The cellular response to and a trace element released from implant materials is conditioned by their surface characteristics. The effects of commonly used preparative procedures on porous and solid samples of Ti6A14V, Co-Cr-Mo, single crystal A12O3 and synthetic hydroxyapatite (HA) have been studied by SEM, EDX, ISS, SIMS and ESCA. Some of the results for Ti6A14V and HA discussed here show that the surface of implant materials may be highly variable as a result of uncontrolled preparative procedures. Standardized preparative procedures and adequate characterization are needed to understand the interaction between tissues and implant materials.
