Abstract
This paper presents the mechanical properties and SEM studies of bone cements reinforced by bovine hydroxyapatite (BHA), synthetic hydroxyapatite (HA), and β-tricalcium phosphate (β-TCP). All ceramic fillers were silane treated with γ-methacryloxy-propyl-trimethoxy silane (A-174, 0.2%). The quantities of silane treated ceramic fillers in cement were 1.5 wt.%, 2.5 wt.% and 3.5 wt.%. Commercial CMW™3 bone cement was used as control group. The results showed that there is no decay of mechanical properties if the amount of bioceramic additives does not exceed 2.5 wt.%. Similar microstructures were observed by SEM at the fracture surfaces of the bioceramic reinforced bone cements and the control group.
