Fracture characterization of novel bioceramic microbeads filled polymer composite

The biomaterial poly(l-lactic acid) (PLLA) is commonly used for bone fixation devices and dental surgeries; however its natural osseointegrating ability is generally poor, which can lead to dislocation and partial fractures. Recently, calcium phosphate bioceramics have been incorporated into PLLA in order to redress this issue and improve the osseointegrating ability of the material. This study incorporated calcium phosphate microbeads in PLLA...
