Biodegradable polymer has been widely used in surgical suture, dressing, artificial bone and other bone-related applications. Studies have demonstrated that metals, such as titanium, titanium alloys or 316L stainless steel, can be widely used in dental and maxillofacial surgeries. The present study aimed to fabricate a scaffold with a blend of multilayer polylactic acid (PLA) ply yarns with 316L stainless steel (SS) braids, which was then immersed in simulated body fluid (SBF), forming the PLA/SS composite braid with hydroxylapatite deposition. After being immersed in SBF for 14 days, the PLA/SS composite braid was covered with precipitate which was confirmed to be apatite deposition according to surface observation and EDS evaluation.

The Individual

Biodegradable polymer has been widely used in surgical suture, dressing, artificial bone and other bone-related applications. However, when compared with the human cortical bone, the pure polymer obviously did not have enough strength. The present study aimed to give preliminary insights from a pilot study of designing a scaffold of polylactic acid ply yarns composited with stainless steel (SS) braids. To evaluate the fabrication processes and alkali effects on the individual materials, the different heating temperature and alkali treating time and alkali concentration were applied to clarify the changes in mechanical strength. The experimental results showed that the strength was not significant declined with alkali and heating treatments. The retained mechanical strength was kept at 100-120 MPa and ultimately led to bone-like mechanical properties.
