咬合

The maximum velocity of the mouth opening and closing while chewing was increased significantly, the maximum velocity position was displaced inferiorly, and the average velocity was also increased during the bite-corrected to the stable occlusion established.

总结即是在咬合的型态改正之后，会立即性地影响咀嚼的功能，所评估众多参数当中，最明显的就是咀嚼的速度会明显增加。

Their different part of denture were ground artificially to establish an animal model of infraocclusion.

采用人工磨低大鼠不同牙列段牙齿的方法建立低位咬合动物模型，于干预后1，2，4wk后将各组分别处死大鼠4只。

For cases with insufficient interarch space, the preprosthetic treatment planning and cast analysis are the key elements of success.

此方法单纯以牙冠增长术来解决空间问题，而不改变其咬合垂直高度，也省却矫正的疗程，但是术前详细的检查与诊断模型分析是很重要的。

From a preventive and interceptive viewpoint, when a child's dentition is a Class I relationship before the primary second molars are lost, so that the space derived from mesial drift and diastemata is available, it is likely that emerging permanent teeth will assume correct alignment.

由预防性与阻断性的观点而言，当小病人在第二乳臼齿脱落之前的齿列是一级咬合关系时，如此空间可由近心倾斜门齿间隙所获得，而将来的永久齿是可得一正确的排列。

The molars intermesh properly. The bite is a true scissors bite.

臼齿互相啮合，牢固对称，呈剪刀式咬合。

No malunion, delayed healing and pseudarthrosis was present in this series.

治疗组出现3例咬合关系不良，占5.36%；对照组出现12例，占21.43%，两组比较差异显著(P.05)。

结论bFGF参与了大鼠渐进性咬合紊乱所致髁突软骨的改建活动。

A small and gradually TW was a physiological process accompanied by ones all life, but severe TW could cause a series of pathological changes between tooth and dentition, occlusion and articulation, the maxillomandibular relation and masticatory muscles. TW can affect the healthy between mastication and all correlated tissue.

少量的、逐渐的牙齿磨耗是伴随一生的生理过程，而重度磨耗可以引起牙与牙列、与咬合、颌间关系与颌周肌肉、颞下颌关节等发生一系列病理变化，从而影响到咀嚼功能和各相关组织的健康。

A case report was presented with a female patient of class II malocclusion, bimaxillary dentoalveolar protrusion with space deficiency. Bilateral lower left second molars were mesially inclined impactions with large caries. The lower left second molar was diagnosed with acute apical periodontitis.

本文提出一双颚齿槽前突合并齿列拥挤之安格氏二级咬合不正之女性患者，其下颚两侧第二大臼齿为近心倾倒之阻生齿合并龋齿，而左下第二大臼齿之龋齿已侵犯到牙髓而有急性根尖牙周炎的情况。

Both upper and lower dental study models were collected from 30 boys (12 years old) and 30 girls (12 years old) with acceptable normal occlusion to understand the characteristics of the crown size, dental arch width and length such as (1) mesiodistal diameters of crown size from central incisor to first molar,(2) the width and length of dental arch and basal arch and (3) the morphology of dental arch form. After statistical analysis, data were compared with Japanese, Central and South American Indians and North American Caucasians from papers. The results were:(1) There was no statistical difference in teeth size between males and females, except the upper first molar of males was larger than that of females, lower central incisor of males was smaller than that of females.(2) The dimensions of dental arch of males were larger than that of females in general, especially such items as width and length of basal arch.(3) The crown size of Chinese male was in generally smaller than that of four other races, especially the upper canine, lower central incisor and first molar.

为了解住在台湾的中国人其牙齿的大小，齿列弓幅径及形态，为齿科人类学上的特微，以期能对儿童牙科，齿颚矫正科之临床及齿科基础医学能有所贡献，抽取12岁学童男女各30名共60名，可接受为正常咬合之上下颚齿列模型，测量其上下颚(1)左侧正中门牙到第一大臼齿共计12颗恒牙之牙冠近远心径，(2)齿列弓宽径、长径及齿槽基底宽径、长径，(3)齿列弓之形态，以上资料经统计分析作t-test检定，并与诸学者对日本人、北美白人、中美及南美印第安人人种的研究结果作检讨得知；(1)男女性恒牙的近远心径无明显差异，但男性上颚第大臼齿比女性者大，下颚正中门牙比女性者小；(2)男性的齿列弓幅径比女性者为大，尤以齿槽基底宽径及长径最显著；(3)国人男子的牙齿近远心径比其他四人种者为小，特别是国人的上颚犬齿，下颚正中门牙及第一大臼齿最小。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
