The past few years have seen great efforts in prosthodontics to find a way of replacing the metal portion necessary in the construction of ceramic veneer crowns by nonmetallic anorganic materials. As a result, various novel procedures for the production of fully mineral crowns have been developed. Among these, the Hi-Ceram system has attained particular attention. In a clinical study the reactions of the marginal gingiva to Hi-Ceram have been compared to those to ceramometallic crowns.
