Abstract:

 Aim: The present study aimed to evaluate the shear bond strength of metal bracket bonded to zirconia and feldspathic porcelain specimens, subjected to different surface treatment, sandblasting (SB) and hydrochloric acid (HF). Materials and Methods: Sixty specimens were constructed for this study. The specimens were divided according to material of construction into two main groups, group (1): Zirconia (Ceramill Amann Girrbach) (30 specimens), group (2): Traditional feldspathic porcelain (Vita VM13)(30 specimens). The two main groups were subdivided according to surface treatment into six subgroup (10 specimens) each treated with (SB) , (HF+silane) or combination of both methods. 60 metal brackets were bonded to the surface treated specimens. Prior to testing for shear bond strength (SBS), all of the bonded specimens underwent thermocycling. Following that, the bond failure mode was noted Results: There was statistically significant difference in SBS values between the two ceramic materials with higher SBS in feldspathic porcelain specimens. The sandblasting treated specimens presented a statistically significant higher SBS values than the HF treated specimens. The adhesive remnant index (ARI) scores were 2 and 5 for most of the groups; There was a statistically significant difference in the proportions of ARI scores between the study groups with higher score 1&2 in feldspathic porcelain sandblasting group Conclusion: Both ceramic material and surface treatment can affect the shear bond strength. sandblasting influences the SBS in both zirconia and feldspathic porcelain specimens.
