title: Allergic contact stomatitis caused by a titanium nitride-coated implant abutment: a clinical report.
abstract: A patient developed contact mucositis after being treated with a titanium nitride implant abutment. Patch testing disclosed a positive reaction to titanium nitride. After removal of the titanium nitride-coated abutment and placement of an uncoated abutment, all signs and symptoms disappeared. This clinical report suggests that titanium nitride-coated abutments may be a potential allergen in some patients.
