Objective: To evaluate the influence of the barium glass (BG) filler in 3D printing resin-based composites for restorative structures.
Methods: Experimental 3D printing resin-based composites were formulated with UDMA 70%wt, Bis-EMA 20%wt, and TEGDMA 10%wt. Photoinitiators TPO and DFI (2%wt) were used.
