Abstract:
OBJECTIVETo observe the influence of three types of dental ceramic alloys on magnetic resonance imaging (MRI).
METHODSNi-Cr alloy, Co-Cr alloy, and Ti alloy were elaborated into three crowns with the same shape and size by computer aided design, computer aided manufacturing device. Afterwards we fixed the crown in the mouth of a volunteer at the same location separately. Then we scanned them with MRI. The extents of artifacts were compared.
RESULTSAll these alloys caused MR artifacts. The extent of the artifact of Co-Cr alloy was larger than those of Ni-Cr alloy and Ti alloy under MRI.
CONCLUSIONTi alloy has the smallest influence on MRI than Ni-Cr alloy and Co-Cr alloy.
