Abstract

Purpose: Dynamic navigation systems and surgical guides have been reported to be equally accurate. However, the accuracy of dynamic navigation systems is affected by the movement of the patient tracker fixed to the tooth. We hypothesized that fixing the patient tracker to the oral appliance could improve accuracy. Therefore, this study aimed to compare accuracy between a dynamic navigation system with a patient tracker fixed to an oral appliance and a surgical guide.

Methods: This observational study was conducted on patients who had undergone complete implant treatment at Kanagawa Dental University from 2020 to September 2024. Fifty implant bodies were placed in 42 patients with anterior tooth defects in both the dynamic navigation and surgical guide groups (25 implants each). DTX Studio™ (Nobel Biocare AG, Kloten, Switzerland) was used to overlay planning data on postoperative Digital Imaging and Communications in Medicine data to calculate entry point, apex point, and angular deviation accuracy.

Results: The entry point, apex point, and angular deviation values were 0.99 ± 0.33 mm, 0.97 ± 0.43 mm, and 2.64 ± 0.87° in the dynamic navigation group and 1.33 ± 0.26 mm, 1.38 ± 0.3 mm, and 3.42 ± 1.03° in the surgical guide group, respectively, differing significantly at all measurement sites (P < 0.01).

Conclusions: The fixation of the X-clip to the oral appliance improved intra-oral stability and inhibited intraoperative movement of the X-clip, resulting in high accuracy. These results suggest that dynamic navigation by oral appliance fixation is more accurate than surgical guides.

动态导航系统和手术指南的临床准确性评估,使用口腔器械固定的患者跟踪器瞄准前牙。
目的:据报道,动态导航系统和手术指南同样准确。然而,动态导航系统的准确性受到固定在牙齿上的患者跟踪器的运动的影响。我们假设将患者追踪器固定在口腔矫治器上可以提高准确性。因此,本研究旨在比较将患者跟踪器固定在口腔矫治器上的动态导航系统与手术导尿管之间的准确性。方法:本观察性研究对2020年至2024年9月在神奈川牙科大学接受全种植治疗的患者进行研究。在42例前牙缺损患者中,采用动态导航组和手术引导组各25个种植体。DTX Studio™(Nobel Biocare AG, Kloten, Switzerland)用于将计划数据叠加在术后数字成像和医学通信数据上,以计算切入点、顶点和角偏差精度。结果:动态导航组的入点、顶点和角偏差值分别为0.99±0.33 mm、0.97±0.43 mm和2.64±0.87°,手术导引组的入点、顶点和角偏差值分别为1.33±0.26 mm、1.38±0.3 mm和3.42±1.03°,各测量部位差异均有统计学意义(P)结论:X-clip固定在口腔矫治器上,提高了口腔内稳定性,抑制了X-clip术中移动,测量精度较高。这些结果表明,动态导航的口腔器械固定比手术导引更准确。
