Abstract: 

Purpose: The aim of the study was to investigate the influence of various depths of reduction of the abutment tooth on the fracture resistance of monolithic zirconia bridge in vitro, with the null hypothesis that the depth of tooth preparation of the abutment has no statistical influence on the fracture resistance of the monolithic zirconia bridge Materials and Methods: Abutment Tooth preparation is done on phantom teeth no 45 and 47 with the below mentioned depths. Casts are made from the impressions and 5 bridges for each group are manufactured using CAD/CAM. All the 15 bridges are cemented on respective metal dies using glass inomer cement and tested on an Instron testing machine for fracture resistance. The results are tabulated and statistically analyzed. Results: The statistical analysis (ANOVA) of this research showed that there is significant difference between mean resistance scores among the three groups. Furthermore, LSD post hoc test revealed that the mean resistance score for group 3 is significantly higher than both group 1 and 2. There was no statistically significant difference in resistance scores between group 1 and group 2. Conclusion: Within the limitations of this study, the following conclusions can be drawn: 1. The depth of tooth preparation of the abutment has significant influence on the fracture resistance of monolithic zirconia crowns and bridges, with 2mm occlusal reduction displaying the best possible fracture resistance strengths. 2. The monolithic zirconia bridge made over the tooth preparation of the abutment with 0.5mm of reduction circumferentially, showed a significantly lower fracture resistance and might exhibit fractures during mastication. 3. The monolithic zirconia bridge made over the tooth preparation with 1mm of occlusal reduction of the abutment performed slightly better than that of 0.5mm reduction but is still significantly weaker than that of 2mm occlusal reduction.
