Abstract
Aim: The aim of this study is to evaluate and compare the shear bond strength of ceramic brackets bonded
to porcelain fused metal crowns and metal free ceramic crowns with and without silane coupling agent.
Materials and Methods: 40 metal free zirconia crowns and 40 PFM crowns were fabricated with glazed
surfaces according to the manufacturer’s instructions for the study purpose. The samples were divided in
two groups A and B and each group was subdivided into two subgroups (A1, A2) and (B1, B2)
Sub-Group A1 and A2: Twenty metal free ceramic crowns were etched with 9% buffered HF acid gel for
2 minutes, thoroughly washed and air dried. Relyx ceramic primer (silane coupling agent) was applied to
the treated surface.
Subgroup B1 and B2: 20 porcelain fused metal crowns were etched with 9% buffered HF acid gel for 2
minutes, thoroughly washed and air dried. Relyx ceramic primer (silane coupling agent) was applied to the
treated surface. The shear bond strength of ceramic brackets bonded to porcelain fused metal crowns and
metal free ceramic crowns with and without silane coupling agent.
Statistical Analysis: ANOVA and Post hoc Tukey’s test (HSD) tests were used for statistical analysis.
Result: The result showed that group B1 demonstrate the maximum shear bond strength among all groups
which is 9%HF +Relyx ceramic primer application on porcelain fused metal crowns (10.27+1.31Mpa) and
has highly significant value. Whereas lowest shear bond strength belongs to group B2which is 9%HF and
primer is not applied (5.4+0.73 MPa).
Conclusion: Hence it can be concluded that Relyx ceramic primer is more aooropriate choice for bonding
orthodontic metal brackets on PFM and zirconia surfaces with conventional bonding system.
Keywords: Porcelain fused metal, Shear bond strength, Ceramic brackets, Megapascals.
