Results:In normal occlusion,the size of cuspid and bicuspid group was correlated with that of mandibular incisor group in accord with the principle of Moyers prediction.
结果：正常的尖牙、双尖牙组与下切牙组高度相关，符合Moyers预测机理，但错的尖牙、双尖牙组一般与同牙列的切牙加第一磨牙组高度正相关。

METHODS: Measurement of palatal raphe area first three-dimensional reconstruction of images at up to nasion plane centerline, whichever was determined as a reference surface plane, selection one point on incisor cervix in this line, to measurement of the available palatal bone height; sagittal views were selected at 6 mm dorsally from the incisive canal. The available bone height was defined as the distance from the palatal baseline (lower cortical border of the palate) to the nasal cavity (upper cortical border of the nasal cavity).
先在三维重建图像上以鼻根为准确定面中线平面为参考平面，在此线上选择1个位于中切牙牙颈部的点，在其矢状位图像上，选取位于口腔内侧骨皮质上距切牙孔后缘6 mm处为标测点，通过此点向硬腭做垂线确定腭骨厚度，测量范围自口腔内腭部骨皮质外侧边缘至鼻腔侧骨皮质外侧边缘。

Upper central incisors moved forward and downward together with maxillary, at the same time they upright in the sagittal plane and tip mesially. 3 The occlusion plane rotated clockwise for about 1.5°. 4 The width increasement effect of RME comes from approximately the equal amounts of skeletal and dental expansion. The mode of dental movement was a combination of body and tipping movements of posterior teeth.
结果：1后牙在宽度方向上为整体移动和倾斜移动相结合的移动方式，但第一磨牙和第一双尖牙稍有差别；牙齿和骨对宽度增加的贡献各占约1/2；2后牙在垂直方向有伸长的趋势；3第一磨牙和第一双尖牙均向前整体移动，轴倾度保持不变；4中切牙整体随上颌骨前部向前向下移动，其牙长轴发生直立，轴倾度增加；5上颌平面发生顺时针旋转。

In pendulum appliance group: the velocity of maxillary first molar distalizing was 0.8mm per month, distal tipping 12.6°,buccal move 0.5mm, horizontal rotation 2.8°; maxillary central incisor move mesially 0.5mm. Conclusion Two methods successfully distalized maxillary molars to appropriate positions.
钟摆矫治器组上颌第一磨牙平均远中移动3.5mm，疗程4.2个月，平均移动速度0.8mm/月；磨牙长轴向远中倾斜角度12.6°；磨牙颊向移位0.5mm；磨牙发生远中舌向水平旋转约2.8°；上颌中切牙切端向远中移动0.5mm。

The clinical characters of oligodontia concluded from this study are following:(1) There is significant difference that more teeth absent and more existent teeth anomalies in patients of oligodontia/S group than in patients of oligodontia/I group, and the peg-shaped upper lateral incisor is the most frequently affected teeth with shape anomaly.(2) Both of the two groups have no significant differences in number of teeth missing between maxilla and mandible as well as that between left and right side.(3) The distribution of teeth missing is bilateral symmetry in both groups, but the frequency of teeth lost are different: excluding the third molar, in oligodontia/I group, the lower second premolar is the most frequently congenitally missing tooth followed by the upper lateral incisor, while in oligodontia/S group, the most frequently missing teeth are mandibular canine and maxillary lateral incisor. Nevertheless, the first molars are the most stable teeth in both groups.(4) In oligodonita/I group, the mean mesiodistal dimensions of all type of existent teeth are significantly smaller than normal value. It is implied that oligodontia is not an isolated phenomenon, but is related to a complex of other dental changes.
对于口腔多个恒牙先天缺失的临床特点有以下初步结论：(1)综合征型先天缺牙患者较单纯型先天缺牙患者恒牙缺失数目更多，平均分别为23.9个和14.9个，且现存牙齿有更多的形态异常，分别为7／10例（70％）和6／22例（27.3％），其中最常见的是上颌侧切牙畸形；(2)两种类型的多个恒牙先天缺失患者的缺牙数目在上下颌及左右侧之间均无差别；(3)两种类型的多个恒牙先天缺失患者在缺失牙位上均呈对称分布，但在具体牙位上有所差异：不计第三磨牙，单纯型先天缺牙最常缺失的牙位是下颌第二双尖牙、其次为上颌侧切牙；而综合征型先天缺牙最常缺失的牙位是下颌尖牙和上颌侧切牙；无论何种情况，第一磨牙均为牙列中最稳定的牙齿；(4)在单纯型先天缺牙患者中，现存恒牙的牙冠宽度较国人正常值偏小，差异显著，提示牙齿形态与多个牙先天缺失有一定相关性。

Thirty-six rats ,weighing(250±10)g, were randomly divided into normal group, experimental group and control group.Orthodontical devices were put between the upper incisor teeth and dens molaris in both experimental group and control group.The corrective force was adjusted to 60g.Salvia miltiorrhiza combination was implanted to each rat in the experimental group every day.The animals of both experimental group and control group were killed at 7,14 and 21 days.The upper dens malarias and periodontal tissue slices were observed under the light microscope and transmission electro microscope,and the X-ray dental films were taken and measured with digitization dental scanning apparatus and its software.
以36只体重(250±10)g的雄性大鼠为样本，随机分为正常组、实验组和对照组，设定不同浓度丹参复合膜，以同体对照方式在正常组进行体内植入实验，在2周内观察不同浓度丹参的牙周组织诱导作用，寻找最佳应用浓度；在实验组和对照组的上切牙与磨牙之间隙安装正畸装置，建立大鼠磨牙移动实验模型，矫治力的大小为60g；实验组每日每只体内植入丹参复合生物膜，两组动物于正畸加力7、14、21d，分三批处死；处死后立即切取双侧上颌磨牙及牙周组织制取标本，制片透射电镜和光镜观察；拍摄X线牙片，用数字化牙科扫描仪及软件对其进行测量分析。
