Guided endodontics represents an effective method for achieving safe and reliable endodontic surgery in human medicine. However, it is rarely employed in small animal dentistry. This study employed finite element analysis and three-dimensional (3D) printing techniques to explore the feasibility of guided endodontics in Beagle mandibular teeth.
The methodology included the processing of Computed Tomography (CT) data, the creation of mathematical and 3D printing templates of the root canal pathways, and the evaluation of dog 3D printing guided endodontics compared with classic root canal method using radiograph.
In this experiment, the coordinates of the central point of pulp crown and apex point for each tooth were recorded. Based on the extension line of the central point of dental root canal orifice and the apex point, guided endodontic templates were designed on each root canal of 20 teeth in the Beagle mandible. Among them, the average relative deviation of guided endodontics and classic root canal method was 4.28% ± 2.75%, and the mean angular deviation was 1.90 ± 0.25°.
Our research indicated that dog 3D printing guided endodontics has accurate position, direction, and length, which may assist veterinary dentistry in root canal treatment in small animals.
引导式牙髓治疗是一种在人类医学中实现安全可靠牙髓手术的有效方法。然而，它在小动物牙科中很少使用。本研究采用有限元分析和三维（3D）打印技术，探讨引导式牙髓治疗在比格犬下颌牙齿中的可行性。
该方法包括计算机断层扫描（CT）数据处理、根管通路的数学和3D打印模板创建，以及使用X射线照片将犬3D打印引导式牙髓治疗与经典根管方法进行比较评估。
在本实验中，记录了每颗牙齿牙髓冠中心点和根尖点的坐标。基于根管口中心点和根尖点的延长线，在比格犬下颌20颗牙齿的每个根管上设计了引导式牙髓治疗模板。其中，引导式牙髓治疗与经典根管方法的平均相对偏差为4.28%±2.75%，平均角度偏差为1.90±0.25°。
我们的研究表明，犬3D打印引导式牙髓治疗具有准确的位置、方向和长度，这可能有助于兽医牙科对小动物进行根管治疗。
