摘要

目的:验证计算机辅助动态颧骨种植手术中基准标记数量和配置对目标配准误差(TRE)的影响。材料和方法:纳入2018年1月至2021年12月接受导航颧骨植入术的所有患者。对于每位患者,在手术前将6-8个迷你螺钉作为基准标记放置在口内。在配准过程之后,计算TRE,其表示图像空间的目标和基准标记的真实位置之间的距离。统计分析采用SPSS(22.0)软件。结果:在47例患者中,共放置了325个微型钛螺钉,这些患者通过导航进行了颧骨植入术。最低TRE为0.2 mm,而最高TRE为1.9 mm。不同钛微型螺钉组之间的平均TRE值没有显著差异(P=.07)。在导航手术之前和期间,7名患者中共有8名微型螺钉在上颌结节区域丢失,这导致基准标记物的不规则多边形分布。然而,多边形分布(0.62±0.35 mm)和不规则多边形分布(0.68±0.33 mm)之间的TRE没有统计学上的显著差异(P=.35)。配准误差似乎不受多边形分布中缺少一个角的影响。

The Effect of Fiducial Marker Number and Configuration on Registration Error in Dynamic Implant Surgery.

Objective: To verify the effect of fiducial marker number and configuration on target registration error (TRE) for dynamic computer-aided zygomatic implant surgery. Material and Methods: All patients who underwent zygomatic implant surgery with navigation from January 2018 to December 2021 were enrolled. For each patient, 6 to 8 miniscrews were placed intraorally as fiducial markers before the surgery. After the registration procedure, the TRE, which represents the distance between the target of the image space and the real position of the fiducial markers, was calculated. SPSS (22.0) was used for statistical analysis. Results: A total of 325 titanium miniscrews were placed in 47 patients who underwent zygomatic implant placement by navigation. The lowest TRE was 0.2 mm, compared to the highest TRE of 1.9 mm. There was no significant difference in the mean TRE value among the different titanium miniscrew groups (P = .07). A total of 8 miniscrews in 7 patients were lost in the maxillary tuberosity area prior to and during navigation surgery, which resulted in an irregular polygonal distribution of fiducial markers. However, there was no statistically significant difference in TRE between a polygonal distribution (0.62 ± 0.35 mm) and an irregular polygonal distribution (0.68 ± 0.33 mm) (P = .35). Conclusion: A scattered, polygonal distribution with of a minimum of five fiducial markers in an edentulous maxilla could achieve acceptable TRE values in registration. It seems that the registration error was not influenced by the absence of one corner in a polygon distribution.

期刊介绍: Edited by Steven E. Eckert, DDS, MS ISSN (Print): 0882-2786 ISSN (Online): 1942-4434 This highly regarded, often-cited journal integrates clinical and scientific data to improve methods and results of oral and maxillofacial implant therapy. It presents pioneering research, technology, clinical applications, reviews of the literature, seminal studies, emerging technology, position papers, and consensus studies, as well as the many clinical and therapeutic innovations that ensue as a result of these efforts. The editorial board is composed of recognized opinion leaders in their respective areas of expertise and reflects the international reach of the journal. Under their leadership, JOMI maintains its strong scientific integrity while expanding its influence within the field of implant dentistry. JOMI’s popular regular feature "Thematic Abstract Review" presents a review of abstracts of recently published articles on a specific topical area of interest each issue.
