螺旋CT牙体表面成像技术在正畸治疗骨内埋伏牙中应用

The Application of Three-dimensional Surface Reconstruction Image of Spiral CT for Orthodontic Treatment of Impacted Teeth

目的：探讨CT在上颌埋伏牙，尤其是儿童埋伏牙诊治中的作用和应用价值。

Purpose : To study the value of CT in diagnosis and treatment of buried teeth , especially in children .

前言：目的：探讨螺旋CT三维重建技术在埋伏牙定位中的应用价值。

Objective : To discuss the Clinical application of spiral CT scanning and3D imaging reconstruction in the localization of unerupted maxillary teeth .

方法：31例（34颗）上颌埋伏牙患者进行螺旋CT检查，分别行牙体轴位、冠状位和矢状位MPR重组。

Methods : Thin slice helical CT scanning was undergone in 31 cases with buried teeth .

目的探讨螺旋CT最大密度投影（MIP）对上颌埋伏牙定位的应用价值。

Objective To study the applied value of SCT MIP in the localization of maxillary impacted teeth .

结果螺旋CT扫描及三维重建能清晰显示复杂的颌骨解剖图像以及骨埋伏牙与周围结构的关系。

Results the positions of wholly impacted supernumerary teeth in the complex maxilla or mandible anatomy structure images were clear reflected by SCT scan and 3D reconstruction .

结果：根据CT各种图像特点，对上颌埋伏牙从数目、解剖位置、三维相邻关系几方面进行了较为系统的分类。

These images were compared with traditional X - ray films . Results : Based on various CT images , we classified maxillary buried teeth systematically by number , anatomical position and 3D relationship .

材料和方法：41例牙齿正畸的患者行螺旋CT轴位扫描，其中上颌埋伏牙20例，男13例，女7例。年龄8～18岁，平均12.5岁。

Materials and Methods : Helical CT was performed in 20 patients with buried teeth in maxilla , including 13 males and 7 females , aging from 8 ~ 18 ( mean 12.5 ) years .

结果4种重建图像中，MIP图像对上颌埋伏牙定位的显示率最高，对埋伏内部结构的密度差异显示最好。

Results Of the four techniques , MIP had the highest displaying rate and was the best in displaying inner density difference of impacted teeth .

结果MPR可提供埋伏牙所处部位骨组织的相对密度，精确测量埋伏牙各个解剖位置与颊舌向骨壁或邻牙间的距离；

Results MPR was able to demonstrate the relative bone intensity around the implanted tooth and exactly determine the distance of impacted tooth with the buccolingual bone wall or adjacent teeth .

结果经CT三维重建和SSD处理后，20例病例均清楚地显示了埋伏牙的牙体形态、唇腭向位置、萌出方向以及与邻牙的关系。

Results Three_dimensional surface reconstruction of spiral CT and SSD could clearly demonstrate the dental surface image including crown , root neck and root bifurcation in three_dimensional way , labial or palatal location , eruption orientation and relation with dentition .

横向断层P23程序在颌骨前牙区埋伏牙定位中的应用

The Application of the 23rd Program of Transverse Panoramic Tomographs in the Orientation of the Unerupted Premaxillary Teeth

MIP清楚显示牙齿全貌、牙齿纵向排列关系，显示颌骨内埋伏牙36颗，通过旋转角度显示埋伏牙位置、形态，其中位于牙列的腭侧29颗，唇侧7颗。

MIP clearly manifested the full view and the longitudinal alignment of the teeth . Among the 36 buried teeth , there were 29 palatally and 7 labially presented teeth , and they were morphologically delineated on MIP through various angles .
