Abstract | Hydroxyapatite (HA) is the calcium-phosphate material with composition closest to that of bone, what makes it suitable for osseous implant purposes. This material was used to produce macroporous structures with pores larger than 100 μm, which are believed to be suitable for allowing bone ingrowth. The macroporous structures were generated and consolidated by combining foaming and starch consolidation methods. The porous structures could be tailored according to the final application by varying the proportion of different foaming agents, foam-bath concentrate (FBC) and sodium lauril sulphate (SLS). Playing with these proportions it was also possible to improve foam stability and model the size of pores and pore interconnections in order to reproduce the pore structure of natural bone. |
