Artifacts induced from dental alloys are potential pitfall in dental MRT. Depending on the imaging sequence and the material used, susceptibility as well as eddy current artifacts are more or less distinct. In dental implantology, a titanium implant is inserted into the jaw bone. For virtual modeling of a fixed partial denture, the orientation of the in situ implant must be recorded along with the neighboring teeth, enabling the dental technician to model a well-fitting restoration. This is achieved by affixing a scan abutment with a defined shape that can be detected by pattern-recognition in the scan results.
