这与更传统的组织再生技术不同。本报告中介绍的低成本3D模型可以成为帮助在教学中让缺乏经验的牙医（如住院牙医）掌握这方面知识的宝贵工具。
