Notes:
Porous calcium phosphate ceramics have been widely investigated in orthopaedicsurgery as bone extensor. Attention has been given to manufacturing of a porous bioceramic thatmimics the trabecular bone structure for proper bone regeneration and integration. Althoughdifferent methods have been applied to manufacture the porous structure, it was unable to visualizethe pores and their interconnections within the ceramic and had objective measurement of thecalcium phosphate ceramics. With the advance of biomedical imaging through micro-computedtomography (microCT), the study attempted to quantify the pore structure of different calciumphosphate ceramics. Three kinds of bioceramic blocks, namely BSC, ChronOS, and THA, weresynthesized by three methods and tested in the study. Six blocks of each bioceramic were evaluatedby conventional water immersion method and microCT. The pore size and connectivity of the poreswere evaluated with standardized protocols. The three-dimensional analysis of the pores and theirdistribution by microCT was presented. The ChronOS had more functional pores (200-400μm indiameter) than the BSC and THA did (p〈0.05). Providing objective information on the functionalpores, the microCT evaluation serves as a good standard for specification of the bioceramic-relatedimplants
