1. Different stress distributions of lower cuspid were presented when different forces were applied. Conclusion:The 3-D FEM model established through DICOM data showed ex...

2. Conclusion: Predicting the tooth size of cuspid and bicuspid group in malocclusion can't simply follow the law of normal occlusion.

3. Methods: A 3-D FEM model of lower cuspid was established by using DICOMdata and stimulant mechanical experiment was carried out on the model.

4. Impacted tooth frequently appears in upper cuspid and upper central incisors(except of the third molar) .

5. Serious tooth defect which involved cuspid, incisal angle, marginal ridge and occlusal surface can't be filled and need occlusal reconstruction.

6. Taxol content in needle and swig of Taxus yunnanensis was the highest within four species from East Asia area, Taxus cuspid...

7. The vertical shifts of brackets could change the preadjusted torque value and the design of cuspid bracket should have the distinction between mesial and distal shape.

8. Objective: To study the tooth size correlation between permanent cuspid and bicuspid group and other teeth groups in malocclusion.

9. After treatment the changes of dental arch width in first and second premolar region were larger than that of cuspid and first molar regions.
