Abstract
Introduction
Adhesive cementation, with pure ceramics, is a relevant step in establishing the longevity of prosthetic works. Being these, the best materials used for the replacement of lost teeth, in order to rehabilitate the smile. The ceramic zirconia system does not benefit from the treatment and planning needs for its surface, effectively in adhesive therapy.
Objective
Evaluate the results of different blasting techniques and application of bonding agent for metals and ceramics (Ceramill ZI®) by means of a tensile test in two different surface treatments.
Material and method
Twenty samples of Ceramill Zi® (n = 20), cylindrical and joined with resin cooling (Multilink®), were prepared, forming 10 specimens (n = 10). The first 10 ingredients were formed by 7 experimental groups and they received 2 surface problems: abrasion and application of silane bonding agents.
Result
The research resulted in fracture resistance of Rocatec® silica specimens. The values of tensile strength, measured in MPa, of groups 1 to 7, were: 2.27; 4.48; 8.06; 8.32; 9.15; 10.56 and 10.70. We observe how to enter the groups are statistically significant, except between groups 3 and 4 and between 6 and 7.
Conclusion
The results of the ceramic surface treatment were based on no silicate method, promoting the union of results with Ceramill ZI® and cemented with Multilink®.
