Abstract

A wide variety of bioactive composites for bone regeneration have been developed and investigated over the last decades. In order to promote bioactivity, certain types of glasses, ceramics and minerals are incorporated into biodegradable or biostable polymers. In this study, several established and novel fillers such as calcium phosphates, silicates and glasses were screened for bioactivity. Promising candidates were then incorporated into two different grades of poly-ε-caprolactone by solution mixing, and testing was conducted in a simulated body fluid to determine in vitro bioactivity. At different time periods the exposed samples were characterized by SEM, EDX and FTIR microscopy in order to investigate the formation of the apatite layer needed for bone ingrowth. The screening results of this work produced suitable polymer/filler combinations for further in vitro and in vivo testing in different types of tissue engineering applications.
