Evaluation of mechanical properties and color stability of 3D-printed denture base materials following two surface treatments

Glaze application resulted in improved mechanical strength and hardness for the majority of 3D-printed groups; however, its capacity to effectively reduce surface roughness and discoloration was consistently limited. Conversely, mechanical polishing maintained its beneficial effects, demonstrating clinically acceptable values across all assessed parameters. Therefore, comprehensive additional investigations are necessitated to fully elucidate the performance characteristics of glaze materials and their interactions with 3D-printed denture base materials.
