Congenital missing tooth can be divided into hypodontia、oligodontia and anodontia. Oligodontia is defined as absence of six or more teeth.

先天缺牙可分为个别牙先天缺失、多数牙先天缺失和先天无牙症三种类型。

Objective:To observe the differences of bone mineral density of mandible and coxofemoral region between well-rounded ridge group and atrophied ridge group in edentulous patients,and to find the risk factors contributing to severe residual ridge resorption.

目的：观察无牙颌患者剩余牙槽嵴丰满组与非丰满组间下颌骨和髋部骨密度的差别；探讨导致严重剩余牙槽嵴吸收的危险因素。

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。

Company main product includes: cutting teeth oblique films, straight teeth Cutting tablets, cutting tablets toothless, Mopan, such as electroplating.

应用经颅彩色多谱勒超声扫描仪(Transcranial Color Doppler ，TCCD)探测牙列完整受试者及无牙颌患者在安静状态下和咀嚼无糖口香糖10分钟后脑血流速的改变，对大脑中动脉收缩期峰流速(systolic peak flow velocity ，Vs)、舒张期末峰流速(enddiastolic peak flow velocity ，Vd)、平均峰流速(mean peak flow velocity ，Vm)进行统计分析。

Of resorption in vertical and horizontal direction.The purpose of this article is to get the average values and standard deviation of the alveolar ridge heights of the upper and lower central incisors and the first permanent molors in adult with normal occlusion by cep...

测量正常成年人60名的结果提示利用新定的标志和线距对无牙颌原有的上下中切牙和第一磨牙的位置有了确定的方法和数据，进而可测得无牙颌牙槽骨的吸收量，因而扩大了头影测量的临床应用范围。
