This study compared the firing shrinkages, flexural strengths, and chemical solubilities of two low-fusing porcelains formulated for use with titanium (Procera, Nobel Biocare, Goteborg, Sweden; and Duceratin, Degussa, Plainfield, NJ) to those of a conventional low-fusing feldspathic porcelain (Vita VMK 68, Vident, Baldwin Park, CA). Procera demonstrated the highest mean firing shrinkage and was significantly different from the other two porcelains. There were no significant differences among the porcelains in flexural strength and chemical solubility.
