Abstract

Objective: Dynamic navigation approaches are widely employed in the context of implant placement surgery. Implant surgery can be divided into immediate and delayed surgery according to the time of implantation. This retrospective study was developed to compare the accuracy of dynamic navigation system for immediate and delayed implantations.

Methods: In the study, medical records from all patients that had undergone implant surgery between August 2019 and June 2021 in the First Clinical Division of the Peking University School and Hospital of Stomatology were retrospectively reviewed. There were 97 patients [53 males and 44 females, average age (47.14±11.99) years] and 97 implants (delayed group: 51; immediate group: 46) that met with study inclusion criteria and were included. Implant placement accuracy was measured by the superposition of the planned implant position in the preoperative cone beam computed tomography (CBCT) image and the actual implant position in the postoperative CBCT image. The 3-dimensional (3D) entry deviation (3D deviation in the coronal aspect of the alveolar ridge), 3D apex deviation (3D deviation in the apical area of the implant) and angular deviation were analyzed as the main observation index when comparing these two groups. The 2-dimensional (2D) horizontal deviation of the entry point and apex point, and the deviation of entry point depth and apex point depth were the secondary observation index.

Results: The overall implant restoration survival rate was 100%, and no mechanical or biological complications were reported. The implantation success rate was 100%. The 3D entry deviation, 3D apex deviation and angular deviation of all analyzed implants were (1.146±0.458) mm, (1.276±0.526) mm, 3.022°±1.566°, respectively; while in the delayed group these respective values were (1.157±0.478) mm, (1.285±0.481) mm and 2.936°±1.470° as compared with (1.134±0.440) mm, (1.265±0.780) mm, 3.117°±1.677° in the immediate group. No significant differences (P=0.809, P=0.850, P=0.575) in accuracy were observed when comparing these two groups.

Conclusion: Dynamic computer-assisted implant surgery system promotes accurate implantation, and both the immediate and delayed implantations exhibit similar levels of accuracy under dynamic navigation system that meets the clinical demands. Dynamic navigation system is feasible for immediate implantation.

动态导航系统用于即刻种植牙的准确性。

目的：动态导航入路在种植体置入术中被广泛应用。根据种植时间的不同，种植手术可分为立即种植和延迟种植。本回顾性研究旨在比较动态导航系统在即刻植入和延迟植入中的准确性。方法：回顾性分析2019年8月至2021年6月北京大学附属口腔医院临床一科所有种植体手术患者的病历。97例患者（男53例，女44例，平均年龄（47.14±11.99）岁），种植体97例(延迟组51例；直接组：46例符合研究纳入标准的患者。通过术前锥形束计算机断层扫描（CBCT）图像中计划种植体位置与术后CBCT图像中实际种植体位置的叠加来测量种植体放置精度。比较两组的主要观察指标为三维（3D）入牙偏差（牙槽嵴冠状面三维偏差）、三维尖牙偏差（种植体尖区三维偏差）和角度偏差。入口点与顶点的二维水平偏差、入口点深度与顶点深度的偏差为次要观测指标。结果：种植体整体成活率100%，无机械、生物并发症。植入成功率100%。所有种植体的三维入牙偏差、三维尖牙偏差和角度偏差分别为（1.146±0.458）mm、（1.276±0.526）mm、3.022°±1.566°；延迟组分别为（1.157±0.478）mm、（1.285±0.481）mm、2.936°±1.470°，而立即组分别为（1.134±0.440）mm、（1.265±0.780）mm、3.117°±1.677°。两组比较准确率无显著差异（P=0.809， P=0.850， P=0.575）。结论：动态计算机辅助种植手术系统可提高种植精度，动态导航系统下即刻种植和延迟种植的种植精度相近，满足临床需求。动态导航系统是可行的即时植入。
