Summary
Fixed partial dentures (FPDs) can cause artifacts in magnetic resonance imaging (MRI) scans, reducing image quality for head and neck diagnostics. This review examines methods and findings related to FPD artifacts in MRI.
Area of Science:
- Radiology and Diagnostic Sciences
- Biomaterials and Medical Devices
Background:
- Fixed partial dentures (FPDs) are common dental restorations.
- Magnetic resonance imaging (MRI) is a crucial diagnostic tool.
- Metallic FPDs can cause significant artifacts in MRI, particularly in head and neck imaging.
Purpose of the Study:
- To review research on artifacts produced by fixed partial dentures in MRI.
- To analyze the methods, characteristics, and results of studies investigating FPD artifacts.
Main Methods:
- Literature review of studies on FPD artifacts in MRI.
- Analysis of artifact characteristics and influencing factors.
- Categorization of research methodologies used in the field.
Main Results:
- FPDs generate artifacts that degrade MRI image quality.
- Artifacts can obscure anatomical details in head and neck regions.
- Various factors influence the type and severity of MRI artifacts.
Conclusions:
- Understanding FPD artifacts is crucial for accurate MRI interpretation.
- Further research is needed to mitigate artifact impact.
- Improved imaging protocols may reduce diagnostic challenges posed by FPDs.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
