Hello Members,

Cold-pour acrylic, also called cold-cure acrylic, is used to make temporary dentures, duplicate dentures, inexpensive, basic or affordable dentures, and for denture repairs. During their creation, dentures go through a process of polymerization, which hardens the acrylic. The degree of hardness depends upon the process used. Cold curing does not adequately harden the acrylic. The researchers participating in this study determined heat-cured acrylics to be the hardest and most durable denture material. The teeth used to process a permanent, heat-cured dentures are separately manufactured from a stain and odor-resistant acrylic. The entire cold-pour denture is made from the same material. An ivory-colored pigment is used to dye the cold-pour acrylic to give the appearance of natural tooth coloring. The teeth on a cold-pour denture absorb stains from food and drinks, such as coffee and tea, and gradually darken. The pink color also lacks stability, which causes eventual fading. The solubility of a denture refers to its ability to dissolve, a slow process, usually undetected by denture wearers. Auto-polymerizing resins have a greater toxic effect than heat-cured acrylics due to the dissolving of chemical components and bacteria-contaminated liquid previously absorbed by dentures.

Best Regards,
