The lifespan of zirconia-based ceramic implants depends on material as well as surface and subsurface properties. Latter are determined by thermo-mechanical loads due to the manufacturing process. Common methods characterize the residual strength behavior by mechanically damaging the surface by indenter impressions, which exclude the thermal influence of the production process. Furthermore, the mechanical load is so far not correlated with the loads while grinding. Hence, a novel approach is presented characterizing the residual strength behavior after grinding by correlation of manufacturing technological parameters with the measured bending strength. The novel correlations are used to identify the most efficient grinding parameters assuring highest functional reliability. The approach is demonstrated by comparing conventional 3Y-TZP ceramics and a newly developed damage-tolerant zirconia-based material, which combines increased bending strength and higher toughness. Thus, the functional performance of future dental implants can be increased as well as the productivity of the machining processes.
