Preparation of calcium phosphate cement with an improved setting behavior

Abstract

In the aim of the development of a calcium phosphate cement (CPC) that allows a sufficiently long kneading time at room temperature while sets promptly at a physiological temperature, the powder components of a CPC of a TeTCP-α-TCP-DCPD system were coated with gelatin. The gelatin coating on TeTCP or DCPDcontaining portion effectively retarded the setting reaction at 293 K while it did not hinder at 310 K, implying the possibility of CPC with an improved setting behavior. Compressive strength of 41 MPa was attained for a gelatin-coated CPC. © 2013 The Ceramic Society of Japan and the Korean Ceramic Society.
