The aim of this study is to assess the bond strength of three resinous cements to Zirconia Katana™ UTML (Kuraray Noritake Dental Inc, Miyoshi, Aichi, Japan). Thirty-six blocks of Zirconia were milled and included in polyvynil chloride (PVC) pipes with self-polymerizable acrylic resin. Each sample was polished in a polishing machine, blasted with aluminum particles, cleaned with ultrasound, and dried with compressed air. The cementation was done according to the protocol recommended by the manufacturer. The samples were divided in 3 groups (n=12) according to the resinous cement used: Group R - RelyX™ U200 Automix (3M ESPE, Sumaré, São Paulo, Brazil); Group M - Multilink® N (Ivoclar Vivadent, Schaan, Liechtenstein); and Group P - Panavia™ V5 Paste (Kuraray Noritake Dental Inc, Cotia, São Paulo, Brazil). The shear stress test was performed in EMIC DL2000 (EMIC, São Paulo, SP, Brazil), and failure type was analyzed. Average bond strengths were 5.4 kgf, 5.8 kgf, and 6.68 kgf for groups R1, M1 and P1, respectively. Variance analysis showed no significant difference between groups. None of the groups showed cohesive failure; there was no significant difference in the frequency of mixed and adhesive failure between groups. All three cements showed similar performance in the tests.
