牙骨

The columella was nonsurgically lengthened from 1.13mm to 3.78mm (P.05). CONCLUSION: In order to obtain satisfactory lip-nose configuration for BCLP, presurgical NAM is useful in cleft lip and palate team approach.

双侧完全性唇腭裂患儿为了获得较为理想的鼻唇形态及牙槽骨的规则弧形排列，术前鼻－牙槽骨塑形是值得采用的序列治疗方法。

The measurement covered the tooth material,premolar diametre,premolar basal arch widthand basal arch length. The ratios of PMD/TM, PMBAW/TM and BAL/TM were calculate.

测量牙量、双尖牙弓宽径、双尖牙根尖基骨宽径、基骨弓长度，并计算PMD/TM、PMBAW/TM、BAL/TM值，对其进行统计学处理与分析。

Methods: 23 patients(17 females and 6 males;mean age 12.70±1.89 years) with narrow upper arch were treated with Hyrax appliances and received CBCT scans pre-and after RPE treatment.

所有患者经Hyrax扩弓治疗，治疗前后采用CBCT技术采集并重建双侧P2区的三维结构，测量牙齿、牙槽嵴和颌骨不同平面的宽度以及牙齿、牙槽嵴与腭骨的相关角度，然后进行配对样本t检验。

All the patients with 8-11 mm height of residual bone in the posterior maxilla underwent sinus floor elevation and implant placement using osteotome without any bone grafts simultaneously.

患者均因上颌后牙种植区牙槽嵴顶至上颌窦底之间的剩余骨高度在8～11mm，无法植入足够长度的种植体，因而采用上颌窦底冲压法局部提升上颌窦底骨板及黏骨膜，提升幅度为2～5mm。

For each subject, the buccolingual bone thickness was measured by postulating that the miniscrews would be inserted at 16 positions (10, 12, 14 and 16 mm above the median sagittal planes of the interradicular spaces between the first molars and the second premolars in the maxilla, and 30°, 45°, 60°, 90° from the cortical bone surface).

在重建后的锥形线束CT影像上测量上颌第二前磨牙与第一磨牙牙根间矢状面上距离参考平面10，12，14，16 mm的4个植入高度上，以与骨皮质表面成30°，45°，60°，90°的4个方向共16个部位的颊舌侧骨质厚度，计算各植入部位触及上颌窦的危险率，在骨厚度大于6 mm的植入部位模拟植入微螺钉种植体并测量其周围骨质密度。

Apoptosis was not detected in osteoblasts,osteoclasts and hyalinization in this study.

牙齿移动时，压力侧牙槽骨改建活跃，凋亡细胞有增多趋势，而张力侧牙槽骨凋亡细胞呈减少趋势。

Results: Immunohistochemical staining revealed that expression of RANKL protein was detected in periodontal ligament cells and osteoclasts which mostly located in resorption lacunae.

结果：正畸牙移动压力侧组化结果显示，RANKL阳性表达位于牙周膜细胞和位于骨陷窝内的破骨细胞中，在正畸牙移动第3、5和7天时呈强阳性表达。

The fluorescent bands formed in both mesial and distal cementum.Conclusion The results don't support the point that transseptal fibre or force of molar eruption makes teeth migrate mesially; the mesial migration of teeth is related with the reconstruction of alveolar bones and the stress distribution in the bones.

实验结果不支持越隔纤维作用或磨牙萌出力作用引起牙齿近中移动的观点；牙齿近中移动与颌骨内应力分布有关，牙槽骨改建的量与牙齿近中移动量呈正相关。

In the peacetime, the bactria results in of the chronic infection will make gum inflammation, easily bloodshed, palatine bone absorption, decayed tooth and toothache, end because dens turnover get sick of tooth loose move or dens neurapophysis necrosis and pull out a tooth, next door usefully the second molar teeth be usually also subjected to spread and result in at this time the injury of waiting the degree even pull out a tooth not, this is also the most regrettable place.

在平时，细菌造成的慢性感染会使牙龈发炎，容易流血，骨吸收，蛀牙及牙痛，最后因牙周病的牙齿松动或牙髓坏死而拔牙，这时隔壁有用的第二大臼齿往往也会受到波及而造成不等程度的伤害，甚至拔牙，这也是最可惜的地方。

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。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
