>25% noble is classified as?

high noble
noble
base metal
non-noble

The correct answer is: noble

A dental alloy containing over 25% noble metals, such as gold, platinum, and palladium, is classified as a "noble" alloy. Noble alloys have excellent biocompatibility and corrosion resistance, making them suitable for use in dental restorations. In contrast, high noble alloys contain even higher percentages of noble metals, making them particularly valuable for their biocompatibility and esthetic qualities. Base metal alloys, on the other hand, contain little to no noble metals and are more susceptible to corrosion and biocompatibility issues. Non-noble alloys fall within this category, making them less ideal for certain dental applications compared to noble or high noble alloys.
