下颌前的

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)。

Objective: To quantify the new bone formation in the glenoid fossa of the temperal bone in response to the mandibular advancement.

目的：定量分析大鼠下颌持续前伸对颞下颌关节窝新骨形成的影响。

Sections were cut through the glenoid fossa at the sagittal plane and stained with PAS under the same condition.

结果：大鼠在下颌持续性前伸条件下，其颞下颌关节窝后份有明显的新骨沉积。

He has a straight front, proudly carried head, eyes gazing into the distance as if in memory of ages past. The striking characteristics of the breed-exotic, or "Eastern," expression, long silky topknot, peculiar coat pattern, very prominent hipbones, large feet, and the impression of a somewhat exaggerated bend in the stifle due to profuse trouserings-stand out clearly, giving the Afghan Hound the appearance of what he is, a king of dogs, that has held true to tradition throughout the ages.The head is of good length, showing much refinement, the skull evenly balanced with the foreface. There is a slight prominence of the nasal bone structure causing a slightly Roman appearance, the center line running up over the foreface with little or no stop, falling away in front of the eyes so there is an absolutely clear outlook with no interference; the underjaw showing great strength, the jaws long and punishing; the mouth level, meaning that the teeth from the upper jaw and lower jaw match evenly, neither overshot nor undershot.

鼻骨轻微突出的结构使它似乎具有罗马人特征，中心线沿着前颜面逐渐加宽，在眼部前方消失，所以无需推知，就可以完全精楚的知道它的外观；它的下颌显得十分有力，口部长而有力，嘴比较平，也就是说上颚的牙齿和下颌的牙齿匹配适当，上颚不突出，下颌也不突出。

OBJECTIVE: To study the effects of jaw advancement in treating micromandibular deformity associated with obstructive sleep apnea syndrome by ramus osteotomy and genioplasty.

目的观察下颌升支截骨下颌骨前徙术治疗小下颌畸形伴阻塞性睡眠呼吸暂停综合征的疗效。

Improving and routine intraoral sagittal split ramus osteotomy and advancement genioplasty were the reliable method to patient with micrognathia after arthroplasty of tempromandibular joint ankylosis.

改良下颌升支矢状劈开截骨术和常规下颌升支矢状劈开截骨术及颏水平前徙成形术，是颞颌关节强直关节成型术后小颌畸形可靠的术式。

The jaw advancement by ramus osteotomy and genioplasty for treating micromandibular deformity associated with OSAS can correct the maxillofacial deformities and enlarge the upper airway space to relieve OSAS. This method has achieved satisfactory result.

结论下颌升支截骨下颌骨前徙术治疗小下颌畸形伴OSAS，对扩张口咽通气道、解除睡眠时呼吸阻塞症状可获得较满意的效果，并同时改善了面部容貌。

In this study, we use the Computer Aided Axiography recorded condyle movement of 39 normal occlusion, during mandible open and close, protrusion and retrusion, and medio-free movement, in order to find out the normal condyle movement style and range.

本研究选用髁突轴图描记仪(Computer Aided Diagnosis Axiography)对39名正常〓的髁突运动予以记录，记录下颌在开闭口，前伸后退和侧方运动时的髁突运动情况，确立正常功能状态下双侧颞下颌关节运动形式及范围。

objectivethe aim of this study was to evaluate the curative effects of the modified fixed reverse twin-block appliance combine edgewise on treatment of adult angle ⅲ anterior crossbite.methodsthe appliance was used on 15 adult subjects with angle ⅲ malocclusion and then compared clinical character and x-ray cephalometry before and after treatment.resultsafter 4 months treatment the appearance and profile were improve evidently, mandible retrusion was to lead molar and canine were angle i,overjet and overbite were normal.

目的：应用改良固定反式双阻板矫治器（twin-block appliance，tba）联合方丝弓技术矫治成人angleⅲ前牙反牙合，为成人前牙反牙合提供新的治疗方法。方法：矫治成人患者15例，进行临床表现及相关硬组织测量。结果：固定反式tba戴用4个月后下颌明显后退。所有患者在未拔牙的情况下前牙反牙合均得到有效治疗，磨牙及尖牙均达到i类关系。但上颌仅为牙及牙槽的代偿性变化。

Then after three months patients were counterchecked.

结果： (1)可复性关节盘前移位组患者经暂时性垫治疗后，颞下颌关节紊乱指数值的改变存在统计学意义(P＜0.05)，而永久性修复3个月前后患者颞下颌关节紊乱指数值的差别无统计学意义(P＞0.05)。
