Bonding strengths overwiev. Average adhesive bonding strengths and standard deviations detected in a study of Maurer et al. using different kinds of bonding agents like dentin bonding agents (Excite, Clearfil New Bond, Etch & Prime®3.0) and tissue adhesives (Cyano Veneer®, Histoacryl®) [3, 29, 31], compared with the average bonding strength reached with the self-made amphiphilic bone bonding agent. The bonding partners variations: porcine bone/Tetric® colour A2, porcine bone/porcine bone and bovine bone/PMMA cement. Tensile strength tests were done at day 0 (day of preparing the samples, without storing the samples).
