Objective: The shear bond strength of four adhesive resins bonded to GI II glass infiltrated alumina ceramic was investigated in this experiment.
Methods: A total of 40 ceramic blocks and 40 tooth blocks were prepared and divided into 4 experimental groups, including group A (CereDual and silicoating), group B (Calibra and silicoating), group C (Panavia) and group D (Super C&B and silicoating). The shear strength of four different bonding systems to dentin was tested respectively. The data were statistically analyzed.
Results: More than 13 MPa of bonding strength was achieved using the traditional Bis GMA bonding resin (groups A and B), and more than 16 MPa was obtained using the improved Bis GMA bonding resin (group C and D). There was statistical difference between groups A, B and group C, D.
Conclusion: It can be implied that an ideal bonding can be obtained by using different bonding materials and processing the dentin surface with the suitable conditioner.
