Silanization Strengths

Gré et al (74) found that silanization resulted in higher µTBS compared to groups without silane. No significant differences were found between the conventional resin cement and the self-adhesive resin cement with and without silane agent. He concluded that silanization appears to be crucial for resin bonding to LDCs, regardless of the resin cement used. The self-adhesive resin cement acted as well as the conventional resin cement. Higashi et al (75) assessed the effect of sandblasting and silanization on resin cement bond strengths to CAD/CAM resin blocks. Twenty four KATANA AVENCIA blocks were divided into two resin cement groups PANAVIA SA CEMENT HANDMIX [PSA] and PANAVIA V5 [PV5], and then divided into four subgroups according to surface treatment: no treatment (Ctl), sandblasting (Sb), silanization (Si), and Sb+Si. After resin application, μTBSs were measured immediately, 1, 3 and 6 months after water storage. It was found that control treatment yielded significantly lower μTBS values compared to other treatment subgroups. The highest bond strength was achieved with Sb+Si treatment.…show more content…
Twenty four KATANA AVENCIA blocks were divided into two resin cement groups PANAVIA SA CEMENT HANDMIX [PSA] and PANAVIA V5 [PV5]. Each cement group was divided into 4 subgroups: no cleaning (Ctl), ultrasonic cleaning (Uc), acid cleaning (Ac) and Uc+Ac. Then, the μTBSs were measured immediately and after 1, 3, and 6 months of water storage. It was revealed that PV5 group exhibited higher μTBS values than PSA group. Although cleaning after sandblasting was efficient in removing residual alumina particles, it did not have an effect on the long-term bonding durability with non-contaminated CAD/CAM resin
