Over 2 ~ 3 days later, in oral buccal mucosa, can be seen scattered in small white spots.

ABSTRACT:OBJECTIVETo study the correlation between anatomic structure of the inferior alveolar nerve canal and dental implantation by measuring mandible innervation esemplarsMETHODS The intramandibular course of mandibular canal and its dimendion were measured in 15 mandibles with teeth; the relationship between blood vessel and nerve was observed in 5 fresh samples in which the artery was filled; and then the data were analyzed by statisticsRESULTSThe mandibular canal was close to the lingual side and the inferior margin of the mandible, the mandibular canal and the 10mm underside of mandible were parallel in the region of the first and the second molars, it runned outboard to genal aperture when it was hereabout genal aperture, and the blood vessel lay above nerve in the mandibular canalCONCLUSIONIn implant operation performed according to normal anatomy, injury to inferior alveolar nerve may be avoided.

［目的］探讨下颌管的解剖结构与牙种植的关系［方法］选取15具牙列完整的成人离体下颌骨标本和5具经过动脉血管内灌注的新鲜标本，测量下颌骨在每个牙位截面上有关牙槽嵴及下颌管的相关数据，进行统计学分析［结果］牙槽嵴顶以及下方10mm宽度由前向后逐渐增宽；牙槽嵴由上向下逐渐增宽；下颌管位于下颌骨体内下方走行中偏舌侧，并近下颌骨下缘，在下颌第1，2磨牙区下颌管走行与下颌下缘成平行状，在近颏孔处转向外和向颊侧出颏孔；下颌管内血管位于下牙槽神经之上［结论］牙种植术中按正常解剖部位并且侧重颊侧骨板操作，可避免损伤下牙槽神经；如果术中下颌管内突然涌出大量新鲜血液，则提示若继续手术可能损伤下牙槽神经。

Methods Ninety-five lower first molars with buccolingual vertical fracture were separated and cut vertically along the fracture line to exposure the proximal and distal residual roots. After complete pulp canal therapy,the residual roots were covered with PFM post crowns.

方法选取95例颊舌方向纵折之下颌第一磨牙病例，完全纵剖牙冠及髓室底，获得独立的近远中残根，完整的根管治疗后，行桩核和烤瓷熔附金属全冠修复，3年后进行临床评价。

If the posterior teeth or dental prostheses are missing, the cheeks may be sunken, producing a prematurely aged or cachectic appearance.

如果后牙或义齿缺失，颊部会凹陷而形成早老的或恶病质样的面貌。

If a patient does not extend the tongue far enough for the circumvallate papillae to be seen, the examiner uses a gauze pad to grasp the tip of the tongue and extend it to the desired position.

对唇部作扪诊，同时令患者张口，用舌板检查颊粘膜和口腔前庭；然后巡检硬软腭，悬雍垂和口咽部。请患者尽快地伸出舌，暴露舌背，并且尽快地向每侧移动舌，这样就可看到舌的后侧表面。

As there is no muscle or ligament present, the posterior palatal seal is placed through the centre of the deepest part of the hamular notch.

颊沟向后止于翼上颌切迹，位于上颌结节和翼钩之间，它也是基托在此区域的后界。

Judging from the improved degrees of occlusion relationship,it seems that the improvement of anterior segment is better than that of posterior segment;the improvement of intraarch relationship is better than that of interarch: the improvement of buccal relationship is better than that of lingual.

合关系的改善程度，是前牙优于后牙；牙合内优于牙合间，颊侧优于舌侧。

After obtaining the nasorbital image fitting data as the reference to the simulation and mesiodistal to different angles of the post-core angle.

图像拟合之后获取颌骨形态参数，以此为参照模拟颊舌向及近远中向不同角度的桩核冠修复角度加力后寻求安全角度范围。

Platysma flap is a viable and reliable method for lower facial reconstruction not only after malignancy ablation surgery but also for other lesions, including scar contracture after corrosive injury, post-irradiation fistula, and noma.

利用阔颈肌肉皮瓣来重建下半部颜面缺陷是个可行而且可靠的方法。不但可以用在肿瘤切除后重建，也可以用在其它方面的重建，包括腐蚀性伤害后疤痕收缩，放射线治疗后形成的瘻管，以及口颊坏疽。

Use of the pedicled buccal fat pad is a safe and easy method to reconstruct defects of the retromolar tissue.

用带蒂颊脂垫修复磨牙后区组织缺损是一种安全、简便的方法。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
