The Right Brand Helps Control the Color, Porosity, and Conductivity of Your Materials
Because of their chemical properties, acrylic resins are the dental material of choice for denture bases and removable devices. Its polymer chain reaction creates bonds that reduce the chances of shrinkage, heat dispersion, and mold leakage. It has a high aesthetic quality, is cheaper than porcelain, and is also easier to process.
Its natural appearance and dimensional stability give the material a good resistance to bacteria growth and oral fluids. While its strength lacks luster compared to porcelain, acrylic is easier to repair, making it a viable choice for low-income patients. However, choosing the right acrylic for the job involves comparing your materials and understanding some of the chemical changes during polymerization because these factors determine the finished product and your patient’s satisfaction.
Acrylic resins have some major benefits and disadvantages over porcelain: while porcelain has more durability and strength, porcelain’s also more prone to scratching and breakage, unlike acrylic. Acrylic makes up the base of most dentures, and porcelain teeth cannot be bonded to an acrylic denture base. Acrylic doesn’t put as much pressure on the teeth and gums as porcelain, and for patients experiencing bone loss, acrylic helps to retain that support without digging into the sensitive parts of the mouth and jawbone. Although acrylic’s harder to clean due to its more porous indentations, it’s less prone to breakage when cleaning when compared to porcelain.
Acrylic has its benefits, but understanding which acrylic resin to use for the right procedure matters. There are multiple types of resins to choose from that contain acrylic components, including:
Heat-cure resin – Composed of powder and liquid, mixing these components together creates a chemical reaction through heat energy to create the rigid solid resin. Heat-cure resin is processed by creating a dough and then set and packed into a plaster to be squeezed, molded, and trimmed. These kinds of resins experience reduced polymerization shrinkage because of the granules of polymethyl methacrylate within the powder. Its polymerization method is highly exothermic because of the amount of heat produced and typically reaches a maximum temperature of 80 kJ/mol. Although highly volatile and flammable, the polymer powder is stable and has an indefinite shelf life.

Cold-cure resin – Cold-cure resins are identical to heat-cure in their chemistry, but the curing process is initiated by tertiary amine instead of heat. Although not as effective because of its lower molecular weight, it has higher strength properties. Its more prone to discoloration, and its viscosity during its doughy stage can affect the adaptation of the mixture when molding.
Pour-and-cure resin – Pour-and-cure resins aren’t as popular, but when mixed, their sufficient amount of liquid gives an excellent reproduction of surface detail. This surface detail, however, doesn’t compare to heat and cold cures.
Visible light cure resin – Visible light cures have high biocompatibility, low bacterial adherence, and ease of manipulation. The chemistry of these cures has more in common with composite restoratives, which makes differentiating between these two difficult. These resins are made with urethane dimethacrylate, containing a small amount of colloidal silica, and then contain a filler of acrylic beads that become part of the structure when cured. Certain brands such as Eclipse and Dentsply have improved the product’s impact strength and resistance to brittleness, and it’s widely used as a reline material for dentures and repairing fractured dentures.
