The need for suitable bone grafts is high; however, there are limitations to all current graft sources, such as limited availability, the invasive harvest procedure, insufficient osteoinductive properties, poor biocompatibility, ethical problems, and degradation properties.
This material shows insufficient tribological properties.
Abundant amount of these defects may result in insufficient switching properties.
However, insufficient mechanical properties, labour intensive preparation process, long client's visiting times urge us to seek an alternative.
However, there are still some drawbacks to be overcome such as insufficient mechanical properties and long degradation period.
Despite the promising characteristics of nanofibers, insufficient mechanical properties, hydrophobic nature, ineffective pore-structure controllability, shrinkage, and distortion are identified as some limitations.
However, current bioinks for skin printing rely on homogeneous biomaterials, which has several shortcomings such as insufficient mechanical properties and recapitulation of microenvironment.
However, recent aerospace materials still face some major challenges, such as insufficient mechanical properties, fretting wear, stress corrosion cracking, and corrosion.
In animal studies so far, the implanted TEHVs have failed to survive more than a few months after transplantation due to insufficient mechanical properties.
However, the use of polyolefins in some demanding areas, such as high-temperature engineering applications, is limited due to their low melting temperature and insufficient mechanical properties.
