Self-cure acrylic resins have been used mainly in prosthetic dentistry for the construction of custom-built impression trays, occlusion registration bases and for repairing fractured dentures. Recently, pour-type resins have been introduced for the fabrication of denture bases.
What are the differences between heat cured acrylic resin and self-cure acrylic resin?
The principal difference between self-cure and heat-cure resins is that more residual monomer is present in the self-cure resins. In addition, with a high monomer to polymer ratio, residual monomer content in the polymerized acrylic resin would be large.
What is heat cured acrylic resin?
Introduction: Heat cure acrylic resins are the most commonly used denture base materials. The important limitation is they may act as reservoir of microorganisms. The adherence of microorganisms can be reduced by chemical modification of the surface charge of denture base resin.
What is cold cure acrylic resin?
Bonding of cold-curing acrylic resin to acrylic resin teeth increases tooth retention and strengthens denture bases because the plastic teeth become an integral part of the denture base. The bonding was verified in experimental dentures made of a compression molded and a pour type poly(methyl methacrylate).

How do you treat acrylic resin?
In the long curing cycle the acrylic dough was cured at 72 °C for 6.5 h and then 92 °C for 1.5 h. The flasks were left undisturbed in the curing tank for at least 36 h to allow the acrylic resin to cool slowly to the ambient temperature (24–28 °C).
What are acrylic resins used for?
