title: Nickel sensitivity: a case report.
abstract: In dentistry, three "non-precious" alloy groups predominate: chromium-cobalt, nickel-chromium, and nickel-chromiumberyllium. These alloys have little or no precious metals, but exhibit low flexibility and achieve high porcelain-to-metal bond strengths when handled properly. The most common of the "non-precious" metal alloys utilize nickel; unfortunately, nickel is the most common of all potential metal contact allergens. This article describes a case involving a patient with a sensitivity reaction to the metal component of a ceramo-metal crown and the procedure that was used to rectify the problem.
