ProsthodonticsPacking acrylic resin in the sandy stage, which refers to a stage where the material is not fully polymerized and has a grainy texture, can lead to porosity in the final product. This occurs because the incomplete packing can trap air bubbles, resulting in a porous structure that compromises the strength and integrity of the restoration.
