目的：本研究的目的是比较微米跟踪器动态导航装置和徒手辅助下计划和放置种植体的偏差。材料与方法在前牙上安装热塑性基准标记器，采用锥束CT进行成像。上颌后牙每侧至少计划一个种植体，并随机使用动态导航装置或徒手操作方法进行手术种植。通过将规划数据与最终的CBCT图像进行匹配来测量偏差。计划和放置的植入物之间的线性偏差(Mm)是主要结果。结果用广义线性混合模型(p<；0.05)进行分析。(NCT03471208)。结果32名志愿者共植入种植体92枚，86枚种植体进入最终分析。对于线性偏差，种植体肩部(P<；.001)和种植体尖端(P<；.001)的差值均值(Delta)为0.72 mm(标准差(SD)：0.26)，95%可信区间(CI)：0.39-1.02；种植体尖端(P<；.001)的差值(95%CI：0.19-1.19)。对于角度偏差，Delta为5.33度(SD：1.63)；(95%CI：7.17-3.48)；(p<；.001)。结论该导航技术可用于将虚拟种植计划传输到患者的颌骨，提高了准确性。
Objectives The aim of this split-mouth randomized controlled clinical trial was to compare the deviations of planned and placed implants placed by the assistance of a micron tracker-based dynamic navigation device or freehand methods. Material and methods A thermoplastic fiducial marker was adapted on the anterior teeth, and cone-beam computerized tomography was used for imaging. A minimum of one implant was planned for each side of the posterior maxilla, and the dynamic navigation device or freehand method was randomly used for surgical insertion. Deviations were measured by matching the planning data with a final CBCT image. Linear deviations (mm) between the planned and placed implants were the primary outcome. The results were analysed by generalized linear mixed models (p < .05). (NCT03471208). Results A total of 92 implants were placed to 32 volunteers, and 86 implants were included in the final analysis. For the linear deviations, mean of differences (Delta) was 0.72mm (Standard deviation (SD): 0.26); (95% Confidence interval (CI): 0.39-1.02) in the shoulder of the implants (p < .001) and 0.69mm (SD: 0.36); (95% CI: 0.19-1.19) in the tip of the implants (p < .001). For the angular deviations, Delta was 5.33 degrees (SD: 1.63); (95% CI: 7.17-3.48); (p < .001). Conclusions The navigation technique can be used to transfer virtual implant planning to the patient's jaw with increased accuracy.
