TI  - Effect of fiber patterns on the fracture of implant/cement interfaces.
PG  - 32-38
AB  - Electrospinning is a process by which fibers with micron to nanometer diameters 
      can be obtained from an electrostatically driven jet of polymer solution. These 
      fibers have a high surface area to volume ratio, which have numerous applications 
      in biomedical implants such as total hip implant, dental implant. The present 
      study is based on the hypothesis that the differences of the surface properties 
      at titanium/cement interface due to incorporation of micro and sub-micron 
      diameters fiber directions may have influence on the quality of titanium/cement 
      union. The objectives of this research were to design and construct 
      electrospinning unit for the fabrication uni-and bi-directions polycaprolactone 
      (PCL) fiber on titanium and to measure the effect of fiber directions on the 
      interface fracture strengths of sandwiched titanium (Ti) and poly methyl 
      methacrylate (PMMA) cement samples with (uni-and bi-directions) and without 
      fibers. Two groups of single edge sandwiched Ti/PMMA specimens were prepared. 
      First group of specimen consists of Ti/PMMA sandwiched specimen without PCL 
      fiber. Second group of specimen consists of Ti/PMMA sandwiched specimen with 
      uni-and bi-direction PCL fibers. PCL fibers were ejected from the syringe via 
      charged needle and deposited on two different grounded collectors to coat uni-and 
      bi-directions PCL fibers on Ti plates. PMMA cement was poured and cured on the Ti 
      plates with and without PCL fibers in a custom made mold to prepare Ti/PMMA 
      samples with uni-and bi-directions fibers. Shear tests were conducted on each 
      group of Ti/PMMA samples using Evex tensile test stage. Interface fracture 
      toughness was calculated to determine the effect of fiber patterns on Ti/PMMA 
      samples. This study successfully produced an electrospun unit that can produce 
      uni-and bi-direction PCL fibers. Diameters of produced fibers were found to be in 
      the range of 919 nm ~1.25 mum. This study found that the values of K(IC) of 
      Ti/PMMA with uni-direction fiber were significantly higher when compared to the 
      values of K(IC) of the Ti/PMMA without fiber (p<0.05), although the values of 
      K(IC) of Ti/PMMA with bi-direction fiber were significantly lower when compared 
      to the values of K(IC) of the Ti/PMMA without fiber. Results indicated that the 
      addition of the fiber to Ti improved the quality of Ti/PMMA union and fiber 
      directions have significant effect on the strength of the Ti-PMMA union.
