Surface morphology is an essential factor
for biocompatible materials and strongly influences the interaction within
organic materials.
Surface
Parameters
Surface parameters as roughness and shape of
the structures will determine ability and rate of bone healing against the
implant surface as well as the final strength of the bone to implant contact and
even the degree of bacterial contamination.

AFM
Investigation
Investigation of surfaces of such materials
with an AFM can contribute to the understanding of the biocompatibility of new
materials by determining crucial surface information without modifying the
materials and surfaces. The figure shows a AFM image of the tooth enamel surface
structure.
The image was recorded with an easyScan2 AFM operated in dynamic
mode. |
