Özet
PurposeTo compare MEP which is originally manufactured for increasing bond strengthbetween organic resins and ceramic with conventional surface treatment methodsin preparation of leucite-reinforced FC surfaces regarding shear bond strength (SBS)of stainless steel brackets and the mode of bond failure.Materials and MethodsForty specimens that were fabricated from FC material and glazed were randomlyassigned to four surface conditioning methods: (1) CoJet Sand; (2) MEP; (3) HF acidetching followed by silane coupling agent; (4) Diamond bur followed by silanecoupling agent. The SBS was determined using universal testing machine. Bondfailure sites were classified according to Adhesive Remnant Index (ARI).ResultsNo statistically significant difference (p>0.05) was found in SBS between the groupswhile significant intergroup differences were detected concerning ARI scores(p<0.001). Group 1 had ARI score 1 and 2 indicating mode of failure at the adhesiveinterface with greater percentage of the adhesive left on bracket base. The othergroups had higher frequency of ARI score 3 and 2. The quantity of the ARI retainedon the ceramic surface was highest in Group 3, followed by Group 4 and Group 2.ConclusionMEP can be a suitable alternative for bonding metal brackets to FC surface.
