Abstract:
The development of dynamic navigation system (DNS) has facilitated the development of modern digital medicine. In the field of dentistry, the cutting-edge technology is garnering widespread recognition. Based on the principles of 3-dimensional visualization, virtual design, and precise motion tracking, DNS is mainly composed of a computer, a tracking system, specialized tracer instruments, and navigation software. DNS employs a workflow that begins with preoperative data acquisition and imaging data reconstruction, followed by surgical instrument calibration and spatial registration, culminating in real-time guided operations. Currently, the system has been applied in a broad spectrum of dental procedures, encompassing dental implants, oral and maxillofacial surgery (such as tooth extraction, the treatment of maxillofacial fractures, tumors, and foreign bodies, orthognathic surgery, and temporomandibular joint ankylosis surgery), intraosseous anesthesia, and endodontic treatment (including root canal therapy and endodontic surgery). These applications benefit from its enhancements in direct visualization, treatment precision, efficiency, safety, and procedural adaptability. However, the adoption of DNS is not without substantial upfront costs, required comprehensive training, additional preparatory time, and increased radiation exposure. Despite challenges, the ongoing advancements in DNS are poised to broaden its utility and substantially strengthen digital dentistry.
摘要:
动态导航系统(DNS)的发展促进了现代数字医学的发展。在牙科领域,尖端技术正在获得广泛认可。基于三维可视化的原理,虚拟设计,和精确的运动跟踪,DNS主要由一台计算机组成,跟踪系统,专门的示踪仪器,导航软件。DNS采用从术前数据采集和成像数据重建开始的工作流程,其次是手术器械校准和空间配准,最终在实时引导操作。目前,该系统已应用于广泛的牙科手术,包括牙科植入物,口腔颌面外科(如拔牙,颌面部骨折的治疗,肿瘤,和异物,正颌手术,和颞下颌关节强直手术),骨内麻醉,和牙髓治疗(包括根管治疗和牙髓手术)。这些应用程序受益于其在直接可视化方面的增强,治疗精度,效率,安全,和程序适应性。然而,采用DNS并非没有大量的前期成本,需要全面的培训,额外的准备时间,和增加辐射暴露。尽管面临挑战,DNS的持续进步有望扩大其实用性并大大加强数字牙科。
