Metal-supported ceramic restorations have been utilized effectively in fixed prosthetic restorations for many years. However, difficulties like as fractures in the infrastructure and/or superstructure, cracks or ruptures in the superstructure, and failure to completely satisfy the aesthetic expectations are experienced over time in these prostheses, which are commonly made by the casting process. As a result of this, intensive research is being conducted on both the development of infrastructure materials and the development of manufacturing techniques. The effect of the macro/micro bond strength between metal and ceramic was investigated in this research if the metal substructure of the fixed prosthesis is manufactured as a lattice structure rather than a solid using additive manufacturing. The infrastructure was produced in the study as a full-mass and lattice cylindrical structure with a diameter of 1 mm and a length of 1 mm. Following the formation of the lattice structure as diamond and octet-truss structures, ceramic coatings were applied in compliance with clinical application requirements. The samples were compressed to analyze their mechanical characteristics. After the test, the diamond lattice structure, full-mass, and octet-truss lattice structures showing progressively lower toughness. The results were statistically evaluated, with averages of 243.4775, 225.655, and 192.74 for diamond, solid, and octet-truss structures, respectively. The Shapiro–Wilk normality test was performed on each structure, and all structures are appropriate for normal distribution because they had Sig > 0.05 values. Finite element analysis was used to validate the obtained results. The experiment found that the lattice structure is more advantageous in the direction of ceramic coating because it enhances impact absorption energy and the resistance of the ceramic layer to cracking.
