Abstract

Purpose: Computed tomography (CT) imaging is utilized during virtual surgical planning (VSP) in orthognathic surgery to simulate the surgical scenario, thereby aiding the actual surgery. Various surgical strategies exist to enhance accuracy in Le Fort I osteotomy, but an ideal planning and treatment approach has not yet been defined. The purpose of this study was to assess the accuracy of markerless Augmented Reality (AR), utilizing the iterative closest point algorithm for real-time tracking without 3D-printed surgical guides, wafers, or physical markers. The study explores the integration of VSP and an intraoperative markerless AR-assisted system for Le Fort I osteotomy in orthognathic surgery.

Methods: Six patients were enrolled in the study. We conducted a markerless AR-assisted orthognathic surgery utilizing VSP containing a virtual plate model. To assess accuracy, the postoperative 3-dimensional reconstructed CT image was compared to the VSP.

Results: Distance maps visualizing the distances between VSP and the postoperative CT scan revealed an accuracy with a standard deviation (SD) of 0.81 mm (81.0% within 1 mm) in terms of the maxillary position.

Conclusions: This approach facilitated the movement and positioning of the maxillary bone along with fixation and setting of titanium plates. The simulation of the surgical procedure made the process more straightforward, enabling us to perform the actual surgery with greater precision. The markerless AR-assisted surgery shows potential in orthognathic surgery, aiding surgeons to prepare and execute surgical procedures more accurately. The future studies anticipate the integration of artificial intelligence, robotic technology, and AR for further improvements in orthognathic surgery.

Le Fort I型截骨术中虚拟手术计划和增强现实固定钢板。

目的：利用计算机断层扫描（CT）成像技术在正颌手术的虚拟手术计划（VSP）中模拟手术场景，从而辅助实际手术。有多种手术策略可以提高Le Fort I型截骨术的准确性，但理想的计划和治疗方法尚未确定。本研究的目的是评估无标记增强现实（AR）的准确性，利用迭代最近点算法进行实时跟踪，无需3d打印手术导尿管、晶圆或物理标记。本研究探讨了VSP与术中无标记ar辅助系统在Le Fort I型正颌手术中的整合。方法：6例患者入组研究。我们利用包含虚拟板模型的VSP进行了无标记ar辅助正颌手术。为了评估准确性，将术后三维重建CT图像与VSP进行比较。结果：显示VSP与术后CT扫描之间距离的距离图显示上颌位置的标准偏差（SD）为0.81 mm （1mm内81.0%）。结论：该入路有利于上颌骨的移动和定位以及钛板的固定和设置。手术过程的模拟使手术过程更加直接，使我们能够以更高的精度进行实际手术。无标记ar辅助手术在正颌手术中显示出潜力，帮助外科医生更准确地准备和执行手术程序。未来的研究预计人工智能、机器人技术和AR的整合将进一步改善正颌手术。

期刊介绍： Oral & Maxillofacial Surgery founded as Mund-, Kiefer- und Gesichtschirurgie is a peer-reviewed online journal. It is designed for clinicians as well as researchers.The quarterly journal offers comprehensive coverage of new techniques, important developments and innovative ideas in oral and maxillofacial surgery and interdisciplinary aspects of cranial, facial and oral diseases and their management. The journal publishes papers of the highest scientific merit and widest possible scope on work in oral and maxillofacial surgery as well as supporting specialties. Practice-oriented articles help improve the methods used in oral and maxillofacial surgery.Every aspect of oral and maxillofacial surgery is fully covered through a range of invited review articles, clinical and research articles, technical notes, abstracts, and case reports. Specific topics are: aesthetic facial surgery, clinical pathology, computer-assisted surgery, congenital and craniofacial deformities, dentoalveolar surgery, head and neck oncology, implant dentistry, oral medicine, orthognathic surgery, reconstructive surgery, skull base surgery, TMJ and trauma.Time-limited reviewing and electronic processing allow to publish articles as fast as possible. Accepted articles are rapidly accessible online.Clinical studies submitted for publication have to include a declaration that they have been approved by an ethical committee according to the World Medical Association Declaration of Helsinki 1964 (last amendment during the 52nd World Medical Association General Assembly, Edinburgh, Scotland, October 2000). Experimental animal studies have to be carried out according to the principles of laboratory animal care (NIH publication No 86-23, revised 1985).
