目的探讨利用Dolphin三维影像处理系统实现埋伏牙完全可视化的新技术。方法对南京医科大学附属口腔医院正畸科就诊的埋伏牙患者17例,采用锥体束颅面CT对患者头面部扫描后,将CBCT数据转化成DICOM格式保存。使用Dolphin三维影像处理技术系统,在计算机中建立三维数字牙颌面模型。结果 17例患者CBCT数据经Dolphin软件处理后,均重建出所需牙颌三维数字图像,充分显示埋伏牙的位置、结构及与周围组织关系,实现了埋伏牙充分可视化。结论 Dolphin三维影像处理技术可将CBCT信息转化成三维数字模型,快速、简便的实现埋伏牙可视化,为制定正确完善的治疗方案和外科开窗助萌操作以及有效的医患沟通提供帮助。

英文摘要：

Objective To present and discuss application of Dolphin three-dimensional image processing technology in realizing the visualization of impacted teeth. Methods Seventeen patients with impacted teeth were examined with cone beam computed tomography （ CBCT）. The CBCT data were saved as digital imaging and communications in medicine（DICOM） files. The CBCT data were input into the Dolphin software and 3-dimensional（3D） dental maxillofacial model was established on a personal computer. Results Dolphin software could translate C BCT data into 3D model and clearly showed the impacted teeth shape,the exact location,the eruption direction and the relationship with adjacent teeth and surrounding organizations. It could displace the impacted teeth with full visualization. Conclusions Dolphin three-dimensional image processing technology can translate CBCT data into 3D model,realizing the visualization of impacted teeth and it is accurate and effective in the impacted teeth diagnosis and treatment planning.
