In implant dentistry today, precise preoperative planning of both the implant placement and the restoration is a critical prerequisite to succeeding in the oral rehabilitation of patients with dental implants. Modern three-dimensional imaging techniques such as digital volume tomography allow the acquisition of radiologic data with very low levels of radiation and excellent image accuracy, and also allow the processing of these data with various types of software applications. Formerly, only the position of the implant collar or the axis of the osteotomy could be transferred into the clinical setting; it is now possible to predetermine the precise three-dimensional position of the planned implant before the actual implant insertion, and to transfer this position to the surgical site. Thus, the restoration can be fabricated before surgery and can be placed into the patient's mouth immediately after surgery. Treatment planned in this way is fast, minimally invasive, and most importantly, predictable. This increases the quality of both the surgical procedure and the restoration. For three-dimensional navigation in implant dentistry there are static systems based on both surgical guides and optical, dynamic navigation systems. This article is an overview of the latest systems for guided implant insertion and their fields of application.
在当今的种植牙科领域，对种植体植入和修复进行精确的术前规划是成功实现牙种植体患者口腔修复的关键前提。现代三维成像技术，如数字容积断层扫描，能够以极低的辐射水平获取放射学数据，且图像精度极高，还能通过各种软件应用程序对这些数据进行处理。以前，只能将种植体颈部的位置或截骨术的轴线转移到临床环境中；现在，在实际植入种植体之前就可以预先确定计划种植体的精确三维位置，并将该位置转移到手术部位。因此，可以在手术前制作修复体，并在手术后立即放入患者口中。以这种方式规划的治疗快速、微创，最重要的是可预测。这提高了手术过程和修复体的质量。对于种植牙科中的三维导航，有基于手术导板的静态系统和光学动态导航系统。本文概述了用于引导种植体植入的最新系统及其应用领域。
