Abstract
Purpose
The objective of this study is to investigate the influence of cement space, surface treatment and resin cement type on the bond strength between monolithic zirconia copings and Ti-base abutments.Materials and methods
Eighty Ti-base abutments were connected to analogs, embedded in acrylic resin and specimens were prepared. Monolithic zirconia copings with cement spaces of 50 µm and 110 µm were fabricated using CAD-CAM. All zirconia bonding surfaces were sandblasted with 50 µm Al₂O₃. The specimens were allocated to 8 groups (n = 10) according to Ti-base abutments surface treatment (primer only/airborne-particle abrasion+primer) and resin cement type (Multilink Hybrid Abutment/G-CEM LinkForce). Following cementation, specimens were subjected to 10,000 thermocycles and tensile testing. The resulting data were analyzed using one-way ANOVA and post-hoc tests (P < .05).Results
Mean tensile force values differed significantly among groups (P < .05). The highest mean bond strength was observed in Group 5 (535.93 ± 71.42 N), and the lowest in Group 4 (207.31 ± 40.57 N). Airborne-particle abrasion groups (Groups 5 - 8) showed significantly higher tensile force values than the other groups (P < .05).Conclusion
The bond between Ti-base abutment and monolithic zirconia depends on multiple factors. In the current study, the higher bond strength obtained in the groups containing Ti-base abutments sandblasted with 50 µm Al₂O₃ indicates that surface roughening may play an effective role in improving bonding performance. However, the lack of significant differences in cement space and resin cement composition among the sandblasted specimens suggests that the effects of these parameters may be more limited than that of surface treatment.
