摘　　要：目的对埋伏牙进行影像学分类,以便临床上对埋伏牙作进一步定位和为手术进路提供参考和指导。方法采用回顾性分析的方法,对近期门诊收治的82例患者106颗埋伏牙的颌骨曲面断层片进行再研究,并对其临床检查结果和术式等临床资料进行归纳总结。在颌骨牙列X射线曲面断层片的基础上自定义根尖曲线并进行分类。结果将埋伏牙分为3类,其中Ⅰ类16颗,Ⅱ类54颗,Ⅲ类36颗。结论该分类方法能为埋伏阻生牙的精确定位和手术进路提供临床指导。Objective To conduct the imageological classification of impacted teeth to perform the accurate orientation and provide the reference and guidance for the operative approach in clinic. Methods By the rretrospecdvc analysis,the panoramic images of 106 teeth in 82 outpatients were performed the restudy. Their clinical detection results and the clinical data including the operative patterns were summarized. Based on X-ray panoramic images of jawbone dentition, the root tip curve was determined by self-defining and the classification was conducted. Results The impacted teeth were divided into three types, including 16 teeth in the type I ,54 teeth in the type II and 36 teeth in the typeIII. Conclusion This classification can provide the clinical guidance for the accurate orientation and the operation approach of impacted teeth in clinic.
