Impact of Sintering Firing Cycle on Mechanical Properties of Zirconia Dental Restorations

The study investigates the impact of sintering firing cycles on the mechanical properties of zirconia dental restorations, comparing computer-aided design/computer-aided manufacturing (CAD/CAM) milling and fused deposition modelling (FDM) printing methods. CAD/CAM milled zirconia exhibits superior flexural strength and modulus compared to FDM-printed counterparts. Sintering processes do not significantly affect the mechanical properties of either method. Interestingly, the milled speed sintering group demonstrates higher Vickers Microhardness values. These findings suggest that FDM-printed zirconia may not match the mechanical properties of milled counterparts, and speed sintering may enhance certain aspects of milled zirconia restorations.
