The MR-visualization of the very rigid composite
materials for dental care appears to be impossible by MR
methodology based on spin echo detection due to the very
short T2* of the polymer and ceramic compounds. However
we demonstrate here the possibility to visualize the
solidifying process during illumination at high spatial
resolution in these very rigid Biocompatible
polymer-ceramic composites using UTE T2* micro-mapping
on a 7T Ultra-High-Field human scanner. Quality control
analysis allows for the detection of possible sources of
artifacts in UTE-imaging. Inhomogeneities in the
composite as possible source for mechanical failure are
detected.
