| Abstract: | Precious dental alloys based on gold, platinum, palladium or silver exhibit excellent corrosion resistance, high biocompatibility and optimal mechanical properties for use in prosthetic dentistry. In comparison, base dental alloys based on chromium, cobaltor nickel are cheaper, have excellent mechanical properties but poorer corrosion resistance and biocompatibility. This research examined the magnetic properties of dental alloys in a magnetic field, which vary with composition and electronic structure. Materials can be classified as diamagnetic, paramagnetic or ferromagnetic, depending on how they respond to an external magnetic field, with noble metals usually showing weak or negligible magnetic behaviour. Experimental results of magnetic force measurements in precious dental alloys have shown that most exhibit diamagnetic properties, being weakly repelled by a magnetic field, and do not retain any magnetization when the magnetic field is removed. One of the tested precious-metal alloys ex-hibited paramagnetic behaviour, indicating a weak attraction in a magnetic field. In contrast, all studied dental base-metal alloys exhibited stronger paramagnetic interactions with magnetic fields. Diamagnetic properties of precious-metal dental alloys present a significant advantage in the medical environment, especially in magnetic resonance imaging (MRI) as diamagnetic materials do not interfere with magnetic fields and thus reduce image distortion and patient risk during MRI. However, paramagnetic base-metal dental alloys can cause local heating or imaging artefacts under MRI conditions. Therefore, precious-metal dental alloys are more suitable for patients who may require MRI, as they combine functional durability with greater safety in medical diagnostics. |
