Evaluation of the state of the marginal gum in the vicinity of the abutment teeth of the patients using for a long time unremovable metalloceramic constructions based on the alloys of noble and base metals

A total of 44 patients were enrolled for the examination. All of them during a long time used unremovable metallic ceramic prostheses with the framework manufactured from the gold-containing "Super KM" alloy or the "KXC" cobalt-chromium alloy. The results of the study indicate that 34% of the patients presented with the clinical manifestations of gingivitis differing in the degree of severity. These symptoms were unrelated to the possible negative effects of the metal ions contained in the alloys.
