无牙

Since the machine speed fast, the strength of the avulsing, the drum in particular for the imprint of the drum and carry it and carry it to remain in force General 16kg than radiograph, clishion always maintained in a clean, open and closed freely, in a pipe pressure, wearless, teeth-axis in the spring of elastic to a value greater than the small spring force in its teeth.

由于机不缓迟，不粘贴辛不小，各滚筒不入格是不抬印滚筒叼牙的叼辛凡是给保留在16kg以上，且牙片、牙垫本末给保留肮脏、开闭自若，处于叼辛陡均、无磨损的精良状况，牙轴边的扭簧的弹辛给不小于各叼牙小弹簧辛的总和。

The first three largest number of missing teeth is as follows: maxillary first molar, maxillary second molar and mandibular first molar. The first three largest number of resident teeth is as follows: mandibular cuspid, mandibular bicuspid and maxillary cuspid. The cases without occusal relationship account for 19.51%; and the cases which need occlusal reconstruction or occlusal elevation account for 19.51% of all the cases, while food impaction exists in 21.84% cases.

结果：本组老年人平均缺失牙齿9.10颗，缺失最多的前3位牙齿是上颌第一磨牙、上颌第二磨牙和下颌第一磨牙；余留最多的前3位牙齿是下颌尖牙、下颌第一双尖牙和上颌尖牙。19.51%的病例颌骨间无咬合接触关系，19.51%的病例修复时需咬合重建或咬合抬高；21.84%的病例修复前存在食物嵌塞。

Results: Among the 47 cases, 33 cases were teeth pulpless tissue including 14 endodentically treated teeth and 14 cases were vital teeth with periodontitis, cracked tooth and occlusal traumatism.

结果：牙冠纵折多见后牙，以上颌第一磨牙为多见，其中无髓牙33例，牙折裂前有近一半曾作过根管治疗，活髓牙14例，存在不同程度的牙隐裂，牙周炎和咬合创伤。

The longest time was 22 months.the shortest time was 12 months. Conclusion The extraction planing of missing the first molars in class Ⅰmalocclusion is different from routine extraction mode.This clinical study indicated that it should chose nimble planing and for decurtate treatment time,according to arch crowding, profile and existing of the third molars.

第一磨牙缺失的患者在I类错牙合畸形中的拔牙模式有别于常规，要根据患者牙弓的拥挤程度，面型突度及有无第三磨牙等情况选择治疗计划和有利于缩短疗程的矫治方法。

Non-occluding teeth with a hypofunctional periodontium have a lower rate of bone remodeling, and are more susceptible to the injury in periodontal tissues caused by orthodontic force than normally occluding teeth, such as hyalinization or undermining bone resorption, even dentin resorption.

正畸治疗中，无咬合接触的牙周膜废用性萎缩牙较正常咬合接触牙对矫治力反应差，骨改建率低，易发生玻璃样变和潜掘性骨吸收，延缓牙移动，因此对无咬合接触牙的临床治疗中应采用轻力。

Results Compared with T1, statistically significant increases were recorded in all dentoalveolar and dental arch widths, except for the intermolar width measured fossa, and also arch perimeter at T2 (P＜0.05). No significant changes were found in the arch depth.

结果 与T1阶段相比，T2阶段除了磨牙中央窝点间牙弓宽度测量项目外，所有牙槽弓、牙弓宽度测量值以及牙弓周长测量值均显著增大（P＜0.05），但牙弓长度的变化无统计学意义。

Methods: The sample consisted143 children which were in early permanent dentition of ClassⅡ,Division 1malocclusion .Pre-and post-treatment study models were assessed using PeerAssessment Rating index. According to the outcome of treatment, thesecases were classified into three types as "worse, no different","improved"and"greatly improved". The cephalometric analysis and Model Analysis werepreformed with pretreatment lateral cephalograms and study models for"improved"and "greatly improved"cases."T"–test was assessed to find out thesignificant difference between the extraction and nonextraction, and the resultsincluding age factor were analyzed by stepwise discriminant analysis.

应用PAR 指数对矫治前后的143 副恒牙早期的安氏Ⅱ类1 分类错牙合患者牙牙合模型进行评估分析，按矫治结果等级分为三类A、变坏或无改善，B、改善，C、极大改善，然后将B、C 两类患者矫治前的头影测量片及模型分析数据按拔牙与未拔牙进行成组t 检验的单因素分析，找出两组间有显著差异的软硬组织和牙牙合模型指标，对这些指标合并年龄因素进行逐步判别分析。

Nano-imprint lithography drum paper teeth axis, swayig begnawing workparts paper teeth or wear, allows unleashmy begnawing paper teeth in paper in an inconsistent state in that result in bilateral irregular longitudinal misregister, in which case on slow computers are more likely to occur, because the impact of low-speed machine tipping bucket, the strength of a rotational motion paper teeth ranges of swayig high speed machine is used, and indirect sheet transfer unleashmy simpleplan paper teeth have smaller, at the same time as a result of automatic circulation lubrication oil system, unleashmy and apparatdus paper teeth axis is not easy to wear, but bearing in mind that oil, oilway jam torn oil grinding.

压印滚筒咬纸牙轴，摆动咬纸牙轴或轴套磨损后，不离使得咬纸牙在咬纸功程洋处于不稳不退状况，以至于爆发双边无次序的纵向套印禁绝，这栽环境在不低速机上比辛便当呈现，因为不低速机翻斗撞击辛不小，咬纸牙轴动弹幅度比辛不小，不低速机是拔取摆动不直接递纸，并且咬纸牙闭合幅度也较小，同时又由于有被迫轮回油路编制润滑，所以咬纸牙轴及轴套不便当磨损，但给夺目油眼，油路畅通导致不续油咬不松。

Maxillary central incisors had a slightly greater pulpal blood flow values than maxillary lateral incisors. The flow values from 15 teeth with necrotic pulp or pulpless teeth were significantly lower than that from the control teeth. Before therapy the values from 16 deep caries teeth were all higher than that from the control teeth. After therapy, most (15/16) of those values decreased to normal in three days. The value of one tooth with deep caries remained high, and one week later, the pulp became necrosis.

由死髓牙测得的流量值显著小于正常对照。16颗深龋患牙治疗前牙髓血流量皆高于正常对照组，治疗后有15颗患牙的血流量很快降至正常，有1颗患牙在治疗后血流量无明显变化，最终发生牙髓坏死。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
