THE PHYSICAL-PROPERTIES OF LOW-FUSING PORCELAINS FOR TITANIUM

This study compared the firing shrinkages, flexural strengths, and che mical solubilities of two low-fusing porcelains formulated for use wit h titanium (Procera, Nobel Biocare, Goteborg, Sweden; and Duceratin, D egussa, Plainfield, NJ) to those of a conventional low-fusing feldspat hic porcelain (Vita VMK 68, Vident, Baldwin Park, CA). Procera demonst rated the highest mean firing shrinkage and was significantly differen t from the other two porcelains. There were no significant differences among the porcelains in flexural strength and chemical solubility.
