摘要: Aim: The purpose of this study was to evaluate the bond strength metallic crowns cemented straight and angled customizable abutments with zinc phosphate. Material Method: Thirty-nine external hex analogs were divided in group S: abutment (n = 10), A17 17° 10) A30 30° all metal copings onto their corresponding dies according manufacture guidelines. Data from groups compared a 1-way ANOVA (α=.05) Tukey’s test. SEM evaluation performed 3) aiming investigate microscopic features abutment-cement-crown interfaces. Results: mean force (SD) required dislodge S, 357.26 (62.21) N; 251.50 (20.13) N 276.70 (17.96) respectively. Tukey test (p <0.05) revealed significant statistically differences between =.002) similar each other different abutments. Zinc phosphate showed an inhomogeneous cement line analysis. Conclusions: Within limitations study, it can be conclude that available surface area convergence axial walls positively influenced
