头颅的

To avoid the influence of head position change and to overlap and compare the changing hard tissue under the skull reference system, this work set up a three-dimensional reference frame, which was based on point"S'"(the median point of the upper rear brim of the anterior wall of pituitary fossa), point"Na"and point"Ba"and of which point"S"is origin. UNISIGHT is used to get the original coordinates of all the landmarks in the MPR phase.

为消除矫治前后患者头位变化的影响，使治疗前后变化的上下颌骨和牙列以相对不变的颅底结构作为参照系统进行影像的重叠和对比，本研究通过头颅内的固有标志点S'，N，Ba三点确定了参考平面，建立了以S'点为原点的测量三维坐标系。

Objective:to provide anatomical basis of petrosal vein for operation within cellelumpontine angle.methods:the morphology,course and syntopy of petrosal vein were studied on 26 adult head specimens.results:①the number of petrosal veinswas between 1 and 3,(2.9±2.0) mm in length and (2.3±1.0) mm in diameter.

目的：为临床脑桥小脑三角区的手术提供岩静脉的应用解剖学资料。方法：应用26例经10％甲醛充分固定并灌有乳胶的国人成人头颅湿标本，手术显微镜下解剖观察岩静脉的形态、行径及其与三叉神经的毗邻关系。

The sample comprised 25 patients with the first premolar removed during orthodontic treatment. Digital models and lateral cephalometric records were taken pre- and post- treatment. We chose two kinds of regional superimposition methods on the digital models (One was the mesial zone of the third primary ruga and regional palatal vault, the other was the palate) and Baumrind's best-fit for cephalometric superimposition. The amounts of incisor and molar movement were measured and a comparative study was performed.

三。选择25例拔除上颌第一双尖牙正畸患者治疗前、后的上颌模型进行三维重建，分别使用第三腭皱近心端局部腭穹隆和腭部对同一患者治疗前、后的数字化模型进行局域重叠，以治疗前后头颅侧位片的 best-fit重叠为评价标准，比较三种方法之间的差异，对应用三维数字化牙颌模型纵向重叠评价正畸治疗前、后的牙齿移动进行探索性研究。

The using of cephalogram is limited because of the structure overlapping of the skull, jaw and teeth, for example the overlapping of the right side teeth and the left side make it difficult to distinguish the landmarks of posterior teeth.

颅颌骨牙齿之间影像的重叠使头颅定位x线片的应用受到了限制，比如牙列的重叠使后牙区的标志点难以辨认，所以对牙列的研究要借助牙〓模型。
