Development of Load Bearing Capacity Resorbable Calcium Phosphate Cement

Abstract

Jacob Luke

The study of the microstructure reveals that several small pores (approximately 25-50 μm in diameter) were uniformly dispersed around the surface of the sample. The grains were flake-like, ranging from a diameter of 100 nm to 1 μm and a thickness of around 40 nm. The cement displayed a high injectability of > 90 percent by weight, and no apparent filter pressing was noted during ejection. The XRD study of dried samples found that a total of approximately 17 percent of unreacted β-TCP and β-CPP were still present in the cement, while all MCPM had reacted. Brushite was the predominant precipitated element, with approximately 5% wt of current monetite.
