Bioceramic/bone interface

Sahai, N. and Anseau, M. (2005) Cyclic silicate active site and stereochemical match for apatite nucleation on pseu-dowollastonite bioceramic-bone interfaces. Biomaterials, 26 (29), 5763-5770. 

The presence of pores in materials provides anchor points for the bone and improves the mechanical quahty of the bone/implant interface the increase in the specific surface further encourages cell colonization and the revascularization. While calcium phosphate-based bioceramics are excellent materials for bone reconstruction, they have a low mechanical strength (less than that of the bone), not lending themselves to machining. This resistance diminishes while porosity increases, making the utilization of very porous implants very delicate.
