Preparation and Studies on Preshaped Porous Scaffolds for Tissue Engineering 组织工程预塑形多孔支架的制备和研究
Objective The purpose of this study was to qualitative and quantitative analyze the initial force system of preshaped rocking-chair archwire on every tooth. 目的通过建立有限元模型对预成摇椅弓施予牙弓中各个牙的初始力系统进行定性定量研究。
The most key technological step is a two-step anisotropic etching of KOH ∶ H2O to ( 100) silicon substrate with resistant mask in which many circular openings are preshaped. 此方法的关键步骤是(100)硅在KOH∶H2O中的两步各向异性腐蚀。
In 108 cases using the special preshaped guide wire, the success rate of catheterization was 100%. 对108例患者利用特制钩形角部定位导丝行介入再通,插管成功率为100%。
