Replantation of Complete Dislocation of Teeth with Partial Crown Fracture 部分冠折外伤性脱位牙的再植
Most of the teeth harvested from the Shh antibody group were small and abnormal. A single irregularly shaped cusp was visible, and a partial crown formed. The main cusp height in this group was significantly lower than that in the Shh-N group. Shh抗体阻断组形成的牙宽度较小,牙冠形态不规则,只有一个明显的牙尖且牙尖高度较Shh-N体外诱导组和对照组明显变低。
The theory and methods of CAD for three-unit fixed partial dental prosthesis crown bridge are studied, which is based on the design technology of single dental prosthesis crown bridge design. An integrated route of the design of crown bridge is put forward. 本文在基于特征的义齿单冠设计技术基础上,针对三单元固定冠桥的计算机辅助设计理论与方法进行了探索,形成了一套完整的冠桥设计路线。
