Other diagnostic features include the presence of a crest along the anterodorsal midlines of the premaxillae,the edentulous maxilla,the presence of a groove-like trough along with the anterolateral margin of the maxilla on the ventral surface,the presence of six conical premaxillary teeth,and no more than six conical dentary teeth which are restricted to the anterior portion of the dentary.

其他主要特征有：前颌骨沿前背中央有一隆嵴；上颌仅前颌骨有6枚圆锥形齿，无上颌骨齿；上颌骨沿前腹侧缘有一沟槽；下颌齿骨齿都集中在前端且至多不超过6枚。依据上述这些特征很易把短吻贫齿龙与其他已知海龙相区别。短吻贫齿龙头骨顶面松果孔大且很前位，头骨腭面的锄骨和翼骨均无齿，它的颈较长(至少可以辨认出13个颈椎)。

The diagnostic features for the species include deep excavation on the posteroventral margin of the premaxilla, a diastema between the premaxillary and maxillary teeth, a a number of many pits and ridges on the anterolateral surface of the antorbital fossa, the posterolateral process of the parietal being long and sharply posteriorly directed, the column ar -like margin of the pterygoid process of the quadrate, the bifurcated posterior margin of the dentary, a distinctive groove posterior to the anterior carina on the medial surface of the premaxillary tooth crowns, absence of ventrolateral processes on intercentrum of t he atlas, T-shaped centrum of the first caudal in ventral view, transverse process on anterior caudals with rounded , and strongly anteroposteriorly expanded distal end, presence of two fossae separated by an oblique ridge on the lateral side of the anterior chevrons near the articular end, and pubis strongly curved psoteriorly.

这一属种的主要鉴定特征包括：前上颌骨后腹缘有一深凹、前上颌齿和上颌齿之间有一齿缺、眶前窝外表面前部有许多坑窝和脊、顶骨侧后突伸向后方、方骨的翼骨支边缘柱状、靠近前上颌齿齿冠舌面前缘有槽、环椎间椎体外腹突缺失、第一尾椎椎体腹视 T 形、前部尾椎横突远端前后向强烈扩展呈圆形、前部脉弧近端外侧面有两个被一斜脊分离的窝以及耻骨强烈向后弯曲。通过分析千禧中国鸟龙的96个骨骼学特征，发现其中21个特征支持奔龙类与鸟类的亲缘关系最近，9个特征支持奔龙类与伤齿龙类亲缘关系最近，25个特征支持奔龙类、伤齿龙类和鸟类亲缘关系较为接近。

In this research, the pubertal five-week-old SD rats were chose as experimental object to establish the animal model for simulating maxillary protraction, on which was imposed the orthopedic force of 85g with utilizing the self-devised maxillary protraction appliance. Located lateral X-ray cephalograms were taken to measure and analyze the changes of maxillary development after exerting the orthopedic force for 4 weeks. The technique of immunohistochemistry was used to investigate theexpression of TGF-, in frontomaxillary sutures and palatomaxillary sutures with identical force performing for different extent of time. The average hue was selected as indicator, which was measured by the means of the analysis system of pathological color images. The measuring data were analyzed by the one-way ANOVA in software SPSS 11.0 version.

本研究采用自行设计的上颌前牵引装置，以生长发育期5周龄SD大鼠为实验对象，施加85g的矫形力，建立了模拟上颌前牵引的动物模型，通过X线头影测量分析，观察施力4周后上颌骨的生长发育情况；应用免疫组织化学技术，检测同一力值作用不同时段下TGF-β_1在上颌骨的额颌缝、腭颌缝的表达，彩色病理图象分析系统测定每张切片中阳性染色细胞的平均灰度值，结果采用SPSS 11.0进行方差分析。

Careful treatment can decrease the complication rate. 3. Three-dimensional finite element model analysis showed that zygomaticoalveolar crest is the major site sustaining stress, which indicated that the fixation of zygomaticoalveolar crest should be strengthened, if there is some space between zygomaticoalveolar crest and fibula bone, free bone graft can fill the space to rebuild the bony zygomatic process support.

游离腓骨复合组织瓣上颌骨重建的三维有限元分析表明，颧牙槽嵴部位是腓骨瓣上颌骨重建后咀嚼压力的主要受力部位，提示腓骨瓣上颌骨重建时要加强颧牙槽嵴的固定；当上颌骨切除后腓骨与颧牙槽嵴存在间隙时，应尽量采取游离骨块移植，充填间隙，重建骨性颧突支柱。
