Abstract

Aim: The aim of the present ex vivo study was to examine the accuracy of augmented reality-assisted apicoectomies (AR-A) versus template-guided apicoectomies (TG-A).

Materials and methods: In total, 40 apicoectomies were performed in 10 cadaver pig mandibles. Every pig mandible underwent two AR-A and two TG-A in molar and premolar teeth. A crossed experimental design was applied. AR-A was performed using Microsoft HoloLens 2, and TG-A using SMOP software. Postoperative CBCT scans were superimposed with the presurgical planning data. The deviation between the virtually planned apicoectomy and the surgically performed apicoectomy was measured. The primary (angular deviation [degrees]) and secondary (depth deviation [mm]) outcome parameters were measured.

Results: Overall, 36 out of 40 apicoectomies could be included in the study. Regarding the primary outcome parameter (angular deviation), there was no significant difference between AR-A and TG-A. The mean values were 5.33 degrees (± 2.96 degrees) in the AR-A group, and 5.23 degrees (± 2.48 degrees) in the TG-A group. The secondary outcome parameter (depth deviation) showed no significant difference between the AR-A group of 0.27 mm (± 2.32 mm) and the TG-A group of 0.90 mm (± 1.84 mm). In this crossed experimental design, both techniques overshot the target depth in posterior sites, as opposed to not reaching the target depth in anterior sites (P < 0.001).

Conclusion: Augmented reality (AR) technology has the potential to be introduced into apicoectomy surgery in case further development is implemented.

增强现实辅助与模板引导的根尖切除术的准确性-一项离体比较研究。

目的:本离体研究的目的是检验增强现实辅助根尖切除术(AR-A)与模板引导根尖切除术(TG-A)的准确性。材料与方法:对10只死猪下颌骨进行根尖切除术，共40例。每头猪下颌骨在磨牙和前磨牙上分别行2个AR-A和2个TG-A。采用交叉试验设计。AR-A采用Microsoft HoloLens 2, TG-A采用SMOP软件。术后CBCT扫描与术前计划数据叠加。测量虚拟计划的根尖切除术与手术实施的根尖切除术之间的偏差。测量主要(角度偏差[度])和次要(深度偏差[mm])结局参数。结果:总的来说，40例根尖切除术中有36例可以纳入研究。关于主要结局参数(角度偏差)，AR-A和TG-A之间无显著差异。AR-A组平均值为5.33度(±2.96度)，TG-A组平均值为5.23度(±2.48度)。次要结局参数(深度偏差)AR-A组为0.27 mm(±2.32 mm)， TG-A组为0.90 mm(±1.84 mm)，差异无统计学意义。在这个交叉实验设计中，两种技术在后侧部位都超过了目标深度，而在前侧部位没有达到目标深度(P < 0.001)。结论:增强现实(AR)技术在根尖切除手术中有进一步发展的潜力。

期刊介绍： This journal explores the myriad innovations in the emerging field of computerized dentistry and how to integrate them into clinical practice. The bulk of the journal is devoted to the science of computer-assisted dentistry, with research articles and clinical reports on all aspects of computer-based diagnostic and therapeutic applications, with special emphasis placed on CAD/CAM and image-processing systems. Articles also address the use of computer-based communication to support patient care, assess the quality of care, and enhance clinical decision making. The journal is presented in a bilingual format, with each issue offering three types of articles: science-based, application-based, and national society reports.
