铸造支架联合NITI悬臂梁矫正舌倾下颌磨牙的临床效果评价
舌倾 下颌磨牙 NITI悬臂梁 铸造支架
2020/6/4
评价NITI悬臂梁在矫正舌倾下颌磨牙中的临床效果。方法 选择16例单侧下颌第二磨牙舌倾的病例为研究对象,带垫铸造支架连接双侧下颌后牙,提供颌内支抗、解除咬合锁结,0.018英寸×0.025英寸或0.019英寸×0.025英寸NITI悬臂梁提供颊向旋转力矩和压低力。采用Graphpad Prism 6.0 软件对治疗前、后所测数据进行配对 t 检验。

文章摘要：
采用离子束增强沉积法制备TiO2薄膜, 对医用NiTi合金进行表面改性处理.系统研究了薄膜的表面组成、结构、形貌及耐蚀性、亲水性等与血液相容性相关的表面性质. NiTi合金表面沉积TiO2薄膜后,抗模拟体液的腐蚀性提高, 凝血时间延长.为进一步提高TiO2薄膜的抗凝血性,对TiO2薄膜的进一步表面改性—表面结合肝素分子进行了初步尝试,结果表明, ...
文章摘要：
采用溶胶-凝胶法制备TiO2与SiO2-TiO2薄膜，对医用NiTi合金进行表面改性处理。利用X射线衍射(XRD)、原子力显微镜(AFM)、划痕试验和电化学腐蚀试验等手段系统研究了薄膜的结构、形态及性能。通过动态凝血时间和血小板粘附的测量研究和评价了薄膜的体外血液相容性。结果表明，在一定范围内，在较高热处理温度有利于薄膜与基体间的结合强度和耐腐蚀...
