Calcium phosphate cements (CPCs) are frequently used to repair bone defects. Since their discovery in the 1980s, extensive research has been conducted to improve their properties, and emerging evidence supports their increased application in bone tissue engineering. Much effort has been made to enhanc...
Calcium phosphate cements are used as synthetic bone grafts, with several advantages, such as their osteoconductivity and injectability. Moreover, their low-temperature setting reaction and intrinsic porosity allow for the incorporation of drugs and active principles in the material. It is the aim of...
Calcium phosphate cements (CPC) consist of one or more calcium orthophosphate powders, which upon mixing with water or an aqueous solution, form a paste that is able to set and harden after being implanted within the body. Different issues remain still to be improved in CPC, such as their ...
The ratio between the concentration of silica in the cement powder and the phosphate concentration in the cement liquid was crucial for tailoring the properties of the CPC. Cements with 5 wt% ULP SBA-15 as seed material could be used in a clinical setting for load-bearing applications. 展开 ...

Calcium phosphate cements are blends of calcium phosphate compounds and set to produce HA. The final products have excellent biocompatibility, osteoconductive properties and a high compressive strength, and it is slowly resorbed. Calcium phosphate cements represent an intriguing group of new materials for...

Macroporous calcium phosphate cements (CPCs) were developed using genipin-crosslinked gelatin microspheres (GMs) with two weight ratios (2.5wt% and 5wt%). The initial setting time of the composite was prolonged by GMs. After GMs/CPCs were soaked in phosphate-buffered saline (PBS) for several we...
The porosity of calcium phosphate cements has an impact on several important parameters, such as strength, resorbability and bioactivity. A model to predict the porosity for biomedical cements would hence be a useful tool. At the moment such a model only exists for Portland cements. The aim of...
