Implant placement in orbital sites is challenging because of limited bone volume and poor bone quality. Preoperative optimal implant planning and intraoperative guides are important to ensure success. This article describes the use of computer simulation for implant insertion and fabrication of a surgical template as a drilling guide for orbital implant placement. A 29-year-old woman with a right orbital defect underwent computerized tomographic scanning, and the data were processed with interactive software to simulate orbital implant placement. A surgical template that served as a drilling guide was designed and fabricated to transfer orbital recipient site information from the three-dimensional computer model into the actual orbital implant sites. Three craniofacial implants were placed in the 7:00, 8:00, and 11:00 positions. No unexpected complications or injuries were encountered during the surgery. Magnetic abutments were attached to the implants 2 weeks later. The definitive facial prosthesis was fitted 6 months later, with excellent esthetic results. The surgical template contributed to the success of this treatment.
由于眶骨体积有限和骨质量差,眶内植入物的放置具有挑战性。术前进行最佳的植入物规划和术中导板对于确保手术成功非常重要。本文描述了计算机模拟在植入物插入和制作手术模板方面的应用,该模板可用作眶内植入物放置的钻引导。一名 29 岁的女性患者右眼眶有缺损,对其进行计算机断层扫描,使用交互式软件处理数据以模拟眶内植入物的放置。设计并制作了一个手术模板,用作钻引导,将三维计算机模型中的眶内受植区信息转移到实际的眶内植入部位。在 7 点、8 点和 11 点位置分别放置了 3 个颅面植入物。手术过程中未出现意外并发症或损伤。2 周后,将磁附着体连接到植入物上。6 个月后,安装了最终的面部假体,效果非常理想。手术模板为该治疗的成功做出了贡献。
