查询词典 edentulous

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)。

Results: The deviation and stress distribution of the edentulous jaws and the base plates were obtained.

结果：得出了七种模型的基托及无牙颌骨的位移及应力分布值。

Objective: To investigate the influence of the different angles of the occlusal plane on the supporting tissues of the edentulous jaws.

目的：研究全口义齿不同倾斜角度的平面对无牙颌支持组织受力的影响。

Changes in the vertical distance produce different effects of stress on edentulous jaw under the same load.

Objective: To discuss how some individual factors of edentulous patients influence on the appearance of complete dentures.

随着生活水平的提高，人们在满足基本生活需要后，自然要追求更高层次的美观需要。

Objective To evaluate the application effect of the ball attachment implant denture in the edentulous jaws.

目的：探讨球状附着式种植义齿在无牙颌中的应用效果。

Objective To explore the force system of different precision attachments in mandible distal-extension edentulous by a finite-element model.

目的 探讨按扣式和键槽缓压式两种精密附着体修复下颌磨牙游离缺失的应力分布情况。

Methods:20 edentulous patients with poor condition of alveolar ridge failed in treating with complete denture.

Objective To analyse the stress distribution of precision attachment dentures used in distal-extension edentulous cases.

目的 对精密附着体义齿修复末端游离缺失的应力分布情况进行有限元分析。

Methods:The edentulous patients of senile males and postmenopausal females were selected.All the edentulous subjects were divided into two groups according to the degree of RRR of mandibles: well-rounded ridge group and atrophied ridge group; The BMD of mandibular angle and coxofemoral region (femoral neck,trochanter,and wards triangle) of all subjects were measured by dual energy X-ray absorptiometry.The BMD were compared between well-rounded ridge group and atrophied ridge group in the same sex group.

将60岁以上男性和绝经后女性无牙颌患者依据下颌剩余牙槽嵴吸收程度分为丰满组和非丰满组；采用双能X线吸收法，测量全部研究对象右侧髋部与左侧下颌角的骨密度；在同性别组内对比丰满组和非丰满组间下颌角和髋部骨密度的差别。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
