✦ Synopsis

Self-setting calcium phosphate cement for dental or surgical applications can be prepared by the addition of a liquid to a mixture of acidic and basic calcium phosphate. After hardening, the final compound becomes hydroxyapatite. Using an orthogonal central composite plan, the main factors which control the setting and the final hardness of the cement were defined and models are proposed. The mechanisms of crystallization, the role of free and linked water, and the nature of the final and intermediate compounds are described.

## Abstract Calcium phosphate cement (CPC) that can be injected to form a scaffold in situ has promise for the repair of bone defects. However, its low‐strength limits the CPC to non‐stress‐bearing repairs. Fibrin glue (FG) with good sticking property and biocompatibility is possible used to reinfo
