All the patients had acquired normal overbite and overjet relationship, and the upper and lower dentitions had got coordinate Bolton exponents.

所有患者均获得正常覆牙合、覆盖关系，上下牙列Bolton指数协调。

Periodontal disease is one of the most common disease in oral cavity, which is the reason of defect of dentition second only than dental caries. It results in junctional epithelium turn root periodontal pocket emerge, tooth mobility, aversion and amotic. Among the total, the alveolar bone shrikes to root can not reversible.

牙周病是口腔常见病之一，是仅次于龋病导致牙列缺损的第二大原因，造成结合上皮根向迁移、牙周袋形成、牙齿松动、移位和脱落等病理改变，其中牙槽骨向根方的退缩是不可逆的。

Results: 1 Upper first molars and first premolars moved approximately in the same style.

观测10例恒牙早期患者在快速扩弓前后上颌牙列齐标志点间的位置和角度改变。

Methods 37patients with complicated dentition defect that can't use traditional removable partial denture were involved in the study.

选择37例因传统可摘局部义齿无法戴用或对此类修复体效果不满意的复杂牙列缺损患者，附着体义齿修复前首先请患者对现有可摘局部义齿就咀嚼功能恢复、舒适度、发音与美观3个主观项目进行评价，其次由修复科医师对义齿的固位情况、对基牙的影响、对口腔卫生的影响3项客观指标进行评价，并在附着体义齿修复后1～5年再对上述6项指标进行评价。

They will pull out the double sharp tooth of its behind 1, please tiger tooth to return to go in the tooth row under the function in the being in conjunction with of lips cheek muscle.

他们会将它后面的双尖牙拔掉一颗，在唇颊肌肉的协同作用下，把虎牙请回到牙列中去。

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。
