摘　　要：目的:探讨三维重建可视化技术在埋伏牙拔除术前定位和设计中的应用价值。方法:以2017-12-2018-12期间收治的97例埋伏牙患者为研究对象,术前拍摄CBCT,将数据以DICOM格式导入Simplant Pro 11.0软件,构建颌骨和牙列的三维可视化模型,对埋伏牙进行定位分析,观察其与邻近解剖结构的关系,设计拔牙方案。手术方案确定后,在全麻下按照术前计划实施拔牙手术。结果:97例患者共123颗埋伏牙均按照术前设计的方案顺利拔除,无1例在术中改变手术方案。所有患者均未发生神经损伤、上颌窦或鼻底穿通、邻牙损伤、异常出血等并发症。结论:三维重建可视化技术有助于埋伏牙的精确定位和拔牙方案的术前设计,值得临床推广。Objective: To study the application value of three-dimensional reconstruction visualization technique in preoperative locating and surgical planning of embedded teeth removal. Methods: In total 97 patients with embedded teeth admitted between December 2017 and December 2018 were enrolled. CBCT was taken preoperatively and data in DICOM format was imported into Simplant Pro 11.0 software to construct a three-dimensional visualization model of the jaw and dentition. The positioning analysis of the impacted teeth was carried out to observe the adjacent relationship of the surrounding anatomical structures. And the surgical extraction plan was designed based on this three-dimensional visualization model. After the surgical plan was determined, the extraction operation was performed under general anesthesia according to the preoperative plan. Results: One hundred and twenty three embedded teeth in 97 patients were successfully removed according to the original preoperative surgical plan. None of the patients had complications such as nerve injury,maxillary sinus or nasal perforation, adjacent teeth injury, or abnormal bleeding. Conclusion: The three-dimensional reconstruction visualization technology is helpful for accurately locating the embedded teeth and optimizing surgical extraction plan, which is worthy of popularization in clinical practice.
