齿骨

The skeletal system showed a series of evolutive characteristics, for example, it had one premaxillary and one frontal bone, the malaris disappeared, the squamosal became smaller, the vomer became thinner, the suturae between the dentary and splenial and the suturae between the coronoid and angular was blurry.

表现出了一系列进化特征，如前颌骨愈合成1块，额骨也愈合成1块，颧骨消失，鳞骨变小，犁骨薄弱，下颌夹板骨与齿骨、冠状骨及隅骨之间的骨缝不明显，愈合程度较高。

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。

The purposes of the study were as follows:(1) to evaluate the molar furcation involvement and number of molar correlated with age and sex; and (2) to study the relationship between the means of alveolar bone loss and associated factors of molar furcation involvements.

本研究目的是：(1)探讨大臼齿根叉齿槽骨破坏、臼齿数与年龄、性别的关系；及(2)研究影响平均齿槽骨破坏量与根叉齿槽骨病变的相关因素。研究样本包括民国81年到83年6月间高雄医学院牙科219个20~65岁成人牙周病患者。

In this case, we tried to use the alveolar bone splitting technique with the Piezosurgery, and the incison line was put in the alveolar ridge as lingually as possible that the integrity of the cortical plate of the alveolar ridge is reserved in the buccal side. Because the resistance to the mesial movement of the posterior teeth is greatly decreased, the possibility of the root resorption or dehiscence is reduced, and the stability after the orthodontic treatment would be improved while the height and width of the alveolar bone increase.

本病例尝试以超音波骨刀，於缺牙区进行齿槽骨劈开手术，其切线尽可能靠近齿槽之舌侧，以使齿槽上的皮质骨板可完整置於颊侧；这样当后牙向前牵引时，才不会因皮质骨板而阻碍前进及牙根被吸收或裂开，同时也能增加齿槽骨之高度与宽度，亦可使矫正后的牙齿更加稳定。

Faculty of Dentistry is primarily dedicated to education and research in dentistry including conservative dentistry, endodontics, dental materials science, dental public health, oral and maxillofacial surgery, oral microbiology, oral pathology, cariology, oral rehabilitation, orthodontics, paediatric dentistry, periodontology, implantology.

牙科学学院创建于1980年，主要致力于牙科学的教学与研究，研究领域包括牙科保护学，牙髓学，齿骨原料科学，齿骨公共健康，口腔全颌面外科学，口腔微生物学，口腔病理学，龋病学，口腔康复，正牙学，儿科牙科学，牙周病学，移植学等。

The results indicate that both have well-developed nasals, frontal, opisthotic, and squamosal bones, but they have no orbitosphenoid, basisphenoid, pseudomesia bar, or supplemental maxilla.

研究结果表明：2种鱼均有发达的鼻骨、额骨、后耳骨和鳞片骨，上颌口缘由前颌骨构成，犁骨上具齿，上枕骨与额骨相接，左右顶骨分离，无眶蝶骨、基蝶骨、伪头中骨和辅上颌骨。

The most important factor influencing implant survival in sinus augmentation, besides individual surgical technique, is the preexisting bone height between the sinus floor and alveolar crest. The key factor for success is to achieve primary stability. When the available bone height is less than 5mm or the thickness of the cortical bone is inadequate, two stage protocol (elevating the sinus floor to create sufficient bone height first, and then placing the implant at the second stage) is a safe, predictable treatment modality.

上颚窦植牙手术的成功与否，除个人手术技巧外，常取决於剩余齿槽骨之高度(residual bone height， RBH)，如何得到初期稳定度是一重要之关键，当可利用之齿槽骨高度小於5mm或皮质骨宽度不足以支撑植体获得理想初期稳定度时，分二阶段先提高上颚窦高度再植牙，不失为一理想，安全且可预期性高之植牙方法。

This means that the alveolar bone at lingual side contributed similar effects on the mobility of incisor to that at facial side, and the effect of alveolar bone of mesial side was also similar to that at distal side.

即上颚犬齿在近心侧齿槽骨缺损与远心侧齿槽骨缺损时对牙齿动摇度的影响相当，且舌侧齿槽骨缺损对牙齿动摇度的影响和唇侧齿槽骨缺损时相同。

This means that the alveolar bone at the lingual side contributed more effect on the mobility of incisor than that of the facial side. However, the effect of alveolar bone of the mesial side was closely to the distal side.

即上颚正中门齿在近心侧齿槽骨缺损与远心侧齿槽骨缺损时对牙齿动摇度的影响相当，但舌侧齿槽骨缺损对牙齿动摇度的影响却大於唇侧齿槽骨缺损。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
