This study aims to evaluate the feasibility and accuracy of 3D printing-guided endodontics in the maxillary teeth of dogs. CT data from a Beagle dog were processed to create a 3D model of the maxilla, and virtual root canal pathways were established using SOLIDWORKS software (version 29.0.0.5028). Guided endodontic templates were 3D printed and tested in vitro on 20 maxillary teeth (excluding the third molars), with 36 root canals treated using both guided and conventional methods. Results indicated that 3D printing-guided endodontics provided accurate root canal pathways, with minimal deviations in length (average 3.08 ± 1.75%) and angular alignment (average 2.06° ± 0.5°) compared to conventional methods. This research represents a significant step forward in the application of 3D printing technology in veterinary endodontics, offering a promising alternative to traditional methods for treating complex dental conditions in dogs.
本研究旨在评估3D打印引导下的牙髓治疗在犬上颌牙齿中的可行性和准确性。对一只比格犬的CT数据进行处理，以创建上颌骨的3D模型，并使用SOLIDWORKS软件（版本29.0.0.5028）建立虚拟根管路径。3D打印引导牙髓治疗模板，并在体外对20颗上颌牙齿（不包括第三磨牙）进行测试，使用引导方法和传统方法治疗36个根管。结果表明，与传统方法相比，3D打印引导下的牙髓治疗提供了准确的根管路径，长度偏差最小（平均3.08±1.75%），角度对齐偏差最小（平均2.06°±0.5°）。这项研究代表了3D打印技术在兽医牙髓治疗应用方面向前迈出的重要一步，为治疗犬类复杂牙齿疾病的传统方法提供了一种有前景的替代方案。
