Bone Cement 骨水泥

Biphasic Calcium Sulphate 硫酸钙（石膏 ）

Although Orsini and co-workers have shown that there is no difference in the bone healing pattern between preset （已凝固）CS dihydrate granules and moldable （可塑性）CS-hemihydrate cement. (Orsini 2004), by using preset CS dihydrate the surgeon loses advantageous handling properties of the moldable cement derivative.

By making use of the biphasic calcium sulfate concept in 3D Bond™ the previous setting issues can be solved: The CS hemihydrate component is controlling the cement consistency and moldability characteristics. The dihydrate component is regulating the setting properties. Using this formulation, the setting process can be reduced from about 20 minutes to 3 minutes, also under in vivo conditions in presence of blood and saliva.

The key performance criteria of CS-derived graft materials that were shown in numerous studies is the fast and effective vital bone formation as a result of the rapid dissolution in vivo. (Thomas and Puleo 2008, Toloue, Dahlin) These characteristics provoke advantageous clinical results in small and well-contained bony defects like extraction socket filling. (Toloue, Guarnieri) .
