Ideal implant placement may reduce surgical complications, such as nerve injury and lingual cortical plate perforation, and minimize the likelihood of functional and prosthetic compromises. Guided implant surgery [GIS] has been used as the means to achieve ideal implant placement. GIS refers to the process of digital planning, custom-guide fabrication, and implant placement using the custom guide and an implant system-specific guided surgery kit. GIS includes numerous additional steps beyond the initial prosthetic diagnosis, treatment planning, and fabrication of surgical guides. Substantial errors can occur at each of these individual steps and can accumulate, significantly impacting the final accuracy of the process with potentially disastrous deviations from proper implant placement. Pertinent overall strategies to reduce or eliminate these risks can be summarized as follows: complete understanding of the possible risks is fundamental; knowledge of the systems and tools used is essential; consistent verification of both diagnostic and surgical procedures after each step is crucial; proper training and surgical experience are critical. This review article summarizes information on the accuracy and efficacy of GIS, provides insight on the potential risks and problems associated with each procedural step, and offers clinically relevant recommendations to minimize or eliminate these risks.
理想的种植体植入可减少手术并发症，如神经损伤和舌侧皮质骨板穿孔，并将功能和修复受损的可能性降至最低。引导式种植手术（GIS）已被用作实现理想种植体植入的手段。GIS是指使用定制导板和特定种植系统的引导手术套件进行数字规划、定制导板制作以及种植体植入的过程。GIS包括了除最初的修复诊断、治疗计划和手术导板制作之外的许多额外步骤。在这些单独步骤中的每一步都可能出现重大误差，并且这些误差可能会累积，从而显著影响该过程的最终准确性，导致与正确的种植体植入产生潜在的灾难性偏差。减少或消除这些风险的相关总体策略可总结如下：全面了解可能的风险是根本；熟悉所使用的系统和工具至关重要；在每个步骤之后持续验证诊断和手术程序至关重要；适当的培训和手术经验至关重要。这篇综述文章总结了关于GIS准确性和有效性的信息，深入探讨了与每个程序步骤相关的潜在风险和问题，并提供了临床相关建议，以尽量减少或消除这些风险。
