EXT STUDY RESTORATION Bond Strength of the self adhesive cement SoloCem® to indirect restorative ceramic Priv. Doz. Prof. Dr. U. Lohbauer Universitätsklinikum Erlangen Report to Coltène, 09/2013 The objective of this study was to assess the bond strength (tensile bond strength, TBS) of a self-adhesive resin cement SoloCem compared to a conventional resin cement Multilink® Automix which is used with MonoBond® Plus on zirconia and on lithiumdisilicate ceramic before and after thermocyclic loading. EXPERIMENTAL SETUP The pretreatment of the lithiumdisilicate (IPS e.max Press®) was HF etching and the pretreatment of the zirconia (IPS e.max Press®) was sandblasting (aluminum oxide 35 µm). SoloCem was used without additional Primer. Multilink® Automix was used with the Primer MonoBond® Plus. The resulting tensile bond strength was measured after 24 hours water storage at 37°C and after thermocycling with 5000 cycles between 5 and 55°C. Number of specimens for each group was 15. Tensile bond strength on zirconia before (24h) and after thermocycling (TC) RESULT On Zirconia SoloCem showed better tensile bond strength before and after thermocyling compared to Multilink® Automix with Primer. On lithiumdisilicate SoloCem produced significant higher bond strength before thermocycling compared to Multilink® Automix with Primer. Tensile bond strength on lithiumdisilicate before (24h) and after thermocycling (TC) IPS e.max Press®, Multilink® Automix and Monobond® Plus are not Trademarks of COLTENE
