牙列

Then, it is gradually decreased from first bicuspid to second bicuspid, first molar, which are 3.96mm, 3.62mm and 2.95mm, respectively.

上下牙列从尖牙向后，牙尖高度值和托槽粘贴高度值呈逐渐减小的趋势且依次减小约0.5mm。

The length, width, axial gradient for the crowns,the heigh of gingival line,the width of anterior dentition and the ratio of crista marginalis of their teeth were measured and analysed in their photographs and dental casts after orthodontic treatment.

测量关于正畸治疗后上颌第一前磨牙和对侧尖牙的龈缘线高度和牙齿形态的6项指标：龈缘线高度、临床冠长度、宽度、单侧前牙列宽度、轴倾度和近远中边缘嵴比，进行两均数配对t检验，观察分析两组的差异。

Three of the ten were adult denture crowded patients, the others were adults with bimaxillary protrusion. MAS mini-implant were implanted in 15, 16 and 25, 26 separately. The mini-plants were utilized with the rubber chain, ligature silk to move the cuspid to diatal and to adduct the anterior teeth.

收集武汉大学中南医院口腔正畸科就诊成人牙列重度拥挤患者3例，成人双颌前突患者3例，分别在他们15、16和25、26间各植入一枚MAS微型种植体，利用橡皮链，结扎丝和镍铬弹簧等与微植体相连牵引尖牙向远中移动、内收前牙、防止磨牙支抗丧失。

Methods: Mini-implant was used in ten cases as orthodontics anchorage. Three of the ten were adult denture crowded patients, the others were adults with bimaxillary protrusion. MAS mini-implant were implanted in 15, 16 and 25, 26 separately. The mini-plants were utilized with the rubber chain, ligature silk to move the cuspid to diatal and to adduct the anterior teeth.

Methods 40 selected patients treated with fixed appliance were randomly divided into two groups （n=20 each）, the fluoride mouth rinse test group and the placebo control group.The number of decalcified teeth and the severity of enamel decalcification were evaluated and compared after three months and after six months.

从正在接受固定正畸治疗的恒牙列患者中随机选择40例上前牙明确诊断为釉质脱矿的患者，随机分配到试验组和对照组，每组各20例，分别比较3个月后及6个月后牙釉质脱矿程度的变化。

Periodontal disease is one of chiefly reasons of dentition defect .

牙周病是造成牙列缺损的主要原因之一，牙周病缺牙的特点是缺牙两侧的余留牙也有不同程度的牙周疾患。

In all case, centric relationship of canine and 1st molar was obtained, with normal overbite and over-jet of anterior teeth.

全部病例均达到尖牙和磨牙的Ⅰ类关系、牙列整齐、前牙覆覆盖正常。

Eight pairs of twins were collected. Twin zygosity diagnosis were made by micrsatellite DNA polymorphism. The collected data included clinical oral examination and measurements of dental model. The heritability of tooth mesiodistal diameter, the length of dental arch and crowding factor were systematically analyzed.

以48对双生子作为研究对象，应用卵型鉴定技术分为单卵双生子组和二卵双生子组，采取牙牙合石膏模型并进行测量，获取牙齿近远中径大小、牙弓弧长及牙列拥挤度等数据；采用Holzinger经典双生子法计算遗传度。

The length of mandibular dental arch is controlled under weak genetic factors. Both maxillary and mandibular crowding are influenced by the environmental factors.

上下颌牙量大小和上颌牙弓弧长受较强遗传控制，下颌牙弓弧长受弱遗传控制，恒牙列拥挤度遗传度很低，受环境因素影响较大。

The dental width was normal in mixed dentition, whereas the posterior dental width was increased in adults. The dental length is decreased.

混合牙列期牙弓宽度不存在异常，而成人期后段牙弓宽度增大；牙弓长度则缩短。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
