Quizplus · Accepted Answer

Nickel has the highest incidence of allergic response.The allergic response is sometimes seen around the free gingival tissues,especially at the margins of base-metal crowns.It is less common for removable partial dentures because the metal often is not in direct contact with the tissues,and they are not worn constantly as with fixed partial dentures or single crowns.Some responses to nickel cause a skin reaction rather than a response in the mouth,even though the oral cavity is the source of the nickel.
