Three different methods for producing porous scaffolds using Ca/P ceramics (Hi-Por method)

A unique foaming technology produces a ceramic foam microstructure comprising of cells, windows and struts. The cells are formed from a series of struts, which are fired to near theoretical density. By varying the processing parameters, the material can be produced with porosities between 50 and 90%. The size of the macropores and the interconnections between can be readily adjusted. The gel casting method employed allows the production of near net shape forms with either simple or complex geometry. The product can also be easily machined using conventional equipment.

This technique has now been developed and optimised for use with biocompatible materials (calcium phosphates) such as hydroxyapatite (HA), tri-calcium phosphate (TCP) and biphasic HA/TCP. From the batches produced, discs for in vitro studies and blocks and granules for in vivo studies and physical and mechanical characterisation have been inputted into the PORELEASE project. Produced under controlled conditions and specifications using the ISO EN 13485 standard, HI-POR's scaffolds are approved for CE marking as Class III medical devices.
