Effect of Polymer Solution Viscosity on Injectability of Calcium Phosphate Cements

摘要

Increased solution viscosity leads to reduced injection force and increased injection volume for the model CPC tested. Solution viscosities of above 90 cP led to smooth reproducible injection for all polymers tested. Except for HPMC, the polymers had little effect on cement compressive strength or setting kinetics as measured by the setting force test.
