Abstract:

The objective of this study is to prepare 3D printed cytocompatible bioglass-TCP scaffolds with an optimum combination of porosity gradient and mechanical properties. Bioactive glasses (bioglass) are an excellent candidate for bone tissue engineering applications because of their excellent biological response and high dissolution rate. Tricalcium phosphate (TCP) are used for craniomaxillofacial applications owing to their chemical similarities with natural bone. Our results indicate that upto 5 wt.% bioglass addition in TCP enhances the compressive strength of the prepared scaffolds ~ 26.675 ± 5.45 MPa as compared to ~ 8.50 ± 0.830 MPa of control TCP. Simulated body fluid (SBF) dissolution study reveals that bioglass addition in TCP significantly improves the dissolution precipitation. Thus, this work affirms that 3D printed bioglass-tcp scaffolds can be a promising material for various biomedical applications. This poster will discuss fabrication of 3D printed bioglass-tcp scaffolds with optimum mechanical properties and controlled dissolution rate.
