Tooth agenesis is a common tooth dysplasia.

先天缺牙是比较常见的牙齿发育异常疾病。

In this case, we tried to use the alveolar bone splitting technique with the Piezosurgery, and the incison line was put in the alveolar ridge as lingually as possible that the integrity of the cortical plate of the alveolar ridge is reserved in the buccal side. Because the resistance to the mesial movement of the posterior teeth is greatly decreased, the possibility of the root resorption or dehiscence is reduced, and the stability after the orthodontic treatment would be improved while the height and width of the alveolar bone increase.

本病例尝试以超音波骨刀，於缺牙区进行齿槽骨劈开手术，其切线尽可能靠近齿槽之舌侧，以使齿槽上的皮质骨板可完整置於颊侧；这样当后牙向前牵引时，才不会因皮质骨板而阻碍前进及牙根被吸收或裂开，同时也能增加齿槽骨之高度与宽度，亦可使矫正后的牙齿更加稳定。

Objective: To find clinical solution of maxilla posterior undentition without enough bone for implantation.

目的：解决上颌后牙缺牙区因骨量不足无法种植修复的临床问题。

If the child's permanent teeth after injuries, tooth injuries completely fell down, if not handled properly at this time would lead to life-long missing and should therefore be calm, back off the teeth.

如果宝宝的恒牙受伤后，受伤的牙齿完全掉了下来，这时如果处理不当便会导致终身缺牙，因此应当保持平静，找回脱落的牙齿。

Result These patients can have occlusal real relationships and recovery the losing anterior teeth .After one year, recurrence and unusualness haven't been found.

结果 矫治后均取得正常的咬合关系和正常的缺牙修复，平均修复一年，未见反复发和修复牙的异常。

An atomatic modeling program is developed to establish the parameterized finite element model of such joints with damaged teed, the elastoplastic contact characteristics and stress-strain of threaded tubing joists are analyzed by the software of ANSYS.

开发了存在螺牙损伤的油管螺纹接头参数化有限元自动建模程序，应用ANSYS软件对缺牙油管螺纹接头进行了弹塑性接触特性及应力应变分析。

Measurements of the longitudinalseparation, buccolingual space and highness of the area were established to select the perfect spiral-shafted implant and simulating the implant. by means of the process the dentists can know about the complications well that may happen or not and know how to do the work wonderfully.

选择一例男性、55岁、右下第一磨牙缺失的患者，螺旋CT扫描， DICOM格式数据储存，应用OINS软件进行读取和分析，对缺牙区的前后径、颊舌径和所需高度进行测量，根据所得的数据并结合需要选择合适的种植钉，模拟种植。

This simplified method combined with crown lengthening procedure and occlusal rehabilitation, the problems of insufficient interarch space and gummy smile were resolved without neither orthodontic treatment nor alteration of the occlusal vertical dimension.

本病例报告为一女性患者因长期局部缺牙，因而丧失赝复空间，在不改变其咬合垂直高度为前提下，施行上颚半口及下颚后牙之牙冠增长术，并提高其咬合平面，最后上颚以固定式局部义齿、下颚以固定式义齿合并植牙来赝复，赝复空间不足的问题已解决，病人微笑时过多牙龈暴露的情形也获得改善。

Loaded on the pontic vertically, the distribution of the stresses in periodontal ligament was less un...

提示粘接桥修复时更应充分考虑基牙条件，缺牙区间隙的大小及修复材料的选择。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
